git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67802 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-26- Minor change to dump of ivar layout map.Fariborz Jahanian
- Temporarily undef'ed __OBJC2__ in nonfragile objc abi mode as it was forcing ivar synthesis in a certain project which clang does not yet support. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67766 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-24change the __VERSION__ string to be more sensible. It would be useful to ↵Chris Lattner
include the clang version # too. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67619 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-18Fix some issues handling sub-token locations that come from macro expansions.Chris Lattner
We now emit: t.m:6:15: warning: field width should have type 'int', but argument has type 'unsigned int' printf(STR, (unsigned) 1, 1); ^ ~~~~~~~~~~~~ t.m:3:18: note: instantiated from: #define STR "abc%*ddef" ^ which has the correct location in the string literal in the note line. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64936 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-15track "just a little more" location information for macro instantiations.Chris Lattner
Now instead of just tracking the expansion history, also track the full range of the macro that got replaced. For object-like macros, this doesn't change anything. For _Pragma and function-like macros, this means we track the locations of the ')'. This is required for PR3579 because apparently GCC uses the line of the ')' of a function-like macro as the location to expand __LINE__ to. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64601 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-13Give TargetInfo a new IntPtrType to hold the intptr_t type forChris Lattner
a target. Make Preprocessor.cpp define a new __INTPTR_TYPE__ macro based on this. On linux/32, set intptr_t to int, instead of long. This fixes PR3563. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64495 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-13Fix rdar://6562329, a static analyzer crash Ted noticed on Chris Lattner
wine sources. This was happening because HighlightMacros was calling EnterMainFile multiple times on the same preprocessor object and getting an assert due to the new #line stuff (the file in question was bison output with #line directives). The fix for this is to not reenter the file. Instead, relex the tokens in raw mode, swizzle them a bit and repreprocess the token stream. An added bonus of this is that rewrite macros will now hilight the macro definition as well as its uses. Woo. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64480 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-12PTH: Cache stat information for files in the PTH file. Hook up FileManagerTed Kremenek
to use this stat information in the PTH file using a 'StatSysCallCache' object. Performance impact (Cocoa.h, PTH): - number of stat calls reduces from 1230 to 425 - fsyntax-only: time improves by 4.2% We can reduce the number of stat calls to almost zero by caching negative stat calls and directory stat calls in the PTH file as well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64353 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-29move library-specific diagnostic headers into library private dirs. ReduceChris Lattner

2009-01-27Split the single monolithic DiagnosticKinds.def file into oneChris Lattner
.def file for each library. This means that adding a diagnostic to sema doesn't require all the other libraries to be rebuilt. Patch by Anders Johnsen! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63111 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-27Introduce a new PresumedLoc class to represent the concept of a locationChris Lattner
as reported to the user and as manipulated by #line. This is what __FILE__, __INCLUDE_LEVEL__, diagnostics and other things should follow (but not dependency generation!). This patch also includes several cleanups along the way: - SourceLocation now has a dump method, and several other places that did similar things now use it. - I cleaned up some code in AnalysisConsumer, but it should probably be simplified further now that NamedDecl is better. - TextDiagnosticPrinter is now simplified and cleaned up a bit. This patch is a prerequisite for #line, but does not actually provide any #line functionality. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63098 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-27PTH: Use Token::setLiteralData() to directly store a pointer to cached ↵Ted Kremenek
spelling data in the PTH file. This removes a ton of code for looking up spellings using sourcelocations in the PTH file. This simplifies both PTH-generation and reading. Performance impact for -fsyntax-only on Cocoa.h (with Cocoa.h in the PTH file): - PTH generation time improves by 5% - PTH reading improves by 0.3%. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63072 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-26This change refactors some of the low-level lexer interfaces a bit.Chris Lattner
