Hello,
RTEMS community is using MPC as a part of GNU C compiler. Recently we
have been hit by an issue of compiling GNU C compiler toolchain on the
Apple M1 hardware. The issue is easily fixable by the patch below, but
RTEMS community refuses to include the fix without a clear sign that
upstream project (you) were contacted and asked either for patch
acceptance or fixing the issue.
Could you be so kind and in next release use latest available autotools
to generate configure script and associated files? This way, problematic
config.sub file is generated with the proper support for Apple M1
hardware and everything should be working again.
Thanks!
Karel Gardas
