Hi,
basically $subject, making some code unconditionally compiled, and changing
other things from #ifdef to #if so they can be made unconditional
incrementally.
patches individually bootstrapped + regtested on x86_64-linux-gnu, and a
slightly earlier version of the series ran through config-list.mk. I think
everything here is either preapproved, or obvious so I'll commit it later
today if nobody complains.
Trev
Trevor Saunders (12):
reduce conditional compilation for HARD_FRAME_POINTER_IS_ARG_POINTER
remove EXTENDED_SDB_BASIC_TYPES
remove conditional compilation of sdb debug info
always define XCOFF_DEBUGGING_INFO
always define VMS_DEBUGGING_INFO
always define DWARF2_DEBUGGING_INFO
always define DBX_DEBUGGING_INFO
always define DWARF2_LINENO_DEBUGGING_INFO
always define TARGET_PECOFF
always define EH_RETURN_HANDLER_RTX
always define HAVE_AS_LEB128
always define ENABLE_OFFLOADING

The last target using this was i960, which was removed many years ago,
so there's no reason to keep it.
gcc/ChangeLog:
2015-11-09 Trevor Saunders <tbsaunde+gcc@tbsaunde.org>
* gsyms.h (enum sdb_type): Remove code for
EXTENDED_SDB_BASIC_TYPES.

From: Trevor Saunders <tbsaunde+gcc@tbsaunde.org>
We need to include gsyms.h before tm.h because some targets (rl78 iirc) define
macros that conflict with identifiers in gsyms.h. This means sdbout.c won't
produce correct output for those targets, but it previously couldn't either
because it wasn't compiled at all.
gcc/ChangeLog:
2015-11-09 Trevor Saunders <tbsaunde+gcc@tbsaunde.org>
* defaults.h: New definition of SDB_DEBUGGING_INFO.
* doc/tm.texi: Regenerate.
* doc/tm.texi.in: Adjust.
* final.c (rest_of_clean_state): Remove check if
SDB_DEBUGGING_INFO is defined.
* function.c (number_blocks): Likewise.
* output.h: Likewise.
* sdbout.c: Likewise.
* toplev.c (process_options): Likewise.

Are these the last patches of this nature planned for GCC6? While the
window was left slightly open by Richi this morning, I think that's more
to allow the queues to drain rather than to allow more new work to go
into the tree :-)

As I said for a previous patch series, if we go to the trouble of fixing
up stuff like this, we might as well do it properly and turn things like
this into a target hook.

In general I think the _DEBUGGING_INFO patches are going to be OK,
modulo Jeff's comment about stage 1. I think they shouldn't have been
split - it causes numerous unnecessary extra changes, and the
intermediate stages look very inconsistent.

This seems to reference vmsdbg_debug_hooks unconditionally, but as far
as I can tell the definition is still guarded by an #if? Does this compile?

This one I would keep guarded with an if.
Otherwise ok modulo stage 1 end.

I agree that pushing hookization further is good as well. I still think
the patch in and of itself is a step forward, even if it doesn't hookize
EH_RETURN_HANDLER_RTX.

There's an easy way for Trevor to find out. Build a cross for one of
the VMS targets (there's 3 defined in config-list.mk) :-)

Well, I was hoping that, by pointing out the issue for the last patch
set, the next set of patches would get things right. We really shouldn't
make sideways steps when there's a simple way to go forward.

yeah, that's more or less my thought, and this makes hookization easier
since you can now mechanically add a hook for each thing in defaults.h
that invokes the macro. Then for each target you can go through and
replace the macro with an override of the hooks. That ends up with the
macros replaced by hooks without writing a lot of patches that need to
go through config-list.mk, and testing on multiple targets which imho is
a giant pain, and rather slow.

This used to be
#if ARG_POINTER_REGNUM != HARD_FRAME_POINTER_REGNUM
and the whole macro seems kind of pointless - why not just make the
ARG_POINTER_REGNUM test unconditional? I think the conditional
compilation was originally just a "performance optimization", avoiding
unnecessary tests - which means the reason to have the tests goes away
if we move away from the conditional compilation.

yeah, I guess I misread, I thought the end was tonight not last night (I
could easily have sent this out a day or so earlier). Given my in
correct assumption about timing I was considering trying to sneak in a
little more around reg-stack.c, but I suspect that isn't going to work
out anyway (turns out even after the macros reg-stack.c uses x86
specific variables).

