[Bug tree-optimization/39300] vectorizer confused by predictive commoning and PRE

[dorit at gcc dot gnu dot org]

--- Comment #5 from dorit at gcc dot gnu dot org  2009-03-08 14:25 ---
This is a known problem... Indeed when Zdenek introduced predictive-commoning
there was a discussion on whether to schedule it before or after vectorization.
AFAIR, it ended up getting scheduled before the vectorizer just because this
happened to be what Zdenek tested/experimented with, and he didn't have a
problem with scheduling it after vectorization as long as it didn't hurt
performance (of mgrid in particular). Here are related threads:
http://gcc.gnu.org/ml/gcc-patches/2007-02/msg01383.html
http://gcc.gnu.org/ml/gcc-patches/2007-02/msg00555.html
http://gcc.gnu.org/ml/gcc-patches/2007-05/msg00571.html

Regardless of whether we scheudule predcom after vectorization, it will still
be useful to teach the vectorizer to handle such dependence patterns, as they
may (and do) appear in the source code.

It is a valid size optimization, so if the unwinder doesn't need the directive
to be always correct, we should do this optimization for -Os unless you also
specify -O1.  Optimization levels above -O1 are known to give imperfect debug
information.  And -O1 defaults to -fno-crossjumping .

Confirmed.

For some reason, we have never added a bounds check to assignments.  The first
testcase uses a check internal to the function.  Once an extra expression is
added to the rhs, there is nothing to check against.

Cheers

To avoid pessimizing code where partially clobbered registers are used
to allocate pseudos which are not affected by the partial clobbers, the
register allocator will have to provide caller_save.c with more information.
It needs to know which registers are live across a call in excess of the part
that is saved.

It seems that stage2 cc1plus is miscompiled on hppa. I suggest you replace
.o files from stage1 and relink stage2 cc1plus to find out which files
are miscompiled by stage1 cc1. You may be to extract a small testcase to
show miscompilation.

Re. comment #5.
Two years without a test case that allows us to reproduce the bug.  REPRODUCE
the bug.  Is that too hard for you to understand?

If we can't reproduce the bug, we can't diagnose the problem and fix the bug.

The test case from comment #0 does not trigger this bug in post-4.0 compilers
(at least, not for the ones I tried, and apparently likewise for Manu).

These tests are bogus.  On FreeBSD, -fopenmp will add the -pthread

properly add the required library, i.e., -lpthread.

don't even know the version number, as it doesn't have an option to print it)
doesn't work the way that the makefile expects. Should I file a separate bug,
for the configure script to check beforehand whether flex supports the -o

That only applies to release tarballs, not snapshots.  You need the same 
developer tools for building from snapshots as for building from SVN 
checkouts.

There is if (optimize) test in inliner to disable copy and constant
propagation. The reason is to preserve debug info, with optimizing we always do
cprop while inlining.

So this patch just enable constant propagation when inlining at !optimize...

I've comitted the fix. Can you please double check that arm is happy?

--- Comment #1 from jsm28 at gcc dot gnu dot org  2009-03-08 23:21 ---
Strongly target-specific bugs that might be considered conformance issues but
are not shown as dependencies because of their target-specific nature
include: bug 323 (the C parts, fixed on c-4_5-branch), bug 545, bug 26374,
bug 37845.  Bug 30484 should probably not be considered a conformance bug
given WG14 discussions.

[Bug c/39401] New: Reproducible internal compiler error for FFmpeg/h264.c; multiple platforms

[contact at multimedia dot cx]

Yay! A reproducible gcc compiler error that occurs on multiple platforms at the
same place.

I periodically upgrade gcc-svn for a number of platforms and continuously test
FFmpeg ( http://ffmpeg.org/ ) on a large number of configurations. I recently
upgraded from 144120, built 2009-02-11 to 144657, built 2009-03-05. That's when
the compilation failed on an unfortunately very large file. However, it's very
repeatable.

Note that this occurs identically on both x86_64-unknown-linux-gnu and
powerpc-unknown-linux-gnu. These are the only I have tested right now but it's
reasonable that the problem occurs on other targets.

Command line:

Please submit a full bug report,
with preprocessed source if appropriate.
See  for instructions.

Attached is the h264.i file generated when adding -save-temps to the compiler
command line. I find that I can trigger the compiler error with this command:

/home/fate/cc/64/gcc-144657-20090305/bin/gcc -c h264.i -O3 -o h264.o

The -O3 is necessary for the error; no error when omitting it.

[Bug c/39403] New: Excessive optimization issue

[casmyu at gmail dot com]

My OS and compiler information as follows:
[root][~]# uname -a
Linux debian 2.6.26-1-686 #1 SMP Sat Jan 10 18:29:31 UTC 2009 i686 GNU/Linux
[root][~]# gcc --version
gcc (Debian 4.3.2-1.1) 4.3.2
Copyright (C) 2008 Free Software Foundation, Inc.

A test C code with inline assembly language as follows:
  1 #include 
  2
  3 int main()
  4 {
  5 char src[30] = {"This is a test message.\n"};
  6 char dst[30];
  7 int len = 25;
  8
  9 __asm__ __volatile__(
 10 "cld\n\t"
 11 "rep movsb"
 12 :
 13 : "S"(src), "D"(dst), "c"(len)
 14 );
 15 printf("%s\t%d\n", dst, len);
 16 return 0;
 17 }

compile the code like this:
[root][~]# gcc -O2 -o bugtest bugtest.c

then run the program, this issue will be re-produced.

I disassembled the binary and found that, when add O2 switch, before the
printf() function invoked, the edi register will be push into the stack instead
of the address of output. So actually, the output of printf is part of the
dst's tail and all the src, not the dst string.
But if did not set O2 switch, this issue will be disappeared.
So I think this is an excessive optimization issue of gcc.
Thank you!

[Bug c++/39404] New: -fpack-struct causes iostream to error, -O3 makes problem worse

[jmichae3 at yahoo dot com]

the act of #including iostream or any of the streams and using the
-fpack-struct switch causes the compiler to flag lots of errors that it
normally wouldn't without the switch. adding -O3 makes the problem worse.

this is a consistent problem.


This problem persists in 5.1.4 version of MinGW (gcc 3.4.5).
Note: this problem persists in gcc 4.32 with djgpp (DOS port of gcc, including,
gcc-3.23, gcc-3.36, gcc-3.44, gcc-4.01, gcc-4.10).
I am using Dell 4600 Windows XP SP3 32-bit on Pentium 4HT (thinks its
dual-core) with 3GB Ram and 4GB Virtual Memory.

[Bug c++/39404] -fpack-struct causes iostream to error, -O3 makes problem worse

Created an attachment (id=17424)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=17424&action=view)
source that #includes fstream which also fails miserably with -fpack-struct

new attachment: source for f.cpp

C:\prj\test\iostreamdos>type f.cpp
#include 
int main(void) {
return 0;
}

C:\prj\test\iostreamdos>g++ -v -save-temps -fpack-struct f.cpp
