Evan Cheng	1887c1c2f9	Fix a number of byval / memcpy / memset related codegen issues. 1. x86-64 byval alignment should be max of 8 and alignment of type. Previously the code was not doing what the commit message was saying. 2. Do not use byte repeat move and store operations. These are slow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55139 91177308-0d34-0410-b5e6-96231b3b80d8	2008-08-21 21:00:15 +00:00
Dan Gohman	bcda285fcc	Recreate the size SDNode instead of reusing the old one in the x86 memcpy lowering code; this ensures that the size node has the desired result type. This fixes a regression from r49572 with @llvm.memcpy.i64 on x86-32. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49761 91177308-0d34-0410-b5e6-96231b3b80d8	2008-04-16 01:32:32 +00:00

Recreate the size SDNode instead of reusing the old one in the x86

memcpy lowering code; this ensures that the size node has the desired
result type. This fixes a regression from r49572 with @llvm.memcpy.i64
on x86-32.
