* 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

* Restore "[ThinLTO] Prevent exporting of locals used/defined in module level asm"Teresa Johnson2016-11-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This restores the rest of r286297 (part was restored in r286475). Specifically, it restores the part requiring adding a dependency from the Analysis to Object library (downstream use changed to correctly model split BitReader vs BitWriter libraries). Original description of this part of patch follows: Module level asm may also contain defs of values. We need to prevent export of any refs to local values defined in module level asm (e.g. a ref in normal IR), since that also requires renaming/promotion of the local. To do that, the summary index builder looks at all values in the module level asm string that are not marked Weak or Global, which is exactly the set of locals that are defined. A summary is created for each of these local defs and flagged as NoRename. This required adding handling to the BitcodeWriter to look at GV declarations to see if they have a summary (rather than skipping them all). Finally, added an assert to IRObjectFile::CollectAsmUndefinedRefs to ensure that an MCAsmParser is available, otherwise the module asm parse would silently fail. Initialized the asm parser in the opt tool for use in testing this fix. Fixes PR30610. llvm-svn: 286844

* [ThinLTO] Prevent exporting of locals used/defined in module level asmTeresa Johnson2016-11-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch uses the same approach added for inline asm in r285513 to similarly prevent promotion/renaming of locals used or defined in module level asm. All static global values defined in normal IR and used in module level asm should be included on either the llvm.used or llvm.compiler.used global. The former were already being flagged as NoRename in the summary, and I've simply added llvm.compiler.used values to this handling. Module level asm may also contain defs of values. We need to prevent export of any refs to local values defined in module level asm (e.g. a ref in normal IR), since that also requires renaming/promotion of the local. To do that, the summary index builder looks at all values in the module level asm string that are not marked Weak or Global, which is exactly the set of locals that are defined. A summary is created for each of these local defs and flagged as NoRename. This required adding handling to the BitcodeWriter to look at GV declarations to see if they have a summary (rather than skipping them all). Finally, added an assert to IRObjectFile::CollectAsmUndefinedRefs to ensure that an MCAsmParser is available, otherwise the module asm parse would silently fail. Initialized the asm parser in the opt tool for use in testing this fix. Fixes PR30610.

* Refactor indirect call promotion profitability analysis (NFC)Teresa Johnson2016-07-121-1/+1
| | | | | | | | | | | | | | | Summary: Refactored the profitability analysis out of the IC promotion pass and into lib/Analysis so that it can be accessed by the summary index builder in a follow-on patch to enable IC promotion in ThinLTO (D21932).

* [PM/AA] Remove the last relics of the separate IPA library from LLVM,Chandler Carruth2015-08-181-3/+0
| | | | | | | | | | | | | | | | | | | | | folding the code into the main Analysis library. There already wasn't much of a distinction between Analysis and IPA. A number of the passes in Analysis are actually IPA passes, and there doesn't seem to be any advantage to separating them. Moreover, it makes it hard to have interactions between analyses that are both local and interprocedural. In trying to make the Alias Analysis infrastructure work with the new pass manager, it becomes particularly awkward to navigate this split. I've tried to find all the places where we referenced this, but I may have missed some. I have also adjusted the C API to continue to be equivalently functional after this change.

| | | | | | | | | | | subdirectories to traverse into. - Originally I wanted to avoid this and just autoscan, but this has one key flaw in that new subdirectories can not automatically trigger a rerun of the llvm-build tool. This is particularly a pain when switching back and forth between trees where one has added a subdirectory, as the dependencies will tend to be wrong. This will also eliminates FIXME implicitly. llvm-svn: 146436
