[Openmp-dev] Verbose outlining name

[Ye Luo via Openmp-dev]

Hi,
I noticed that clang outlines OpenMP regions without giving verbose
function names.
As shown below, it is almost impossible to tell where
"__omp_outlined__5_wrapper" is from when compiling a big program.However, I
need to investigate these regions and reduce register spill which is
performance critical.

ptxas info    : Function properties for
__omp_offloading_33_3c57fa9__ZN11qmcplusplus12SplineC2ROMPIdfE17evaluateDetRatiosINS_6VectorIfSaIfELj0EEEfEEvRKNS_18VirtualParticleSetERT_RKS9_RSt6vectorIT0_SaISE_EE_l571
    32 bytes stack frame, 0 bytes spill stores, 0 bytes spill loads
ptxas info    : Function properties for __omp_outlined__5_wrapper
    224 bytes stack frame, 136 bytes spill stores, 136 bytes spill loads
ptxas info    : Function properties for
_ZN7spline228computeLocationAndFractionalIdEEvPKN11qmcplusplus14bspline_traitsIT_Lj3EE10SplineTypeES3_S3_S3_RiS8_S8_PS3_S9_S9_
    272 bytes stack frame, 236 bytes spill stores, 236 bytes spill loads
ptxas info    : Function properties for __omp_outlined__1_wrapper
    368 bytes stack frame, 340 bytes spill stores, 340 bytes spill loads

A composite name __omp_outlined_SOURCE_FUNCTION_NAME is way more useful.
Could someone fix this or point me where to fix this in the clang source.

Best,
Ye
