InstrProf: Remove LTO dependency from test The -flto flag relies on linker features that are not available on all platforms. <rdar://problem/16458307> llvm-svn: 205318

// RUN: %clang_profgen -o %t -O3 %s
Allow any test to be executed via a %run command. Configure %run with COMPILER_RT_EMULATOR: $ cmake -DCOMPILER_RT_EMULATOR="qemu-arm -L $SYSROOT" llvm-svn: 207707

// RUN: env LLVM_PROFILE_FILE=%t.profraw %run %t
InstrProf: Add simple compiler-rt test 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> llvm-svn: 205256

profile: Avoid name collisions between instrumentation and runtime The naming scheme we're using for counters in profile data shares a prefix with some fixed names we use for the runtime, notably __llvm_profile_data_begin and _end. Embarrassingly, this means a function called begin() can't be instrumented. This modifies the runtime names so as not to collide with the instrumentation. llvm-svn: 217166

Update lib/profile tests for metadata assembly change Running the upgrade script from PR21532. Hopefully this will unstick compiler-rt bots [1] after r224257. [1]: http://lab.llvm.org:8080/green/job/clang-stage1-cmake-RA_check/181/ llvm-svn: 224276
