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
[PGO] cc1 option name change for profile instrumentation This patch changes cc1 option -fprofile-instr-generate to an enum option -fprofile-instrument={clang|none}. It also changes cc1 options -fprofile-instr-generate= to -fprofile-instrument-path=. The driver level option -fprofile-instr-generate and -fprofile-instr-generate= remain intact. This change will pave the way to integrate new PGO instrumentation in IR level. Review: http://reviews.llvm.org/D16730 llvm-svn: 259811

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

[PGO] Change profile use cc1 option to handle IR level profiles This patch changes cc1 option for PGO profile use from -fprofile-instr-use=<path> to -fprofile-instrument-use-path=<path>. -fprofile-instr-use=<path> is now a driver only option. In addition to decouple the cc1 option from the driver level option, this patch also enables IR level profile use. cc1 option handling now reads the profile header and sets CodeGenOpt ProfileUse (valid values are {None, Clang, LLVM} -- this is a common enum for -fprofile-instrument={}, for the profile instrumentation), and invoke the pipeline to enable the respective PGO use pass.

[Coverage] Add support for Branch Coverage in LLVM Source-Based Code Coverage This is an enhancement to LLVM Source-Based Code Coverage in clang to track how many times individual branch-generating conditions are taken (evaluate to TRUE) and not taken (evaluate to FALSE). Individual conditions may comprise larger boolean expressions using boolean logical operators. This functionality is very similar to what is supported by GCOV except that it is very closely anchored to the ASTs. Differential Revision: https://reviews.llvm.org/D84467

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
