Is this a known bug or do we need to report it to Sun?
If known, is there a patch we can recommend in the Solaris-specific
installation docs?

Since the Sun toolchain doesn't use the assembler by default, it is very
likely unknown to them.

I think the first step is to report it to sun so they track it and hopefully
one day fix their toolchain. Does anyone have a support contract who can file
a report?

As a workaround, gcc could check for this in configure and if it detects the
bug,
override TARGET_ASM_SELECT_SECTION such that on Solaris with this bug
detected it would:
section *
solaris_elf_select_section (tree decl, int reloc,
unsigned HOST_WIDE_INT align)
{
#if HAVE_AS_TBSS_BUG
if (TREE_CODE (decl) == VAR_DECL && DECL_THREAD_LOCAL_P (decl)
&& categorize_decl_for_section (decl, reloc, flag_pic) == SECCAT_TBSS)
/* Solaris AS doesn't handle .tbss variables properly. Use .tdata section.
*/
return get_named_section (DECL_P (decl) ? decl : NULL, ".tdata", reloc);
#endif
return default_elf_select_section_1 (decl, reloc, align, flag_pic);
}
and similarly with TARGET_ASM_UNIQUE_SECTION.

gcc44-pr29987.patch
Anyway, the following patch fixes this in a cross from x86_64-linux to
sparc*-sun-solaris10. Can somebody please bootstrap/regtest it?
Does i?86-sun-solaris* as have the same bug or not?

I'll have to check this. Currently, one cannot use Sun as for x86_64, so
the default config will use gas instead. I'll try the non-multilib config
and see if it is affected as well.

Bootstrap on Solaris 10/x86 with Sun as already breaks when building the
stage1 libgcc now:
Assembler: libgcov.c
"/var/tmp//ccRimvP4.s", line 116 : Syntax error
Near line: " repnz scasb"
and many more. I have no idea what as complains about: a quick strings on
the binary reveals that it seems to support the instruction, and the x86
Assembly Language Reference Manual at
http://docs.sun.com/app/docs/doc/817-5477/enmzx?a=view
suggests likewise in the `String Instructions' table (table 3-8).

Bootstrap with the patch completed (unlike the situation without, where
libgomp.so failed to link). Testresults are still hampered by the
following gld 2.19 warning
/vol/gcc/lib/gld-2.19: warning: section `.bss' type changed to PROGBITS
which I'll investigate. There's something in
http://sourceware.org/bugzilla/show_bug.cgi?id=7027
(Comments #18 - 24). It seems like Sun as doesn't mark .bss.* sections as
NOBITS. Probably another bug to take up with Sun.

Apart from the problems reported in Comment #8, Sun as heavily chokes on
the tls conftest_s in gcc/configure.ac:
* as is invoked with the gas-only --fatal-warnings, which lets Sun as
choke.
* The test itself uses the gas .section syntax that Sun as doesn't
understand.
To properly handle this, one would need to have two sections as in the
sparc-*-solaris2* case. Right now, it doesn't make much sense to pursue
this.

Bootstrapped/regtested with GNU as for the sake of completeness.
