* 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
* Rename DEBUG macro to LLVM_DEBUG.Nicola Zaghen2018-05-141-2/+4
| | | | | | | | | | | | | | | | 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

* Revert "[ADT] Make Twine's copy constructor private."Zachary Turner2017-10-111-2/+2
| | | | | | | | | | This reverts commit 4e4ee1c507e2707bb3c208e1e1b6551c3015cbf5. This is failing due to some code that isn't built on MSVC so I didn't catch. Not immediately obvious how to fix this at first glance, so I'm reverting for now. llvm-svn: 315536
* [ADT] Make Twine's copy constructor private.Zachary Turner2017-10-111-2/+2
| | | | | | | | | | | | | | | | | There's a lot of misuse of Twine scattered around LLVM. This ranges in severity from benign (returning a Twine from a function by value that is just a string literal) to pretty sketchy (storing a Twine by value in a class). While there are some uses for copying Twines, most of the very compelling ones are confined to the Twine class implementation itself, and other uses are either dubious or easily worked around. This patch makes Twine's copy constructor private, and fixes up all callsites. Differential Revision: https://reviews.llvm.org/D38767 llvm-svn: 315530
* TableGen support for parameterized register class informationKrzysztof Parzyszek2017-09-141-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | This replaces TableGen's type inference to operate on parameterized types instead of MVTs, and as a consequence, some interfaces have changed: - Uses of MVTs are replaced by ValueTypeByHwMode. - EEVT::TypeSet is replaced by TypeSetByHwMode. This affects the way that types and type sets are printed, and the tests relying on that have been updated. There are certain users of the inferred types outside of TableGen itself, namely FastISel and GlobalISel. For those users, the way that the types are accessed have changed. For typical scenarios, these replacements can be used: - TreePatternNode::getType(ResNo) -> getSimpleType(ResNo) - TreePatternNode::hasTypeSet(ResNo) -> hasConcreteType(ResNo) - TypeSet::isConcrete -> TypeSetByHwMode::isValueTypeByHwMode(false) For more information, please refer to the review page.

* [TableGen] Fix some mismatches in the use of Namespace fields versus Target ↵Craig Topper2017-07-071-1/+1
| | | | | | | | | | | | name in some of our emitters. Some of our emitters were using the name of the Target to reference things that were created by others emitters using Namespace. Apparently all targets have the same Target name as their instruction and register Namespace field? Someone on IRC had a target that didn't do this and was getting build errors. This patch is a necessary, but maybe not sufficient fix. llvm-svn: 307358

* TableGen: Fix infinite recursion in RegisterBankEmitterTom Stellard2017-01-301-3/+11
| | | | | | | | | | | | | | | | Summary: AMDGPU has two register classes with the same set of registers, and this was causing this tablegen backend would get stuck in infinite recursion.

* Re-commit: [globalisel] Tablegen-erate current Register Bank InformationDaniel Sanders2017-01-181-0/+309
| | | | | | | | | | | | | | | | | | | | | | | Summary: Adds a RegisterBank tablegen class that can be used to declare the register banks and an associated tablegen pass to generate the necessary code. Changes since last commit: The new tablegen pass is now correctly guarded by LLVM_BUILD_GLOBAL_ISEL and this should fix the buildbots however it may not be the whole fix. The previous buildbot failures suggest there may be a memory bug lurking that I'm unable to reproduce (including when using asan) or spot in the source. If they re-occur on this commit then I'll need assistance from the bot owners to track it down.
