2016-04-06	[gold] Save bitcode for module partitions (save-temps + split codegen).	Evgeniy Stepanov	1	-9/+17
	llvm-svn: 265583
2016-03-04	Change split code gen to use ThreadPool	Teresa Johnson	1	-32/+40
	Part of D15390. llvm-svn: 262719
2016-01-18	Add to the split module utility an SCC based method which allows not to ↵	Sergei Larin	1	-2/+3
	globalize any local variables. Summary: Currently llvm::SplitModule as the first step globalizes all local objects, which might not be desirable in some scenarios. This change adds a new flag to llvm::SplitModule that uses SCC approach to search for a balanced partition without the need to externalize symbols. Such partition might not be possible or fully balanced for a given number of partitions, and is a function of the module properties (global/local dependencies within the module).

2015-11-19	[LTO] Add option to emit assembly from LTOCodeGenerator	Tobias Edler von Koch	1	-7/+8
	This adds a new API, LTOCodeGenerator::setFileType, to choose the output file format for LTO CodeGen. A corresponding change to use this new API from llvm-lto and a test case is coming in a separate commit. Differential Revision: http://reviews.llvm.org/D14554 llvm-svn: 253622
2015-08-31	Support: Support LLVM_ENABLE_THREADS=0 in llvm/Support/thread.h.	Peter Collingbourne	1	-2/+2
	Specifically, the header now provides llvm::thread, which is either a typedef of std::thread or a replacement that calls the function synchronously depending on the value of LLVM_ENABLE_THREADS. llvm-svn: 246402
2015-08-27	CodeGen: Introduce splitCodeGen and teach LTOCodeGenerator to use it.	Peter Collingbourne	1	-0/+95
	llvm::splitCodeGen is a function that implements the core of parallel LTO code generation. It uses llvm::SplitModule to split the module into linkable partitions and spawning one code generation thread per partition. The function produces multiple object files which can be linked in the usual way. This has been threaded through to LTOCodeGenerator (and llvm-lto for testing purposes). Separate patches will add parallel LTO support to the gold plugin and lld. Differential Revision: http://reviews.llvm.org/D12260 llvm-svn: 246236
