To: gcc-patches, mliska, segher; +Cc: Egeyar Bagcioglu
Hello,
I would like to propose the second version of the patches which introduce a compile option --record-gcc-command-line. When passed to gcc, it saves the command line invoking gcc into the produced object file. The option makes it trivial to trace back with which command a file was compiled and by which version of the gcc. It helps with debugging, reproducing bugs and repeating the build process.
The reviews addressed in this version include indentation changes, error handling and corner case coverage pointed out by Segher Boessenkool in the first two patches; while the new third patch is another corner case (lto) coverage requested by Martin Liska.
Although we discussed after the submission of the first version that there are several other options performing similar tasks, I believe we established that there is still a need for this specific functionality. Therefore, I am skipping in this email the comparison between this option and the existing options with similarities.
This functionality operates as the following: It saves gcc's argv into a temporary file, and passes --record-gcc-command-line <tempfilename> to cc1 or cc1plus. The functionality of the backend is implemented via a hook. This patch includes an example implementation of the hook for elf targets: elf_record_gcc_command_line function. This function reads the given file and writes gcc's version and the command line into a mergeable string section, .GCC.command.line. It creates one entry per invocation. By doing so, it makes it clear which options were used together in a single gcc invocation, even after linking.
Here is an *example usage* of the option:
[egeyar@localhost save-commandline]$ gcc main.c --record-gcc-command-line
[egeyar@localhost save-commandline]$ readelf -p .GCC.command.line a.out
String dump of section '.GCC.command.line':
[ 0] 10.0.1 20200227 (experimental) : gcc main.c --record-gcc-command-line
The following is a *second example* calling g++ with -save-temps and a repetition of options, where --save-temps saves the intermediate file, main.cmdline in this case. You can see that the options are recorded unprocessed:
[egeyar@localhost save-commandline]$ g++ main.c -save-temps --record-gcc-command-line -O0 -O2 -O3 -DFORTIFY=2 --record-gcc-command-line
[egeyar@localhost save-commandline]$ readelf -p .GCC.command.line a.out
String dump of section '.GCC.command.line':
[ 0] 10.0.1 20200227 (experimental) : g++ main.c -save-temps --record-gcc-command-line -O0 -O2 -O3 -DFORTIFY=2 --record-gcc-command-line
The first patch of this three-patch-series only extends the testsuite machinery, while the second patch implements the functionality and adds a test case for it. The third patch that alters libiberty is to make sure the .GCC.command.line section in LTO objects survive the linking and appear in the linked object.
In addition to the new test case, I built binutils as my test case after passing this option to CFLAGS. The added .GCC.command.line section of ld.bfd listed many compile commands as expected. Tested on x86_64-pc-linux-gnu.
Please review the patches, let me know what you think and apply if appropriate.
Regards
Egeyar

This patch is for .GCC.command.line sections in LTO objects to be copied
into the final objects as in the following example:
[egeyar@localhost lto]$ gcc -flto -O3 demo.c -c -g --record-gcc-command-line
[egeyar@localhost lto]$ gcc -flto -O2 demo2.c -c -g --record-gcc-command-line -DFORTIFY=2
[egeyar@localhost lto]$ gcc demo.o demo2.o -o a.out
[egeyar@localhost lto]$ readelf -p .GCC.command.line a.out
String dump of section '.GCC.command.line':
[ 0] 10.0.1 20200227 (experimental) : gcc -flto -O3 demo.c -c -g --record-gcc-command-line
[ 56] 10.0.1 20200227 (experimental) : gcc -flto -O2 demo2.c -c -g --record-gcc-command-line -DFORTIFY=2

As mentioned above, I used binutils as the sample project to compile
with --record-gcc-command-line. I am attaching to this email the file
produced by the command "readelf -p .GCC.command.line ld/ld-new >
ld.commandline.out". You can see in it, all the gcc invocations whose
output is merged into ld.bfd.

We're now using git-style commit messages with self-contained explanation
/ justification of the change being committed.
This means that one of the commit messages (not just message 0, whose
contents don't go in a commit message) for an individual patch should have
the explanation, which should include the self-contained justification by
reference to comparison with other existing similar options. People
should be able to find the relevant information in the commit without
needing to search the list archives for reviews of a previous patch
version.

