Hi All,
I am developing with mips-linux toolchain. I always need to do some
analysis on the disassembly code.
But objdump displays as following:
----------------------------------------------------------------------------------------
0001c370 <semget>:
1c370: 3c1c0005 lui gp,0x5
1c374: 279ce080 addiu gp,gp,-8064
1c378: 0399e021 addu gp,gp,t9
1c37c: 27bdffd8 addiu sp,sp,-40
1c380: afbf0024 sw ra,36(sp)
1c384: afbc0018 sw gp,24(sp)
1c388: 00a01021 move v0,a1
1c38c: 00c03821 move a3,a2
1c390: 00403021 move a2,v0
1c394: 8f828880 lw v0,-30592(gp)
1c398: 8f998204 lw t9,-32252(gp)
1c39c: 2403ffff li v1,-1
1c3a0: ac430000 sw v1,0(v0)
1c3a4: 00802821 move a1,a0
1c3a8: afa00010 sw zero,16(sp)
1c3ac: afa00014 sw zero,20(sp)
1c3b0: 0320f809 jalr t9
1c3b4: 24040002 li a0,2
1c3b8: 8fbf0024 lw ra,36(sp)
1c3bc: 8fbc0018 lw gp,24(sp)
1c3c0: 03e00008 jr ra
1c3c4: 27bd0028 addiu sp,sp,40
----------------------------------------------------------------------------------------
It is really hard to read disassembly code like that since I can't see which
function is called from `jalr t9'.
Is there some way to inform objdump to display more friendly symbolic name
as following?
bfc020f8 <try_nand_flash_boot>:
bfc020f8: 27bdffe0 addiu sp,sp,-32
bfc020fc: 3c02b404 lui v0,0xb404
bfc02100: afbf001c sw ra,28(sp)
bfc02104: afb20018 sw s2,24(sp)
bfc02108: afb10014 sw s1,20(sp)
bfc0210c: afb00010 sw s0,16(sp)
bfc02110: 00809021 move s2,a0
bfc02114: 0ff007a0 jal bfc01e80 <reset_gpio>
bfc02118: 24501000 addiu s0,v0,4096
bfc0211c: 0ff007f9 jal bfc01fe4 <nand_flash_init>
