Sebastian Redl 573feed2a8 Convert more statement actions to smart pointers.

Oscar Fuentes 963c975975 CMake: Add lib/Analysis/CaptureTracking.cpp

Duncan Sands e0aa0d677d BasicAliasAnalysis and FunctionAttrs were both 
doing very similar pointer capture analysis.
Factor out the common logic.  The new version
is from FunctionAttrs since it does a better
job than the version in BasicAliasAnalysis

Chris Lattner c671e061eb Switch MinimalAction from new/delete'ing its TypeNameInfo to 
allocating them from a recycling bump pointer allocator.  This 
reduces malloc/free traffic of parse-noop (but no other mode),
which makes sharking -parse-noop more meaningful.

Nick Lewycky e5be1cd635 Forgot this in the previous checkin: fopen now has nocapture, realloc is 
supposed to take two arguments.

Nick Lewycky 3ced0dfa69 Fix copy and pasted typos that prevented strtok_r, realloc, getenv, ungetc, 
putc, puts, perror, vscanf and vsscanf from getting annotations.

Add annotations for eight printf functions, memalign, pread and pwrite.

On Linux, llvm-gcc sometimes renames strdup, getc, putc, strtok_r, scanf and
sscanf. Match the alternate function names.

Fix a crash annotating opendir.

Don't mark fsetpos's second parameter as nocapture. It's supposed to be
captured.

Do mark fopen's path and mode strings as nocapture. Mark ferror as readonly,
but not fileno which may set errno.

Chris Lattner 144aacd19e rearrange GetIdentifierInfo so that the fast path can be partially inlined into PTHLexer::Lex. This speeds up the user time of PTH -Eonly by another 2ms (4.4%)

Chris Lattner 428613f4fc Avoid malloc thrashing on the std::vector for ConditionalStack. Because 
there is one of these per header, this almost always gets alloc/free'd for
each #ifdef.

Chris Lattner 9cdd877436 On i386 and x86-64, just do unaligned loads 
instead of assembling from bytes.  This speeds up -Eonly PTH reading 
of cocoa.h by about 2ms, which is 4.2%.

Chris Lattner 137d6492a8 switch PTHLexer to use Read32 and friends instead of lots of inlined 
copies.  I verified that this causes no performance change in PTH.

 2009-01-18 02:01:21 +00:00
Chris Lattner eb09754a9d switch PTH lexer from using "const char*"s to "const unsigned char*"s 
internally.  This is just a cleanup that reduces the need to cast to
unsigned char before assembling a larger integer.

Chris Lattner 71dc14b9f0 Rename SourceLocation::getFileID to getChunkID, because it returns 
the chunk ID not the file ID.  This exposes problems in 
TextDiagnosticPrinter where it should have been using the canonical
file ID but wasn't.  Fix these along the way.

llvm-svn: 62427
 2009-01-17 08:45:21 +00:00
Chris Lattner 5509d533f6 simplify some lookups.

 2009-01-17 08:30:10 +00:00
Chris Lattner 757169b60f Change the Lexer ctor used to lex _Pragma directives into a static factory 
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.

 2009-01-17 08:05:14 +00:00
Chris Lattner c809089b26 Change the Lexer ctor used in the non _Pragma case to take a FileID instead 
of a SourceLocation.  This should speed it up and definitely simplifies it.

Chris Lattner 8ddb5cf0cf in Preprocessor::AdvanceToTokenCharacter, don't actually bother 
creating a whole lexer when we just want one static method.