Mentioning -frecord-gcc-switches will be much appreciated.
How is the new .GCC.command.line different?
Does it still have the SHF_MERGE | SHF_STRINGS flag?
If you change the flags, the .GCC.command.line section may not play with
another object file (generated by -frecord-gcc-switches) whose .GCC.command.line is
SHF_MERGE | SHF_STRINGS.
When both -frecord-gcc-switches and --record-command-line are specified,
is it an error?

--record-gcc-command-line is not a FSF GCC option, there's
-frecord-gcc-switches though which
(also) populates .GCC.command.line
OK.

When passed to gcc, it saves the command line invoking gcc into the produced object file. The option makes it trivial to trace back with which command a file was compiled and by which version of the gcc. It helps with debugging, reproducing bugs and repeating the build process.

Great, thanks for working on that.
Based on the mentioned disadvantages of -frecord-gcc-switches, where each option entry is put into a mergeable section and
so one can't disambiguate in between multiple command line options, I would suggest to replace -frecord-gcc-switches
functionality with what --record-gcc-command-line does. Moreover, looking at clang:
https://reviews.llvm.org/D54487, their current implementation of -frecord-gcc-switches does the very same:
$ clang main.c -frecord-gcc-switches -c
$ readelf -p .GCC.command.line main.o
String dump of section '.GCC.command.line':
[ 1] /usr/bin/clang-9.0.1 main.c -frecord-command-line -c
One additional advantage is that driver options also catch macros (like -D_FORTIFY_SOURCE), which
is also what clang does.
It's question to Nick who originally implemented the option. Nick, are you fine with that?
If I'm correct you're using the annobin plugin and this can help you to replace it?

The functionality of the backend is implemented via a hook. This patch includes an example implementation of the hook for elf targets: elf_record_gcc_command_line function. This function reads the given file and writes gcc's version and the command line into a mergeable string section, .GCC.command.line. It creates one entry per invocation. By doing so, it makes it clear which options were used together in a single gcc invocation, even after linking.

One small nit: I would not send in 3 parts, as the first and last one are just one hunks.

Right. This is also necessary for preserving the outcome of
-frecord-gcc-switches option and that issue is reported to me by Martin
Liska.

Thanks Richard.
I do not have write-access to the GCC repo. I'd be glad if someone

I think there is a misunderstanding here.
I have just implemented --record-gcc-command-line. I have been testing
it and no it does not act as -frecord-gcc-switches.

This option is similar to -frecord-gcc-switches. However, they have
three fundamental differences: Firstly, -frecord-gcc-switches saves the
internal state after the argv is processed and passed by the driver. As
opposed to that, --record-gcc-command-line saves the command-line as
received by the driver, with the exception of extending @files first.
Secondly, -frecord-gcc-switches saves the switches as separate entries
into a mergeable string section. Therefore, the entries belonging to
different object files get mixed up after being linked. The new
--record-gcc-command-line, on the other hand, creates one entry per
invocation. By doing so, it makes it clear which options were used
together in a single gcc invocation. Lastly, --record-gcc-command-line
also adds the version of the gcc into this single entry to make it clear
which version of gcc was called with any given command line. This is
useful in cases where .comment section reports multiple versions.
While there are also similarities between the implementations of these
two options, those implementations are completely independent. These
commands can be used separately or together without issues. I used the
same section that -frecord-gcc-switches uses on purpose, so that they
can also be used together to save both the command line given to GCC and
the internal switches passed by GCC.
The option -grecord-gcc-switches is similar to -frecord-gcc-switches,
but saves the internal GCC switches into DWARF. Lastly, -fverbose-asm
option saves the switches into the assembly file but that information
never makes it to the object files.

Thanks for telling me. I will extend the above comparison according to
the questions I might receive. Then I'll add it, together with the
explanation in the cover letter, into the commit message of the second
patch.

I should add here that both Martin Liska and Nick Clifton mentioned
during the last round of discussion the importance of capturing options
such as -D_FORTIFY_SOURCE which is apparently not distinguished by
--frecord-gcc-switches. The option I am suggesting,
--record-gcc-command-line, saves that without any special case handling.

