Owen Anderson 9b636cb338 Teach getModRefInfo that memcpy, memmove, and memset don't "capture" memory addresses. ... Also, noalias arguments are be considered "like" stack allocated ones for this purpose, because the only way they can be modref'ed is if they escape somewhere in the current function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47247 91177308-0d34-0410-b5e6-96231b3b80d8		2008-02-17 21:29:08 +00:00

CodeGen	I cannot find a libgcc function for this builtin. Therefor expanding it to a noop (which is how it use to be treated). If someone who knows the x86 backend better than me could tell me how to get a lock prefix on an instruction, that would be nice to complete x86 support.	2008-02-16 14:46:26 +00:00
