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

InstrProf: Make profile variables private to reduce binary size overhead When we instrument a program for profiling, we copy the linkage of an instrumented function so that our datastructures merge in the same way as the function. This avoids redundant copies for things like linkonce, but ends up emitting names we never need to reference for normal and internal symbols. Promoting internal and external linkage to private for these variables reduces the size overhead of profiling drastically. llvm-svn: 232799

Re-land "MS ABI: lambda call operators are instance methods and should use thiscall" Update the test cases to pass when lambda call operators use thiscall. Update the lambda-to-block conversion operator to use the default free function calling convention instead of the call operator's convention. This reverts commit r233082 and re-instates r233023. llvm-svn: 233835