Here is an old example from the previous discussion, calling g++ with
both -frecord-gcc-switches and --record-gcc-command-line for comparison:
[egeyar@localhost save-commandline]$ g++ main.c
--record-gcc-command-line -frecord-gcc-switches
[egeyar@localhost save-commandline]$ readelf -p .GCC.command.line a.out
String dump of section '.GCC.command.line':
[ 0] 10.0.0 20191025 (experimental) : g++ main.c
--record-gcc-command-line -frecord-gcc-switches
[ 5c] -D_GNU_SOURCE
[ 6a] main.c
[ 71] -mtune=generic
[ 80] -march=x86-64
[ 8e] --record-gcc-command-line /tmp/ccgC4ZtS.cmdline
Above, the first entry in the .GCC.command.line section is saved by
--record-gcc-command-line; while the rest of the entries are added by
-frecord-gcc-switches.

Can we please wait? I'm really convinced we do not want one another very similar
functionality. I would definitely recommend to change the semantics
of -frecord-gcc-switches to what the patchset does.
That's why I added Nick as he's the author of the original implementation.
Reasoning is provided in my previous email.

Also, what is the reason for storing the option in a file, rather than say
putting them into an environment variable from which the backend can pick it
up? I must say I don't really see advantages of this over
-grecord-gcc-switches, recording all options looks very bloaty and will
include mostly stuff you don't really care about (such as, e.g. the -I
options without knowing what was the current directory when the source file
has been compiled), on the other side will not record interesting options
that -grecord-gcc-switches records (say, if some code is compiled with
-march=native, this new option will record that, rather than what it really
is), but I won't stand in a way unless such an option would be on by
default.

That's smart suggestion! It would not be the first environment variable that
we use, right?

Yes, it's a minor disadvantage. On the other hand one can check the fortify
macros. I don't care much about them too, but what's the biggest benefit to me
is that each argument will not go into it's own mergeable section. Then
you will not see something like:
$ gcc -O0 foo.c -frecord-gcc-switches -c -g
$ gcc -Ofast bar.c -frecord-gcc-switches -c -g0
$ gcc foo.o bar.o
$ readelf -p .GCC.command.line a.out
String dump of section '.GCC.command.line':
[ 0] foo.c
[ 6] -mtune=generic
[ 15] -march=x86-64
[ 23] -g
[ 26] -O0
[ 2a] -frecord-gcc-switches
[ 40] bar.c
[ 46] -g0
[ 4a] -Ofast
The output is useless and can't disambiguate each compiler
invocations.

Well, the fortify macro is questionable, because as a macro, it can be
either specified on the command line, or e.g. defined in the source before
including headers, so -g3 seems much better way to query it.

Sure, I'm not talking about -frecord-gcc-switches, that option is indeed
not really useful.

I am sorry. I thought Richard's comment was only about the third patch,
which is also necessary for the current -frecord-gcc-switches.
Therefore, my reply was only for that patch as well.

I needed to pass that information from one process to the other and I
picked a way to do so. Moreover, passing files is what gcc does;
therefore, it didn't seem unnatural to do so. Furthermore, gcc specs
already has its way to create temporary file names so I didn't have to
worry about what level of thread safety is acceptable. If you tell me
why an environment variable is better, we can discuss and I might
implement that too.

1) -grecord-gcc-switches is quite similar to -frecord-gcc-switches and
my first and main arguement about the latter is valid for the former:
You cannot easily construct the right command line to invoke the same
compilation from the switches. Switches are useful to check that the
compiler is doing the expected. The command line is useful when you want
the compiler to do the same thing again.
2) The output is exactly what gcc takes as command line to make that
compilation. It is bloaty, surely, when so is what's provided to gcc to
make it compile as desired. On the other hand, -grecord-gcc-switches is
just much bloatier since it does not work alone. It's embedded in dwarf.
3) Many systems automatically strip dwarf, together with this
information. I do not think there is an easy way to separate this
information and keep it.
Since this comes up often, I'd like to emphasize that the internal
switches of gcc are different than the user-given options of gcc. The
purpose of this new option is really to catch the user given options of
gcc and only them, so much so that I mark it SWITCH_IGNORE within the
specs to avoid it propagated to any child processes of gcc. This option
is simply to retrieve how the call was made to GCC. Currently, there are
no other options giving us this information.

I totally agree that this should not be on by default.

-grecord-gcc-switches also allows to match the options used to the
actual generated code while both -frecord-gcc-switches and
--record-gcc-command-line
end up as ELF comment sections not associated with particular
code pieces.
So IMHO anything but -grecord-gcc-switches is quite useless in case options
used do not match for all object files.

Yes, my comment / approval was only about preserving the early compile
options for LTO. I'll commit that piece momentarily.

