2009-03-09fix PR3764 - A redefinition of a pre-processor macro failsChris Lattner
Redefinition checking should ignore the leading whitespace and start of line flags on the first token of an expansion. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66442 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-08add \n characters to the scratch buffer *before* returned tokens. Chris Lattner
This prevents caret diagnostics from the scratch buffer from including other tokens in the scratch buffer that occurred beforei them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66375 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

2009-02-20switch 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

t.c:1:10: error: missing terminating '>' character #include <stdio.h ^ instead of: t.c:1:10: error: missing terminating " character #include <stdio.h ^ git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65052 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

2009-02-18Fix 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

2009-02-15add a new SourceManager::getInstantiationRange helper method.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64606 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-15fix PR3579: __LINE__ expands to the presumed location of the Chris Lattner
*end* of a macro instantiation, not the start of it. This is really all about bug-for-bug compatibility with GCC, but not doing this breaks the FreeBSD kernel. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64604 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
2009-02-13PTH: Cache directory and negative 'stat' calls. This gives us a 1% ↵Ted Kremenek
performance improvement on Cocoa.h (fsyntax-only+PTH). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64490 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

2009-02-11PTH: 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
2009-02-10PTH: Replace ad hoc 'file name' -> 'PTH data' lookup table in the PTH file ↵Ted Kremenek
with an on-disk chained hash table. This data structure is implemented using templates, and will be used to replace similar data structures. This change leads to no visibile performance impact on Cocoa.h, but now we only pay a price for the table on order with the number of files accessed and not the number in the PTH file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64245 91177308-0d34-0410-b5e6-96231b3b80d8
