Chris Lattner cee56e7d33 generalize the previous code to use the full generality of LEA ... for i32/i64 expressions (we could also do i16 on cpus where i16 lea is fast, but I didn't add this). On the example, we now generate: _test: movl 4(%esp), %eax cmpl $42, (%eax) setl %al movzbl %al, %eax leal 4(%eax,%eax,8), %eax ret instead of: _test: movl 4(%esp), %eax cmpl $41, (%eax) movl $4, %ecx movl $13, %eax cmovg %ecx, %eax ret git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66869 91177308-0d34-0410-b5e6-96231b3b80d8		2009-03-13 05:53:31 +00:00
