Evan Cheng	52ceafa5c7	Use movaps / movd to extract vector element 0 even with sse4.1. It's still cheaper than pextrw especially if the value is in memory. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61555 91177308-0d34-0410-b5e6-96231b3b80d8	2009-01-02 05:29:08 +00:00
Dan Gohman	c5b822b5b6	Convert several tests to use temporary files instead of redundantly ... executing the test commands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52163 91177308-0d34-0410-b5e6-96231b3b80d8	2008-06-10 00:36:41 +00:00
Evan Cheng	14b32e1941	- Improved v8i16 shuffle lowering. It now uses pshuflw and pshufhw as much as ... possible before resorting to pextrw and pinsrw. - Better codegen for v4i32 shuffles masquerading as v8i16 or v16i8 shuffles. - Improves (i16 extract_vector_element 0) codegen by recognizing (i32 extract_vector_element 0) does not require a pextrw. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44836 91177308-0d34-0410-b5e6-96231b3b80d8	2007-12-11 01:46:18 +00:00
Evan Cheng	8a86c3f3ae	Much improved v8i16 shuffles. (Step 1). ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44676 91177308-0d34-0410-b5e6-96231b3b80d8	2007-12-07 08:07:39 +00:00
