Abramo Bagnara d73405829b Added AccessSpecDecl node. 
llvm-svn: 105525
 2010-06-05 05:09:32 +00:00
Alexis Hunt ed05325dbe Convert DeclNodes to use TableGen. 
The macros required for DeclNodes use have changed to match the use of
StmtNodes. The FooFirst enumerator constants have been named firstFoo
to match usage elsewhere.

Fariborz Jahanian 5f81b9f3f6 Patch to fix a irgen crash accessing an initialized local static 
variable in a local function. Fixes pr7101.

John McCall 7cb0220e53 If a function definition has any sort of weak linkage, its static local 
variables should have that linkage.  Otherwise, its static local
variables should have internal linkage.  To avoid computing this excessively,
set a function's linkage before we emit code for it.

Previously we were assigning weak linkage to the static variables of
static inline functions in C++, with predictably terrible results.  This
fixes that and also gives better linkage than 'weak' when merging is required.

Douglas Gregor 9154b5dffe Ensure that destructors are called for NRVO'd objects when the 
function does not return. Thanks to Eli for pointing out this corner
case.

 2010-05-17 15:52:46 +00:00
Douglas Gregor 170125648c When applying the named return value optimization, we still need to 
destroy the variable along the exceptional edge; it's only during
normal execution that we avoid destroying this variable.

llvm-svn: 103872
 2010-05-15 16:39:56 +00:00
Douglas Gregor 290c93ec0d Implement a simple form of the C++ named return value optimization for 
return statements. We perform NRVO only when all of the return
statements in the function return the same variable. Fixes some link
failures in Boost.Interprocess (which is relying on NRVO), and
probably improves performance for some C++ applications.

John McCall 4a39ab8078 Emit the globals, metadata, etc. associated with static variables even when 
they're unreachable.  This matters because (if they're POD, or if this is C)
the scope containing the variable might be reachable even if the variable
isn't.  Fixes PR7044.

John McCall 7ec5043c2c Change CodeGenModule to rely on the Module's symbol table instead of 
shadowing it in the GlobalDeclMap.  Eliminates the string-uniquing
requirement for mangled names, which should help C++ codegen times a little.
Forces us to do string lookups instead of pointer lookups, which might hurt
codegen times a little across the board.  We'll see how it plays out.

Removing the string-uniquing requirement implicitly fixes any bugs like
PR6635 which arose from the fact that we had multiple uniquing tables for
different kinds of identifiers.

 2010-03-19 23:29:14 +00:00
Fariborz Jahanian c6140734c5 Fix a rare corner case bug which exposed a serious block API generation 
when initialized variable is a byref block variable and is referenced recursively
in the initializer (you guessed it, it is block implementation of
fibonacci number). Fix, on the other hand is trvial, by generating the
API for byref variable before API for its initializer. We will have this
test added to our internal test suite as a clang-style test is not possible
due to very convoluted IR sequence. Fixes radar 7745514.

Daniel Dunbar a7566f163a IRgen: Add CreateMemTemp, for creating an temporary memory object for a particular type, and flood fill. - CreateMemTemp sets the alignment on the alloca correctly, which fixes a great many places in IRgen where we were doing the wrong thing. 
- This fixes many many more places than the test case, but my feeling is we need to audit alignment systematically so I'm not inclined to try hard to test the individual fixes in this patch. If this bothers you, patches welcome!

Mike Stump 2c002929b2 Fixup debug information for the location information for __block 
variables.  For this to work, the backend needs to handle more complex
forms for locations.

A typical utterance would be:

        %forwarding = getelementptr %0* %use_by_ref, i32 0, i32 1               ; <i8**> [#uses=1]
        %0 = load i8** %forwarding              ; <i8*> [#uses=1]
        %1 = bitcast i8* %0 to %0*              ; <%0*> [#uses=1]
        %x = getelementptr %0* %1, i32 0, i32 4         ; <i32*> [#uses=1]
        %2 = bitcast i32* %x to { }*            ; <{ }*> [#uses=1]
        call void @llvm.dbg.declare({ }* %2, { }* bitcast (%llvm.dbg.variable.type* @llvm.dbg.variable to { }*))

Presently when selection finds something it doesn't understand, it
just avoids generating any information, which is safe, just
incomplete.  Radar 6867696

I'm skeptical that __private_extern__ should actually be a storage
class value. I think that __private_extern__ basically amounts to
  extern A __attribute__((visibility("hidden")))
and would be better off handled (a) as that, or (b) with an extra bit
in the VarDecl.

Daniel Dunbar 38ad1e6138 Change EmitConstantExpr to allow failure. 
IRgen no longer relies on isConstantInitializer, instead we just try
to emit the constant. If that fails then in C we emit an error
unsupported (this occurs when Sema accepted something that it doesn't
know how to fold, and IRgen doesn't know how to emit) and in C++ we
emit a guarded initializer.

This ends up handling a few more cases, because IRgen was actually
able to emit some of the constants Sema accepts but can't Evaluate().
For example, PR3398.

Douglas Gregor 5fec5b0495 Add basic support for C++ name mangling according to the Itanium C++ 
ABI to the CodeGen library. Since C++ code-generation is so
incomplete, we can't exercise much of this mangling code. However, a
few smoke tests show that it's doing the same thing as GCC. When C++
codegen matures, we'll extend the ABI tester to verify name-mangling
as well, and complete the implementation here.

At this point, the major client of name mangling is in the uses of the
new "overloadable" attribute in C, which allows overloading. Any
"overloadable" function in C (or in an extern "C" block in C++) will
be mangled the same way that the corresponding C++ function would be
mangled.

Chris Lattner 7a51313d8a Make a major restructuring of the clang tree: introduce a top-level 
lib dir and move all the libraries into it.  This follows the main
llvm tree, and allows the libraries to be built in parallel.  The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in.  This speeds
up parallel builds, particularly incremental ones.
