Aaron Ballman	7de7161304	Use functions with prototypes when appropriate; NFC ... A significant number of our tests in C accidentally use functions without prototypes. This patch converts the function signatures to have a prototype for the situations where the test is not specific to K&R C declarations. e.g., void func(); becomes void func(void); This is the sixth batch of tests being updated (there are a significant number of other tests left to be updated).	2022-02-09 17:16:10 -05:00
John McCall	8376037861	In Objective-C, ignore attempts to redefine the ARC/GC qualifier macros. ... This works around existing system headers which unconditionally redefine these macros. This is reasonably safe to do because we used to warn about it anyway (outside of system headers). Continue to warn if the redefinition would have changed the expansion. Still permit redefinition if the macro is explicitly #undef'ed first. rdar://23788307 llvm-svn: 255311	2015-12-10 23:31:01 +00:00
