Evan Cheng	ef2509b3ba	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. llvm-svn: 55139	2008-08-21 21:00:15 +00:00
Dan Gohman	cf79877623	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. llvm-svn: 49761	2008-04-16 01:32:32 +00:00
