Chandler Carruth a768c4a096 [IC] Fix a bug with the instcombine canonicalizing of loads and ... propagating of metadata. We were propagating !nonnull metadata even when the newly formed load is no longer of a pointer type. This is clearly broken and results in LLVM failing the verifier and aborting. This patch just restricts the propagation of !nonnull metadata to when we actually have a pointer type. This bug report and the initial version of this patch was provided by Charles Davis! Many thanks for finding this! We still need to add logic to round-trip the metadata correctly if we combine from pointer types to integer types and then back by using range metadata for the integer type loads. But this is the minimal and safe version of the patch, which is important so we can backport it into 3.6. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@229029 91177308-0d34-0410-b5e6-96231b3b80d8		2015-02-13 02:30:01 +00:00
