Macro Definition Documentation

#define MD_TRAP_COMPILER_FIXUP	(		xpc,
			ra,
			sp,
			pv
	)

Value:

do { \
        (xpc) = (void*) (((uintptr_t) (ra)) - 4); \
    } while(0)

Macro to fixup a compiler stub.

The XPC is the RA minus 4, because the RA points to the instruction after the call.

#define TRAP_INSTRUCTION_IS_LOAD   0

Trap number defines.

On this architecture (Aarch64) we use illegal instructions as trap instructions. Since the illegal instruction with the value 1 is used by the kernel to generate a SIGTRAP, we skip this one.