Token now has a class of kinds for "literals", which include numeric constants, strings, etc. These tokens can optionally have a pointer to the start of the token in the lexer buffer. This makes it faster to get spelling and do other gymnastics, because we don't have to go through source locations. This change is performance neutral, but will make other changes more feasible down the road. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63028 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-23This is a follow-up to r62675:Chris Lattner
Refactor how the preprocessor changes a token from being an tok::identifier to a keyword (e.g. tok::kw_for). Instead of doing this in HandleIdentifier, hoist this common case out into the caller, so that every keyword doesn't have to go through HandleIdentifier. This drops time in HandleIdentifier from 1.25ms to .62ms, and speeds up clang -Eonly with PTH by about 1%. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62855 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-21Add a bit to IdentifierInfo that acts as a simple predicate whichChris Lattner
tells us whether Preprocessor::HandleIdentifier needs to be called. Because this method is only rarely needed, this saves a call and a bunch of random checks. This drops the time in HandleIdentifier from 3.52ms to .98ms on cocoa.h on my machine. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62675 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-17this massive patch introduces a simple new abstraction: it makesChris Lattner
"FileID" a concept that is now enforced by the compiler's type checker instead of yet-another-random-unsigned floating around. This is an important distinction from the "FileID" currently tracked by SourceLocation. *That* FileID may refer to the start of a file or to a chunk within it. The new FileID *only* refers to the file (and its #include stack and eventually #line data), it cannot refer to a chunk. FileID is a completely opaque datatype to all clients, only SourceManager is allowed to poke and prod it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62407 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-16Change some terminology in SourceLocation: instead of referring to Chris Lattner

2009-01-15IdentifierInfo:Ted Kremenek
- IdentifierInfo can now (optionally) have its string data not be co-located with itself. This is for use with PTH. This aspect is a little gross, as getName() and getLength() now make assumptions about a possible alternate representation of IdentifierInfo. Perhaps we should make IdentifierInfo have virtual methods? IdentifierTable: - Added class "IdentifierInfoLookup" that can be used by IdentifierTable to perform "string -> IdentifierInfo" lookups using an auxilliary data structure. This is used by PTH. - Perform tests show that IdentifierTable::get() does not slow down because of the extra check for the IdentiferInfoLookup object (the regular StringMap lookup does enough work to mitigate the impact of an extra null pointer check). - The upshot is that now that some IdentifierInfo objects might be owned by the IdentiferInfoLookup object. This should be reviewed. PTH: - Modified PTHManager::GetIdentifierInfo to *not* insert entries in IdentifierTable's string map, and instead create IdentifierInfo objects on the fly when mapping from persistent IDs to IdentifierInfos. This saves a ton of work with string copies, hashing, and StringMap lookup and resizing. This change was motivated because when processing source files in the PTH cache we don't need to do any string -> IdentifierInfo lookups. - PTHManager now subclasses IdentifierInfoLookup, allowing clients of IdentifierTable to transparently use IdentifierInfo objects managed by the PTH file. PTHManager resolves "string -> IdentifierInfo" queries by doing a binary search over a sorted table of identifier strings in the PTH file (the exact algorithm we use can be changed as needed). These changes lead to the following performance changes when using PTH on Cocoa.h: - fsyntax-only: 10% performance improvement - Eonly: 30% performance improvement git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62273 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-13PTH:Ted Kremenek
- Use canonical FileID when using getSpelling() caching. This addresses some cache misses we were seeing with -fsyntax-only on Cocoa.h - Added Preprocessor::getPhysicalCharacterAt() utility method for clients to grab the first character at a specified sourcelocation. This uses the PTH spelling cache. - Modified Sema::ActOnNumericConstant() to use Preprocessor::getPhysicalCharacterAt() instead of SourceManager::getCharacterData() (to get PTH hits). These changes cause -fsyntax-only to not page in any sources from Cocoa.h. We see a speedup of 27%. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62193 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-08PTH:Ted Kremenek
- Added stub PTHLexer::getSpelling() that will be used for fetching cached spellings from the PTH file. This doesn't do anything yet. - Added a hook in Preprocessor::getSpelling() to call PTHLexer::getSpelling() when using a PTHLexer. - Updated PTHLexer to read the offsets of spelling tables in the PTH file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61911 91177308-0d34-0410-b5e6-96231b3b80d8
