X-Git-Tag: releases/gcc-12.5.0~347
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9d2f4c8b0f849839ff1b9b7d5f9e734271c03634;p=thirdparty%2Fgcc.git

c++: Allow pragmas in NSDMIs [PR118147]

This patch removes the (unnecessary) CPP_PRAGMA_EOL case from
cp_parser_cache_defarg, which currently has the result that any pragmas
in the NSDMI cause an error.

	PR c++/118147

gcc/cp/ChangeLog:

	* parser.cc (cp_parser_cache_defarg): Don't error when
	CPP_PRAGMA_EOL.

gcc/testsuite/ChangeLog:

	* g++.dg/cpp0x/nsdmi-defer7.C: New test.
