As described in
[testsuite] Provide TLS access model testcases
http://gcc.gnu.org/ml/gcc-patches/2011-05/msg01601.html
both the 32 and 64-bit TLS GD and LD execution tests fail on Solaris 2
with Sun ld unless you have a very recent Solaris 11 version (snv_164).
This happens because the code sequences emitted by GCC don't match those
expected by Sun ld:
32-bit x86: Thread-Local Variable Access
http://download.oracle.com/docs/cd/E19963-01/html/819-0690/chapter8-20.html#gentextid-20367
For GD, one needs to use call x@tlsgdplt here, but call ___tls_get_addr@plt
works, too.
For LD, one really needs call x@tlsldmplt.
The corresponding R_386_TLS_GD_PLT and R_386_TLS_LDM_PLT relocations are
not yet handled by binutils.
x64: Thread-Local Variable Access
http://download.oracle.com/docs/cd/E19963-01/html/819-0690/chapter8-20.html#chapter8-60
For both GD and LD, one needs to use call __tls_get_addr@plt.
The following patch handles this:
* It autoconfigures support for the @tlsgdplt and @tlsldmplt
relocations: Sun as supports them, while gas doesn't yet. I've got a
patch in the works to fix this: while the gas part is easy, I have
serious problems getting the ld side to work properly. Unfortunately,
I doubt the binutils maintainers will accept such partial support for
the relocs.
* I'm using a new 'p' code to control the printing of @plt. 'P' doesn't
work since this is needed in both PIC and non-PIC code.
Bootstrapped without regressions on i386-pc-solaris2.10.
Ok for mainline?

Since handling of "p" is not conditional (that is, controlled by some
compile flag), it is IMO better to just output correct assembly from
the insn pattern itself. You will also output lower-case "@plt" which
is IIRC preferred by Sun assebler.
Something like attached (untested) patch.

I've never seen such an issue.

Unfortunately, the Solaris 10/x86 bootstrap fails in the stage1 libgomp:
/vol/gcc/src/hg/trunk/solaris/libgomp/single.c: In function 'GOMP_single_start':
/vol/gcc/src/hg/trunk/solaris/libgomp/single.c:55:1: internal compiler error: ou

Hm, there is no %P1 present, so I don't think this should be an issue.

OK, it is your call... please change @plt to @PLT if desired.

I'll keep it at @plt for consistency with the rest.

I think it makes sense to try to provide reasonable coverage of TLS tests
with all of -fPIC, -fpic, -fPIE and -fpie.

Bah. %P has a special handling that removes (%rip). Are you sure Sun
assembler requests @plt in PIC and non-PIC cases? Can we solve this
with TARGET_SUN_TLS somehow?
Thanks,
Uros.

Pretty much so: my first attempts to resolve this consisted in taking
the regular gcc assembler output and mangling it until it worked with ld.
> with TARGET_SUN_TLS somehow?
We could certainly duplicate (some of) the logic that %P already uses,
but I though it easier to just introduce a straightforward variant (%p)
instead. It's not pretty, but it worked.

OK then... can you propose a new patch, please, changing as little of
generic code as possible?

I'll try, but somewhat fear that I will arive again at what I had
initially. Will probably have to wait for the weekend.

Please find attached the patch that introduces %p to output only the
raw symbol name. @plt is added "manually", since it doesn't really
follow -fpic flag.

Thanks, that almost did it:
* HAVE_AS_IX86_{TLSGDPLT, TLSLDMPLT} are always defined as 0/1, so we
need if, not #ifdef.
* The @tlsldmplt TARGET_SUN_TLS test was inverted.
The patch below has just been bootstrapped on i386-pc-solaris2.11 with
both Sun as (which supports both relocs) and gas (which supports none).
With Sun as, all run-{gd, ld}.c failures are gone, with GNU as, the
32-bit run-ld.c failures remain, as expected. I'll next try to get
@tls{gd, ldm}plt support into gas.
Ok for mainline now?

There is no need to always define it. Please simplify your

Uh, yes... I have used it during testing and forgot to remove inverted check.

Please change the check in configure.ac to conditionally define

The patch is OK with this change.

Here's what I've checked in after retesting as described before. I've
