but the exclusion was there in the original code-base [still in the
vendor's tree too].
(also, the rs6000 pro/epilogue code is not the easiest to navigate).
Assuming that this is because the non-local goto handler needs to find a
register saved at a canonical place, you can try !cfun- >has_nonlocal_label.
This will subsume the original check !(cfun->calls_setjmp && flag_exceptions)
as both the regular SJLJ scheme and the GNAT SJLJ scheme use it.
I can't confirm the assumption, but, if it holds, sounds nicer to me, thanks.
(+Eric) * config/rs6000/rs6000.c (compute_save_world_info): Test cfun->has_nonlocal_label to determine if the out-of-line save world call may be used. ada:
* gcc-interface/Makefile.in (darwin): Provide powerpc64 system implementation. * system-darwin-ppc64.ads: New file.
