[9fans] kenc vlong <asop> double

[cinap_lenrek@felloff.net]

the following code generates unhandled instructions
for the linker on 64 bit simulating archs (8c, 5c):

vlong v;
double d;
v += d;

 == cgen ==
ASADD DOUBLE (1) a.c:13
   NAME "v" -8 <11> VLONG a.c:13
   NAME "d" -16 <11> DOUBLE a.c:13

term% 8c -S a.c
	...
	FMOVD	d+-16(SP),F0
	MOVL	v+-8(SP),F0			<- nope.
	FADDDP	F0,F1
	MOVL	F0,v+-8(SP)			<- nope.
	RET	,
	END	,

but works on amd64:

term% 6c -S a.c
	...
	CVTSQ2SD	v+-8(SP),X0
	ADDSD	d+-16(SP),X0
	CVTTSD2SQ	X0,CX
	RET	,

the following code works on 8c/5c:

v = v + d;

 == cgen ==
AS VLONG (100) a.c:13
   NAME "v" -8 <11> VLONG a.c:13
   FUNC VLONG (100) a.c:13
      NAME "_d2v" 0 <10> FUNC VLONG a.c:1
      ADD DOUBLE (100) a.c:13
         FUNC DOUBLE (100) a.c:13
            NAME "_v2d" 0 <10> FUNC DOUBLE a.c:1
            NAME "v" -8 <11> VLONG a.c:13
         NAME "d" -16 <11> DOUBLE a.c:13


term% 8c -S a.c
	....
	MOVL	v+-8(SP),AX
	MOVL	AX,(SP)
	MOVL	v+-4(SP),AX
	MOVL	AX,4(SP)
	CALL	,_v2d+0(SB)
	FADDD	d+-16(SP),F0
	FMOVDP	F0,.safe+-28(SP)
	LEAL	v+-8(SP),AX
	MOVL	AX,(SP)
	FMOVD	.safe+-28(SP),F0
	FMOVDP	F0,4(SP)
	CALL	,_d2v+0(SB)

any ideas how to fix this?
