Tests: check for target availability for target-specific tests. 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

// REQUIRES: arm-registered-target
Implement ARM pcs attribute. Basically it's another way of calling convention selection (AAPCS or AAPCS+VFP), similar to fastcall / stdcall / whatevercall seen on x86. In particular, all library functions should always be AAPCS regardless of floating point ABI used. llvm-svn: 129534

[CodeGenModule] Assume dso_local for -fpic -fno-semantic-interposition Summary: Clang -fpic defaults to -fno-semantic-interposition (GCC -fpic defaults to -fsemantic-interposition). Users need to specify -fsemantic-interposition to get semantic interposition behavior. Semantic interposition is currently a best-effort feature. There may still be some cases where it is not handled well.
