Hello, I need to read the address of local variable, global variable, function name and function arguments from the process.
For global variables , I read the address "55b51afea000" from /proc/<pid>/maps file. I use DW_OP_addr parameter to retrieve the address. 55b51afea000 + DW_OP_addr gives me the address of global variable. I need to read the stack segment, heap. Is there any way to read segments? DW_AT_segment parameter seems to be for 16 bit. I need to read the following process map using dwarf. Any suggestion, pointers are welcome. 55b51afea000-55b51afeb000 r-xp 00000000 fd:00 5902563 55b51b1ea000-55b51b1eb000 r--p 00000000 fd:00 5902563 55b51b1eb000-55b51b1ec000 rw-p 00001000 fd:00 5902563 55b51c094000-55b51c0b5000 rw-p 00000000 00:00 0 [heap] 7fca24956000-7fca24957000 rwxp 00000000 00:00 0 7fca24958000-7fca24959000 rwxp 00000000 00:00 0 7fca2496d000-7fca2496f000 rwxp 00000000 00:00 0 7fca24974000-7fca24975000 rwxp 00000000 00:00 0 7fca2497f000-7fca24980000 rwxp 00000000 00:00 0 7fca24983000-7fca2498c000 rwxp 00000000 00:00 0 7fca2498f000-7fca2499a000 rwxp 00000000 00:00 0 7fca2499b000-7fca24aec000 rwxp 00000000 00:00 0 7fca24aec000-7fca24af8000 rwxp 00000000 00:00 0 7fca24af8000-7fca24afa000 rwxp 00000000 00:00 0 7fca24afa000-7fca24ce1000 r-xp 00000000 fd:00 10230842 7fca24ce1000-7fca24ee1000 ---p 001e7000 fd:00 10230842 7fca24ee1000-7fca24ee5000 r--p 001e7000 fd:00 10230842 7fca24ee5000-7fca24ee7000 rw-p 001eb000 fd:00 10230842 7fca24ee7000-7fca24eeb000 rw-p 00000000 00:00 0 7fca24eeb000-7fca24f2d000 rwxp 00000000 00:00 0 7fca24f2d000-7fca24f32000 rwxp 00000000 00:00 0 7fca24f32000-7fca24f34000 rw-p 00000000 00:00 0 7fca24f34000-7fca24f36000 rwxp 00000000 00:00 0 7fca24f36000-7fca251a0000 rwxp 00000000 00:00 0 7fca251a0000-7fca350e0000 ---p 00000000 00:00 0 7fca350e0000-7fca361f3000 rwxp 00000000 00:00 0 7fca361f3000-7fca36f4b000 rw-p 00000000 00:00 0 7fca36f4b000-7fca36f81000 r--p 00000000 fd:00 5902405 7fca36f81000-7fca3719a000 r-xp 00036000 fd:00 5902405 7fca3719a000-7fca37218000 r--p 0024f000 fd:00 5902405 7fca37218000-7fca3722c000 r--p 002cc000 fd:00 5902405 7fca3722d000-7fca37230000 rw-p 00000000 00:00 0 7fca37230000-7fca37426000 r-xp 00000000 fd:00 5902408 7fca37426000-7fca37625000 ---p 00000000 00:00 0 7fca37625000-7fca37627000 r--p 001f5000 fd:00 5902408 7fca37627000-7fca37629000 rw-p 001f7000 fd:00 5902408 7fca37629000-7fca3764d000 rw-p 00000000 00:00 0 7fca3764d000-7fca376dc000 r-xp 00000000 fd:00 5902391 7fca376dc000-7fca378db000 ---p 00000000 00:00 0 7fca378db000-7fca378de000 r--p 0008e000 fd:00 5902391 7fca378de000-7fca378df000 rw-p 00091000 fd:00 5902391 7fca378df000-7fca37908000 rw-p 00000000 00:00 0 7fca37908000-7fca37937000 r-xp 00000000 fd:00 5902373 7fca37937000-7fca37b36000 ---p 00000000 00:00 0 7fca37b36000-7fca37b37000 r--p 0002e000 fd:00 5902373 7fca37b37000-7fca37b38000 rw-p 0002f000 fd:00 5902373 7fca37b38000-7fca37bd8000 r-xp 00000000 fd:00 5902368 7fca37bd8000-7fca37dd7000 ---p 00000000 00:00 0 7fca37dd7000-7fca37ddb000 r--p 0009f000 fd:00 5902368 7fca37ddb000-7fca37ddc000 rw-p 000a3000 fd:00 5902368 7fca37ddc000-7fca37ddd000 rw-p 00000000 00:00 0 7fca37ddd000-7fca37dec000 r-xp 00000000 fd:00 5902381 7fca37dec000-7fca37feb000 ---p 00000000 00:00 0 Best Regards, Archana
