It is missing validity checks, so it is known broken. However, it is powerful enough to compile this contrived code: void test1(int C, double A, double B, double *P) { double Tmp = A*A+B*B; *P = C ? Tmp : A; } into: _test1: movsd 8(%esp), %xmm0 cmpl $0, 4(%esp) je LBB1_2 # entry LBB1_1: # entry movsd 16(%esp), %xmm1 mulsd %xmm1, %xmm1 mulsd %xmm0, %xmm0 addsd %xmm1, %xmm0 LBB1_2: # entry movl 24(%esp), %eax movsd %xmm0, (%eax) ret instead of: _test1: movsd 16(%esp), %xmm0 mulsd %xmm0, %xmm0 movsd 8(%esp), %xmm1 movapd %xmm1, %xmm2 mulsd %xmm2, %xmm2 addsd %xmm0, %xmm2 cmpl $0, 4(%esp) je LBB1_2 # entry LBB1_1: # entry movapd %xmm2, %xmm1 LBB1_2: # entry movl 24(%esp), %eax movsd %xmm1, (%eax) ret woo. llvm-svn: 45570
