* Sort the remaining #include lines in include/... and lib/....Chandler Carruth2017-06-061-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | I did this a long time ago with a janky python script, but now clang-format has built-in support for this. I fed clang-format every line with a #include and let it re-sort things according to the precise LLVM rules for include ordering baked into clang-format these days. I've reverted a number of files where the results of sorting includes isn't healthy. Either places where we have legacy code relying on particular include ordering (where possible, I'll fix these separately) or where we have particular formatting around #include lines that I didn't want to disturb in this patch. This patch is *entirely* mechanical. If you get merge conflicts or anything, just ignore the changes in this patch and run clang-format over your #include lines in the files. Sorry for any noise here, but it is important to keep these things stable. I was seeing an increasing number of patches with irrelevant re-ordering of #include lines because clang-format was used. This patch at least isolates that churn, makes it easy to skip when resolving conflicts, and gets us to a clean baseline (again). llvm-svn: 304787
* [IR] Make getParamAttributes take argument numbers, not ArgNo+1Reid Kleckner2017-04-131-3/+3
| | | | | | | | | | | | Add hasParamAttribute() and use it instead of hasAttribute(ArgNo+1, Kind) everywhere. The fact that the AttributeList index for an argument is ArgNo+1 should be a hidden implementation detail. NFC llvm-svn: 300272
* [AMDGPU] Temporarily change constant address space from 4 to 2Yaxun Liu2017-04-061-5/+5
| | | | | | | | | | Our final address space mapping is to let constant address space to be 4 to match nvptx. However for now we will make it 2 to avoid unnecessary work in FE/BE/devlib about intrinsics returning constant pointers. Differential Revision: https://reviews.llvm.org/D31770 llvm-svn: 299690

* [AMDGPU] Get address space mapping by target triple environmentYaxun Liu2017-03-271-17/+50
| | | | | | | | | | | | | | | | | | As we introduced target triple environment amdgiz and amdgizcl, the address space values are no longer enums. We have to decide the value by target triple. The basic idea is to use struct AMDGPUAS to represent address space values. For address space values which are not depend on target triple, use static const members, so that they don't occupy extra memory space and is equivalent to a compile time constant. Since the struct is lightweight and cheap, it can be created on the fly at the point of usage. Or it can be added as member to a pass and created at the beginning of the run* function.

* [AMDGPU] Add address space based alias analysis passStanislav Mekhanoshin2017-03-171-0/+117
This is direct port of HSAILAliasAnalysis pass, just cleaned for style and renamed. Differential Revision: https://reviews.llvm.org/D31103 llvm-svn: 298172
