* [PowerPC]To provide better compatibility with gcc I added the __bool keyword ↵Bill Seurer2015-01-122-0/+6
| | | | | | | | | | | | | | | | | to the Alitivec support in clang. __bool is functionally identical to using bool when declaring vector types. For example: vector bool char v_bc; vector __bool char v___bc; clang already supported vector/__vector and pixel/__pixel but was missing __bool. http://llvm.org/bugs/show_bug.cgi?id=19220 For reference: https://gcc.gnu.org/onlinedocs/gcc-4.9.2/gcc/PowerPC-AltiVec_002fVSX-Built-in-Functions.html http://reviews.llvm.org/D6882 llvm-svn: 225664
* Parse: Get rid of cxx_exceptspec_end, use EOF insteadDavid Majnemer2015-01-122-3/+7
| | | | | | | | Similar to r225619, use a special EOF token to mark the end of the exception specification instead of cxx_exceptspec_end. Use the current scope as the marker. llvm-svn: 225622
* Parse: Just a small tidy-up in ParseLexedMethodDeclarationDavid Majnemer2015-01-121-5/+7
| | | | | | No functional change intended, just tidy up the parse flow. llvm-svn: 225620
* Parse: Get rid of tok::cxx_defaultarg_end, use EOF insteadDavid Majnemer2015-01-123-8/+9
| | | | | | | I added setEofData/getEofData to solve this sort of problem back in r224505. Use the Param's decl to tell us if this is *our* EOF token. llvm-svn: 225619
* Parse: It's cleaner to handle cxx_defaultarg_end in SkipUntil directlyDavid Majnemer2015-01-123-11/+9
| | | | llvm-svn: 225616
* Parse: Don't let BalancedDelimiterTracker consume cxx_defaultarg_endDavid Majnemer2015-01-121-1/+1
| | | | | | | | It is not correct to let it consume the cxx_defaultarg_end token. I'm starting to wonder if it makes more sense to stop SkipUntil from consuming such tokens. llvm-svn: 225615
* Parse: Don't parse beyond the end of the synthetic default argument tokDavid Majnemer2015-01-121-3/+10
| | | | | | | | Recovery from malformed lambda introducers would find us consuming the synthetic default argument token, which is bad. Instead, stop right before that token. llvm-svn: 225613
* Parse: Don't crash when an annotation token shows up in a C++11 attrDavid Majnemer2015-01-091-3/+5
| | | | | | | It's not safe to blindly call getIdentifierInfo without checking the token is not an annotation token. llvm-svn: 225533
* Parse: Don't crash when namespace is in GNU statement exprDavid Majnemer2015-01-091-8/+13
| | | | | | | | | | | Parser::ParseNamespace can get a little confused when it found itself inside a compound statement inside of a non-static data member initializer. Try to determine that the statement expression's scope makes sense before trying to parse it's contents. llvm-svn: 225514
* Parse: Don't crash when trailing return type is missingDavid Majnemer2015-01-091-5/+4
| | | | | | | | | Sema::CheckParmsForFunctionDef can't cope with a null TypeSourceInfo. Don't let the AST contain the malformed lambda. This fixes PR22122. llvm-svn: 225505
* Fix indentation. No behavior change.Nico Weber2015-01-041-1/+1
| | | | llvm-svn: 225129
* Wrap to 80 columns, no behavior change.Nico Weber2015-01-041-4/+5
| | | | llvm-svn: 225122
* Parse: __attribute__((keyword)) shouldn't errorDavid Majnemer2015-01-031-3/+4
| | | | | | | Weird constructs like __attribute__((inline)) or __attibute__((typename)) should result in warnings, not errors. llvm-svn: 225118
* Fix build breakageDavid Majnemer2014-12-291-1/+2
| | | | | | That's what I get for last second changes... llvm-svn: 224967
* Parse: Recover more gracefully from extra :: tokens before a {David Majnemer2014-12-291-1/+11
| | | | | | | Instead of crashing, recover by eating the extra trailing scope qualifier. This means we will treat 'struct A:: {' as 'struct A {'. llvm-svn: 224966
* Crash even less on malformed attributes in an incorrect location.Nico Weber2014-12-291-1/+4
| | | | | | | | | | | This is a follow-up to r224915. This adds a bit more line noise to the tests added in that revision to make sure the parser is ready for a toplevel decl after each incorrect line. Use this to move the tests up to where they belong. This uncovered that the early return was missing a call to ActOnTagDefinitionError(), so add that. (Also fixes at least one of the crashes on SLi's bot.) llvm-svn: 224958
* Parse: Ignore '::' in 'struct :: {'David Majnemer2014-12-291-5/+11
| | | | | | | Let's pretend that we didn't see the '::' instead of go on believing that we've got some anonymous, but globally qualified, struct. llvm-svn: 224945
* Don't crash on malformed attributes in an incorrect location.Nico Weber2014-12-291-0/+10
| | | | | | | | | | | | | | | | | | r168626 added nicer diagnostics for attributes in the wrong places, such as after the `final` on a class. To do this, it added code that did high-level pattern matching for e.g. 'final' 'alignas' '(' and then skipped until the closing ')'. If it saw that, it then went down the regular class parsing path and then called MaybeParseCXX11Attributes() to parse the attribute after the 'final' using real attribute parsing code. On invalid attributes, the real attribute parsing code could eat more tokens than the pattern matching code and for example skip past the '{' starting the class, which would then lead to an assert. To prevent this, check for a good state after calling MaybeParseCXX11Attributes() (which morphed into CheckMisplacedCXX11Attribute() in r175575) and bail out if things look bleak. Found by SLi's afl bot. llvm-svn: 224915
