Chris Lattner d7e7b8e411 first wave of fixes for @encode sema support. This is part of PR3648.
The big difference here is that (like string literal) @encode has 
array type, not pointer type.

Ted Kremenek 9b15effcd1 ccc-analyzer: Don't analyze files with '-arch ppc' or '-arch ppc64' since Clang
doesn't support Altivec intrisics nor is it likely that we're currently
generating all the right #defines, etc., for those architectures.

Douglas Gregor eddf4333fd When we're declaring an object or function with linkage, teach name
lookup to skip over names without linkage. This finishes
<rdar://problem/6127293>.

Douglas Gregor 5d68a20949 Extend the implicit declaration and checking against out-of-scope
external declarations to also support external variable
declarations. Unified the code for these two cases into two new
subroutines.

Note that we fail to diagnose cases like the one Neil pointed
out, where a visible non-external declaration hides an external
declaration by the same name. That will require some reshuffling of
name lookup.

Ted Kremenek c52f9394ce retain/release checker:
- For autorelease pool tracking, keep information about the stack of pools
  separate from their contents. Also, keep track of the number of times an
  autorelease pool will send the "release" message to an object when the pool is
  destroyed.
- Update CFRefCount::Update to return a new state instead of a reference count
  binding. This will allow us to implement more complicated semantics with
  autorelease pools.

Daniel Dunbar 5bf00893b6 Extension of GEP in constant folder was broken (apparently this code
has never been run!).
 - Sorry, don't know how to make an LLVM test case for this.

Dan Gohman 0bddac16a8 Rename ScalarEvolution's getIterationCount to getBackedgeTakenCount,
to more accurately describe what it does. Expand its doxygen comment
to describe what the backedge-taken count is and how it differs
from the actual iteration count of the loop. Adjust names and
comments in associated code accordingly.

Bill Wendling c5437ea429 Overhaul my earlier submission due to feedback. It's a large patch, but most of
them are generic changes.

- Use the "fast" flag that's already being passed into the asm printers instead
  of shoving it into the DwarfWriter.

- Instead of calling "MI->getParent()->getParent()" for every MI, set the
  machine function when calling "runOnMachineFunction" in the asm printers.

Daniel Dunbar 0b0dcd987d Some initial Obj-C zero cost EH support.
- Only handles cases with @try with no @catch blocks, and there are a
   number of problems with the implementation. Nevertheless, this is
   good enough to handled @synchronized correctly, and some other
   basic uses.

Daniel Dunbar d2fd196045 Add a very primitive clang based multifile 'delta'.
- Interface is more or less like multidelta.

 - Keep in mind it won't work very well; delta is O(N^2) frequently in
   practice. multidelta manages to work because it folds lines to keep
   N small, but this is just working on raw tokens. However, I have a
   fancy pants DAG based delta algorithm which will be the bees knees
   once I get it wired to clang.

Douglas Gregor de681d43eb In C, when we see a function declaration within a local scope, export
that declaration to global scope so that it can be found from other
scopes. This allows us to diagnose redeclaration errors for external
declarations across scopes. We also warn when name lookup finds such
an out-of-scope declaration. This is part of <rdar://problem/6127293>;
we'll also need to do the same thing for variables.

Anders Carlsson 729a8202d0 Prevent accidental copying of CodeGenFunction and CodeGenModule.
llvm-svn: 65372
2009-02-24 04:21:31 +00:00
Anders Carlsson b9c9e1d16f Pass the CodeGenModule object to GenerateBlockFunction, instead of *this (which will call the copy constructor).
Also, since we're creating a new CodeGenFunction object for each block function, we don't need to clear the BreakContinueStack.

Bill Wendling 786c5973f7 - Use the "Fast" flag instead of "OptimizeForSize" to determine whether to emit
a DBG_LABEL or not. We want to fall back to the original way of emitting debug
  info when we're in -O0/-fast mode.
- Add plumbing in to pass the "Fast" flag to places that need it.
- XFAIL DebugInfo/deaddebuglabel.ll. This is finding 11 labels instead of 8. I
  need to investigate still.

Ted Kremenek cce27f5502 Fix <rdar://problem/6611677>: Add basic transfer function support in the static
analyzer for array subscript expressions involving bases that are vectors. This
solution is probably a hack: it gets the lvalue of the vector instead of an
rvalue like all other types. This should be reviewed (big FIXME in
GRExprEngine).

SelectionDAG's copy of this code too.

Daniel Dunbar 94ceb61574 Fix two @synchronized bugs found by inspection: the expression to sychronize on should only be evaluated once, and it is evaluated outside the cleanup scope.
Also, lift SyncEnter and SyncExit up in nervous anticipation of x86-64
zero cost EH.

Ted Kremenek d6e190d899 PTH: Cache *un-cleaned* spellings for literals instead of cleaned spellings.
This allows the PTH file to stay 100% in fidelity with the source code and
defines away some weird cosmetic bugs for operations such as '-E' where
maintaining knowledge of the original literal representation is useful.

llvm-svn: 65361
2009-02-24 01:26:56 +00:00
Douglas Gregor e62c0a45dd Improve merging of function declarations. Specifically:
- When we are declaring a function in local scope, we can merge with
    a visible declaration from an outer scope if that declaration
    refers to an entity with linkage. This behavior now works in C++
    and properly ignores entities without linkage.
  - Diagnose the use of "static" on a function declaration in local
    scope.
  - Diagnose the declaration of a static function after a non-static
    declaration of the same function.
  - Propagate the storage specifier to a function declaration from a
    prior declaration (PR3425)
  - Don't name-mangle "main"
