Subject: OpenMP: Silence uninitialized variable warning in C++ front end.
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=a9f1e49fa11de85cdc55ee22ea3c021157e07719;p=thirdparty%2Fgcc.git

OpenMP: Silence uninitialized variable warning in C++ front end.

There's no actual problem with the code here, just a false-positive
warning emitted by some older GCC versions.

gcc/cp/ChangeLog
	* parser.cc (cp_finish_omp_declare_variant): Initialize
	append_args_last.

(cherry picked from commit c978965b445079abbb88c22ba74de1e26e9f5b81)
