You are missing the "commas" in that assembly code (just as the error is
telling you).

RE: assembly macro syntax...

[Noonan, Michael E (Michael)]

ok...  i have gotten a little further and have a new issue...  basically all
the macros that i converted are compiling without error, but there when i
try and use the output of any of them, the compiler chokes on it with the
error message shown below.  The actual code is also shown....  and all it
does is read from a gpr and then prints the result (output).  If i co the
printf statement, it compiles without error.

Any help is appreciated.  Thanks, Mike

   __asm__ ( "mr %0 %1" : "=&r" (output) : "r" (1) );

//   __asm__ ( "or %0 %1 %2" : "=g" (output) : "g" (1), "g" (1) );

   dprintf (DPRINT_LF, "Current r1 Stack: 0x%x.", output );
