Philip Reames e27a387f8e [BasicAA] Fix a bug with relational reasoning across iterations ... Due to the recursion through phis basicaa does, the code needs to be extremely careful not to reason about equality between values which might represent distinct iterations. I'm generally skeptical of the correctness of the whole scheme, but this particular patch fixes one particular instance which is demonstrateable incorrect. Interestingly, this appears to be the second attempted fix for the same issue. The former fix is incomplete and doesn't address the actual issue.

llvm	[BasicAA] Fix a bug with relational reasoning across iterations	2020-12-05 14:10:21 -08:00
llvm-c	Creating a named struct requires only a Context and a name, but looking up a struct by name requires a Module. The method on Module merely accesses the LLVMContextImpl and no data from the module itself, so this patch moves getTypeByName to a static method on StructType that takes a Context and a name.	2020-11-30 11:34:12 -08:00
