*	Use movups to lower memcpy and memset even if it's not fast (like corei7).	Evan Cheng	2011-01-06	1	-2/+1
\| \| \| \| \| \| \| \| \|	The theory is it's still faster than a pair of movq / a quad of movl. This will probably hurt older chips like P4 but should run faster on current and future Intel processors. rdar://8817010 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122955 91177308-0d34-0410-b5e6-96231b3b80d8

*	Fix sdisel memcpy, memset, memmove lowering:	Evan Cheng	2010-04-01	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	1. Makes it possible to lower with floating point loads and stores. 2. Avoid unaligned loads / stores unless it's fast. 3. Fix some memcpy lowering logic bug related to when to optimize a load from constant string into a constant. 4. Adjust x86 memcpy lowering threshold to make it more sane. 5. Fix x86 target hook so it uses vector and floating point memory ops more effectively. rdar://7774704 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100090 91177308-0d34-0410-b5e6-96231b3b80d8

*	Fix a number of byval / memcpy / memset related codegen issues.	Evan Cheng	2008-08-21	1	-7/+5
\| \| \| \| \| \| \| \|	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
*	Recreate the size SDNode instead of reusing the old one in the x86	Dan Gohman	2008-04-16	1	-0/+13
	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