Hi.
I'm sending the updated patch based on Egeyar's work.
It utilizes a new environmental variable and uses the currently
existing -frecord-gcc-switches option.
Thoughts?

I hear that. I am definitely not arguing against the use cases where
-grecord-gcc-switches is the best option. But this patch is coming from
the point of view of a different use case at hand. We need to have the
frontend command line saved in a way that it can be later extracted from
the ELF object (including shared libraries and binaries) and be used to
re-compile individual objects, producing more or less the same generated
code. This patch is not enough to get the exact same output, but it is
necessary for us.
Correct me if I am wrong, but none of the existing options are very
helpful when it comes to asking gcc to do the same thing that it did
while creating that object. They hint some things about the command line
but do not help much reconstructing the command line. That is what I
mean when I say this option is not about the internals of gcc. It is
definitely not about knowing what's passed to the backend. As long as
this option's output is concerned, gcc is a blackbox. This is about the
command-line, about higher-level users' interaction with the driver and
nothing more.

Hi.
I'm sending enhanced patch that makes the following changes:
- a new option -frecord-gcc-switches-format is added; the option
selects format (processed, driver) for all options that record
GCC command line
- Dwarf gen_produce_string is now used in -fverbose-asm
- The .s file is affected in the following way:

That's the biggest change I made, but I hope it's acceptable.
Apart from that the patch simplifies and unifies places where save_decoded_options
options are transformed back to string representation.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.
Ready to be installed in next stage1?
Thanks,
Martin

Hi Martin,
I like the patch. It definitely serves our purposes at Oracle and
provides another way to do what my previous patches did as well.
1) It keeps the backwards compatibility regarding -frecord-gcc-switches;
therefore, removes my related doubts about your previous patch.
2) It still makes use of -frecord-gcc-switches. The new option is only
to control the format. This addresses some previous objections to having
a new option doing something similar. Now the new option controls the
behaviour of the existing one and that behaviour can be further extended.
3) It uses an environment variable as Jakub suggested.
The patch looks good and I confirm that it works for our purposes.
Having said that, I have to ask for recognition in this patch for my and
my company's contributions. Can you please keep my name and my work
email in the changelog and in the commit message?
Thanks
Egeyar

Provides the target with the ability to record the gcc command line
switches that have been passed to the compiler, and options that are
-enabled. The @var{type} argument specifies what is being recorded.
-It can take the following values:
-
-@table @gcctabopt
-@item SWITCH_TYPE_PASSED
-@var{text} is a command line switch that has been set by the user.
-
-@item SWITCH_TYPE_ENABLED
-@var{text} is an option which has been enabled. This might be as a
-direct result of a command line switch, or because it is enabled by
-default or because it has been enabled as a side effect of a different
-command line switch. For example, the @option{-O2} switch enables
-various different individual optimization passes.

-time @var{type} is SWITCH_TYPE_DESCRIPTIVE and @var{text} is NULL, the
-warning is for start up and the second time the warning is for

Hi Martin,
I noticed that some comments in the patch were still referring to
--record-gcc-command-line, the option I suggested earlier. I updated
those comments to mention -frecord-gcc-switches-format instead and also
added my name to the patch as you agreed above. I attached the updated
patch. We are starting to use this patch in the specific domain where we
need its functionality.

Egeyar

Provides the target with the ability to record the gcc command line

-@var{text} is a command line switch that has been set by the user.
-
-@item SWITCH_TYPE_ENABLED
-@var{text} is an option which has been enabled. This might be as a
-direct result of a command line switch, or because it is enabled by
-default or because it has been enabled as a side effect of a different
-command line switch. For example, the @option{-O2} switch enables

Hello.
Please note that patch review can sometimes take some time.
You can still install the patch to your local branch and note that
the next major release will be released in about 9 months.

Yes, I understand.
However, this patch has been submitted for review since March this year, 4 months passed.
Just want to make sure that this patch is not ignored and someone will take a look at it.

Our production build of GCC needs this patch for our important application.
So, if this patch will be changed due to some new comments from the reviewers, the back porting will
Need to be redone later, it’s really not convenient for us.
I am hoping the review process of this patch can be done soon, it has been waiting for so long time already.
Thanks.

No, it's not ignored and I you can rely on that it will appear in GCC 11.1.

Thanks a lot for ping this patch again.
Hopefully it can be committed into GCC 11 very soon.

