You might also want to look at Alpha's pattern for this:
(define_insn_and_split "*fix_truncdfsi_internal"
[(set (match_operand:SI 0 "memory_operand" "=m")
(subreg:SI (fix:DI (match_operand:DF 1 "reg_or_0_operand" "fG")) 0))
(clobber (match_scratch:DI 2 "=f"))]
"TARGET_FP && alpha_fptm < ALPHA_FPTM_SU"
"#"
"&& reload_completed"
[(set (match_dup 2) (fix:DI (match_dup 1)))
(set (match_dup 3) (unspec:SI [(match_dup 2)] UNSPEC_CVTQL))
(set (match_dup 0) (match_dup 3))]
;; Due to REG_CANNOT_CHANGE_SIZE issues, we cannot simply use SUBREG.
"operands[3] = gen_rtx_REG (SImode, REGNO (operands[2]));"
[(set_attr "type" "fadd")
(set_attr "trap" "yes")])
