[gmx-users] gmx_simd_check_and_reset_overflow undefined for sparc64 hpc ace

[Matthew Harrigan]

Hi all, 
I'm having trouble compiling gromacs (from git master) for sparc64 SIMD. It fails with 

"gromacs/src/gromacs/mdlib/tpi.cpp", line 470: error: identifier "gmx_simd_check_and_reset_overflow" is undefined 
gmx_simd_check_and_reset_overflow(); 

It looks like this should be defined in simd/impl_sparc64_hpc_ace.h but isn't. 

Has anyone run into this? I noticed that for some of the SIMD implementations (intel qpx, vmx, vsx), that function just returns 0. Is that appropriate here? 

Thanks, 
Matt