I'd actually really rather review them, or really deal with them in any
way, the way they are. Smaller simpler patches that only deal with one
thing are much better. I think the most macros that appear on one line
are 2, so at most you could lower that to 1 change instead of 2, but who
really cares anyway? I guess its not the greatest thing for blame, but
good blame tools should make that a tiny issue since uninteresting changes
are a fact of life, and I'd much rather skip uninteresting changes than
look at a giant change doing many things and wonder why it did one of
them.

as I said in 0/12 this did go through config-list.mk, and checking again

The question I have is - why does it build on any other target? It's the
reference that's unconditional, not the definition. Do we have enough
DCE at -O0 to eliminate the reference? It's still incorrect IMO (and
should be fixed in the other patches as well.

We might want to think about making a policy decision to try waiving
some of the testing requirements for target macro -> hook conversions.
Maybe try only a "build to cc1" requirement and see whether that causes
too much breakage.

A config-list.mk build is a build to cc1*, f951, gnat1, so we're not
requiring deep tests on the affected targets. Not sure how much we're
getting by forcing a bootstrap & regression test of that kind of change.
I'm certainly open to this kind of relaxed testing to help this stuff
move forward an complete before we're all retired :-)

Well, with this patch the test should still get optimized away when

yeah it might as well go away.

Testing is a cornerstone of gcc quality. I like it. It is useful. That said, I don’t think we should always be fanatical about it. How and when we accept less that a standard bootstrap and regression test run I’ve sure would be a big topic, but rather than make a ton of rules, I’d rather let small handful of reviewers decide when and how to accept less, and let them do what they want. We can give them negative feedback if it impacts too many people, too often and they can adjust.
The other way, would be to have an integration branch that is tested and merged post testing on a regular basis and let people contribute less than well tested things on it, the idea being that it still won’t hit trunk until after a bootstrap and tests suite run, but that we can bundle 2-100 patches into one test suite run. This strikes me as more scalable, easier for developers and removes the requirement of test suite + bootstrap before checkin while retaining the useful quality of everything merged to trunk is tested. Hardest part about this would be ChangeLogs, merge resolution and svn blame. git handles this gracefully. svn as I recall, a little less so. [ quick check ] Ah, seems svn blame -g TARGET ca n handle this graceful (in theory).

I also looked at that one and initially thought that it can simply go
away, but the earlier test for FRAME_POINTER_REGNUM also has some extra
reload_completed etc. conditions.
So I think this:
! if (!HARD_FRAME_POINTER_IS_FRAME_POINTER
&& regno == HARD_FRAME_POINTER_REGNUM
&& (!reload_completed || frame_pointer_needed))
return hard_frame_pointer_rtx;
-#if !HARD_FRAME_POINTER_IS_ARG_POINTER
if (FRAME_POINTER_REGNUM != ARG_POINTER_REGNUM
&& regno == ARG_POINTER_REGNUM)
return arg_pointer_rtx;
-#endif
should become
! if (HARD_FRAME_POINTER_REGNUM != FRAME_POINTER_REGNUM
&& regno == HARD_FRAME_POINTER_REGNUM
&& (!reload_completed || frame_pointer_needed))
return hard_frame_pointer_rtx;
if (FRAME_POINTER_REGNUM != ARG_POINTER_REGNUM
+ && HARD_FRAME_POINTER_REGNUM != ARG_POINTER_REGNUM
&& regno == ARG_POINTER_REGNUM)
return arg_pointer_rtx;
#endif
and then it should be possible to eliminate the two X_IS_Y macros.

So in general when I've done cross target things I think I've found more
bugs with config-list.mk than with a regtest, but the regtest has found
some things I think.
However I actually don't mind bootstrapping and regtesting that much,
its more or less a few hours for the control and then another few for
each patch. On the other hand config-list.mk takes on the order of 12
hours, and setting up a cross for a quick test isn't really that quick.
Which means that if you have a patch touching a number of targets you
end up not checking it compiles at all until you run config-list.mk, and
then its a heavy weight operation.
So at least for the way I work I'd really rather write series that I can
incrementally test on just one target and be reasonably confident they
won't break other targets.
The add default macro definitions then wrap those with hooks, then
target by target replace the macro by hook overrides approach seems to
provide that you can incrementally test and fiind most of the issues,
but the change a macro every where approach doesn't really.

dce would be my guess. I guess going back to #if ing the bits that
reference it, and then incrementally removing the #ifs starting with the
ones defining the functions used in the structs, but given you seem to
be against patches that only change ifdef to #if you might not likethat

other than reading this now I'm not sure what the context would be, but
either way personally I really don't mind reading that, and think its
simpler to reason about the correctness of one thing at a time.

I'm finding config-list.mk fairly reliable, with the notable exception
of the avr-rtems issue and interix. But that may simply be function of
running it regularly.

I usually save my results and only go back for a control build if
something goes wrong. Of course I'm usually stepping forward at least
once a day, so the number of new tests is usually manageable and allows
me to compare the first run of the day with the last run of the prior day.

