Hi,
The support -combine was removed a while back but cc1 still accepts
more than one file if directly invoked. The support for multiple
files has bit-rotten inside the C front-end now too. This patch now
errors out when invoked with more than one file instead of crashing
later.
OK? Bootstrapped and tested on aarch64-linux-gnu with no regressions.
Thanks,
Andrew Pinski
c-family/ChangeLog:
* c-opts.c (c_common_post_options): Move the error message about "two
or more source files" such that it is unconditional.