Jakub and Jeff,
PING^7 on the following patch proposed 8 months ago for gcc11:
https://gcc.gnu.org/pipermail/gcc-patches/2020-March/542198.html <https://gcc.gnu.org/pipermail/gcc-patches/2020-March/542198.html>
The deadline for gcc11 stage 1 is approaching. The pinged patch is one that has been sent for review 8 months ago in order to
Make into gcc11.
And this is an important feature that our company is waiting for a long time.
Could you please take a look at this patch and let us know whether it’s ready for commit into gcc11?
Thanks a lot.
Qing

Hello.
You didn't miss the deadline as all patches sent before stage1 can be reviewed even during stage3.
Note that many upstream developers (and maintainers) were busy with feature development and now
will be more time for a review.
Thanks for patience. You can bet on having that in GCC 11.1.0

So while I like the addition of -frecord-gcc-switches-format to preserve
backward compatibility there are IMHO several issues with the patch.
For one, the target hook change to a void(void) hook makes it need to
duplicate too much internals. Please make it take a const char *
argument, the actual text to output.
For second, I see no good reason to have different handling of
-grecord-gcc-switches vs. -frecord-gcc-switches - they should
produce the same content and thus -frecord-gcc-switches-format
should apply to -grecord-gcc-switches as well.
Now - I think what we output into the assembly file with -fverbose-asm
should _always_ be the processed arguments since the assembly
is produced by cc1, not gcc.
+/* Return value of env variable GCC_DRIVER_COMMAND_LINE if exists.
+ Otherwise return empty string. */
+
+const char *
+get_driver_command_line ()
+{
+ const char *cmdline = getenv ("GCC_DRIVER_COMMAND_LINE");
+ return cmdline != NULL ? cmdline : "";
+}
I think silently emitting nothing is not a good idea. In particular using
the environment to carry the driver command-line makes it difficult
to reproduce output with pasting commands as dumped by -v [-save-temps].
Likewise the driver seems to always populate GCC_DRIVER_COMMAND_LINE
even if not needed - why not look for -frecord-gcc-switches-format before
doing so? I'd make -frecord-gcc-switches-format a driver only option
(only the driver can do sth about it) and amend -frecord-gcc-switches
with a -frecord-gcc-switches=FILE variant specifying the content. The
driver would then substitute -frecord-gcc-switches-format=driver
with -frecord-gcc-switches=tempfile and dump the command line into
tempfile. cc1 can then pick contents from tempfile or use the processed
variant if no contents are specified.

Agree with that, nice improvement.

They do. Both respect the newly added -frecord-gcc-switches-format argument.

All right, changed that.

I've just rewritten that to -frecord-gcc-switches-file option. Note that
we can't transform that to -frecord-gcc-switches=FILE as one can use:
-g frecord-gcc-switches-format=driver and so -frecord-gcc-switches is off.
Thoughts on the new version of the patch?

-@var{text} is an option which has been enabled. This might be as a
-direct result of a command line switch, or because it is enabled by
-default or because it has been enabled as a side effect of a different
-command line switch. For example, the @option{-O2} switch enables
-various different individual optimization passes.
-
-@item SWITCH_TYPE_DESCRIPTIVE
-@var{text} is either NULL or some descriptive text which should be
-ignored. If @var{text} is NULL then it is being used to warn the
-target hook that either recording is starting or ending. The first
-time @var{type} is SWITCH_TYPE_DESCRIPTIVE and @var{text} is NULL, the
-warning is for start up and the second time the warning is for
-wind down. This feature is to allow the target hook to make any
-necessary preparations before it starts to record switches and to
-perform any necessary tidying up after it has finished recording
-switches.

-@item SWITCH_TYPE_LINE_START
-This option can be ignored by this target hook.

But the driver can check whether -frecord-gcc-switches is on with
sth like %{frecord-gcc-switches:%{frecord-gcc-switches-format=driver:-frecord-gcc-switches=%b}}
or so. But I don't mind a separate -frecord-gcc-switches-file option.
Guess we need it anyway since -g implies -grecord-gcc-switchs and that
needs the info as well.
> Thoughts on the new version of the patch?
Can you split out the unifying of -[gf]record-gcc-switches processing
and the target hook adjustment from the change introducing
-frecord-gcc-switches-format?
dwarf2out.c seems to retain its gen_producer_string () even though
you duplicate it elsewhere and it is now unused? Please retain
the gen_producer_string name since the function does actual
processing and not just fetch a precomputed string from somewhere.
I'd like somebody else chime in on the -frecord-gcc-switches-format
driver handling but will happily work with getting the unification part merged.

