Author: Nicola Zaghen Date: 2019-12-12T10:07:01Z New Revision: 5f6208778ff92567c57d7c1e2e740c284d7e69a5
URL: https://github.com/llvm/llvm-project/commit/5f6208778ff92567c57d7c1e2e740c284d7e69a5 DIFF: https://github.com/llvm/llvm-project/commit/5f6208778ff92567c57d7c1e2e740c284d7e69a5.diff LOG: [DataLayout] Fix occurrences that size and range of pointers are assumed to be the same. GEP index size can be specified in the DataLayout, introduced in D42123. However, there were still places in which getIndexSizeInBits was used interchangeably with getPointerSizeInBits. This notably caused issues with Instcombine's visitPtrToInt; but the unit tests was incorrect, so this remained undiscovered.
