Ted Kremenek 3b33e2544a Fixed bug in ObjCIVarExpr: the child iterator now iterates over the Base expression. 
llvm-svn: 50585
 2008-05-02 18:40:22 +00:00
Ted Kremenek 789942cfda When running the reference count checker twice (GC and non-GC mode), only emit 
basic warnings (dead stores, null dereferences) on the first pass.

Ted Kremenek a06e7120bb Bug fix in StmtPrinter to handle pretty-printing ObjCMessageExprs involving variadic methods (also did some cosmetic cleanups in the printing output).

Evan Cheng fa8f9f937a Undo r50574. We are already ensuring the folded load address is 16-byte aligned.

 2008-05-02 07:53:32 +00:00
Evan Cheng 50f82f2c8e Not safe folding a load + FsXORPSrr into FsXORPSrm. It's loading a FR64 value but the load folding variant expects a 16-byte aligned address.

llvm-svn: 50548
 2008-05-01 22:50:14 +00:00
Dale Johannesen 78ffe6e939 Don't try to create PHIs of struct types. Fallout 
from x86-64 calling convention work.

llvm-svn: 50545
 2008-05-01 22:27:44 +00:00
Steve Naroff f8ecff2a94 Replace Sema::CheckInitializerListTypes() with a helper class (InitListChecker) that synthesizes implicit InitListExpr's when appropriate (see InitListExpr comments in Expr.h for more details). I also moved the code to SemaInit.cpp, to help reduce clutter in SemaDecl.cpp. 
NOTE: This work is incomplete and still fails many tests (as a result, it isn't enabled yet). Nevertheless, I wanted to check it in so I can work on it from home.

llvm-svn: 50540
 2008-05-01 21:26:22 +00:00
Argyrios Kyrtzidis 694dda1e4e Implicitly defined functions were getting the DeclContext of the function where they appeared, causing the bug: http://llvm.org/bugs/show_bug.cgi?id=2266. 
Fix it by making implicitly defined functions get the DeclContext of translation unit.

 2008-05-01 21:04:16 +00:00
Dan Gohman 4be6ae4e6c Fix an overaggressive SimplifyDemandedBits optimization on urem. This 
fixes the 254.gap regression on x86 and the 403.gcc regression on x86-64.

Ted Kremenek 7f824734e0 Added temporary fix for Obj-C exception handling in the static analyzer: treat these as panic functions. 
llvm-svn: 50535
 2008-05-01 18:33:28 +00:00
Ted Kremenek 88f8ebdf76 Added default ctor to Selector.

operations with ADTs that need to default constructor selectors.

Ted Kremenek b8861a6ccf Use pointer swizziling to unify in ObjCMessageExpr the receiver and classname "fields". This saves us a pointer.

 2008-05-01 17:08:00 +00:00
Ted Kremenek ed36e4b9a4 Added ziperr as a panic function. Eventually inter-procedural analysis 
should catch this one easily.

Ted Kremenek aec2b6e360 Added comments to ObjCMessageExpr.

Chris Lattner d4b2a67cf3 don't randomly miscompile seto/setuo just because we are in 
ffastmath mode.  This fixes rdar://5902801, a miscompilation
of gcc.dg/builtins-8.c.

Bill, please pull this into Tak.

Chris Lattner bb41aab426 1) add '-debug' output 
2) Return NULL instead of false in several places for tidiness.

Chris Lattner b9b5d6ddaa Delete the IPO simplify-libcalls and completely reimplement it as 
a FunctionPass.  This makes it simpler, fixes dozens of bugs, adds
a couple of minor features, and shrinks is considerably: from
2214 to 1437 lines.