Provides the target with the ability to record the gcc command line

It survives testing.
There's the second part which adds -frecord-gcc-switches-format.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.
Thanks,

so I wonder whether this regresses (no newlines anymore, no separate

like
options passed: -v

-isystem ./include -isystem ./include-fixed t.c -mtune=generic

-fdelete-null-pointer-checks -fdevirtualize -fdevirtualize-speculatively
-fdwarf2-cfi-asm -fearly-inlining -feliminate-unused-debug-symbols
...
but after the change it will most definitely _not_ include all the -f options
implied by -O2? So how does a standard -O2 -fverbose-asm compare?
How does -Q -v compare? How does the producer string in dwarf
compare (I guess that's actually equal since we now use that reporting style).

Richard.

Yes, dwarf output is the same:
BEFORE:
<c> DW_AT_producer : (indirect string, offset: 0x0): GNU C17 11.0.0 20201123 (experimental) -dumpbase-ext .c -mtune=generic -march=x86-64 -g

So the question is: do we really need to preserve the "options enabled" report? It's far from being complete
as it e.g. ignores enum options like:
-fsched-stalled-insns-dep=<number>
-fsched-stalled-insns=<number>
-fsimd-cost-model=[unlimited|dynamic|cheap|very-cheap] unlimited
-fstack-check=[no|generic|specific]
-fstack-reuse=[all|named_vars|none] all
...
Well, gcc -Q -help=optimize <options_used> seems a better hint for me.
Thoughts?

Martin

I don't think it's important to preserve the 'options enabled' part
since the actual
options printed should allow to reproduce it. But what's clearly
inferior is that
the options are no longer separated from the version string and the
'options passed:' is missing.
Can we somehow preserve this by making the helper produce separate
strings for the 'GNU C17 11.0 ...' part and the options passed part? So the
-fverbose-asm and -Q consumer can continue to nicely print the option part?

Yep, good idea. I've just done that and I have:
1) -Q output now:
GGC heuristics: --param ggc-min-expand=30 --param ggc-min-heapsize=4096
options passed: -dumpbase-ext .c -mtune=generic -march=x86-64 -g -O2
and
GGC heuristics: --param ggc-min-expand=30 --param ggc-min-heapsize=4096
options passed: ./xgcc -B. -Q -v /home/marxin/Programming/testcases/a.c -c -O2 -fverbose-asm -frecord-gcc-switches-format=driver -g -S
2) For -fverbose-asm:
# GGC heuristics: --param ggc-min-expand=30 --param ggc-min-heapsize=4096
# options passed: -dumpbase-ext .c -mtune=generic -march=x86-64 -g -O2
and
# GGC heuristics: --param ggc-min-expand=30 --param ggc-min-heapsize=4096
# options passed: -dumpbase-ext .c -mtune=generic -march=x86-64 -g -O2 -frecord-gcc-switches-file=/tmp/ccm3kL7d.cmdline
3) DWARF producer:
<c> DW_AT_producer : (indirect string, offset: 0x97): GNU C17 11.0.0 20201204 (experimental) -dumpbase-ext .c -mtune=generic -march=x86-64 -g -O2
and
<c> DW_AT_producer : (indirect string, offset: 0x27): GNU C17 11.0.0 20201204 (experimental) ./xgcc -B. -Q -v /home/marxin/Programming/testcases/a.c -c -O2 -fverbose-asm -frecord-gcc-switches-format=driver -g
Thoughts?
Thanks,
Martin

handling of the dwarf_record_gcc_switches option.
(dwarf2out_early_finish): Use moved gen_producer_string
function.
* opts.c (gen_producer_string): New.
* opts.h (gen_producer_string): New.
* target.def: Change type of record_gcc_switches.
* target.h (enum print_switch_type): Remove.
(elf_record_gcc_switches): Change first argument.
* toplev.c (MAX_LINE): Remove.
(print_to_asm_out_file): Likewise.
(print_to_stderr): Likewise.
(print_single_switch): Likewise.
(print_switch_values): Likewise.
(init_asm_output): Use new gen_producer_string function.
(process_options): Likewise.
* varasm.c (elf_record_gcc_switches): Just save the string argument
to the ELF container.

