* [opaque pointer types] Cleanup CGBuilder's Create*GEP.James Y Knight2019-02-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Some of these functions take some extraneous arguments, e.g. EltSize, Offset, which are computable from the Type and DataLayout. Add some asserts to ensure that the computed values are consistent with the passed-in values, in preparation for eliminating the extraneous arguments. This also asserts that the Type is an Array for the calls named "Array" and a Struct for the calls named "Struct". Then, correct a couple of errors: 1. Using CreateStructGEP on an array type. (this causes the majority of the test differences, as struct GEPs are created with i32 indices, while array GEPs are created with i64 indices) 2. Passing the wrong Offset to CreateStructGEP in TargetInfo.cpp on x86-64 NACL (which uses 32-bit pointers). Differential Revision: https://reviews.llvm.org/D57766 llvm-svn: 353529
* Revert "[CodeGenCXX] Treat 'this' as noalias in constructors"Sean Fertile2018-10-151-1/+1
| | | | | | | This reverts commit https://reviews.llvm.org/rL344150 which causes MachineOutliner related failures on the ppc64le multistage buildbot. llvm-svn: 344526
* [CodeGenCXX] Treat 'this' as noalias in constructorsAnton Bikineev2018-10-101-1/+1
| | | | | | | | | This is currently a clang extension and a resolution of the defect report in the C++ Standard. Differential Revision: https://reviews.llvm.org/D46441 llvm-svn: 344150
* CodeGen: Insert addr space cast for automatic/temp var at right positionYaxun Liu2017-07-181-6/+27
| | | | | | | | | | | The uses of alloca may be in different blocks other than the block containing the alloca. Therefore if the alloca addr space is non-zero and it needs to be casted to default address space, the cast needs to be inserted in the same BB as the alloca insted of the current builder insert point since the current insert point may be in a different BB.

* [AMDGPU] Fix size and alignment of size_t and pointer typesYaxun Liu2017-07-051-4/+6

* CodeGen: Cast temporary variable to proper address spaceYaxun Liu2017-06-191-3/+13
| | | | | | | | | | | | | | | | In C++ all variables are in default address space. Previously change has been made to cast automatic variables to default address space. However that is not sufficient since all temporary variables need to be casted to default address space. This patch casts all temporary variables to default address space except those for passing indirect arguments since they are only used for load/store. This patch only affects target having non-zero alloca address space. Differential Revision: https://reviews.llvm.org/D33706 llvm-svn: 305711
* CodeGen: Cast alloca to expected address spaceYaxun Liu2017-05-181-0/+72
Alloca always returns a pointer in alloca address space, which may be different from the type defined by the language. For example, in C++ the auto variables are in the default address space. Therefore cast alloca to the expected address space when necessary. Differential Revision: https://reviews.llvm.org/D32248 llvm-svn: 303370
