Subject: libgcov: Call __builtin_fork instead of fork
X-Git-Tag: basepoints/gcc-15~3813
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=68d4138204b09b658506e8eefa231c985b8f5363;p=thirdparty%2Fgcc.git

libgcov: Call __builtin_fork instead of fork

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): Use __builtin_fork instead
	of fork.
