Hi All,
The 'make check -j' command fails occasionally for the testcase
remove-global-vars.ll,
which is added in a recent commit.
We suspect this is because of a race condition occurring due to the
simultaneous read of the file reduce.ll by FileCheck (when make check -j is
used), which is generated by llvm-reduce. The file reduce.ll is both
consumed by the testcases remove-global-vars.ll and remove-funcs.ll, which when
executed in parallel, one of them might read the wrong reduce.ll generated
by the other.
Could someone confirm this indeed is the case?
