Support for SFrame format is available in Binutils 2.40. The GNU ld merges
the input .sframe sections and creates an output .sframe section in a
segment PT_GNU_SFRAME.

Please submit this to the gnu-gabi list as well, preferably with a
documentation patch.
Thanks,

Thanks. A patch was posted to gnu-gabi
https://sourceware.org/pipermail/gnu-gabi/2023q1/000522.html
(BTW, on the Binutils side, the patch to update documentation to use
"stack trace" instead of "unwind" for SFrame, has been committed).
Thanks
Indu
