Owen Anderson 29ec3e0e50 Use LLVMContext to generate metadata constants.

Douglas Gregor c6d5edd2ed Add support for retrieving the Doxygen comment associated with a given 
declaration in the AST. 

The new ASTContext::getCommentForDecl function searches for a comment
that is attached to the given declaration, and returns that comment, 
which may be composed of several comment blocks.

Comments are always available in an AST. However, to avoid harming
performance, we don't actually parse the comments. Rather, we keep the
source ranges of all of the comments within a large, sorted vector,
then lazily extract comments via a binary search in that vector only
when needed (which never occurs in a "normal" compile).

Comments are written to a precompiled header/AST file as a blob of
source ranges. That blob is only lazily loaded when one requests a
comment for a declaration (this never occurs in a "normal" compile). 

The indexer testbed now supports comment extraction. When the
-point-at location points to a declaration with a Doxygen-style
comment, the indexer testbed prints the associated comment
block(s). See test/Index/comments.c for an example.

Some notes:
  - We don't actually attempt to parse the comment blocks themselves,
  beyond identifying them as Doxygen comment blocks to associate them
  with a declaration.
  - We won't find comment blocks that aren't adjacent to the
  declaration, because we start our search based on the location of
  the declaration.
  - We don't go through the necessary hops to find, for example,
  whether some redeclaration of a declaration has comments when our
  current declaration does not. Similarly, we don't attempt to
  associate a \param Foo marker in a function body comment with the
  parameter named Foo (although that is certainly possible).
  - Verification of my "no performance impact" claims is still "to be
  done".

Chris Lattner ccfb5105eb simplify some logic by using isWeakForLinker(). Thanks to Anton for 
pointing this out.

Chris Lattner edb8407f0c do not try to analyze bitcasts from i64 to <2 x i32> in ComputedMaskedBits. While 
we could do this, doing so requires adjusting the demanded mask and the code isn't 
doing that yet.  This fixes PR4495

llvm-svn: 74699
 2009-07-02 16:04:08 +00:00
Chris Lattner f3f6aaa2c3 fix inverted logic pointed out by John McCall, noticed by inspection. 
This was considering vector intrinsics to have cost 2, but non-vector
intrinsics to have cost 1, which is backward.

Owen Anderson 31d44e4904 Restore other bits of the C API that I tore up. All pre-existing APIs default to using the 
default global context, while new *InContext() APIs have been added that take a LLVMContextRef parameter.

Apologies to anyone affected by this breakage.

Evan Cheng 2c450d35ae Change the meaning of predicate hasThumb2 to mean thumb2 ISA is available, not that it's in thumb mode and thumb2 is available. Added isThumb2 predicate to replace the old predicate.

Chris Lattner 87bb642676 @GOTPCREL is also rip-relative. Fix fast-isel to do the right thing. 
This fixes an llvm-gcc bootstrap problem I introduced.

Daniel Dunbar 9bff6531fd llvm-mc/x86: Fix bug in disambiguation of displacement operand, introduced by me 
(I think).
 - We weren't properly parsing the leading parenthesized expression in something
   like 'push (4)(%eax)'.
 
 - Added ParseParenRelocatableExpression to support this. I suspect we should
   just use lookahead, though.

 - Test case to follow.

Chris Lattner 4ec83ea628 clarify: stub emission depends on the version of the linker you use, it has nothing 
to do with the target.  Also, the stub elimination optimization *requires* making the
stub explicit.

Ted Kremenek a8a295f2d9 Temporarily disable RegionStore for stack-addr-ps.c, as a new test case reveals 
a case where RegionStore doesn't create symbolic values for the fields of
structs that are passed-by-value.

Dan Gohman cf092389a9 Request LCSSA after LoopSimplify. This fixes a problem in which the 
PassManager was scheduling LCSSA before LoopSimplify, which does not
preserve LCSSA.

llvm-svn: 74661
 2009-07-01 23:21:38 +00:00
Ted Kremenek 55e07efeed Add a FIXME to RegionStore, do some minor code cleanup, and get RegionStore to 
pass misc-ps.m. Currently RegionStore/BasicStore don't do any special reasoning
about clang-style vectors, so we should return UnknownVal (in all cases) when
accessing their values via an array.
