Log:
Revert r310291, r310300 and r310332 because of test failure on Darwin
The commit r310291 introduced the failure. r310332 was a test fix commit and
r310300 was a followup commit. I reverted these two to avoid merge conflicts
when reverting.
The 'openmp-offload.c' test is failing on Darwin because the following
run lines:
// RUN: touch %t1.o
// RUN: touch %t2.o
// RUN: %clang -### -no-canonical-prefixes -fopenmp=libomp -fopenmp-targets=nvptx64-nvidia-cuda -save-temps -no-canonical-prefixes %t1.o %t2.o 2>&1 \
// RUN: | FileCheck -check-prefix=CHK-TWOCUBIN %s
trigger the following assertion:
Driver.cpp:3418:
assert(CachedResults.find(ActionTC) != CachedResults.end() &&
"Result does not exist??");
