[Bug bootstrap/32581] New: make profiledbootstrap - stageprofile - gcc/ada/a-except.adb:1301: error: control flow in the middle of basic block 20

My other report mentions "GNAT BUG DETECTED ada/ali.adb:2265"
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32024

Shows breakage in a different location of the build. That report was concerned
with fold checking and was closed on the basis that non-profiled make was
fixed.


The following bug report claims "make profiledbootstrap" was FIXED @ 121554 but
does not mention if they built Ada, and it was at latest from 20070202:

[4.3 Regression] ICE with -fprofile-use
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30650


I do not believe my search turned up any dupes and that this report is new.


One problem _might_ be that when the "GNAT BUG DETECTED" 'box' comes up it
doesn't list files that are to be included with the report (as shown in my
other bug report above http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32024#c5 ).

The bug that this report is the subject of is when I do a "make
profiledbootstrap" after configuring like this:

Note that it says "Please include these source files with error report" but
there are no files listed.

The subject of this report is not that fault but that I can not use "make
profiledbootstrap" with all languages enabled. I'll strip Ada off the list and
see if I can re-start the build without a "make clean".

The reason I don't want to type "make clean" is that each file over 700K takes
a while with profiling on and a few are over a meg, thus quite slow.


The worst is this:

ls -lrtA /opt/gcc-4_3-build-profile-1/gcc/
...
-rw-r--r-- 1 root root       10 Jul  1 22:07 s-attrtab

-rw-r--r-- 1 root root   712157 Jul  1 22:28 insn-automata.c
...

I had a look at the generated file "insn-attrtab.c" and it would be possible to
break it into three pieces (at least). Another offender is "insn-recog.c" which
might be harder to find a good spot to split it.

The file "fold-const.c" is not generated and could be split. I might be where
the above problem is. It takes 10 minutes to compile (on a fast computer).

The 35 minutes spent compiling those three files might be better spent
splitting them up. Then they would compile fast enough to get your time
back for the effort expended _if_ you only had to compile it once.

[Bug bootstrap/32581] make profiledbootstrap - stageprofile - gcc/ada/a-except.adb:1301: error: control flow in the middle of basic block 20

[rob1weld at aol dot com]

------- Comment #1 from rob1weld at aol dot com  2007-07-02 17:47 -------
I re-configured with exactly the same command line options, except I removed
ada from "--enable-languages=", and re-started make.


On this second attempt the file building timing was similar to what was
previously reported. It appears the link time was 20 minutes here:

# ls -lrtA gcc-4_3-build-profile-1/prev-gcc/
...
-rw-r--r--  1 root root     2108 Jul  2 06:32 crtbeginS.o

-rw-r--r--  2 root root     3904 Jul  2 06:53 tlink.gcda
-rw-r--r--  2 root root     5968 Jul  2 06:53 collect2.gcda
-rw-r--r--  2 root root     1360 Jul  2 07:13 web.gcda
-rw-r--r--  2 root root      688 Jul  2 07:13 vec.gcda
all the remaining 'data files' had the same time - at leasr that was fast as
was the last successful pass in gcc-4_3-build-profile-1/gcc .


Here is where it broke:

On my first attempt I typed this, and I got this:

# grep Configuring\ stage gcc-4_3-build-profile-1/make_29a_log.txt
Configuring stage 1 in ./intl
Configuring stage 1 in ./gcc

On my second attempt I typed this, and I got this:

Configuring stage feedback in ./intl
Configuring stage feedback in ./gcc
Configuring stage feedback in ./libiberty
Configuring stage feedback in ./zlib
Configuring stage feedback in ./libcpp
Configuring stage feedback in ./libdecnumber


On my first attempt I typed this, and I got this:

# grep execution\ counts\ estimated
/opt/gcc-4_3-build-profile-1/make_29a_log.txt
(prints nothing)

On my second attempt I typed that, and I got a huge list which is attached.

this bug seems to appear only with profiledbootstrap. i'm able to do normal

I have since switched target platforms and can not test your patch but thank
you kindly for fixing the bug I reported on 2007-07-02. 


It only took 14 months for everyone to be annoyed with this breakage for
someone (great) to fix it.


Leaving such a bug in for so long only served to foul the code and to prove
that something was not correct leaving other portions suspect. Removing the bug
instills greater confidence in that portion of the code and indeed leads one to
imagine that the rest of gcc is now better for it. For this we all thank you.

Rob

PS: Did I mention that I was really ticked off that profiling was broken :) .

Could this change be merged down to the 4.3 branch? Currently 4.3.2 release is
still broken.
