// bug #1252 - inline asm: cc65 chokes on label ref if space/tab follows
|
|
|

#include <stdlib.h>

// first test the recommended way to use labels in inline assembly:
|
|
|
|
// this works
|

c_label:
|

asm("inx\n"
|
|
"bne %g\n",

// now the following is from the original bug report. note that using labels
|
|
// this way only works by chance - the name of the label may clash with
|
|
// generated labels
|
|
|
|
// this works
|

// this does not work

"bne label2 \n");

|
// a variant of the above using local labels.
|
|
|
|
// this works
