Hallo Pete:
I don't know much about gdbserver, but I thought I'd just build it
anyway. Some constants are missing in your toolchain though.
File GNUSRC/gdb-7.2/gdb/gdbserver/linux-or32-low.c uses register names
like PT_GPR3:
/*!Provide the ptrace "address" of a register.
This must be in GDB order (r0-r1, ppc, npc, sr) to ptrace offset.
As with
regs_or32, we substitute r31 for r0 and NPC for PPC.
*/
/*
--------------------------------------------------------------------------
*/
static int or32_regmap[] = {
PT_GPR31, PT_SP, PT_GPR2, PT_GPR3,
PT_GPR4, PT_GPR5, PT_GPR6, PT_GPR7,
PT_GPR8, PT_GPR9, PT_GPR10, PT_GPR11,
PT_GPR12, PT_GPR13, PT_GPR14, PT_GPR15,
PT_GPR16, PT_GPR17, PT_GPR18, PT_GPR19,
PT_GPR20, PT_GPR21, PT_GPR22, PT_GPR23,
PT_GPR24, PT_GPR25, PT_GPR26, PT_GPR27,
PT_GPR28, PT_GPR29, PT_GPR30, PT_GPR31,
PT_PC, PT_PC, PT_SR
};
File asm/ptrace.h from Jonas Bonn's Linux does define those constants:
/*
* Offsets used by 'ptrace' system call interface.
*/
#define PT_SR 0
#define PT_SP 4
#define PT_GPR2 8
#define PT_GPR3 12
#define PT_GPR4 16
#define PT_GPR5 20
#define PT_GPR6 24
#define PT_GPR7 28
#define PT_GPR8 32
#define PT_GPR9 36
#define PT_GPR10 40
#define PT_GPR11 44
#define PT_GPR12 48
#define PT_GPR13 52
#define PT_GPR14 56
#define PT_GPR15 60
#define PT_GPR16 64
#define PT_GPR17 68
#define PT_GPR18 72
#define PT_GPR19 76
#define PT_GPR20 80
#define PT_GPR21 84
#define PT_GPR22 88
#define PT_GPR23 92
#define PT_GPR24 96
#define PT_GPR25 100
#define PT_GPR26 104
#define PT_GPR27 108
#define PT_GPR28 112
#define PT_GPR29 116
#define PT_GPR30 120
#define PT_GPR31 124
#define PT_PC 128
#define PT_ORIG_GPR11 132
#define PT_SYSCALLNO 136
However, your asm/ptrace.h does not define them.
The question is, is it safe to define those constants locally, or are
those indexes different in your Linux Kernel version?
Thanks in advance,
rdiez
