CodeGen: Fix handling of C++11 lambdas in profiling Until now we were generating duplicate counters for lambdas: one set in the function where the lambda was declared and another for the lambda itself. Instead, we should skip over the bodies of lambdas in their containing contexts. llvm-svn: 206081

// Tests for instrumentation of C++11 lambdas
// RUN: %clang_cc1 -x c++ %s -triple %itanium_abi_triple -main-file-name cxx-lambda.cpp -std=c++11 -o - -emit-llvm -fprofile-instr-generate > %tgen
// RUN: FileCheck --input-file=%tgen -check-prefix=PGOGEN %s
// RUN: FileCheck --input-file=%tgen -check-prefix=LMBGEN %s
test: Use llvm-profdata merge in Profile tests In preparation for using a binary format for instrumentation based profiling, explicitly treat the test inputs as text and transform them before running. This will allow us to leave the checked in files in human readable format once the instrumentation format is binary. No functional change. llvm-svn: 206509

Account for calling convention specifiers in function definitions in IR test cases Several tests wouldn't pass when executed on an armv7a_pc_linux triple due to the non-default arm_aapcs calling convention produced on the function definitions in the IR output. Account for this with the application of a little regex. Patch by Ying Yi. llvm-svn: 240971
