Dmitri Gribenko	56fde96610	gnu-flags.c test: relax the check a bit ... This tests warning flags, so no need to test for specific alignment which is platform-dependent. llvm-svn: 188993	2013-08-22 08:13:43 +00:00
Richard Sandiford	4633cd7b08	Tweak gnu-flags.c test for z, where globals have 2-byte alignment by default ... llvm-svn: 188905	2013-08-21 16:37:37 +00:00
Eli Friedman	85698c8d7b	Remove Extension warning for GNU local labels. ... We generally don't warn about extensions involving keywords reserved for the implementation, so we shouldn't warn here either: the standard doesn't require it, and it doesn't provide useful information to the user. llvm-svn: 188840	2013-08-20 22:44:32 +00:00
Eli Friedman	571c3ae7d6	Add more specific flags for misc GNU extensions. ... This adds the following as subgroups of -Wgnu: -Wgnu-alignof-expression, -Wgnu-case-range, -Wgnu-complex-integer, -Wgnu-conditional-omitted-operand, -Wgnu-empty-initializer, -Wgnu-label-as-value, -Wgnu-local-label, and -Wgnu-statement-expression, Patch by Peter Lewis. llvm-svn: 188839	2013-08-20 22:44:28 +00:00
