Re: [PATCH] microblaze: add Linux signal frame unwinding support

Hi Michael,

could you also cherry-pick 4ef64ad1a to releases/gcc-16?

The gcc-16 branch was cut on April 22nd, seven weeks before the commit
landed on master, so the 16 series is the one gap: gcc 15.3 has the fix,
master (17) has it, but 16.1/16.2 ship without microblaze signal-frame
unwinding.  Anyone moving from 15.3 to 16.x gets a regression -- pthread
cancellation cleanup stops working.  Verified with gcc 16.2.0 against the
uClibc-ng test suite: 12 tests fail (tst-cancelx*/tst-oncex*, "cleanup
handler not called"), and all pass again with the commit cherry-picked
onto 16.2.0.

best regards
 Ramin
