I'm moving a CFM project from CodeWarrior to Xcode and Mach-o and I've run into a problem when compiling some assembly. I've got a function as follows:
static asm unsigned long Mul32Shft16r( register unsigned long val1, register unsigned long val2 )
{
// a bunch of assmebly that compiles fine
// ...
// v-- then I get a problem with this line --v
or r3,r30,r31
}
The problem I get is as follows:
<x-tad-smaller>error: parse error before `||' token
</x-tad-smaller>Does anyone have any suggestions? It's like GCC is converting the "or" into a "||" and then getting confused. This is the only bit of assembly that doesn't compile, everything else works fine.
"or" is a reserved word in C++ (you'll see it changes colour when you type it in). It one of a group of alternative representations for operators. I suspect, as you say, that the compiler just changes it to ||. I don't know what your workround is - maybe compile as C instead of C++?
