elf - How to load text (not binary) debugging informaton from a seperate file with GDB? -


i have elf executable looks this:

$ hexcat hello 00000000:  7f 45 4c 46  01 01 01 00  00 00 00 00  00 00 00 00  .elf............ 00000010:  02 00 03 00  01 00 00 00  d7 80 04 08  34 00 00 00  ............4... 00000020:  00 00 00 00  00 00 00 00  34 00 20 00  01 00 00 00  ........4. ..... 00000030:  00 00 00 00  01 00 00 00  00 00 00 00  00 80 04 08  ................ 00000040:  00 80 04 08  e2 80 04 08  e2 80 04 08  05 00 00 00  ................ 00000050:  00 10 00 00  b8 04 00 00  00 8b 5c 24  04 8b 4c 24  ..........\$..l$ 00000060:  0c 8b 54 24  08 cd 80 c3  55 8b ec 6a  01 ff 75 0c  ..t$....u..j..u. 00000070:  ff 75 08 ff  75 fc ba 04  00 00 00 33  c0 e8 d2 ff  .u..u......3.... 00000080:  ff ff 8d 65  fc 50 e8 01  00 00 00 0a  6a 01 6a 01  ...e.p......j.j. 00000090:  ba 04 00 00  00 33 c0 e8  b8 ff ff ff  8d 65 fc 50  .....3.......e.p 000000a0:  c9 c3 55 8b  ec e8 0d 00  00 00 48 65  6c 6c 6f 2c  ..u.......hello, 000000b0:  20 57 6f 72  6c 64 21 6a  0d 33 d2 33  c0 e8 a6 ff   world!j.3.3.... 000000c0:  ff ff 8d 65  00 6a 00 8b  45 fc c9 c3  8b 5c 24 04  ...e.j..e....\$. 000000d0:  b8 01 00 00  00 cd 80 e8  c6 ff ff ff  50 e8 ea ff  ............p... 000000e0:  ff ff                                               ..

i have file of symbol table information looks this:

$ cat hello.debug rec 8048054 8048068 code write rec 804808b 804808c string _tmp_2 rec 8048068 80480a2 code printl rec 80480aa 80480b7 string _tmp_4 rec 80480a2 80480cc code main rec 80480cc 80480d7 code exit rec 80480d7 80480e2 code _start

i use latter when debugging former; how feed information gdb?

(the actual program trying debug larger; example.)

how feed information gdb?

i don't believe can.

your best bet feed information tool create new elf file symbol table described hello.debug (this should easy generating assembly file appropriate .set directives (documentation) , compiling/linking result), , feed that new elf file gdb add-symbol-file.
