// RUN: %clang_cc1 -fsyntax-only -verify -Wattributes %s

int x __attribute__((foobar)); // expected-warning {{unknown attribute 'foobar' ignored}}
void z(void) __attribute__((bogusattr)); // expected-warning {{unknown attribute 'bogusattr' ignored}}
Rename -Wunknown-attributes to -Wattributes to match GCC. llvm-svn: 132422 2011-06-01 20:09:40 +00:00			`// RUN: %clang_cc1 -fsyntax-only -verify -Wattributes %s`
Add support for differentiating between attributes ignored when handled and unknown attributes that we discard. Add a diagnostic group for unknown attribute warnings to allow turning these off when we don't care. Also consolidates the tests for this case. llvm-svn: 107864 2010-07-08 09:42:26 +00:00

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 first batch of tests being updated (there are a significant number of other tests left to be updated). 2022-02-03 16:39:21 -05:00			`void z(void) __attribute__((bogusattr)); // expected-warning {{unknown attribute 'bogusattr' ignored}}`
