Chris Lattner b6387c8a74 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 llvm-svn: 48090		2008-03-09 05:42:06 +00:00
