Fariborz Jahanian a591a12ea5 Allow property in base class to be implemented in a 
derived class.

 2008-04-21 23:57:08 +00:00
Ted Kremenek efa92f1dfc Added missing expected-warning. 
llvm-svn: 50073
 2008-04-21 23:45:26 +00:00
Ted Kremenek 503924bb9c Added null dereference test case looking for null dereferences involving MemberExpr. 
llvm-svn: 50072
 2008-04-21 23:44:17 +00:00
Ted Kremenek 38213f9573 Added support for detected bad dereferences involving MemberExprs, e.g. x->f where "x" is NULL. 
llvm-svn: 50071
 2008-04-21 23:43:38 +00:00

llvm-svn: 50066
 2008-04-21 21:58:05 +00:00
Fariborz Jahanian c6bec7b6dc More semantics checks of properties. Property implementation can implicitly use 
ivar of same name. 
Better diagnostics to bring home this point.

 2008-04-21 19:48:48 +00:00
Fariborz Jahanian a054e99fa8 Continuation of work on ObjC2's properties. 
Added iterators, methods to find property and categories.
Use them in doing semantic analysis on property implementation
declarations. Fixed typos.

llvm-svn: 50050

Owen Anderson 2988ccad6a Use GVN in LTO instead of GCSE+LoadVN. 
llvm-svn: 50036
 2008-04-21 07:51:07 +00:00
Owen Anderson a5b96ecef9 Remove unneeded #include's. 
llvm-svn: 50035
 2008-04-21 07:47:38 +00:00
Owen Anderson 6a7355caa2 Refactor memcpyopt based on Chris' suggestions. Consolidate several functions 
and simplify code that was fallout from the separation of memcpyopt and gvn.

llvm-svn: 50034
 2008-04-21 07:45:10 +00:00
Duncan Sands 5429033c03 Fix a "large integer implicitly truncated to unsigned type" 
warning.

llvm-svn: 50033
 2008-04-21 07:35:28 +00:00
Chris Lattner 00cab5b9a6 don't print dominators every time it is computed with -debug. 
llvm-svn: 50032
 2008-04-21 06:19:02 +00:00
Chris Lattner d5fbc8f0af another bug introduced in r47802 by nicholas, for no apparent reason. 
llvm-svn: 50031
 2008-04-21 06:12:55 +00:00
Chris Lattner a89143f1e0 Add an ugly note. 
llvm-svn: 50029
 2008-04-21 04:46:30 +00:00
Chris Lattner 0645b88852 Add jump threading to liblto. 
llvm-svn: 50028
 2008-04-21 04:31:40 +00:00
Chris Lattner ba994f7cdf run the jump threading pass in llvm-ld also 
llvm-svn: 50027
 2008-04-21 04:28:40 +00:00
Chris Lattner b15e1f963d enable jump threading pass by default. This causes no miscompilations 
and can significantly shrinkify some code, particularly from C++ land.

llvm-svn: 50025
 2008-04-21 04:22:09 +00:00
Chris Lattner 67bec133b2 fix a bug introduced by Nicholas' "unwinds to" stuff: we 
lost newlines between blocks.

llvm-svn: 50024
 2008-04-21 04:20:33 +00:00
Chris Lattner ad0d42ba15 don't assume that the argument passed to fprintf("%s" is a string. This 
fixes a crash in opt on 433.milc.

llvm-svn: 50023

Chris Lattner f6236cc2e9 Use the new SplitBlockPredecessors to implement a todo. 
llvm-svn: 50022

Douglas Gregor 89f238cbe1 Clean up handling of function redeclarations 
llvm-svn: 50021
 2008-04-21 02:02:58 +00:00
Chris Lattner a5b11705b6 Move SplitBlockPredecessors out of loopsimplify into BasicBlockUtils.h 
as a global helper function.  At the same type, switch it from taking
a vector of predecessors to an arbitrary sequential input.  This allows
us to switch LoopSimplify to use a SmallVector for various temporary
vectors that it passed into SplitBlockPredecessors.

llvm-svn: 50020
 2008-04-21 01:28:02 +00:00
Chris Lattner d418b06abf Move domtree/frontier updating earlier, allowing us to use it to update phi 
nodes, removing a hack.

llvm-svn: 50019
 2008-04-21 01:05:08 +00:00
Chris Lattner 96e9e22269 Factor dominator tree and frontier updating into SplitBlockPredecessors 
instead of doing it after every call.

llvm-svn: 50018
 2008-04-21 00:54:38 +00:00
Chris Lattner 559c867ece fit some more code in 80 cols.

llvm-svn: 50008
 2008-04-20 23:39:44 +00:00
Nicolas Geoffray 984e7199cc Don't forget to update the current operand when getting the size of an instruction. 
llvm-svn: 50007
 2008-04-20 23:36:47 +00:00
Chris Lattner ff1c6e388c finish the first cut of a jump threading pass implementation. 
llvm-svn: 50006
 2008-04-20 22:39:42 +00:00
Chris Lattner 567166c0a8 replace a slow and verbose version of Instruction::isUsedOutsideOfBlock with 
a call to Instruction::isUsedOutsideOfBlock.

llvm-svn: 50005
 2008-04-20 22:18:22 +00:00
Chris Lattner 8ec6e8af60 add a handy helper method to instruction, useful for determining 
whether it is used outside of some block.  This can be used to see
if there are any non-local references, for example.

llvm-svn: 50004
 2008-04-20 22:11:30 +00:00
Chris Lattner 9c1f1a82bf we can only thread blocks when there is a pred we can determine the succ of. 
llvm-svn: 50003
 2008-04-20 21:18:09 +00:00
Chris Lattner 2115722ffa improve comments, infrastructure, and add some validity checks for threading. 
Add a cost function.

Implement feedback from Chris re: PR1998

llvm-svn: 50001
 2008-04-20 20:38:08 +00:00
Chris Lattner b3b6007c8b Add a new Jump Threading pass, which will handle cases 
such as those in PR2235.  Right now the pass is not very
effective. :)

Chris Lattner 912bec79ca hopefully resolve PR2240 
llvm-svn: 49999
 2008-04-20 19:59:12 +00:00
Chris Lattner 14cd1ee95f Two improvements to initializer parsing: 
1. If we hit a semantic error, try harder to recover to emit
   diagnostics for later initializer errors (PR2241).
2. Don't leak parsed initializers on an error.
