Fangrui Song	6e09722b27	[test] Use %t instead of %T to remove race conditions between config-file3.c and target-override.c ... Both tests operate on `%T/testbin`. If the two tests run concurrently, one may fail. This is likely the root cause of flaky failures reported by https://lists.llvm.org/pipermail/llvm-dev/2020-September/144781.html https://llvm.org/docs/CommandGuide/lit.html says: `%T parent directory of %t (not unique, deprecated, do not use)` Reviewed By: dblaikie Differential Revision: https://reviews.llvm.org/D87103	2020-09-03 12:28:53 -07:00
Nico Weber	ccabe93298	clang: Make tests using symlinks more consistent. ... Instead of checking if each symlink exists before removing it, remove the whole temp dir housing the symlinks before recreating it. This is a bit shorter, conceptually simpler (in that the first and consecutive test runs have more similar behavior), it's what we're already doing in almost all places where we do it, and it works if the symlink exists but is a dead link (e.g. when it points into the build dir but the build dir is renamed). No intended behavior change.	2020-04-05 12:56:41 -04:00
Serge Pavlov	3b7d381169	Put target deduced from executable name at the start of argument list ... When clang is called as 'target-clang', put deduced target option at the start of argument list so that option '--target=' specified in command line could override it. This change fixes PR34671. llvm-svn: 313760	2017-09-20 15:22:27 +00:00
