Chris Lattner [Tue, 11 Jan 2005 03:11:44 +0000 (03:11 +0000)]
Take register pressure into account when we have to decide whether to
evaluate the LHS or the RHS of an operation first.  This causes good things
to happen.  For example, instead of compiling a loop to this:

.LBBstrength_result7_1: # loopentry
        movl 16(%esp), %edi
        movl (%edi), %edi             ;;; LOAD
        movl (%ecx), %ebx
        movl $2, (%eax,%ebx,4)
        movl (%edx), %ebx
        movl %esi, %ebp
        addl $21, %ebp
        addl $42, %esi
        cmpl $0, %edi                 ;;; USE
        cmovne %esi, %ebp
        cmpl %ebp, %ebx
        movl %ebp, %esi
        jg .LBBstrength_result7_1

We now compile it to this:

.LBBstrength_result7_1: # loopentry
        movl %edi, %ebx
        addl $42, %ebx
        addl $21, %edi
        movl (%ecx), %ebp              ;; LOAD
        cmpl $0, %ebp                  ;; USE
        cmovne %ebx, %edi
        movl (%edx), %ebx
        movl $2, (%eax,%ebx,4)
        movl (%esi), %ebx
        cmpl %edi, %ebx
        jg .LBBstrength_result7_1

Which reduces register pressure enough (in this case) to avoid spilling in the
loop.

As another example, consider the CodeGen/X86/regpressure.ll testcase.  We
used to generate this code for both cases:

regpressure1:
        subl $32, %esp
        movl %esi, 12(%esp)
        movl %edi, 8(%esp)
        movl %ebx, 4(%esp)
        movl %ebp, (%esp)
        movl 36(%esp), %ecx
        movl (%ecx), %eax
        movl 4(%ecx), %edx
        movl %edx, 24(%esp)
        movl 8(%ecx), %edx
        movl %edx, 16(%esp)
        movl 12(%ecx), %edx
        movl 16(%ecx), %esi
        movl 20(%ecx), %edi
        movl 24(%ecx), %ebx
        movl %ebx, 28(%esp)
        movl 28(%ecx), %ebx
        movl 32(%ecx), %ebp
        movl %ebp, 20(%esp)
        movl 36(%ecx), %ecx
        imull 24(%esp), %eax
        imull 16(%esp), %eax
        imull %edx, %eax
        imull %esi, %eax
        imull %edi, %eax
        imull 28(%esp), %eax
        imull %ebx, %eax
        imull 20(%esp), %eax
        imull %ecx, %eax
        movl (%esp), %ebp
        movl 4(%esp), %ebx
        movl 8(%esp), %edi
        movl 12(%esp), %esi
        addl $32, %esp
        ret

This code is basically trying to do all of the loads first, then execute all
of the multiplies.  Because we run out of registers, lots of spill code happens.
We now generate this code for both cases:

regpressure1:
        movl 4(%esp), %ecx
        movl (%ecx), %eax
        movl 4(%ecx), %edx
        imull %edx, %eax
        movl 8(%ecx), %edx
        imull %edx, %eax
        movl 12(%ecx), %edx
        imull %edx, %eax
        movl 16(%ecx), %edx
        imull %edx, %eax
        movl 20(%ecx), %edx
        imull %edx, %eax
        movl 24(%ecx), %edx
        imull %edx, %eax
        movl 28(%ecx), %edx
        imull %edx, %eax
        movl 32(%ecx), %edx
        imull %edx, %eax
        movl 36(%ecx), %ecx
        imull %ecx, %eax
        ret

which is much nicer (when we fold loads into the muls it will be even better).
The old instruction selector used to produce the good code for regpressure1
but not for regpressure2, as it depended on the order of operations in the
LLVM code.
