--- Comment #1 from Andrew Macleod <amacleod at redhat dot com> 2011-11-21 19:21:30 UTC ---
32 bit targets don't usually support 128 bit atomic operations natively, and
leave calls to be resolved by an external atomic library.   There was some
issue with X32 support where 32 bit could support it under some circumstances.

Now gcc/testsuite/lib/target-supports.exp defines the testsuite check for
whether 128 bit is supported as:

proc check_effective_target_sync_int_128 { } {
    if { ([istarget x86_64-*-*] || [istarget i?86-*-*])
         && ![is-effective-target ia32] } {
        return 1
    } else {
        return 0
    }
}

I presume if 32 bit solaris isn't supporting 128 bit operations then this needs
to be tweaked...

The quoted test ought to have worked for i386-solaris.
If one of those predicates is wrong (e.g. is-effective-target ia32)
then there are other tests in the testsuite that are going to be
failing unnecessarily.

There's nothing Solaris-specific here, as I'm seeing the same issue on a
bi-arch i386-apple-darwin9.8.0 compiler for the 64-bit multilib.  It
seems the 32-bit compiler doesn't generate the 128-bit atomic insns when
generating 64-bit code.

--- Comment #4 from Andrew Macleod <amacleod at redhat dot com> 2011-11-22 16:07:52 UTC ---
I built a compiler in my linux box with a target of i386-apple-darwin.

during expanding an atomic_exchange it fails the call to
can_compare_and_swap_p(TImode, true).

It returns CODE_FOR_nothing for both cases:

icode = direct_optab_handler (atomic_compare_and_swap_optab, mode);
if (icode != CODE_FOR_nothing)
  return true;

icode = optab_handler (sync_compare_and_swap_optab, mode);
if (icode != CODE_FOR_nothing)
  return true;

so something in the config/i386/sync.md file must be wrong for a 32 bit
compiler which specifies -m64.  It does not set up the optab table for a TI
mode compare_and_swap.

-mcx16 ?

It is a testsuite problem:

/* { dg-options "-mcx16" { target { x86_64-*-* } } } */

Something is missing there ... ;)

yes, presuming that it works, which I think it will, that will have to be
applied to all the gcc.dg/atomic*-5.c files, as well as the
gcc.dg/simulate-thread/atomic-*-int128.c files.

Can you try with increased timeout value?

In testsuite/lib/gcc-simulate-thread.exp find following line:

    # Set timeout to 10 seconds due to huge amount of generated log.
    remote_expect target 10 {

and increase 10.

If this fails, you should check if generated executable runs OK outside of the
debugger.

The actual binaries for atomic-load-int128.c  at -O1 and higher run fine on
x86_64-apple-darwin64 at -m64. However they take around 16 seconds to execute
on a...

      Model Name: Mac Pro
      Model Identifier: MacPro3,1
      Processor Name: Quad-Core Intel Xeon
      Processor Speed: 2.8 GHz
      Number of Processors: 2
      Total Number of Cores: 8
      L2 Cache (per Processor): 12 MB
      Memory: 12 GB
      Bus Speed: 1.6 GHz

Increasing the timeout to 20 seconds allows all of the
gcc.dg/simulate-thread/atomic-load-int128.c tests to pass.

GCC 4.7.0 is being released, adjusting target milestone.

Is this not resolved in 4.7?  I thought we had changed the timeouts back to
normal and added other mechanisms to avoid large infinite loops

Indeed, so closing.
