Daniel Dunbar eb27e7d999 c-index-test: Simplify file scanning code. 
llvm-svn: 96159
 2010-02-14 08:32:32 +00:00
Daniel Dunbar 98c07e0e23 c-index-test: Unify syntax for printing extents. Yes, there were 4. 
llvm-svn: 96158
 2010-02-14 08:32:24 +00:00
Daniel Dunbar 2049933196 CIndex: Simplify (remove provably dead code).

 2010-02-14 08:32:11 +00:00
Daniel Dunbar 2f4ba179f5 CIndex: Inline CompareRegionOfInterest(CXSourceRange) into sole caller. 
llvm-svn: 96156
 2010-02-14 08:32:05 +00:00
Daniel Dunbar 80daf53600 Rename translateSourceRange(CXSourceRange) translateCXSourceRange, instead of 
having overloaded functions with inverse semantics.

Zhongxing Xu be36ecbb60 Fix pr6293. If ptr is NULL, no operation is preformed.

Johnny Chen c95a814ec3 Try to factorize the specification of saturating add/subtract operations a bit, 
as suggested by Bob Wilson.

Dan Gohman 2d0f96d49a Actually, this code doesn't have to be quite so conservative in 
the no-TLI case. But it should still default to declining the
transformation.

Dan Gohman 6b7517342e In rememberInstruction, if the value being remembered is the 
current insertion point, advance the current insertion point.
This avoids a use-before-def situation in a testcase extracted
from clang which is difficult to reduce to a reasonable-sized
regression test.

Dan Gohman f446713fd0 Simplify this code; no need for a custom subclass if it doesn't need 
to override anything from the parent class.

llvm-svn: 96150
 2010-02-14 02:48:58 +00:00
Dan Gohman 6fafffb635 Remove a 'protected' keyword, now that SCEVExpander is no longer 
intended to be subclassed.

Dan Gohman cb76a806f0 Don't attempt aggressive post-inc uses if TargetLowering is not available, 
because profitability can't be sufficiently approximated.

Ted Kremenek 184b3383bf Add new static analyzer for checking LLVM coding conventions: -analyzer-check-llvm-conventions 
Currently these checks are intended to be largely syntactical, but may get more
sophisticated over time.

As an initial foray into this brave new world, emit a static analyzer warning
when binding a temporary 'std::string' to an 'llvm::StringRef' where the
lifetime of the 'std::string' does not outlive the 'llvm::StringRef'.

llvm-svn: 96147
 2010-02-14 02:45:18 +00:00
Ted Kremenek eff72bb134 Two changes to AnalysisConsumer::HandleTopLevelSingleDecl(): 
(1) Since CXXMethodDecl subclasses FunctionDecl (and CXXDestructorDecl 
and CXXConversion subclass CXXMethodDecl), refactor switch statement 
to handle them all in one spot.

(2) Use 'DeclarationName::getAsString()' to handle all functions that
don't have simple identifiers (fixing a null dereference when scanning
for specific functions).

Daniel Dunbar c4b4d3953c CIndex: Kill off CXSourceLocationPtr, and AtEnd arguments. 
llvm-svn: 96145
 2010-02-14 01:47:36 +00:00
Daniel Dunbar 474b207716 CIndex: Stop hiding magic end bit in CXSourceRange locations where clients can't 
see it. Instead, translate the locations up-front when we create a
CXSourceRange.
 - This is part of a move to make CXSourceRange a pure half-open range, which is
   a more natural API for clients to deal with. More cleanups to follow.

Daniel Dunbar 3e255dae88 2.7: Note that DataTypes.h moved. 
llvm-svn: 96143
 2010-02-14 01:47:19 +00:00
John McCall 38200b081a Improve the diagnostic given when referring to a tag type without a tag (in C) 
or that's been hidden by a non-type (in C++).

The ideal C++ diagnostic here would note the hiding declaration, but this
is a good start.

Anders Carlsson 073a0c88cc Build fix.

 2010-02-14 00:22:59 +00:00
Anders Carlsson 258a1e35e8 Improve support for non-virtual 'this' pointer adjustments. With this, it should be possible to use the new vtable layout code for all class hierarchies that do not involve virtual bases. 
llvm-svn: 96137
 2010-02-14 00:16:19 +00:00
Anders Carlsson d3adb0ced9 Add basic support for simple non-virtual 'this' pointer adjustments.

John McCall 0daaf13b97 Make LSR not crash if invoked without target lowering info, e.g. if invoked 
from opt.

 2010-02-13 23:40:16 +00:00
Eric Christopher 843a4cc43c Fix a problem where we had bitcasted operands that gave us 
odd offsets since the bitcasted pointer size and the offset pointer
size are going to be different types for the GEP vs base object.

llvm-svn: 96134
 2010-02-13 23:38:01 +00:00
Anders Carlsson cce9ee8970 Add support for very simple non-virtual this adjustments in the FinalOverriders class.

Mikhail Glushenkov 32fa169648 Forward parameter options as '-option=parameter'. 
Some tools do not like the '-option parameter' form. Should this be
configurable?

llvm-svn: 96130
 2010-02-13 22:37:28 +00:00
Mikhail Glushenkov bbbf4977c7 Support some more Darwin-only options. 
We really need a conditional compilation mechanism...

Mikhail Glushenkov b0afb6cbe4 Support -mfix-and-continue properly.

 2010-02-13 22:37:00 +00:00
Mikhail Glushenkov 67f061d85c Revert r94752, turns out we don't need to touch these options.

Daniel Dunbar ae4b77d99d cindex/Python: Fix cindex-{dump,includes} examples to just pass all args 
directly to Index, instead of requiring the input file to be first. This makes
the examples behave more like 'clang'.

For example,
  ddunbar@giles:tmp$ echo '#include <string>' | python ~/llvm/tools/clang/bindings/python/examples/cindex/cindex-includes.py -- -x c++ - | wc -l
     114
  ddunbar@giles:tmp$ echo '#include <stdio.h>' | python ~/llvm/tools/clang/bindings/python/examples/cindex/cindex-includes.py -- -x c - | wc -l

Charles Davis 4ea31ab369 Emit the 'alignstack' LLVM function attribute when we encounter a function 
marked 'force_align_arg_pointer'. Almost there; now all I need to do is finish
up the backend.
