From 5f6208778ff92567c57d7c1e2e740c284d7e69a5 Mon Sep 17 00:00:00 2001 From: Nicola Zaghen Date: Mon, 2 Dec 2019 11:13:43 +0000 Subject: [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.
