[uClinux-dev] include/asm-arm/kgdb.h

Hi,

I was trying to enable kgdb for ixp425 (I've been using snapgear 3.4.0 release).
In kgdb.h we have the following declarations

  void do_kgdb(struct pt_regs *, unsigned char);
  int kgdb_active(void);
  int kgdb_connected(void);
  extern void kgdb_handle_bus_error(void);
  extern int kgdb_setjmp(int *machine_context);
  extern int kgdb_longjmp(int *machine_context, int flag);
  extern int kgdb_fault_expected;

My question is why the first three, do_kgdb, kgdb_active, and kgdb_connected
are not declared extern?

Also, it seems entry-armv.S includes kgdb.h and when compiling, it complained
about these declarations as bad instructions.

        snapgear/linux-2.4.x/include/asm/kgdb.h:24: Error: bad instruction `void do_kgdb(struct
pt_regs*,unsigned char)'
        snapgear/linux-2.4.x/include/asm/kgdb.h:30: Error: bad instruction `int kgdb_active(void)'

        snapgear/linux-2.4.x/include/asm/kgdb.h:76: Error: bad instruction `extern void
kgdb_serial_putchar(unsigned char)'
        snapgear/linux-2.4.x/include/asm/kgdb.h:78: Error: bad instruction `extern void
kgdb_serial_init(void)'

Is there a way to tell the assembler never mind the C-declarations?

Thanks.
Wei
