The following code compiles for Sparc prior to version 119382 but causes
a llc to hang in version 119382 and later. I glanced at it but haven't
figure it out yet. I figure I'd ping the list to see if it's an obvious
fix to someone else.
define void @test(i16 %di, i32 %L_num, i32 %tmp1, i16* %P) {
%X = shl i16 %di, 1 ; <i16> [#uses=1]
%tmp28 = shl i32 %L_num, 1 ; <i32> [#uses=1]
%tmp31 = icmp slt i32 %tmp28, %tmp1 ; <i1> [#uses=1]
%tmp31.upgrd = zext i1 %tmp31 to i16 ; <i16> [#uses=1]
%tmp371 = or i16 %tmp31.upgrd, %X ; <i16> [#uses=1]
%div.0.be.i.i.i.i = xor i16 %tmp371, 1 ; <i16> [#uses=1]
store i16 %div.0.be.i.i.i.i, i16* %P
ret void
}
