I noticed that Coccinelle skips over much of QEMU's hw/arm/armsse.c.
I append a minimized test case. Observations:
* spatch seems to have trouble parsing
ARMSSE *s = ARMSSE(opaque);
where ARMSSE is a typedef, and ARMSSE() is a function-like macro.
Yes, I know that's in rather poor taste.
* Workaround #1: rename the typedef to ARMSSE_
* Workaround #2: move the typedef and the macro from the .h to the .c.
$ cat armsse.c
#include "armsse.h"
void nsccfg_handler(void *opaque, int n, int level)
{
ARMSSE *s = ARMSSE(opaque);
s->nsccfg = level;
}
$ cat armsse.h
#ifndef ARMSSE_H
#define ARMSSE_H
typedef struct {
int nsccfg;
} ARMSSE;
#define ARMSSE(obj) ((ARMSSE *)(obj))
#endif
$ spatch --parse-c armsse.c
