- Subject: some questions about gdb
hi all:
I have some questions about using gdb
1. I compile the kernel with -g but I cannot see the disassembly.
My pc increase 4 when I type 'n' but I cannot see the disassembly.
Program received signal 0, Signal 0.
0x8043e59c in kernel_entry () at arch/mips/kernel/head.S:97
97 #else
(gdb) n
Program received signal 0, Signal 0.
0x8043e5a0 in kernel_entry () at arch/mips/kernel/head.S:97
97 #else
(gdb) si
Program received signal 0, Signal 0.
0x8043e5a4 in kernel_entry () at arch/mips/kernel/head.S:97
97 #else
(gdb)
Did I miss any configuration?
2. I search gdb and which tell me there is a command, disassemble /m,
which can mix source and assembly.
But I use it on my mips platform, it said:
(gdb) disassemble /m irq_enter
A syntax error in expression, near `/m'.
(gdb) list
276 void irq_enter(void)
277 {
278 int cpu = smp_processor_id();
279
280 rcu_irq_enter();
281 if (idle_cpu(cpu) && !in_interrupt()) {
282 __irq_enter();
283 tick_check_idle(cpu);
284 } else
285 __irq_enter();
(gdb)
3. is any document about how to compile insight6.8.1 with mips gdb 7.2?
I google it and I found for arm version
http://old.nabble.com/patch-for-insight-6.8.1-to29485252.html
if I do the same thing for mips gdb, should I patch gdb?
