Hi,
Binutils 2.41 release (planned to be released soon) will feature SFrame
version 2. One of main changes in SFrame version 2 is that the SFrame
Function Descriptor Entry (FDE) is now 20 bytes. This keeps all data
members of SFrame FDE naturally aligned.
All data structures continue to be packed in the on-disk representation.
SFrame FREs (Frame Row Entries) will continue to potentially have
members not aligned at their natural boundaries (Recall that SFrame FREs
are variable length entries).
Changes have been made to the GNU as, ld, objdump/readelf support: the
default version supported is SFrame version 2. The SFrame spec has also
been updated.

Hi Indu,
I did a quick check for SFrame in LLVM's issue tracker and noticed
there were no pending issues on file.
https://github.com/llvm/llvm-project/issues?q=is%3Aissue+is%3Aopen+SFrame
Mind filing a ticket there linking to the relevant specs?

Sure. I can file it once the SPEC (pdf/html) is published with the 2..41
release ?
