PATCH : allmul fixed

allmul fixed

allmul produced wrong results when the higher 32 bits of any of the 64 bit operands are not zero.
As the comment correctly said the definition of param locations must change since esp was altered, but the definitions were not actually changed

Patch follows

file allmul_asm.s line 94:
// must redefine A and B since esp has been altered

-#define A2LO [esp + 4] // stack address of a
+#define A2LO [esp + 8] // stack address of a
-#define A2HI [esp + 8] // stack address of a
+#define A2HI [esp + 12] // stack address of a
-#define B2LO [esp + 12] // stack address of b
+#define B2LO [esp + 16] // stack address of b
-#define B2HI [esp + 16] // stack address of b
+#define B2HI [esp + 20] // stack address of b

test:
i64 t1 = 12908046380;
i64 t2 = 10000000;
i64 t3;

t3 = t1 * t2;
DPRINT("t1=%016I64x=%I64d\n", t1, t1);
DPRINT("t2=%016I64x=%I64d\n", t2, t2);
DPRINT("t3=%016I64x=%I64d\n", t3, t3);
return 0;

t1=000000030161282c=12908046380
t2=0000000000989680=10000000
t3=01ca95ff783dde00=129080463800000000
(before the patch t3 value was wrong)
