Chris Lattner 67f453aae7 Finish implementing a readme entry: when inserting an i64 variable ... into a vector of zeros or undef, and when the top part is obviously zero, we can just use movd + shuffle. This allows us to compile vec_set-B.ll into: _test3: movl $1234567, %eax andl 4(%esp), %eax movd %eax, %xmm0 ret instead of: _test3: subl $28, %esp movl $1234567, %eax andl 32(%esp), %eax movl %eax, (%esp) movl $0, 4(%esp) movq (%esp), %xmm0 addl $28, %esp ret git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48090 91177308-0d34-0410-b5e6-96231b3b80d8		2008-03-09 05:42:06 +00:00
