* 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
* [Transforms] Prefer static and avoid namespaces, NFCReid Kleckner2018-11-191-10/+6
| | | | | | | | | | | | | Put 'static' on three functions in an anonymous namespace as per our coding style. Remove the 'namespace llvm {}' around the .cpp file and explicitly declare the free function 'llvm::optimizeGlobalCtorsList' in 'llvm::'. I prefer this style for free functions because the compiler will error out if the .h and .cpp files don't agree on the function name or prototype. llvm-svn: 347269
* Rename DEBUG macro to LLVM_DEBUG.Nicola Zaghen2018-05-141-1/+1
| | | | | | | | | | | | | | | | 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

* TransformUtils: Remove implicit ilist iterator conversions, NFCDuncan P. N. Exon Smith2015-10-131-1/+1
| | | | | | | | | | | Continuing the work from last week to remove implicit ilist iterator conversions. First related commit was probably r249767, with some more motivation in r249925. This edition gets LLVMTransformUtils compiling without the implicit conversions. No functional change intended. llvm-svn: 250142
* Revert r240137 (Fixed/added namespace ending comments using clang-tidy. NFC)Alexander Kornienko2015-06-231-1/+1

* GlobalOpt: Preserve comdats of unoptimized initializersReid Kleckner2014-09-231-45/+26
| | | | | | | | | | | | | Rather than slurping in and splatting out the whole ctor list, preserve the existing array entries without trying to understand them. Only remove the entries that we know we can optimize away. This way we don't need to wire through priority and comdats or anything else we might add. Fixes a linker issue where the .init_array or .ctors entry would point to discarded initialization code if the comdat group from the TU with the faulty global_ctors entry was dropped. llvm-svn: 218337
* Add comdat key field to llvm.global_ctors and llvm.global_dtorsReid Kleckner2014-05-161-12/+14
| | | | | | | | | | | | | | This allows us to put dynamic initializers for weak data into the same comdat group as the data being initialized. This is necessary for MSVC ABI compatibility. Once we have comdats for guard variables, we can use the combination to help GlobalOpt fire more often for weak data with guarded initialization on other platforms.

* Teach GlobalDCE how to remove empty global_ctor entries.Nico Weber2014-05-021-0/+181
This moves most of GlobalOpt's constructor optimization code out of GlobalOpt into Transforms/Utils/CDtorUtils.{h,cpp}. The public interface is a single function OptimizeGlobalCtorsList() that takes a predicate returning which constructors to remove. GlobalOpt calls this with a function that statically evaluates all constructors, just like it did before. This part of the change is behavior-preserving. Also add a call to this from GlobalDCE with a filter that removes global constructors that contain a "ret" instruction and nothing else – this fixes PR19590. llvm-svn: 207856
