Subject: [PATCH] libgcov: Call __builtin_fork instead of fork
Date: Sat, 02 Dec 2023 13:43:22 +0100	[thread overview]
Message-ID: <87edg4epw5.fsf@oldenburg.str.redhat.com> (raw)

Some targets do not provide a prototype for fork, and compilation now
fails with an implicit-function-declaration error.

libgcc/

	* libgcov-interface.c (__gcov_fork):

Generated code is the same on x86_64-linux-gnu.  Okay for trunk?

Thanks,
Florian
