2012-01-09Extend the diagnostic for a ',' at the end of a declaration where a ';' wasRichard Smith
intended to cover C++ class definitions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147808 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-25Fix constexpr handling to allow 'extern constexpr' variable declarations. We noRichard Smith
longer have access to the source locations we need to produce the 'replace constexpr with const' fixits, so they're gone for now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147273 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
2011-11-30Revert most of r145372 for now. Lookahead beyond the ';' in a functionRichard Smith
declaration tickles a bug in the way we handle visibility pragmas. The improvement to error recovery for template function definitions declared with the 'typedef' specifier in r145372 is unrelated and not reverted here. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145541 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-29Add fix-it to remove 'typedef' from function template definitions. Such a tokenRichard Smith
was probably meant to be 'typename', which we will have already suggested if it is appropriate. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145395 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-29PR10101: Recover better from a common copy-paste error: if a functionRichard Smith
declaration at namespace scope is followed by a semicolon and an open-brace (or in C++, a 'try', ':' or '='), then the error is probably a function definition with a spurious ';', rather than a mysterious '{'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145372 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-20Make the -verify bits in this test actually test something, and fix a few casesRichard Smith

2011-10-19Improve the diagnostic when a comma ends up at the end of a declarator groupRichard Smith
instead of a semicolon (as sometimes happens during refactorings). When such a comma is seen at the end of a line, and is followed by something which can't possibly be a declarator (or even something which might be a plausible typo for a declarator), suggest that a semicolon was intended. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142544 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-11Catch placeholder types in DefaultLvalueConversionJohn McCall
and DefaultFunctionArrayLvalueConversion. To prevent significant regression for should-this-be-a-call fixits, and to repair some such regression from the introduction of bound member placeholders, make those placeholder checks try to build calls appropriately. Harden the build-a-call logic while we're at it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141738 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-02Make -fobjc-nonfragile-abi the -cc1 default, since it's theJohn McCall
increasingly prevailing case to the point that new features like ARC don't even support the fragile ABI anymore. This required a little bit of reshuffling with exceptions because a check was assuming that ObjCNonFragileABI was only being set in ObjC mode, and that's actually a bit obnoxious to do. Most, though, it involved a perl script to translate a ton of test cases. Mostly no functionality change for driver users, although there are corner cases with disabling language-specific exceptions that we should handle more correctly now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140957 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-29constexpr: semantic checking for constexpr variables.Richard Smith
We had an extension which allowed const static class members of floating-point type to have in-class initializers, 'as a C++0x extension'. However, C++0x does not allow this. The extension has been kept, and extended to all literal types in C++0x mode (with a fixit to add the 'constexpr' specifier). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140801 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-27Extend Sema::ClassifyName() to support C++, ironing out a few issuesDouglas Gregor
in the classification of template names and using declarations. We now properly typo-correct the leading identifiers in statements to types, templates, values, etc. As an added bonus, this reduces the number of lookups required for disambiguation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130288 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-27Improve diagnostics for typo correction via Sema::ClassifyName(), byDouglas Gregor
looking at the context and the correction and using a custom diagnostic. Also, enable some Fix-It tests that were somewhat lamely disabled. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130283 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-24Implement a new identifier-classification scheme where SemaDouglas Gregor
performs name lookup for an identifier and resolves it to a type/expression/template/etc. in the same step. This scheme is intended to improve both performance (by reducing the number of redundant name lookups for a given identifier token) and error recovery (by giving Sema a chance to correct type names before the parser has decided that the identifier isn't a type name). For example, this allows us to properly typo-correct type names at the beginning of a statement: t.c:6:3: error: use of undeclared identifier 'integer'; did you mean 'Integer'? integer *i = 0; ^~~~~~~ Integer t.c:1:13: note: 'Integer' declared here typedef int Integer; ^ Previously, we wouldn't give a Fix-It because the typo correction occurred after the parser had checked whether "integer" was a type name (via Sema::getTypeName(), which isn't allowed to typo-correct) and therefore decided to parse "integer * i = 0" as an expression. By typo-correcting earlier, we typo-correct to the type name Integer and parse this as a declaration. Moreover, in this context, we can also typo-correct identifiers to keywords, e.g., t.c:7:3: error: use of undeclared identifier 'vid'; did you mean 'void'? vid *p = i; ^~~ void and recover appropriately. Note that this is very much a work-in-progress. The new Sema::ClassifyName is only used for expression-or-declaration disambiguation in C at the statement level. The next steps will be to make this work for the same disambiguation in C++ (where functional-style casts make some trouble), then push it further into the parser to eliminate more redundant name lookups. Fixes <rdar://problem/7963833> for C and starts us down the path of <rdar://problem/8172000>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130082 91177308-0d34-0410-b5e6-96231b3b80d8
