Remove some redundant checks, add a couple of new ones. This allows us to
compile this: int foo (unsigned long a, unsigned long long g) { return a >= g; } To: foo: movl 8(%esp), %eax cmpl %eax, 4(%esp) setae %al cmpl $0, 12(%esp) sete %cl andb %al, %cl movzbl %cl, %eax ret instead of: foo: movl 8(%esp), %eax cmpl %eax, 4(%esp) setae %al movzbw %al, %cx movl 12(%esp), %edx cmpl $0, %edx sete %al movzbw %al, %ax cmpl $0, %edx cmove %cx, %ax movzbl %al, %eax ret git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21244 91177308-0d34-0410-b5e6-96231b3b80d8
