Chris Lattner 3637652ab3 random code cleanups. 
llvm-svn: 67437
 2009-03-21 07:12:05 +00:00
Chris Lattner 6098e62d56 remove obviously dead code: you can't bitcast a pointer to "Ty" (a function type). 
llvm-svn: 67436
 2009-03-21 06:58:21 +00:00
Chris Lattner 9e8120e067 avoid making constant folding logic eliminate obviously dead bitcasts, speeding up PR3810 
by ~2%.

llvm-svn: 67434
 2009-03-21 06:53:34 +00:00
Chris Lattner 725a26b818 Add a fast path to CodeGenModule::getMangledName for almost all C functions, 
speeding up the testcase in PR3810 by 60%.

Daniel Dunbar 4e004ed124 IRgen support for alias of global variable. 
- PR3818.

Fariborz Jahanian 3654e65adf objc: Implemented variables declared in class interface 
whose sema decl is at the translation unit.

Duncan Sands 1918413137 Adjust for linkage name change. 
llvm-svn: 66691

Duncan Sands bdf086f7c0 Correct for change of this name in LLVM.

Daniel Dunbar 99d2835099 Backout r66408, we don't want handling of globals to rely on the 
module symbol table. The root problem inspiring this was fixed in
r66316 (and again in r66506).

Mike Stump e3193ff452 Be sure to never create two functions with the same name, instead arrange to 
reuse the prior one.

Eli Friedman 4663a3368d Make constant emission for @encode use the common string emission code. 
This is a bit cleaner, and also "fixes" bad code that compares the 
addresses of the string constants.

Mike Stump a6ca334389 Fixup our uses of various linkages to match how llvm now works. I think they are all 
correct, but an extra set of ObjC eyes would be good.

 2009-03-07 16:33:28 +00:00
Daniel Dunbar 7aecee998c (LLVM svn up) Generalize RuntimeFunctions to RuntimeGlobals and add 
CodeGenModule::CreateRuntimeVariable.

 - No real functionality change; although we now assert on silly
   things like:
--
int objc_exception_throw;
void f0() { @throw(@"A"); }
--
   instead of accepting it.

Daniel Dunbar 8e79b8491f IRgen support for weak_import. 
- <rdar://problem/6652110> clang should support weak_import

llvm-svn: 66270
 2009-03-06 16:20:49 +00:00
Daniel Dunbar f804897ee9 Don't mangle names of local variables. 
- For one thing, this adds unneeded overhead; for another, this
   routine can be used to emit unnamed decls which we shouldn't try to
   mangle.

llvm-svn: 66212
 2009-03-05 22:59:19 +00:00
Eli Friedman cecc21d2f6 Make IRGen compatible with declaring a function with incomplete 
return/argument types.  (The generated IR isn't ideal, but we can't 
really do better in general.)

Mike Stump 6c39666a77 Move more of the blocks code up and out. 
llvm-svn: 66046
 2009-03-04 18:47:42 +00:00
Mike Stump 95435674f9 Move more of blocks codegen out of CodeGenModule and into the 
BlockModule.  No functionality change.  This should help people that
don't want to know anything about blocks not be confused by the
overloaded use of the term block or nor want to see all the blocks
goop.

Daniel Dunbar 5b9e9682f1 Support "asm" renaming of external symbols. 
- PR3698.

Daniel Dunbar 0f3403cb5a Don't set nounwind on functions when in using the new Obj-C ABI.

Chris Lattner a01c21f616 simplify some code.

Anders Carlsson 655129990a Initialize NSConcreteStackBlock

Mike Stump 537abb0dec Fix PR3612. We ensure that we add builtins to the GlobalDeclMap and 
we ensure that things added to the module can be found even when they
are not in GlobalDeclMap.  The later is for increased flexibility,
should someone want to do something tricky like extern "Ada" in the
same module.

llvm-svn: 65657

Eli Friedman 97e070ed68 Minor cleanup: use getDeclAlignInBytes helper. 
llvm-svn: 65611
 2009-02-27 04:11:37 +00:00
Chris Lattner d42c29f9a2 fix some sema problems with wide strings and hook up basic codegen for them.
