| | | | | | | | | | | | | | | | Summary: Removed excess new lines from documentations. As far as I can tell, it seems as though restructured text is agnostic to new lines, the use of new lines was inconsistent and had no effect on how the files were being displayed.

* AMDGPU: Add pass to lower SGPR spillsMatt Arsenault2019-07-039-33/+346
| | | | | | | | | | | | | | | This is split out from my patches to split register allocation into a separate SGPR and VGPR phase, and has some parts that aren't yet used (like maintaining LiveIntervals). This simplifies making the frame pointer register callee saved. As it is now, the code to determine callee saves needs to predict all the possible SGPR spills and how many callee saved VGPRs are needed. By handling this before PrologEpilogInserter, it's possible to just check the spill objects that already exist. Change-Id: I29e6df4034afcf949e06f8ef44206acb94696f04 llvm-svn: 365095
* [JumpThreading] Fix threading with unusual PHI nodes.Eli Friedman2019-07-035-25/+81
| | | | | | | | | | | | | | | | | | | | If the block being cloned contains a PHI node, in general, we need to clone that PHI node, even though it's trivial. If the operand of the PHI is an instruction in the block being cloned, the correct value for the operand doesn't exist until SSAUpdater constructs it. We usually don't hit this issue because we try to avoid threading across loop headers, but it's possible to hit this in some cases involving irreducible CFGs. I added a flag to allow threading across loop headers to make the testcase easier to understand. Thanks to Brian Rzycki for reducing the testcase. Fixes https://bugs.llvm.org/show_bug.cgi?id=42085.

* [Bitcode] Move Bitstream to a separate libraryFrancis Visoiu Mistrih2019-07-0357-62/+129
| | | | | | | | | | | | | | | | | | | | | | | | | This moves Bitcode/Bitstream*, Bitcode/BitCodes.h to Bitstream/. This is needed to avoid a circular dependency when using the bitstream code for parsing optimization remarks. Since Bitcode uses Core for the IR part: libLLVMRemarks -> Bitcode -> Core and Core uses libLLVMRemarks to generate remarks (see IR/RemarkStreamer.cpp): Core -> libLLVMRemarks we need to separate the Bitstream and Bitcode part. For clang-doc, it seems that it doesn't need the whole bitcode layer, so I updated the CMake to only use the bitstream part. Differential Revision: https://reviews.llvm.org/D63899 llvm-svn: 365091

* [WebAssembly] Add option to emit passive segmentsThomas Lively2019-07-0313-70/+329
| | | | | | | | | | | | | | | | | | | | | | | Summary: Adds `--passive-segments` and `--active-segments` flags to control what kind of segments are emitted. For now the default is always to emit active segments so this is not a breaking change, but in the future the default will be changed to passive segments when shared memory is requested and active segments otherwise. When passive segments are emitted, corresponding memory.init and data.drop instructions are emitted in a `__wasm_init_memory` function that is automatically called at the beginning of `__wasm_call_ctors`.

* [Bitcode] Update CHECK-DAG usage in testsJoel E. Denny2019-07-033-9/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adjusts tests not to depend on deprecated FileCheck behavior that permits overlapping matches within a block of `CHECK-DAG` directives: 1. `thinlto-function-summary-originalnames.ll`: The directive with the pattern `<COMBINED` is surely intended to match `<COMBINED ` (note the trailing space), but it instead matches `<COMBINED_GLOBALVAR_INIT_REFS`, for which there is a separate directive. With the deprecated behavior, both directives match the latter text and neither match the former text. I've adjusted the former directive so it matches only the former text. 2. `thinlto-summary-local-5.0.ll`: Two directives have identical patterns when they were clearly meant to have different patterns. 3. `upgrade-pointer-address-space.ll`: There are three identical directives but only two occurrences of the matching text. With the deprecated behavior, they always match exactly the same text, so the behavior can't have been useful. I removed one of the directives and converted the other two from `CHECK-DAG` to `CHECK`.
