PGI-14.10 for 32-bit targets fails in the same manner as 13.7, 13.9 and 13.10.
I believe the following inline x86 asm is correct and more robust than the existing code that pgi appears to reject: #elif defined(HWLOC_X86_32_ARCH) __asm__( "xchg %%ebx,%1\n\t" "cpuid\n\t" "xchg %%ebx,%1\n\t" : "=a" (*eax), "=S" (*ebx), "=c" (*ecx), "=d" (*edx) : "0" (*eax), "2" (*ecx)); #else -Paul On Mon, Jul 20, 2015 at 9:50 PM, Paul Hargrove <phhargr...@lbl.gov> wrote: > Pavan, > > I can confirm that I see the same with PGI-13.10. > > I have a couple systems with 14.x installed but neither with 32-bit > support. > I am downloading 32-bit support now (which I am assuming will work with > the existing license) and will report back. > > -Paul > > On Mon, Jul 20, 2015 at 9:00 PM, Balaji, Pavan <bal...@anl.gov> wrote: > >> Hello, >> >> The hwloc-1.11 build seems to fail with the pgi compiler on 32-bit >> platforms.