FWIW, If we know what ports a particular patch would hit, I'd fully
support folks doing builds that didn't hit all of config-list.mk.
In case it's not obvious I do hope that we'll get to a point where the
class of bugs like "X is unused on port PDQ because it defines/does not
define FROBIT" just go away and we can get good first level coverage
with a native and perhaps a very small number of crosses (instead of the
200+ in config-list.mk now).
At some point I also want to see config-list.mk extended to do things
like "build the crosses and run test tree-ssa/ssa-dom-thread-11.c on all
of them". I've got hacks to do that locally, but they're strictly
hacks. I think this selectively deeper testing will become more
important as we put the first level coverage behind us.

I think Bernd and I just have different approaches, preferences and
priorities on some stuff which results in slightly different priorities
or approaches to certain issues.
I've known Bernd a long time and will say he's very reasonable and his
concerns/objections are well thought out and carry a ton of weight with me.

yeah, its reliable although I tend to find needing to have an installed
trunk compiler a little painful. What I meant was that sometimes I've
made mistakes and introduced testsuite failures or the like.

SO my usual mode is to build up a branch just checking that a default
build works, and then at the end run a script that regtests all the
patches. That can suffer from intermitant tests, but its low human
input so I like it.

yeah, I'd actually like to see config-list.mk become part of the "real"
build system at some point and you could do something like ./configure
--target=i686-linux-gnu,ppc64-linux-gnu,alpha-dec-vms and stuff.

Sure, we're all different ;)

I don't really know him, but I don't really disagree with where he wants
to get to. However I think we work fairly different ways, and review
things differently. When I review patches (mostly for stuff more
directly related to Mozilla my standards are basically it needs to be an
improvement, and it needs to not introduce bugs. So I find the it might
improve things, but it doesn't also accomplish X to berather odd, and
hard to work with if I think getting directly to X might be hard.

I have this notion that once a target macro is "regular" enough - not used
in code built for the target, not used in driver code, not used directly
or indirectly in #if conditions except for the single default definition
in defaults.h, target definitions only depend on the target architecture
and not OS or other variations - it ought to be possible to do the
conversion to a hook with some kind of automated refactoring tool
(possibly with a little editing of its results). And so this sort of
regularizing of target macros is helpful because it increases the number
of target macros that could be converted in an automated manner.

What I like to ask for is to not just make mechanical changes, but to
apply a bit of thought while doing so. Often something better can be
done with the same amount of effort (e.g. if one notices that the
X_POINTER_IS_Y_POINTER macros are pointless). Such small oddities in the
code add up over time, and it is better to eliminate them when making a
change anyway.

In cases where getting to X is hard I'd agree, and the
EH_RETURN_HANDLER_RTX thing isn't the best example since it's defined by
many ports. What disappointed me in the previous patch series were cases
like INITIAL_FRAME_ADDRESS_RTX which is used by only one port. In such a
case I don't think it's unreasonable to point out that we actually want
to get rid of these macros rather than going through an intermediate stage.
Since EH_RETURN_HANDLER_RTX is a slightly different case, and Joseph
said he sees value in the patch, it is OK.

yeah, I kind of have mixed feelings about that, on one hand its
stuff that really should be cleaned up. ON the other hand making it non
mechanical makes it more work than it would be as a mechanical
replacement. I guess it depends how much you value computer time
testing vs human time thinking or something. Also "that seems fine, but
I see we could clean up X" seems nicer to me than "there's
nothing wrong with this, but you might as well do X while your there",
but maybe that's just habbit or something silly.

Well, I guess if you believe Joseph is right about automating
conversion from macros to hooks there's an argument to be made that the
intermediate stage is just fine even for macros with one definition,
because it'll just be two totally mechanical steps. I'm not totally
convinced it'll be easy to automate, but even if its a human making the
work mechanical in my mind makes it easier. On the other hand for
something like BIGGEST_FIELD_ALIGNMENT and ADJUST_FIELD_ALIGN it seems
worth while to take a look at merging those into one hook (of course
after the libojbc stuff is sorted).

There are 2 new uses of "#ifdef ENABLE_OFFLOADING" in c_parser_oacc_declare and
cp_parser_oacc_declare.

It's documented on the Offloading wiki page, but this patch is good
enough if it passes normal testing.
Cc'ing Thomas for any extra testing/fixes that may be needed.

"make check"? ;-) (Offloading currently will happen for OpenACC only if
a nvptx offload target has been configured, though.)
Thanks for the patch -- please commit this as an obvious fixup for the
trunk commit transforming ENABLE_OFFLOADING.
