* [ARC] Move InstPrinter files to MCTargetDesc. NFCRichard Trieu2019-05-1110-31/+5
| | | | | | | | | For some targets, there is a circular dependency between InstPrinter and MCTargetDesc. Merging them together will fix this. For the other targets, the merging is to maintain consistency so all targets will have the same structure. llvm-svn: 360488

* [ARC] Add more load/store variants.Pete Couperus2019-03-144-52/+182
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On ARC ISA, general format of load instruction is this: LD<zz><.x><.aa><.di> a, [b,c] And general format of store is this: ST<zz><.aa><.di> c, [b,s9] Where: <zz> is data size field and can be one of <empty> (bits 00) - Word (32-bit), default behavior B (bits 01) - Byte H (bits 10) - Half-word (16-bit) <.x> is data extend mode: <empty> (bit 0) - If size is not Word(32-bit), then data is zero extended X (bit 1) - If size is not Word(32-bit), then data is sign extended <.aa> is address write-back mode: <empty> (bits 00) - no write-back .AW (bits 01) - Preincrement, base register updated pre memory transaction .AB (bits 10) - Postincrement, base register updated post memory transaction <.di> is cache bypass mode: <empty> (bit 0) - Cached memory access, default mode .DI (bit 1) - Non-cached data memory access This patch adds these load/store instruction variants to the ARC backend.

* [ARC] Better classify add/sub immediate instructions in frame lowering.Pete Couperus2019-03-141-10/+40
| | | | | | | | | | | | | | | | | | | Summary: Some operations have multiple ARC instructions that are applicable. For instance, "add r0, r0, 123" can be encoded as a "LImm" instruction with a 32-bit immediate (8-bytes), or as a signed 12-bit immediate instruction for the case where the source and destination register are the same (4-bytes). The ARC assembler will choose the shortest encoding, but we should track the correct instruction in the compiler. This patch fixes the instruction used in some cases from ARCFrameLowering.

* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-1942-168/+126
| | | | | | | | | | | | | | | | | 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

* Rename DEBUG macro to LLVM_DEBUG.Nicola Zaghen2018-05-146-72/+74
| | | | | | | | | | | | | | | | 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
* [DebugInfo] Examine all uses of isDebugValue() for debug instructions.Shiva Chen2018-05-091-1/+1
| | | | | | | | | | | | | | | | | | Because we create a new kind of debug instruction, DBG_LABEL, we need to check all passes which use isDebugValue() to check MachineInstr is debug instruction or not. When expelling debug instructions, we should expel both DBG_VALUE and DBG_LABEL. So, I create a new function, isDebugInstr(), in MachineInstr to check whether the MachineInstr is debug instruction or not. This patch has no new test case. I have run regression test and there is no difference in regression test. Differential Revision: https://reviews.llvm.org/D45342 Patch by Hsiangkai Wang. llvm-svn: 331844

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.

* [IR][CodeGen] Remove dependency on EVT from IR/Function.cpp. Move EVT to ↵Craig Topper2018-03-291-1/+1
| | | | | | | | | | | | CodeGen layer. Currently EVT is in the IR layer only because of Function.cpp needing a very small piece of the functionality of EVT::getEVTString(). The rest of EVT is used in codegen making CodeGen a better place for it. The previous code converted a Type* to EVT and then called getEVTString. This was only expected to handle the primitive types from Type*. Since there only a few primitive types, we can just print them as strings directly.

* (Re-landing) Expose a TargetMachine::getTargetTransformInfo functionSanjoy Das2017-12-222-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Re-land r321234. It had to be reverted because it broke the shared library build. The shared library build broke because there was a missing LLVMBuild dependency from lib/Passes (which calls TargetMachine::getTargetIRAnalysis) to lib/Target. As far as I can tell, this problem was always there but was somehow masked before (perhaps because TargetMachine::getTargetIRAnalysis was a virtual function). Original commit message: This makes the TargetMachine interface a bit simpler. We still need the std::function in TargetIRAnalysis to avoid having to add a dependency from Analysis to Target. See discussion: http://lists.llvm.org/pipermail/llvm-dev/2017-December/119749.html I avoided adding all of the backend owners to this review since the change is simple, but let me know if you feel differently about this.
