Chris Lattner 68e486804f Rename IdentifierInfo::isName to ::isStr. Use a nifty trick 
from Sebastian to enforce that a literal string is passed in,
and use this to avoid having to call strlen on it.

Dan Gohman 186f65d275 Factor out the SethiUllman numbering logic from the list-burr and 
list-tdrr schedulers into a common base class.

Dan Gohman fd08af4ee7 Remove the "fast" form of the list-burr scheduler, and use the 
dedicated "fast" scheduler in -fast mode instead, which is
faster. This speeds up llc -fast by a few percent on some
testcases -- the speedup only happens for code not handled by
fast-isel.

Oscar Fuentes 4d69fd4f1c CMake: when building shared libraries, use -fPIC for compiling 
partially linked objects.

Dan Gohman 3f656dfa03 Facter AddPseudoTwoAddrDeps and associated infrasructure out of 
the list-burr scheduler so that it can be used by the list-tdrr
scheduler too.

Evan Cheng c22215a090 - Register scavenger should use MachineRegisterInfo and internal map to find the first use of a register after a given machine instruction. 
- When scavenging a register, in addition to the spill, insert a restore before the first use.
- Abort if client is looking to scavenge a register even when a previously scavenged register is still live.

Ted Kremenek b33ce32bda Preprocessor::getCurrentFileLexer() now returns a PreprocessorLexer* instead of 
a Lexer*. This means it will either return the current (normal) file Lexer or a
PTHLexer.

Ted Kremenek 300590b584 Just use the SourceLocation of SysHeaderTok when doing a callback to emit #line 
information. A diff of the -E output for Cocoa.h shows that there is no change
in output.

Dan Gohman 4ce15e12b9 Factor out the code for verifying the work of the scheduler, 
extend it a bit, and make use of it in all schedulers, to
ensure consistent checking.

Dan Gohman 4c3034f711 Simplify this code a little. In the fast scheduler, CreateNewSUnit 
and CreateClone don't add any extra value.

Dan Gohman 60cb69e665 Experimental post-pass scheduling support. Post-pass scheduling 
is currently off by default, and can be enabled with
-disable-post-RA-scheduler=false.

This doesn't have a significant impact on most code yet because it doesn't
yet do anything to address anti-dependencies and it doesn't attempt to
disambiguate memory references. Also, several popular targets
don't have pipeline descriptions yet.

The majority of the changes here are splitting the SelectionDAG-specific
code out of ScheduleDAG, so that ScheduleDAG can be moved to
libLLVMCodeGen.a. The interface between ScheduleDAG-using code and
the rest of the scheduling code is somewhat rough and will evolve.

Douglas Gregor ab7897ac44 Implement the rest of C++ [over.call.object], which permits the object 
being called to be converted to a reference-to-function,
pointer-to-function, or reference-to-pointer-to-function. This is done
through "surrogate" candidate functions that model the conversions
from the object to the function (reference/pointer) and the
conversions in the arguments.

 2008-11-19 22:55:55 +00:00
Ted Kremenek 2861cf42fe Use PreprocessorLexer::getFileID() instead of Lexer::getFileLoc(). This is an intermediate step to having getCurrentLexer() return a PreprocessorLexer* instead of a Lexer*. 
llvm-svn: 59672
 2008-11-19 22:55:25 +00:00
Ted Kremenek a2c3c8d71c Move more cases of using 'CurLexer' to 'CurPPLexer'. 
Use PTHLexer::isNextPPTokenLParen() when using the PTHLexer.

llvm-svn: 59671

Dan Gohman f4d95fdce9 Move the code for printing a graph node label for an SUnit into 
a virtual method of SelectionDAG.

Ted Kremenek 45245217bc - Move static function IsNonPragmaNonMacroLexer into Preprocessor.h. 
- Add variants of IsNonPragmaNonMacroLexer to accept an IncludeMacroStack entry
  (simplifies some uses).
- Use IsNonPragmaNonMacroLexer in Preprocessor::LookupFile.
- Add 'FileID' to PreprocessorLexer, and have Preprocessor query this fileid
  when looking up the FileEntry for a file

Performance testing of -Eonly on Cocoa.h shows no performance regression because
of this patch.

Steve Naroff dbfc693f47 Fix <rdar://problem/6291588> assertion failure: SourceManager.h line 489.

Douglas Gregor 91cea0ad1e Support for calling overloaded function call operators (operator()) 
with function call syntax, e.g.,

  Functor f;
  f(x, y);

This is the easy part of handling calls to objects of class type 
(C++ [over.call.object]). The hard part (coping with conversions from
f to function pointer or reference types) will come later. Nobody uses
that stuff anyway, right? :)

Devang Patel 7ed6c5317c If there are two consecutive llvm.dbg.stoppoint calls then 
it is likely that the optimizer deleted code in between these
two intrinsics. Keep only the last llvm.dbg.stoppoint in this case.
