2009-03-19Add PTHManager::getOriginalSourceFile(), a method that returns the name of theTed Kremenek
original source file (if any) that was used to generate the PTH cache. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67343 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-14Revert the switch to the tablegen diags. It fails for seperate objdir builds ↵Sebastian Redl

2009-03-08simplify some logic by making ScratchBuffer handle the application of trailingChris Lattner
\0's to created tokens instead of making all clients do it. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66373 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-04make the token lexer allocate its temporary token buffers forChris Lattner
preexpanded macro arguments from the preprocessor's bump pointer. This reduces # mallocs from 12444 to 11792. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66025 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-25Implement parsing of nested-name-specifiers that involve template-ids, e.g.,Douglas Gregor
std::vector<int>::allocator_type When we parse a template-id that names a type, it will become either a template-id annotation (which is a parsed representation of a template-id that has not yet been through semantic analysis) or a typename annotation (where semantic analysis has resolved the template-id to an actual type), depending on the context. We only produce a type in contexts where we know that we only need type information, e.g., in a type specifier. Otherwise, we create a template-id annotation that can later be "upgraded" by transforming it into a typename annotation when the parser needs a type. This occurs, for example, when we've parsed "std::vector<int>" above and then see the '::' after it. However, it means that when writing something like this: template<> class Outer::Inner<int> { ... }; We have two tokens to represent Outer::Inner<int>: one token for the nested name specifier Outer::, and one template-id annotation token for Inner<int>, which will be passed to semantic analysis to define the class template specialization. Most of the churn in the template tests in this patch come from an improvement in our error recovery from ill-formed template-ids. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65467 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-20switch the macroinfo argument lists from being allocated off the heapChris Lattner
to being allocated from the same bumpptr that the MacroInfo objects themselves are. This speeds up -Eonly cocoa.h pth by ~4%, fsyntax-only is barely measurable. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65195 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65179 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-18Next step toward making string diagnostics correct: handleChris Lattner
escapes in the string for subtoken positioning. This gives us working examples like: t.m:5:16: warning: field width should have type 'int', but argument has type 'unsigned int' printf("\n\n%*d", (unsigned) 1, 1); ^ ~~~~~~~~~~~~ where before the caret pointed two spaces to the left. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64940 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
2009-02-13Add some boilerplate to the PTH file to prepare for the caching of stats for ↵Ted Kremenek
directories (and negative stats too). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64477 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-13factor token concatenation avoidance logic out of Chris Lattner
PrintPreprocessedOutput into its own file. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64418 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
2009-02-11PTH: Have meta data be at the beginning of the PTH file, not the end.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64338 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-11PTH: Replace string identifier to persistent ID lookup with a hashtable. This isTed Kremenek
actually *slightly* slower than the binary search. Since this is algorithmically better, further performance tuning should be able to make this faster. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64326 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-11PTH: Don't emit the PTH offset of the IdentifierInfo string data as that data isTed Kremenek
referenced by other tables. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64304 91177308-0d34-0410-b5e6-96231b3b80d8

diffing the output of: clang -dM -o - -E -x c foo.c | sort git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63926 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63925 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-29next round of diagnostics cleanups, moving some Chris Lattner
diags around, eliminating #defines, etc. Patch by Anders Johnsen! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63318 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-29Fix -Wimplicit-function-declaration, which required some refactoring andChris Lattner
changes in various diagnostics code. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63282 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-29move library-specific diagnostic headers into library private dirs. ReduceChris Lattner
redundant #includes. Patch by Anders Johnsen! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63271 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-28Enhance PTHManager::Create() to take an optional Diagnostic* argument that ↵Ted Kremenek
can be used to report issues such as a missing PTH file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63231 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
2009-01-26rename getSpelledCharacterAt to getSpellingOfSingleCharacterNumericConstant,Chris Lattner
optimize it to use the LiteralData when possible. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63060 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-26Add version number to PTH files.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63052 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
2009-01-26add parsing and constraint enforcement for GNU line marker directives.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63003 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-26parse and enforce required constraints on #line directives. Right nowChris Lattner
we just discard them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62999 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-26Check in the long promised SourceLocation rewrite. This lays theChris Lattner
ground work for implementing #line, and fixes the "out of macro ID's" problem. There is nothing particularly tricky about the code, other than the very performance sensitive SourceManager::getFileID() method. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62978 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-23Preprocessor doesn't require and IdentifierInfoLookup object.Chris Lattner
Patch by Axel Naumann! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62854 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-19Make SourceLocation::getFileLoc private to reduce the API exposure of Chris Lattner
SourceLocation. This requires making some cleanups to token pasting and _Pragma expansion. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62490 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-18rearrange GetIdentifierInfo so that the fast path can be partially inlined ↵Chris Lattner
into PTHLexer::Lex. This speeds up the user time of PTH -Eonly by another 2ms (4.4%) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62454 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-18Avoid malloc thrashing on the std::vector for ConditionalStack. BecauseChris Lattner
there is one of these per header, this almost always gets alloc/free'd for each #ifdef. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62451 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-18switch PTH lexer from using "const char*"s to "const unsigned char*"s Chris Lattner
internally. This is just a cleanup that reduces the need to cast to unsigned char before assembling a larger integer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62442 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-17Change the Lexer ctor used to lex _Pragma directives into a static factoryChris Lattner
method. This lets us clean up the interface and make it more obvious that this method is *really really* _Pragma specific. Note that _Pragma handling uglifies the Lexer in the critical path. It would be very interesting to consider making _Pragma remapping be a new special lexer class of its own. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62425 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62424 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-17Change the Lexer ctor used in the non _Pragma case to take a FileID insteadChris Lattner
of a SourceLocation. This should speed it up and definitely simplifies it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62422 91177308-0d34-0410-b5e6-96231b3b80d8
