-The X86 backend should be able to if-convert SSE comparisons like "ucomisd" to
-"cmpsd". For example, this code:
-
-double d1(double x) { return x == x ? x : x + x; }
-
-Compiles into:
-
-_d1:
- ucomisd %xmm0, %xmm0
- jnp LBB1_2
- addsd %xmm0, %xmm0
- ret
-LBB1_2:
- ret
-
-Also, the 'ret's should be shared. This is PR6032.
