[PATCH] D154087: Upstream Cygwin Clang patches

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

This really needs to be submitted as three separate patches: one for for the clang/lib/Basic changes, one for the X86TargetMachine changes, and one for the clang driver.  And the changes need to update the corresponding regression tests (in clang/test/ and llvm/test/) to verify for cygwin-specific behavior.  (Let me know if you can't find the relevant regression tests.)

Is clang crashing?  Usually when clang crashes it prints some indication of that to stderr, but I guess the crash handler might be broken on cygwin.  Have you tried attaching a debugger?
