2008-05-05Neil pointed out that clang doesn't generate ranges from diagnosticsChris Lattner
related to pp-expressions. Doing so is pretty simple and this patch implements it, yielding nice diagnostics like: t.c:2:7: error: division by zero in preprocessor expression #if 1 / (0 + 0) ~ ^ ~~~~~~~ t.c:5:14: error: expected ')' in preprocessor expression #if (412 + 42 ~~~~~~~~^ t.c:5:5: error: to match this '(' #if (412 + 42 ^ t.c:10:10: warning: left side of operator converted from negative value to unsigned: -42 to 18446744073709551574 #if (-42 + 0U) / -2 ~~~ ^ ~~ t.c:10:16: warning: right side of operator converted from negative value to unsigned: -2 to 18446744073709551614 #if (-42 + 0U) / -2 ~~~~~~~~~~ ^ ~~ 5 diagnostics generated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50638 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-17class Preprocessor: Now owns the "predefines" char*; it deletes [] it in its ↵Ted Kremenek
dstor. clang.cpp: InitializePreprocessor now makes a copy of the contents of PredefinesBuffer and passes it to the preprocessor object. clang.cpp: DriverPreprocessorFactory now calls "InitializePreprocessor" instead of this being done in main(). html::HighlightMacros() now takes a PreprocessorFactory, allowing it to conjure up a new Preprocessor to highlight macros. class HTMLDiagnostics now takes a PreprocessorFactory* that it can use for html::HighlightMacros(). Updated clients of HTMLDiagnostics to use this new interface. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49875 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-10implement simple support for arbitrary token lookahead. Change the Chris Lattner
objc @try parser to use it, fixing a FIXME. Update the objc-try-catch-1.m file to pass now that we get more reasonable errors. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48129 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-09rename the MacroExpander class to TokenLexer. It handles bothChris Lattner
token streams and macro lexing, so a more generic name is useful. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48071 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-09rename MacroTokens -> Tokens. When this is a token stream, there is no macroChris Lattner
involved. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48070 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-05Remove the first layer of support for "portability" warnings. This is Chris Lattner
theoretically useful, but not useful in practice. It adds a bunch of complexity, and not much value. It's best to nuke it. One big advantage is that it means the target interfaces will soon lose their SLoc arguments and target queries can never emit diagnostics anymore (yay). Removing this also simplifies some of the core preprocessor which should make it slightly faster. Ted, I didn't simplify TripleProcessor, which can now have at most one triple, and can probably just be removed. Please poke at it when you have time. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47930 91177308-0d34-0410-b5e6-96231b3b80d8

2008-02-24Two more Windows-related fixes:Ted Kremenek
- More enum signeness bitfield fixes (MSVC treats enums as signed). - Fixed in Lex/HeaderSearch.cpp an unsafe copy between two HeaderSearch::PerFileInfo entries in a common vector. The copy involved two calls to getFileInfo() within the assignment; these calls could have side-effects that enlarged the internal vector, and with MSVC this would invalidate one of the values in the assignment. Patch by Argiris Kirtzidis! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47536 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-23Change encoding of TokenKind in IdentifierTable to be of type "unsigned"Ted Kremenek
instead of TokenKind because of signedness issues with MSVC and enums. Patch from Argiris Kirtzidis. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47515 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-07Implement support for the extremely atrocious MS /##/ extension, Chris Lattner
which pastes together a comment. This is only enabled with -fms-extensions of course. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46845 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-02Cleanup previous patch (based on feedback from Ted).Steve Naroff
Since this behavior is useful for most classes, we might consider adding a simple 3 method class that implements the behavior. Ted said that Boost has such a class. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46654 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-01Make sure SourceManager/HeaderSearch don't support default copy constructors ↵Steve Naroff
(since they result in bad runtime behavior). I'm sure there are other classes that might need this "guard", however I was bitten by these 2 recently (so I thought I'd fix them). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46653 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-07Fix a nasty corner case that Neil noticed in PR1900, where we would Chris Lattner
incorrectly apply the multiple include optimization to files with guards like: #if !defined(x) MACRO where MACRO could expand to different things in different contexts. Thanks Neil! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45716 91177308-0d34-0410-b5e6-96231b3b80d8

2007-12-19Interned MainFileID within SourceManager. Since SourceManager is referenced byTed Kremenek
both Preprocessor and ASTContext, we no longer need to explicitly pass MainFileID around in function calls that also pass either Preprocessor or ASTContext. This resulted in some nice cleanups in the ASTConsumers and the driver. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45228 91177308-0d34-0410-b5e6-96231b3b80d8

2007-12-17implement enough helper functions to successfully dump out the Chris Lattner
contents of the header map. Look ma, no assumptions about input data here (aka, corrupt header maps can't crash the compiler - crazy thought). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45122 91177308-0d34-0410-b5e6-96231b3b80d8

2007-12-17refactor an better comment framework lookup code. This moves it from Chris Lattner
HeaderSearch into DirectoryLookup, as a particular framework lookup is specific to the directory we are currently querying. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45093 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-17as it turns out, frameworks and headermaps are orthogonal. Make this so inChris Lattner

2007-11-26Added optional pass-by-reference argument "isExact" toTed Kremenek
NumericLiteralParser::GetFloatValue(). Upon method return, this flag has the value true if the returned APFloat can exactly represent the number in the parsed text, and false otherwise. Modified the implementation of GetFloatValue() to parse literals using APFloat's convertFromString method (which allows us to set the value of isExact). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44339 91177308-0d34-0410-b5e6-96231b3b80d8
