[End of changes in V1]
Thanks
----------------------
Hello,
This patchset adds support for handling the .cfi_b_key_frame assembler
directive to the SFrame format: SFrame format representation now allows to
encode which of the pauth A key / B key are used (for signing return
addresses on aarch64), and gas, readelf/objdump now allow for generation
and textual dump of this information.
Testing notes:
- Regression tested cross build of several targets on an x86_64 host and an
aarch64 host using a regression script that checks for failures in gas, ld,
binutils, libctf and libsframe.
- Regression tested native builds on x86_64 and aarch64.
- binutils/gdb try bot showed no new regressions.
Thanks,
Indu Bhagat (5):
