[PATCH] D12711: ScanDirForExecutable on Windows fails to find executables with the "exe" extension in name

[Oleg Ranevskyy via llvm-commits]

iid_iunknown updated this revision to Diff 34360.
iid_iunknown added a comment.

sys::fs::can_execute now ignores PATHEXT similarly to ExecuteAndWait. The "exe" extension is used only.
