2014-03-31InstrProf: lit.cfg magic for running tests from sourceDuncan P. N. Exon Smith
Implement magic in compiler-rt to enable llvm-lit to be invoked on the source tree in lib/profile. This relies on a paired commit in the llvm tree that exposes a new built-in parameter. <rdar://problem/16458307> git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@205263 91177308-0d34-0410-b5e6-96231b3b80d8
2014-03-31InstrProf: Add simple compiler-rt testDuncan P. N. Exon Smith
Add the test infrastructure for testing lib/profile and a single test. This initial commit only enables the tests on Darwin, but they'll be enabled on Linux soon after. <rdar://problem/16458307> git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@205256 91177308-0d34-0410-b5e6-96231b3b80d8
