* Preserve early clobber flag when using named registers in inline assembly.Daniel Sanders2015-02-041-1/+1
| | | | | | | | | | | | | | | | Summary: Named registers with the constraint "=&r" currently lose the early clobber flag and turn into "=r" when converted to LLVM-IR. This patch correctly passes it on. Reviewers: atanasyan Reviewed By: atanasyan Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D7346 llvm-svn: 228143
* Tests: check for target availability for target-specific tests.Jim Grosbach2012-07-091-0/+1
| | | | | | | | Lots of tests are using an explicit target triple w/o first checking that the target is actually available. Add a REQUIRES clause to a bunch of them. This should hopefully unbreak bots which don't configure w/ all targets enabled. llvm-svn: 159949
