Hi Stuart -
This is really a C/C++ question, and not really a gcc/c++ question.
However, in C, you can't pass things by reference (the &), you should
pass by address instead, and then dereference to set the values.

Hi - someone supplied the following code
in a C++ program to me that g++ compiled.
However, I want to convert it to use it in
a regular C program that gcc can compile.
Needless to say, the construct does not work
for GNU C.
I've tried placing each line of the assembly
in asm("...."); and that also fails to get
gcc to compile it.
What would the equivalent GNU C function for the
below be?
static unsigned int bitScanAndReset(unsigned long long & bb) {
__asm
{
xor edx, edx
mov ebx, [bb]
xor eax, eax
inc edx
bsf ecx, [ebx]
jnz found
bsf ecx, [ebx+4]
lea ebx, [ebx+4]
xor eax, 32
found:
shl edx, cl
xor eax, ecx
xor [ebx], edx
}
}
Thanks,
Stuart
