gdbserver/csky add csky gdbserver support
Add new files:
gdb/arch/csky.c
gdb/arch/csky.h
gdb/features/cskyv2-linux.c
gdbserver/linux-csky-low.cc
1. In gdb/arch/csky.c file, add function "csky_create_target_description()"
for csky_target::low_arch_setup(). later, it can be used for csky native gdb.
2. In gdb/features/cskyv2-linux.c file, create target_tdesc for csky, include
gprs, pc, hi, lo, float, vector and float control registers.
3. In gdbserver/linux-csky-low.cc file, using PTRACE_GET/SET_RGESET to
get/set registers. The main data structures in asm/ptrace.h are:
struct pt_regs {
unsigned long tls;
unsigned long lr;
unsigned long pc;
unsigned long sr;
unsigned long usp;
/*
* a0, a1, a2, a3:
* r0, r1, r2, r3
*/
unsigned long orig_a0;
unsigned long a0;
unsigned long a1;
unsigned long a2;
unsigned long a3;
/*
* r4 ~ r13
*/
unsigned long regs[10];
/* r16 ~ r30 */
unsigned long exregs[15];
unsigned long rhi;
unsigned long rlo;
unsigned long dcsr;
};
struct user_fp {
unsigned long vr[96];
unsigned long fcr;
unsigned long fesr;
unsigned long fid;
unsigned long reserved;
};
