It looks like GCC on IA64 HP-UX has a problem when a routine in .text.unlikely
calls a function in .text. If I define UNLIKELY_EXECUTED_TEXT_SECTION_NAME and
HOT_TEXT_SECTION_NAME to just be '.text' then I can

Honza, have you had a chance to look at this failure recently? It is still
happening and I can only build GCC on ia64-hp-hpux11.23 using workarounds to
stop some of the inlining.

can't do that I wonder if we should make GCC more conservative

Because the ia64-hp-hpux11.31 compiler generates 32 bit code by default you
cannot do a bootstrap build in 64 bit mode. From install.texi:

I think you will need to create a fde-freebsd.c file in gcc/config/ia64 to
define Unwind_FindTableEntry. See fde-glibc.c and fde-vms.c for examples.

Does freebsd use glibc? Does freebsd have a system libunwind? I am going to
guess yes to the first question and no to the second in which case you need to
edit gcc/config.gcc and modify the 'ia64*-*-freebsd*' entry

The patch worked for me after changing some leading spaces to tabs If you
grabbed it with a cut-n-paste the patch may have had spaces in it instead of
tabs (or perhaps it was put in the report that way). You can either

Dave, did you get any comments on your proposed patch? I just got a bug
report from a GCC user that appears to be this same problem.

I tried (and failed) to reproduce this using msmpeg4.i and compiling with:
gcc -shared -pthread -std=c99 -fomit-frame-pointer -g -O3 -fno-math-errno
-fno-signed-zeros -fPIC -fno-tree-vectorize msmpeg4.i -o x.so
I tried

It looks like a patch has been checked in to fix this bug, is there any reason
we can't close this defect?

Has a patch to move update_equiv_regs into its own pass been submitted?
I don't see one and IA64 is still producing the 'wrong' scheduling.

I thought the report and log was clear enough on the fact that this is
indeed a problem that only arises during the final link. If not, then
now it is ;)
I guess the point I was trying to make is that I don't think

I am not sure if this would help or not but it might be interesting to try the
-mno-sdata flag on the compilation to see if that helps. By default GCC on
IA64 will use .sbss (short bss) and .bss (normal bss) sections

The patch I checked in provides the infrastructure to fix this problem and I
have fixed the IA64 instance of it but other targets (like x86) will need to
define TARGET_OVERRIDE_OPTIONS_AFTER_CHANGE as well to completely

I haven't had a chance to test it on PA yet but it fixes the problem on
Itanium.

I see failures for this test on IA64 HP-UX and Linux as well.

This looks like a duplicate of 41086. I see it on IA64 HP-UX and Linux as
well.
