Alexey Bataev 1d7f0faf93 [OPENMP] Propagate alignment from original variables to the private copies.
Currently private copies of captured variables have default alignment. Patch makes private variables to have same alignment as original variables.

Alexey Bataev 2377fe95c6 [OPENMP] Outlined function for parallel and other regions with list of captured variables.
Currently all variables used in OpenMP regions are captured into a record and passed to outlined functions in this record. It may result in some poor performance because of too complex analysis later in optimization passes. Patch makes to emit outlined functions for parallel-based regions with a list of captured variables. It reduces code for 2*n GEPs, stores and loads at least.
Codegen for task-based regions remains unchanged because runtime requires that all captured variables are passed in captured record.

Alexey Bataev b44fdfc7b2 [OPENMP] Drop type qualifiers from private variables.
If the variable is marked as private in OpenMP construct, the reference to this variable should not keep type qualifiers for the original variable. Private copy is not volatile or constant, so we can use unqualified type for private copy.

Adrian Prantl e50371b948 Wrap clang modules and pch files in an object file container.
This patch adds ObjectFilePCHContainerOperations uses the LLVM backend
to put the contents of a PCH into a __clangast section inside a COFF, ELF,
or Mach-O object file container.

This is done to facilitate module debugging by makeing it possible to
store the debug info for the types defined by a module alongside the AST.

David Blaikie ea3e51d73f 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.

Alexey Bataev aac108a324 [OPENMP] Do not emit references to original variables in 'private' clause.
Currently if the variable is captured in captured region, capture record for this region stores reference to this variable for future use. But we don't need to provide the reference to the original variable if it was explicitly marked as private in the 'private' clause of the OpenMP construct, this variable is replaced by private copy.

Alexey Bataev db39021cee [OPENMP] -fopenmp enables OpenMP support (fix for http://llvm.org/PR23492)
-fopenmp turns on OpenMP support and links libiomp5 as OpenMP library. Also there is -fopenmp={libiomp5|libgomp} option that allows to override effect of -fopenmp and link libgomp library (if -fopenmp=libgomp is specified).

Alexey Bataev 69c62a9bdb [OPENMP] Codegen for 'firstprivate' clause in 'for' directive.
Adds proper codegen for 'firstprivate' clause in for directive. Initially codegen for 'firstprivate' clause was implemented for 'parallel' directive only.
Also this patch emits sync point only after initialization of firstprivate variables, not all private variables. This sync point is not required for privates, lastprivates etc., only for initialization of firstprivate variables.

Reid Kleckner d2f6c726e7 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.

Adrian Prantl 8bf7af3de8 Wrap clang module files in a Mach-O, ELF, or COFF container.
This is a necessary prerequisite for debugging with modules.
The .pcm files become containers that hold the serialized AST which allows
us to store debug information in the module file that can be shared by all
object files that were built importing the module.

This reapplies r230044 with a fixed configure+make build and updated
dependencies and testcase requirements. Over the last iteration this
version adds
- missing target requirements for testcases that specify an x86 triple,
- a missing clangCodeGen.a dependency to libClang.a in the make build.

Alexey Bataev f841bd9fcd [OPENMP] Bugfix for processing of global variables in OpenMP regions.
Currently, if global variable is marked as a private OpenMP variable, the compiler crashes in debug version or generates incorrect code in release version. It happens because in the OpenMP region the original global variable is used instead of the generated private copy. It happens because currently globals variables are not captured in the OpenMP region.
This patch adds capturing of global variables iff private copy of the global variable must be used in the OpenMP region.

Alexey Bataev 8f7c1b0b9d [OPENMP] Codegen for 'omp barrier' directive.
Adds generation of call to "i32 kmpc_cancel_barrier(ident_t *, i32)" libcall for explicitly specified barriers (OMP_IDENT_BARRIER_EXPL flag is added to "flags" field of "ident_t" structure).
Also this patch replaces all calls to "kmpc_barrier" function by calls of "__kmpc_cancel_barrier" function which provides additional functionality for OpenMP 4.0.
Also, library specific enum OpenMPLocationFlags moved to private section of CGOpenMPRuntime class to make it more independent from library implementation.

Alexey Bataev 03b340a3a5 [OPENMP] Codegen for 'private' clause in 'parallel' directive.
This patch generates some helper variables which used as a private copies of the corresponding original variables inside an OpenMP 'parallel' directive. These generated variables are initialized by default (with the default constructor, if any). In outlined function references to original variables are replaced by the references to these private helper variables. At the end of the initialization of the private variables and implicit barier is set by calling __kmpc_barrier(...) runtime function to be sure that all threads were initialized using original values of the variables.
