Alexandros Lamprineas 8d73ea30c1 [MemorySSAUpdater] Avoid creating self-referencing MemoryDefs ... Fix for https://bugs.llvm.org/show_bug.cgi?id=38807, which occurred while compiling SemaTemplateInstantiate.cpp with clang and GVNHoist enabled. In the following example: 1=def(entry) / \ 2=def(1) 4=def(1) 3=def(2) 5=def(4) When removing the MemoryDef 2=def(1) from its basic block, and just before adding it to the end of the parent basic block, we first replace all its uses with the defining memory access: 3=def(2) -> 3=def(1) Then we call insertDef for adding 2=def(1) to the parent basic block, where we replace the uses of 1=def(entry) with 2=def(1). Doing so we create a self reference: 2=def(1) -> 2=def(2) (bad) 3=def(1) -> 3=def(2) (ok) 4=def(1) -> 4=def(2) (ok) Differential Revision: https://reviews.llvm.org/D51801 llvm-svn: 341947		2018-09-11 14:29:59 +00:00
