* PR23942: a pure-specifier's integer literal must be spelled '0'Richard Smith2015-06-291-0/+10
| | | | llvm-svn: 241019
* Add a new error for unexpected semi-colon before closing delimiter.Richard Trieu2015-05-121-3/+3
| | | | | | | | | Previously, if a semi-colon is unexpectedly added before a closing ')', ']' or '}', two errors and one note would emitted, and the parsing would get confused to which scope it was in. This change consumes the semi-colon, recovers parsing better, and emits only one error with a fix-it. llvm-svn: 237192

* Follow-up to r217302: Don't crash on ~A::A in a postfix expr suffix followed ↵Nico Weber2015-02-021-0/+5
| | | | | | | | | | | | | | | | | by '<'. This used to crash, complaining "ObjectType and scope specifier cannot coexist": struct A { } b = b.~A::A <int>; The only other caller of ParseOptionalCXXScopeSpecifier() that passes in a non-empty ObjectType clears the ObjectType of the scope specifier comes back non-empty (see the tok::period case in Parser::ParsePostfixExpressionSuffix()), so do that here too. Found by SLi's bot. llvm-svn: 227781
* Follow-up to r217302 and r227555: Don't crash on inline ~A::A() if A is an int.Nico Weber2015-01-301-0/+15
| | | | | | | | | | | | | | | | | | | Even with r227555, this still crashed: struct S { int A; ~A::A() {} }; That's because ParseOptionalCXXScopeSpecifier()'s call to ActOnCXXNestedNameSpecifier() doesn't mark the scope spec as invalid if sema thought it's a good idea to fixit-correct "::" to ":". For the diagnostic improvement done in r217302, we never want :: to be interpreted as :, so fix this by setting ColonSacred to false temporarily. Found by SLi's bot. llvm-svn: 227581

| | | | | | | | scope to -Wc++11-extensions. Move extra semicolon after member function definition diagnostic out of -pedantic, since C++ allows a single semicolon there. Keep it in -Wextra-semi, though, since it's still questionable. llvm-svn: 160618
* Move the warnings for extra semi-colons under -Wextra-semi. Also, addedRichard Trieu2012-05-161-2/+2

| | | | | | | | | | | | | constructor, but X is not a known typename, check whether the tokens could possibly match the syntax of a declarator before concluding that it isn't a constructor. If it's definitely ill-formed, assume it is a constructor. Empirical evidence suggests that this pattern is much more often a constructor with a typoed (or not-yet-declared) type name than any of the other possibilities, so the extra cost of the check is not expected to be problematic. llvm-svn: 153488

* Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.Daniel Dunbar2009-12-151-1/+1
| | | | | | | | | - 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). llvm-svn: 91446

| | | | | | | | | | | | | | | redeclarations. For example, checks that a class template redeclaration has the same template parameters as previous declarations. Detangled class-template checking from ActOnTag, whose logic was getting rather convoluted because it tried to handle C, C++, and C++ template semantics in one shot. Made some inroads toward eliminating extraneous "declaration does not declare anything" errors by adding an "error" type specifier. llvm-svn: 63973
* Implement support for anonymous structs and unions in C. Both C andDouglas Gregor2009-01-121-1/+1

Addresses several bugs: <rdar://problem/6259534> <rdar://problem/6481130> <rdar://problem/6483159> The test case in PR clang/1750 now passes with -fsyntax-only, but CodeGen for inline assembler still fails. llvm-svn: 62112
