* Partially revert r186903.Eli Friedman2013-07-261-1/+1
| | | | | | | | It turns out that Plum Hall depends on us not emitting an error on integer literals which fit into long long, but fit into unsigned long long. So C99 conformance requires not conforming to C99. :) llvm-svn: 187172
* Integers which are too large should be an error.Eli Friedman2013-07-231-4/+4
| | | | | | | | Switch some warnings over to errors which should never have been warnings in the first place. (Also, a minor fix to the preprocessor rules for integer literals while I'm here.) llvm-svn: 186903
* Add SourceRange to PPCallbacks::Defined callback.John Thompson2013-07-191-9/+14

* [Preprocessor/Modules] Separate the macro directives kinds into their own ↵Argyrios Kyrtzidis2013-03-261-1/+1
| | | | | | | | | | | | | | | | MacroDirective's subclasses. For each macro directive (define, undefine, visibility) have a separate object that gets chained to the macro directive history. This has several benefits: -No need to mutate a MacroDirective when there is a undefine/visibility directive. Stuff like PPMutationListener become unnecessary. -No need to keep extra source locations for the undef/visibility locations for the define directive object (which is the majority of the directives) -Much easier to hide/unhide a section in the macro directive history. -Easier to track the effects of the directives across different submodules. llvm-svn: 178037
* PR15539: Record "evaluating if/elif condition" flag in the right placeDavid Blaikie2013-03-181-0/+2
| | | | | | | The previous implementation missed the case where the elif condition was evaluated from the context of an #ifdef that was false causing PR15539. llvm-svn: 177345

* Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth2012-12-041-3/+3
| | | | | | | | | | | | | uncovered. This required manually correcting all of the incorrect main-module headers I could find, and running the new llvm/utils/sort_includes.py script over the files. I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. llvm-svn: 169237
* Change the wording of the extension warning fromDmitri Gribenko2012-09-241-4/+9
| | | | | | | | | > 'long long' is an extension when C99 mode is not enabled to > 'long long' is a C++11 extension while compiling in C++98 mode. llvm-svn: 164545
* Small cleanup of literal semantic analysis: hiding 'char *' pointers behindDmitri Gribenko2012-09-241-2/+1
| | | | | | | StringRef makes code cleaner. Also, make the temporary buffer smaller: 512 characters is unreasonably large for integer literals. llvm-svn: 164484
* The keywords "true" and "false" shouldn't warn under -Wundef.Eli Friedman2012-09-201-1/+3
| | | | llvm-svn: 164279
* Unify naming of LangOptions variable/get function across the Clang stack ↵David Blaikie2012-03-111-4/+4
| | | | | | | | | | (Lex to AST). The member variable is always "LangOpts" and the member function is always "getLangOpts". Reviewed by Chris Lattner llvm-svn: 152536
* Add support for cooked forms of user-defined-integer-literal andRichard Smith2012-03-081-1/+5
| | | | | | | user-defined-floating-literal. Support for raw forms of these literals to follow. llvm-svn: 152302
* User-defined literals: reject string and character UDLs in all places where theRichard Smith2012-03-061-0/+4
| | | | | | | | | | grammar requires a string-literal and not a user-defined-string-literal. The two constructs are still represented by the same TokenKind, in order to prevent a combinatorial explosion of different kinds of token. A flag on Token tracks whether a ud-suffix is present, in order to prevent clients from needing to look at the token's spelling. llvm-svn: 152098
* Basic: import SmallString<> into clang namespaceDylan Noblesmith2012-02-051-2/+2
| | | | | | | (I was going to fix the TODO about DenseMap too, but that would break self-host right now. See PR11922.) llvm-svn: 149799

* -Wc++98-compat warnings for the lexer.Richard Smith2011-10-151-4/+3
| | | | | | | | This also adds a -Wc++98-compat-pedantic for warning on constructs which would be diagnosed by -std=c++98 -pedantic (that is, it warns even on C++11 features which we enable by default, with no warning, in C++98 mode). llvm-svn: 142034

* Support code-completion for C++ inline methods and ObjC buffering methods.Argyrios Kyrtzidis2011-09-041-0/+2
| | | | | | | | | | | | | | Previously we would cut off the source file buffer at the code-completion point; this impeded code-completion inside C++ inline methods and, recently, with buffering ObjC methods. Have the code-completion inserted into the source buffer so that it can be buffered along with a method body. When we actually hit the code-completion point the cut-off lexing or parsing. Fixes rdar://10056932&8319466 llvm-svn: 139086
* A couple fixes for preprocessor expressions:Eli Friedman2011-08-031-9/+13
| | | | | | | | | | | 1. Be more tolerant of comments in -CC (comment-preserving) mode. We were missing a few cases. 2. Make sure to expand the second FOO in "#if defined FOO FOO". (See also r97253, which addressed the case of "#if defined(FOO FOO".) Fixes PR10286. llvm-svn: 136748

* Rename tok::eom to tok::eod.Peter Collingbourne2011-02-281-9/+9
| | | | | | | | The previous name was inaccurate as this token in fact appears at the end of every preprocessing directive, not just macro definitions. No functionality change, except for a diagnostic tweak. llvm-svn: 126631
* Fix diagnostic pragmas.Argyrios Kyrtzidis2010-12-151-1/+1
| | | | | | | | | | | | Diagnostic pragmas are broken because we don't keep track of the diagnostic state changes and we only check the current/latest state. Problems manifest if a diagnostic is emitted for a source line that has different diagnostic state than the current state; this can affect a lot of places, like C++ inline methods, template instantiations, the lexer, etc. Fix the issue by having the Diagnostic object keep track of the source location of the pragmas so that it is able to know what is the diagnostic state at any given source location.

Use the Invalid parameters in the literal parsers (string, floating point, integral, character) to make them robust against errors that stem from, e.g., PCH files that are not consistent with the underlying file system. I still need to audit every use caller to all of these routines, to determine which ones need specific handling of error conditions. llvm-svn: 98608
