Chris Lattner 68dc310942 Implement a couple of more simplifications. This lets us codegen: ... int test2(int * P, int* Q, int A, int B) { return P+A == P; } into: test2: movl 4(%esp), %eax movl 12(%esp), %eax shll $2, %eax cmpl $0, %eax sete %al movzbl %al, %eax ret instead of: test2: movl 4(%esp), %eax movl 12(%esp), %ecx leal (%eax,%ecx,4), %ecx cmpl %eax, %ecx sete %al movzbl %al, %eax ret ICC is producing worse code: test2: movl 4(%esp), %eax #8.5 movl 12(%esp), %edx #8.5 lea (%edx,%edx), %ecx #9.9 addl %ecx, %ecx #9.9 addl %eax, %ecx #9.9 cmpl %eax, %ecx #9.16 movl $0, %eax #9.16 sete %al #9.16 ret #9.16 as is GCC (looks like our old code): test2: movl 4(%esp), %edx movl 12(%esp), %eax leal (%edx,%eax,4), %ecx cmpl %edx, %ecx sete %al movzbl %al, %eax ret git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19430 91177308-0d34-0410-b5e6-96231b3b80d8		2005-01-10 02:03:02 +00:00
