Steve Naroff 25449a5221 Fix <rdar://problem/5986833> clang on xcode: incompatible type returning 'void', expected 'int'. 
- Changed Sema::ObjCActOnStartOfMethodDef() to more accurately type "self" in factory methods.
- Changed Sema::ActOnInstanceMessage() to use the new type to restrict the lookup.

Zhou Sheng c775e462a8 Add a test case for opt -instcombine bug fix in revision 52003. 
llvm-svn: 52004
 2008-06-05 14:25:11 +00:00
Zhou Sheng fbe1dc240c If BitWidth equals to ShtAmt, the RHSKnownZero[BitWidth-ShiftAmt-1] will 
crash the opt. Just fix this.

Test case in llvm/test/Transforms/InstCombine/2008-06-05-ashr-crash.ll

Steve Naroff f9c65246dd Fix <rdar://problem/5987482> clang on xcode: null dereference in Sema::ActOnMemberReferenceExpr. 
In addition to fixing the crasher, this commit fixes further improves property lookup (by searching protocols of qualified interfaces..."NSObject <prot>").

Zhou Sheng 3f8de8b130 Add a test case for APInt bug fix in r51999. 
llvm-svn: 52000
 2008-06-05 13:42:21 +00:00
Zhou Sheng 1247c07742 As comments said, for negative value, the arithmetic 
over-shift-right should return -1. So here it should be signed-extended,
when bitwidth larger than 64.

test case: llvm/test/ExecutionEngine/2008-06-05-APInt-OverAShr.ll

Matthijs Kooijman 812989b147 Learn ScalarReplAggregrates how stores and loads of first class aggregrates 
work and how to replace them into individual values. Also, when trying to
replace an aggregrate that is used by load or store with a single (large)
integer, don't crash (but don't replace the aggregrate either).

Also adds a testcase for both structs and arrays.

Matthijs Kooijman e0c5adc158 Let StructRetPromotion check if all if its users are really calls or invokesn, 
not other instructions. This fixes a crash with the added testcase.

llvm-svn: 51992
 2008-06-05 08:57:20 +00:00
Matthijs Kooijman 463f86639d Let StructRetPromotion check if it's users are really calling it and not 
passing its pointer. Fixes test with added testcase.

 2008-06-05 08:48:32 +00:00
Matthijs Kooijman 230d6fbfeb Use use_iterator::getOperandNo instead of CallSite::hasArgument to check if a 
function is passed as an argument instead of called. Also do this check a bit
earlier.

llvm-svn: 51990
 2008-06-05 08:34:25 +00:00

 2008-06-05 04:33:44 +00:00
Steve Naroff cfdf6166fc Support "<p>" as a short-hand for "id<p>". Here's a comment from GCC (the only documentation I could find on it). 
/* Make "<SomeProtocol>" equivalent to "id <SomeProtocol>" - nisse@lysator.liu.se.  */

This commit adds the parser magic. The type associated with <p> is still incorrect. Will discuss with Chris.

Evan Cheng 976b1eee81 Fix a memcpy lowering bug. Even though the memcpy alignment is smaller than the desired alignment, the frame destination alignment may still be larger than the desired alignment. Don't change its alignment to something smaller.
