2012-07-19For varargs, diagnose passing ObjC objects by value like other non-POD types.Jordan Rose
While we still want to consider this a hard error (non-POD variadic args are normally a DefaultError warning), delaying the diagnostic allows us to give better error messages, which also match the usual non-POD errors more closely. In addition, this change improves the diagnostic messages for format string argument type mismatches by passing down the type of the callee, so we can say "variadic method" or "variadic function" appropriately. <rdar://problem/11825593> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160517 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-06Added a new attribute, objc_root_class, which informs the compiler when a ↵Patrick Beard
root class is intentionally declared. The warning this inhibits, -Wobjc-root-class, is opt-in for now. However, all clang unit tests that would trigger the warning have been updated to use -Wno-objc-root-class. <rdar://problem/7446698> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154187 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-15Modify how the -verify flag works. Currently, the verification string andRichard Trieu
diagnostic message are compared. If either is a substring of the other, then no error is given. This gives rise to an unexpected case: // expect-error{{candidate function has different number of parameters}} will match the following error messages from Clang: candidate function has different number of parameters (expected 1 but has 2) candidate function has different number of parameters It will also match these other error messages: candidate function function has different number of parameters number of parameters This patch will change so that the verification string must be a substring of the diagnostic message before accepting. Also, all the failing tests from this change have been corrected. Some stats from this cleanup: 87 - removed extra spaces around verification strings 70 - wording updates to diagnostics 40 - extra leading or trailing characters (typos, unmatched parens or quotes) 35 - diagnostic level was included (error:, warning:, or note:) 18 - flag name put in the warning (-Wprotocol) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146619 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-15Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.Daniel Dunbar
- This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91446 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-03This patch does the following.Fariborz Jahanian
1) Issue digsnostics in non-fragile ABI, when an expression evaluates to an interface type (except when it is used to access a non-fragile ivar). 2) Issue unsupported error in fragile ABI when an expression evaluates to an interface type (except when it is used to access a fragile ivar). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80860 91177308-0d34-0410-b5e6-96231b3b80d8
