2009-02-04lower the interface to getLineNumber like we did forChris Lattner
getColumnNumber. This fixes a FIXME in SourceManager::getPresumedLoc because we now just decompose the sloc once. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63701 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-30avoid emitting a bogus line marker for the top level #includeChris Lattner
location. We now -E a file containing "foo" into: # 1 "t.c" # 1 "t.c" 1 # 1 "<predefines>" 1 # 1 "t.c" 2 foo instead of: # 1 "t.c" # 1 "t.c" 1 # 0 "t.c" # 1 "<predefines>" 1 # 1 "t.c" 2 foo git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63405 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

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63029 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

2009-01-16Change some terminology in SourceLocation: instead of referring to Chris Lattner
the "physical" location of tokens, refer to the "spelling" location. This is more concrete and useful, tokens aren't really physical objects! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62309 91177308-0d34-0410-b5e6-96231b3b80d8

2008-09-05Workaround gcc bug causing crash on our preprocessed outputs.Daniel Dunbar
- gcc is not happy if we start a preprocessed file with #line 1 "XXX" 1 - Workaround by making sure file starts with a simple #line change. Also, factored WriteLineInfo out. Also, fixed bug where FileType was not being correctly updated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55825 91177308-0d34-0410-b5e6-96231b3b80d8

2007-12-29Don't attribute in file headers anymore. See llvmdev for theChris Lattner
discussion of this change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45410 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

2007-12-09The flags on tokens indicate whether they are the start of a *physical* line, Chris Lattner
not the start of a logical line. Be careful about this distinction, which affects when newlines are printed and when paste-avoidance happens, etc. This fixes PR1848, thanks to Neil for noticing this! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44743 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-09Fix a pretty big but subtle bug counting the number of newlines to emit.Chris Lattner
This would cause us to emit different code (in -E mode) for these two files: --- #define t(x) x t(a 3) --- #define t(x) x t(a 3) --- In one case, -E would print "a\n3", in the other it printed "a3". Now it prints "a3" for both. This is part of PR1848. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44742 91177308-0d34-0410-b5e6-96231b3b80d8

2007-10-09Make a significant change to invert the control flow handlingChris Lattner
predefined macros. Previously, these were handled by the driver, now they are handled by the preprocessor. Some fallout of this: 1. Instead of preprocessing two buffers (the predefines, then the main source file) we now start preprocessing the main source file and inject the predefines as a "psuedo #include" from the main source file. 2. #1 allows us to nuke the Lexer::IsMainFile flag and simplify Preprocessor::isInPrimaryFile. 3. The driver doesn't have to know about standard #defines, the preprocessor knows, which is nice for people wanting to define their own drivers. 4. This allows us to put normal tokens in the predefine buffer, for example a definition for __builtin_va_list that is target-specific, and a typedef for id in objc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42818 91177308-0d34-0410-b5e6-96231b3b80d8
