You don't need gcond_name, gcond can be used directly in the pattern:
-(define_insn "fcmpeq32<P:mode>_vis"
+(define_insn "fcmp<gcond_name><gcm_name><P:mode>_vis"
(define_insn "fcmp<gcond:code><gcm_name><P:mode>_vis"
[(set (match_operand:P 0 "register_operand" "=r")
- (unspec:P [(match_operand:V2SI 1 "register_operand" "e")
- (match_operand:V2SI 2 "register_operand" "e")]
- UNSPEC_FCMPEQ))]
+ (unspec:P [(gcond:GCM (match_operand:GCM 1 "register_operand" "e")
+ (match_operand:GCM 2 "register_operand" "e"))]
+ UNSPEC_FCMP))]
"TARGET_VIS"
- "fcmpeq32\t%1, %2, %0"
+ "fcmp<gcond_name><gcm_name>\t%1, %2, %0"
"fcmp<gcond:code>..."
[(set_attr "type" "fpmul")
(set_attr "fptype" "double")])
Uros.
