[OpenMP][OMPT] fix reduction test for 32-bit x86

2020-02-05T14:28:24+00:00

Fixes [[ https://bugs.llvm.org/show_bug.cgi?id=44733 | TEST 'libomp :: ompt/synchronization/reduction/tree_reduce.c' FAILED on 32-bit x86 ]] For 32-bit we need at least 3 variables to avoid atomic reduction to be choosen by runtime function `__kmp_determine_reduction_method`. This patch adds reduction variables to the testcase.

[OpenMP] Remove -Wl,-fini=__kmp_internal_end_fini

2019-11-18T23:54:58+00:00

Summary: The termination function duplicated the functionality of the __attribute((destructor))-annotated function __kmp_internal_end_fini, and we have no indication that this doesn't work. The function might cause issues with link-time optimization turned on: until very recently, none of the usual linkers was reporting functions named in -Wl,-fini as used to the LTO plugin, so it might be dropped. If the function is dropped, -Wl,-fini=__kmp_internal_end_fini doesn't do what we want: with ld.bfd and lld it drops the FINI attribute from .dynamic and with gold we get FINI = 0x0, which leads to a crash on cleanup. This can be reproduced by building with -DLLVM_ENABLE_PROJECTS="clang;openmp" \ -DLLVM_ENABLE_LTO=Thin \ -DLLVM_USE_LINKER=gold The issue in lld has been fixed in f95273f75aa, but gold remains without fix so far.
