Add explicit triples to avoid default behavior that varies by host. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41510 91177308-0d34-0410-b5e6-96231b3b80d8 2007-08-27 20:54:48 +00:00			`; RUN: llvm-as < %s \| llc -march=x86 -mtriple=i686-pc-linux-gnu \| not grep call`
If the source and destination pointers in an llvm.memmove are known to not alias each other, it can be translated as an llvm.memcpy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41489 91177308-0d34-0410-b5e6-96231b3b80d8 2007-08-27 16:26:13 +00:00