* SemaCXX: Don't crash when annotation tokens show up before the tag nameDavid Majnemer2014-12-291-1/+2
| | | | | | | | Clang has a hack to accept definitions of structs with tag names which have the same name as intrinsics. However, this hack didn't guard against annotation tokens showing up in the token stream. llvm-svn: 224909
* Don't crash on surprising tokens in default parameter template lists.Nico Weber2014-12-282-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | Fixes this snippet from SLi's afl fuzzer output: class { i (x = <, enum This parsed i as a function, x as a paramter, and the stuff after < as a template list. This then called TryConsumeDeclarationSpecifier() which called TryAnnotateCXXScopeToken() without checking the preconditions of this function. Check them before calling, like all other callers of TryAnnotateCXXScopeToken() do. A more readable reproducer that causes the same crash is class { void i(int x = MyTemplateClass<int, union int>::foo()); }; The reduced version used an eof token as surprising token, but kw_int works just as well to repro and is easier to insert into a test file. llvm-svn: 224906
* Parse: Don't crash when 'typename' shows up in an attributeDavid Majnemer2014-12-281-1/+2
| | | | | | | | | isDeclarationSpecifier performs error recovers which jostles the token stream. Specifically, TryAnnotateTypeOrScopeToken will end up consuming a typename token which will confuse the attribute parsing machinery as we no-longer have something identifier-like. llvm-svn: 224903

* Parse: Don't parse after the eof has been consumedDavid Majnemer2014-12-181-1/+4
| | | | | | | | | | | | | | ParseCXXNonStaticMemberInitializer stashes away all the tokens for the initializer and an additional EOF token to denote where the initializer ends. However, it is possible for ParseLexedMemberInitializer to get its hands on the "real" EOF token; since the two tokens are indistinguishable, we end up consuming the EOF and descend into madness. Instead, make it possible to tell which EOF token we are looking at. This fixes PR21872. llvm-svn: 224505
* Rangify for loop, NFC.Yaron Keren2014-12-171-4/+2

* Parse: Consume tokens more carefully in CheckForLParenAfterColonColonDavid Majnemer2014-12-171-27/+29
| | | | | | | | | We would consume the lparen even if it wasn't followed by an identifier or a star-identifier pair. This fixes PR21815. llvm-svn: 224403
* Diagnose function template definitions inside functionsReid Kleckner2014-12-153-4/+16
| | | | | | | | | | | | | | | The parser can only be tricked into parsing a function template definition by inserting a typename keyword before the function template declaration. This used to make us crash, and now it's fixed. While here, remove an unneeded boolean parameter from ParseDeclGroup. This boolean always corresponded to non-typedef declarators at file scope. ParseDeclGroup already has precise diagnostics for the function definition typedef case, so we can let that through. Fixes PR21839. llvm-svn: 224287
* Parse: MS property members cannot have an in-class initializerDavid Majnemer2014-12-131-1/+4
| | | | | | | | | We would crash trying to treat a property member as a field. These shoudl be forbidden anyway, reject programs which contain them. This fixes PR21840. llvm-svn: 224193
* Fix two small bugs in typo correction. One assertion failure building member ↵Nick Lewycky2014-12-131-0/+2
| | | | | | | | expressions because the lookup finds a different name than the original, fixed by updating the LookupResult's name with the name of the found decl. Second is that we also diagnose delayed typo exprs in the index of an array subscript expression. The testcase shows a third bug with a FIXME in it. llvm-svn: 224183
* Parse: Concatenated string literals should be verified in inline asmDavid Majnemer2014-12-111-16/+13
| | | | | | | | | | While we would correctly handle asm("foo") and reject asm(L"bar"), we weren't careful to handle cases where an ascii literal could be concatenated with a wide literal. This fixes PR21822. llvm-svn: 223992
* Modified the Objective-C lexer and parser (only Sean Callanan2014-12-091-2/+8
| | | | | | | | | | | | | | | | in debugger mode) to accept @import declarations and pass them to the debugger. In the preprocessor, accept import declarations if the debugger is enabled, but don't actually load the module, just pass the import path on to the preprocessor callbacks. In the Objective-C parser, if it sees an import declaration in statement context (usual for LLDB), ignore it and return a NullStmt. llvm-svn: 223855
