X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cd33509357a897aa5fe3ef2fb6be984ad57df418;p=thirdparty%2Fgcc.git

Fix MIPS bootstrap

gcc/ChangeLog:
	Fix bootstap on mips
	* dwarf2out.c (is_naming_typedef_dec): Built-in TYPE_DECLs cannot
	be naming typedefs.

gcc/testsuite/ChangeLog:
	Fix MIPS bootstrap
	* g++.dg/other/typedef4.C: New test.
