2006-04-27Fix some nondeterminstic behavior in the mem2reg pass that (in addition toChris Lattner
nondeterminism being bad) could cause some trivial missed optimizations (dead phi nodes being left around for later passes to clean up). With this, llvm-gcc4 now bootstraps and correctly compares. I don't know why I never tried to do it before... :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27984 91177308-0d34-0410-b5e6-96231b3b80d8

2006-04-21Revamp build_vector lowering to take advantage of movss and movd instructions.Evan Cheng
movd always clear the top 96 bits and movss does so when it's loading the value from memory. The net result is codegen for 4-wide shuffles is much improved. It is near optimal if one or more elements is a zero. e.g. __m128i test(int a, int b) { return _mm_set_epi32(0, 0, b, a); } compiles to _test: movd 8(%esp), %xmm1 movd 4(%esp), %xmm0 punpckldq %xmm1, %xmm0 ret compare to gcc: _test: subl $12, %esp movd 20(%esp), %xmm0 movd 16(%esp), %xmm1 punpckldq %xmm0, %xmm1 movq %xmm1, %xmm0 movhps LC0, %xmm0 addl $12, %esp ret or icc: _test: movd 4(%esp), %xmm0 #5.10 movd 8(%esp), %xmm3 #5.10 xorl %eax, %eax #5.10 movd %eax, %xmm1 #5.10 punpckldq %xmm1, %xmm0 #5.10 movd %eax, %xmm2 #5.10 punpckldq %xmm2, %xmm3 #5.10 punpckldq %xmm3, %xmm0 #5.10 ret #5.10 There are still room for improvement, for example the FP variant of the above example: __m128 test(float a, float b) { return _mm_set_ps(0.0, 0.0, b, a); } _test: movss 8(%esp), %xmm1 movss 4(%esp), %xmm0 unpcklps %xmm1, %xmm0 xorps %xmm1, %xmm1 movlhps %xmm1, %xmm0 ret The xorps and movlhps are unnecessary. This will require post legalizer optimization to handle. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27939 91177308-0d34-0410-b5e6-96231b3b80d8
