Besides just ensuring the gnu notes displays the right bits, how was
this test this?
For testing, maybe one could do something similar to
https://git.lysator.liu.se/nettle/nettle/-/blob/master/testsuite/x86-ibt-test.c?ref_type=head
I've been doing a bunch of these, and my testing has been just running
the existing test suite, built with BTI support
on a BTI enabled system. I did look more closely at the labels and all
the branches are direct so they don't need bti
landing pads. I can test your patch and report back, so really outside
of testing I think my only suggestion is to
swap the bti c with the hint instruction. Apologies for the disclaimer
previously, I forgot our server appends that.
