[Bug bootstrap/22313] [4.1 Regression] gcc HEAD as of 2005/07/05 fails to profiledbootstrap

[ian at airs dot com]

------- Comment #7 from ian at airs dot com  2005-10-05 23:36 -------
This is not a bug in the assembler.  The attached assembler code is trying to
put the difference between a symbol in the .text section (.LCFI10) and the
.text.unlikely section (.LCFI11) into the .debug_frame section.  There is no
way to represent such a relocation in ELF.  It would require the relocation to
specify two different symbols, which can not be done in ELF, or it would
require a paired relocation, which is not supported for x86_64 ELF.

Comment #3 is incorrect as it refers to the special case in which the computed
difference is being put into the same section as the subtrahend symbol.  That
case does not apply here.

Actually this is on x86-linux-gnu with a newer binutils, I don't know why I
attributed it to x86_64 for some reason, which means it is not related at all
to -fasynchronous-unwind-tables.

Closing as works for me, this works for me and it worked for Honza on
2005-09-28, see PR 23396, comment #5.

Plus 2.15 errored out with your .s file.  So it looks like one of your local
patches were breaking this.

This is reproducable on gcc mainline on amd64:

This works for me with "GNU assembler 2.16.91 20051027" with the GCC mainline
on i686-linux-gnu
And with "GNU assembler 2.16" with the GCC mainline on x86_64-linux-gnu.

You should be able to reproduce this by setting BOOT_CFLAGS="-O2".  Eliminating
that allows me to successfully compile gcc-4.1 on x86_64.

The problem is that dwarf2out_switch_text_section does not get called as the
debug_hooks are set to none.

So the handling of NOTE_INSN_SWITCH_TEXT_SECTIONS is slightly wrong for this
case.  Looking more into it.

Test this again on the 4.1 branch and then will apply it there, the mainline
currently ignores BOOT_CFLAGS so I cannot test it there.

Can you file a different bug and attach the .s file?  Because I don't see this
at all.  Also can you try with a FSF release of binutils and not some hacked up
version?

I am going to apply my patch to the mainline in the next or two,  I will make
sure I also apply my follow up patch too.

And now profiledbootstrap is broken a different way on the mainline so I am not
fixing this.

I've completed a successful profiledbootstrap on amd64-linux-gnu last night. 
Is anyone else still seeing this, or is it fixed?

FWIW profiledbootstrap still fails with -march=pentium4 and fortran enabled
because of PR26449.
Last tested with 20060520.

[Bug other/22313] [4.2 Regression] profiledbootstrap is broken on the mainline

[roger at eyesopen dot com]

------- Comment #37 from roger at eyesopen dot com  2006-07-17 22:15 -------
I've now tested "make profiledbootstrap" on both mainline and the
gcc-4_1-branch,
on both x86_64-unknown-linux-gnu and i686-pc-linux-gnu, and not only does the
profiled bootstrap build fine, but the dejagnu testsuite looks identical to a
baseline "make bootstrap".

Could anyone confirm whether they're still seeing this problem?  Its likely
that Andrew Pinski's patches together with the resolution of PRs 25518 and
26449 have now resolved this issue.

[hubicka at gcc dot gnu dot org]

------- Comment #40 from hubicka at gcc dot gnu dot org  2006-08-07 08:18 -------
Roger,
the patch for advance loc seems sane solution to me (in my limited
understanding
of dwarf2). 

If I understand it right, we need the advance_loc only when crossing the
section boundary, so we ought to be able to use NOTE_INSN_SWITCH_TEXT_SECTIONS
and use the advance_loc only when tripping over it.  Only anoying thing would
be probably to get it passed out of final.c up to the offending place.

Thanks for looking into this,
Honza
