ret
//===---------------------------------------------------------------------===//
+
+Consider the expansion of:
+
+uint %test3(uint %X) {
+ %tmp1 = rem uint %X, 255
+ ret uint %tmp1
+}
+
+Currently it compiles to:
+
+...
+ movl $2155905153, %ecx
+ movl 8(%esp), %esi
+ movl %esi, %eax
+ mull %ecx
+...
+
+This could be "reassociated" into:
+
+ movl $2155905153, %eax
+ movl 8(%esp), %ecx
+ mull %ecx
+
+to avoid the copy. In fact, the existing two-address stuff would do this
+except that mul isn't a commutative 2-addr instruction. I guess this has
+to be done at isel time based on the #uses to mul?
