[PATCH,RFC,V4 6/8] readelf/objdump: support for CTF Frame section
Indu Bhagat
indu.bhagat@oracle.com
Mon Jun 27 23:47:17 GMT 2022
[Changes from V3]
- Add a string "[m]" to mark FDE of type
CTF_FRAME_DESCRIPTOR_ENTRY_TYPE_ADDRMASK as shown here:
func idx [1]: pc = 0x401030, size = 64 bytes
STARTPC[m] CFA FP RA
0000000000000000 sp+8 u u
000000000000000b sp+16 u u
[End of changes from V3]
[Changes from V2]
- consistent use of terminology around CTF Frame and its components.
[End of changes from V2]
[Changes from V1]
- readelf/objdump: spit out an introduction message - "Contents of the
CTF Frame section XX"
- readelf/objdump: use spaces instead of tabs for alignment of the
textual dump.
[End of changes from V1]
This patch adds support for CTF Frame in readelf and objdump.
include/ChangeLog:
* ctf-frame-api.h (dump_ctf_frame): New function declaration.
ChangeLog:
