* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636
* ScheduleDAG: Cleanup dumping code; NFCMatthias Braun2018-09-191-6/+6
| | | | | | | | | | | | - Instead of having both `SUnit::dump(ScheduleDAG*)` and `ScheduleDAG::dumpNode(ScheduleDAG*)`, just keep the latter around. - Add `ScheduleDAG::dump()` and avoid code duplication in several places. Implement it for different ScheduleDAG variants. - Add `ScheduleDAG::dumpNodeName()` in favor of the `SUnit::print()` functions. They were only ever used for debug dumping and putting the function into ScheduleDAG is consistent with the `dumpNode()` change. llvm-svn: 342520
* MacroFusion: Fix macro fusion with ExitSU failing in top-down schedulingMatthias Braun2018-07-261-1/+11
| | | | | | | | | | | | | | | | When fusing instructions A and B, we must add all predecessors of B as predecessors of A to avoid instructions getting scheduling in between. There is a special case involving ExitSU: Every other node must be scheduled before it by design and we don't need to make this explicit in the graph, however when fusing with a different node we need to schedule every othere node before the fused node too and we need to make this explicit now: This patch adds a dependency from the fused node to all roots in the graph.

* Rename DEBUG macro to LLVM_DEBUG.Nicola Zaghen2018-05-141-11/+9
| | | | | | | | | | | | | | | | The DEBUG() macro is very generic so it might clash with other projects. The renaming was done as follows: - git grep -l 'DEBUG' | xargs sed -i 's/\bDEBUG\s\?(/LLVM_DEBUG(/g' - git diff -U0 master | ../clang/tools/clang-format/clang-format-diff.py -i -p1 -style LLVM - Manual change to APInt - Manually chage DOCS as regex doesn't match it. In the transition period the DEBUG() macro is still present and aliased to the LLVM_DEBUG() one. Differential Revision: https://reviews.llvm.org/D43624 llvm-svn: 332240
* Remove \brief commands from doxygen comments.Adrian Prantl2018-05-011-2/+2
| | | | | | | | | | | | | | | | We've been running doxygen with the autobrief option for a couple of years now. This makes the \brief markers into our comments redundant. Since they are a visual distraction and we don't want to encourage more \brief markers in new code either, this patch removes them all. Patch produced by for i in $(git grep -l '\\brief'); do perl -pi -e 's/\\brief //g' $i & done Differential Revision: https://reviews.llvm.org/D46290 llvm-svn: 331272
* [CodeGen] Improve the consistency of instruction fusion*Evandro Menezes2017-12-111-24/+55
| | | | | | | | | | | When either instruction in a fused pair has no other dependency, besides on the other instruction, make sure that other instructions do not get scheduled between them. Additionally, avoid fusing an instruction more than once along the same dependency chain. Differential revision: https://reviews.llvm.org/D36704 llvm-svn: 320420
* Target/TargetInstrInfo.h -> CodeGen/TargetInstrInfo.h to match layeringDavid Blaikie2017-11-081-1/+1
| | | | | | | | This header includes CodeGen headers, and is not, itself, included by any Target headers, so move it into CodeGen to match the layering of its implementation. llvm-svn: 317647

* Recommit rL305677: [CodeGen] Add generic MacroFusion passFlorian Hahn2017-06-191-0/+150
| | | | | | | | | | | | | Use llvm::make_unique to avoid ambiguity with MSVC. This patch adds a generic MacroFusion pass, that is used on X86 and AArch64, which both define target-specific shouldScheduleAdjacent functions. This generic pass should make it easier for other targets to implement macro fusion and I intend to add macro fusion for ARM shortly.
