Evan Cheng 84aec09fdb Fix PR2138. Apparently any modification to a std::multimap (including remove entries for a different key) can invalidate multimap iterators.

Chris Lattner bb8c2406dc this was removed from the Unix side.

Nate Begeman b561de7455 Correctly error on arrays with automatic storage full of objects with 
non-default address space, and fix comment.
Add a test for this.

Dale Johannesen 0dfd3f33f7 Implement the real calling convention for ppc32 Altivec: 
vectors go at the end of the memory area, after all
non-vector parameters.

Ted Kremenek 7b00d15bc5 Path-sensitive analyses no longer take a FunctionDecl, but any Decl representing 
a block of "code".

Patched various ASTConsumers (such as ASTDumper) to have more support for
processing ObjCMethodDecl. CFGVisitor now builds CFGs for ObjCMethodDecls.

Evan Cheng 96bdbd6c5d Fix a number of encoding bugs. SSE 4.1 instructions MPSADBWrri, PINSRDrr, etc. have 8-bits immediate field (ImmT == Imm8).

Chris Lattner 477d0f5294 Add an issue that is preventing instcombine from doing a simplification. 
llvm-svn: 48356
 2008-03-14 06:00:19 +00:00
Duncan Sands a06e4f3050 Simplify using getIntPtrConstant. 
llvm-svn: 48355
 2008-03-14 05:23:57 +00:00
Bill Wendling 68a930b33e The inst combining of inttoptr into GEP with one index was using the bit size of 
the type instead of the byte size. This was causing troublesome mis-compilations.

True to form, this took 2 days to find and is a one-line fix. :-P

Evan Cheng 3108798ecb Add an MO_Undef MachineOperandType, intended for INSERT_SUBREG. Next up MO_Undead.

Nate Begeman 144625ef9b ISO/IEC TR 18037 
An address space name cannot be used to qualify an object that has automatic
storage duration.  Still not catching ASQual'd allocas of array type, just 
scalars at the moment.

Evan Cheng db443ca377 Livein copy scheduling fixes: do not coalesce physical register copies, correctly determine the safe location to insert the copies.

 2008-03-13 22:13:53 +00:00
Owen Anderson 7a69e3aef3 Fix a bug in GVN that Duncan noticed, where we potentially need to insert a 
pointer bitcast when performing return slot optimization.

Ted Kremenek 1fdd0a480e The LiveVariables analysis no longer requires a FunctionDecl&; this allows it 
to be run on other declarations of blocks of code (e.g., Objective-C methods.)

llvm-svn: 48339

Evan Cheng 442d708bfb New test case.

Evan Cheng 8f8a8b28e9 Don't try to sink 3-address instruction if convertToThreeAddress created more than one instructions. 
llvm-svn: 48336

Evan Cheng ecde45ecb5 A test case I forgot to check in.

Evan Cheng 21449c76bc Remove an unused command line option. 
llvm-svn: 48334
 2008-03-13 06:38:28 +00:00
Evan Cheng 5c26bde55e TwoAddressInstructionPass enhancement. After it converts a two address instruction into a 3-address one, sink it past the instruction that kills the read-mod-write register if its definition is used past the kill. This reduces the number of live register by one.

Chris Lattner fdc0748940 handle __extension__ properly at block scope. 
llvm-svn: 48332
 2008-03-13 06:32:11 +00:00
Chris Lattner b943aa8c6c instead of passing in null end location info, pass in the same as start. 
This still isn't right, but is slightly nicer.

llvm-svn: 48331
 2008-03-13 06:29:54 +00:00
Chris Lattner 2e23209df1 improve DeclStmt to be able to store SourceRange info correctly. 
Set the start of DeclStmt range.  Right now the end is meaningless 
though.

Christopher Lamb dd55d3f1b2 Get rid of a pseudo instruction and replace it with subreg based operation on real instructions, ridding the asm printers of the hack used to do this previously. In the process, update LowerSubregs to be careful about eliminating copies that have side affects. 
Note: the coalescer will have to be careful about this too, when it starts coalescing insert_subreg nodes.

Ted Kremenek b64d183803 Added bandaid support in CFG construction for ObjCForEachStmt and ObjCAtTryStmt: 
we gracefully back out and return NULL for the CFG, allowing clients to skip
analyzing functions with these CFGs. We will add support later.

Modified base ASTConsumer "CFGVisitor" to detect when a CFG is not constructed
and to emit a warning.

Evan Cheng 0ceb8eb150 Improve VarInfo::removeKill() by using std::find instead of linear search. 
llvm-svn: 48321
 2008-03-13 02:42:55 +00:00
Nick Lewycky 7698bfbe16 Update -mem2reg to use succ_iterator instead of iterating across TerminatorInst 
successors. This makes it support nounwind.
