Gcc 4.1/4.2/4.3 will fail and gcc 3.4 has no problem:
---
typedef unsigned long bngdigit;
typedef bngdigit *bng;
typedef unsigned int bngcarry;
typedef unsigned long bngsize;
bngdigit
bng_ia32_mult_sub_digit (bng a, bngsize alen, bng b, bngsize blen, bngdigit d)
{
bngdigit out, tmp;
bngcarry carry;
bngdigit a11;
int x = blen;
out = 0;
asm (""
: "+r" (a), "+r" (b), "+mr" (blen), "+mr" (out), "=&r" (tmp)
: "mr" (d)
: "eax", "edx");
if (alen == blen)
{
a11 = out;
goto t;
}
if (x == 0)
goto t;
a11 = 1;
t:
return a11;
}
