Hi, thanks for fixing the issue.
But 'd' is a machine specific constraint? This case failed on all arm
processors.
Hi,
I've rewritten the test-case for C, made the function a valid stdargs function,
and removed the superfluous inline assembly.
Committed as attached.
Thanks,

* g++.dg/pr65802.C: Move to ...
* gcc.dg/pr65802.c: ... here. Add -fexceptions to dg-options. Include
stdarg.h. Rewrite for C.
(fn1): Use va_list and va_arg. Make variable args function. Add use of
va_start and va_end. Remove unnecessary inline asm.
