Subject: c++: Function declared with typedef with eh-specification.
X-Git-Tag: releases/gcc-9.3.0~176
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9d4d55a52d44b11e7621a5b455f2a38a32b37367;p=thirdparty%2Fgcc.git

c++: Function declared with typedef with eh-specification.

We just need to handle the exception specification like other properties of
a function typedef.

	PR c++/90731
	* decl.c (grokdeclarator): Propagate eh spec from typedef.
