Fix an inconsistency in the x86 backend that led it to reject "calll foo" on x86-32: 32-bit calls were named "call" not "calll". 64-bit calls were correctly named "callq", so this only impacted x86-32. This fixes rdar://8456370 - llvm-mc rejects 'calll' This also exposes that mingw/64 is generating a 32-bit call instead of a 64-bit call, I will file a bugzilla. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114534 91177308-0d34-0410-b5e6-96231b3b80d8 2010-09-22 05:49:14 +00:00			`; RUN: llc < %s -march=x86 -mtriple=i686-pc-linux-gnu \| grep {calll memcpy}`
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
