X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=5e1452c856a8bcf39ab7a67a5af946c8162f942d;p=oota-llvm.git

Add an -append-exit-code option to bugpoint. This will cause bugpoint to
append "exit <retcode>" to the end of the output file. This is used by
the nightly tester to make bugpoint match the output generated by the
RunSafely.sh script so it doesn't find false positives.
