+ ulong %foo(ulong %y) {
+ entry:
+ %tmp = and ulong %y, 65535
+ %tmp2 = shr ulong %tmp, ubyte 3
+ ret ulong %tmp2
+ }
+
+
+ compiles to a 3 instruction sequence without instcombine
+ zapnot $16,3,$0
+ srl $0,3,$0
+ ret $31,($26),1
+
+ After instcombine you get
+ ulong %foo(ulong %y) {

+ %tmp = shr ulong %y, ubyte 3 ; <ulong> [#uses=1]
+ %tmp2 = and ulong %tmp, 8191 ; <ulong> [#uses=1]
+ ret ulong %tmp2
+ }
+
+ which compiles to
+ lda $0,8191($31)
+ srl $16,3,$1
+ and $1,$0,$0
+ ret $31,($26),1