+@deftypefn {Target Hook} void TARGET_ASM_RECORD_GCC_SWITCHES (const char *@var{})
Provides the target with the ability to record the gcc command line
-switches that have been passed to the compiler, and options that are
-enabled. The @var{type} argument specifies what is being recorded.
-It can take the following values:
-
-@table @gcctabopt
-@item SWITCH_TYPE_PASSED
-@var{text} is a command line switch that has been set by the user.
-
-@item SWITCH_TYPE_ENABLED
-@var{text} is an option which has been enabled. This might be as a
-direct result of a command line switch, or because it is enabled by
-default or because it has been enabled as a side effect of a different
-command line switch. For example, the @option{-O2} switch enables
-various different individual optimization passes.
-
-@item SWITCH_TYPE_DESCRIPTIVE
-@var{text} is either NULL or some descriptive text which should be
-ignored. If @var{text} is NULL then it is being used to warn the
-target hook that either recording is starting or ending. The first
-time @var{type} is SWITCH_TYPE_DESCRIPTIVE and @var{text} is NULL, the
-warning is for start up and the second time the warning is for
-wind down. This feature is to allow the target hook to make any
-necessary preparations before it starts to record switches and to
-perform any necessary tidying up after it has finished recording
-switches.

-This option can be ignored by this target hook.

To be honest, we moved back to the original implementation which used
a temporary file. There hasn't been any opinion for last 8 months :(

Using environment variable rather than a temporary file must be faster.

But it's difficult to preserve behavior with -save-temps and execing cc1
as printed which is why I don't like it too much, even if it is "faster".
The environment might also be of limited size and with including
everything (-I... -L...) and always (a defect of the patch) I fear we might
run over its size limits on some host OSs at least.

There's a small clean up that removes Report as it's not used
any longer by -fverbose-asm.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.
Ready to be installed?
Thanks,

Subject: [PATCH 1/2] Remove Report keyword for options
Since g:7caa49706316e650fb67719e1a1bf3a35054b685 the option is ignored
as we print used command line for -fverbose-asm output.
gcc/ChangeLog:
* doc/options.texi: Remove Report keyword.
* opt-functions.awk: Print error when Report keyword
is used.
* optc-gen.awk: Do not handle Report keyword.
* opts.h (struct cl_option): Remove cl_report bitfield flag.

ENOPATCH, but same as 1/1 of this series. OK by me given I can guess

+Target Mask(ACCUMULATE_OUTGOING_ARGS)
Accumulate outgoing function arguments and acquire/release the needed stack space for outgoing function arguments in function prologue/epilogue. Without this option, outgoing arguments are pushed before calling a function and popped afterwards. This option can lead to reduced code size for functions that call many functions that get their arguments on the stack like, for example printf.

When accessing RAM, use X as imposed by the hardware, i.e. just use pre-decrement, post-increment and indirect addressing with the X register. Without this option, the compiler may assume that there is an addressing mode X+const similar to Y+const and Z+const and emit instructions to emulate such an addressing mode for X.

To be honest it's only removal of a dead code. Hope it's fine to install the patch now.
I'm planning to work some changes related to options and I would appreciate the clean up
to be installed now. That said, I'm going to push the changes.

Hello, Martin,
Our testing detected unexpected -dumpbase-ext options making to the
producer string.
I tracked it down to something weird that happened in this patch:

Assuming you didn't really mean to drop the option, the following patch
restores it to the exclusion list in the refactored gen_producer_string.
Regstrapped on x86_64-linux-gnu, installing as obvious.
drop -dumpbase-ext from producer string
From: Alexandre Oliva <oliva@adacore.com>
The -dumpbase and -dumpdir options are excluded from the producer
string output in debug information, but -dumpbase-ext was not. This
patch excludes it as well.
for gcc/ChangeLog
* opts.c (gen_command_line_string): Exclude -dumpbase-ext.

Hello.
Thank you for the fix. Yes, it was not an intentional change from my side.

Hello.
Based on discussion with Richi, I'm re-sending the patch. Note that the patch
has been waiting for a review for almost one year and I would like to see
it in GCC 11.1.
Thank you,

Hello,
What’s the status of this patch now? Is there any major technical issue with the patch?
Our company has been waiting for this patch for almost one year, we need it for our important application.
Could this one be approved and committed to gcc11?
Thanks.
