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

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 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.

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.

Dan Gohman 73caf5ff10 Change PMTopLevelManager's PassManagers vector element type from 
Pass* to PMDataManager*. PMDataManager is more specific than Pass,
so this more accurately describes the objects that are being stored.

This eliminates the need for several dynamic_casts to PMDataManager*.
It does introduce one dynamic_cast though, in dumpPasses(). Give
this one a comment describing why a dynamic_cast is being used.

Dale Johannesen 6424bd0b11 Do not promote float params to double in varargs 
calls here.  This was done earlier for params in
the varargs part of the params; any float params
that survive to here are in the non-varargs part,
and must not be promoted.

Steve Naroff 35cb7960e3 Two fixes to RewriteTest::RewriteObjCIvarRefExpr(): 
- For explicit ivar refers, make sure the cast is propagated to the AST.
- Don't free the base (since it is still in use).
This fixes the recent regression to test/Rewriter/objc-ivar-receiver-1.m.

Evan Cheng 65e9d5f1a8 Experimental scheduler change to schedule / coalesce the copies added for function livein's. Take 2008-03-10-RegAllocInfLoop.ll, the schedule looks like this after these copies are inserted: 
entry: 0x12049d0, LLVM BB @0x1201fd0, ID#0:
Live Ins: %EAX %EDX %ECX
        %reg1031<def> = MOVPC32r 0
        %reg1032<def> = ADD32ri %reg1031, <es:_GLOBAL_OFFSET_TABLE_>, %EFLAGS<imp-def>
        %reg1028<def> = MOV32rr %EAX
        %reg1029<def> = MOV32rr %EDX
        %reg1030<def> = MOV32rr %ECX
        %reg1027<def> = MOV8rm %reg0, 1, %reg0, 0, Mem:LD(1,1) [0x1201910 + 0]
        %reg1025<def> = MOV32rr %reg1029
        %reg1026<def> = MOV32rr %reg1030
        %reg1024<def> = MOV32rr %reg1028

The copies unnecessarily increase register pressure and it will end up requiring a physical register to be spilled.

With -schedule-livein-copies:
entry: 0x12049d0, LLVM BB @0x1201fa0, ID#0:
Live Ins: %EAX %EDX %ECX
        %reg1031<def> = MOVPC32r 0
        %reg1032<def> = ADD32ri %reg1031, <es:_GLOBAL_OFFSET_TABLE_>, %EFLAGS<imp-def>
        %reg1024<def> = MOV32rr %EAX
        %reg1025<def> = MOV32rr %EDX
        %reg1026<def> = MOV32rr %ECX
        %reg1027<def> = MOV8rm %reg0, 1, %reg0, 0, Mem:LD(1,1) [0x12018e0 + 0]

Much better!

Ted Kremenek e2f6d6cdb8 Changed CallRetValSymbol to SymbolConjured to allow "conjured" symbols to be created for any expression, not just CallExprs. 
Added experimental support for conjuring symbols during assingments where the RHS is "unknown".  This allows more value tracking for path-sensitivity.
Fixed bug in "assumption" logic when processing symbolic constraints; we would improperly mark constraints we didn't support as infeasible.

Duncan Sands 723849a17f Initial soft-float support for LegalizeTypes. I rewrote 
the fcopysign expansion from LegalizeDAG to get rid of
what seems to be a bug: the use of sign extension means
that when copying the sign bit from an f32 to an f64,
the upper 32 bits of the f64 (now an i64) are set, not
just the top bit...  I also generalized it to work for
any sized floating point types, and removed the bogosity:
  SDOperand Mask1 = (SrcVT == MVT::f64)
    ? DAG.getConstantFP(BitsToDouble(1ULL << 63), SrcVT)
    : DAG.getConstantFP(BitsToFloat(1U << 31), SrcVT);
  Mask1 = DAG.getNode(ISD::BIT_CONVERT, SrcNVT, Mask1);
(here SrcNVT is an integer with the same size as SrcVT).
As far as I can see this takes a 1 << 63, converts to
a double, converts that to a floating point constant
then converts that to an integer constant, ending up
with... 1 << 63 as an integer constant!  So I just
generate this integer constant directly.

Steve Naroff 9f33bd2c34 Avoid using the "unnamed struct field" extension (enabled with -fms-extensions). This feature/extension silently does the wrong thing in g++. As far as I can tell, g++ simply throws the field away entirely (note that it works fine with gcc). Since I am now always casting the object (for other reasons), accessing protected/public fields simply requires the cast refer to the defining class. This solution is simpler all around (thanks to Chris for suggesting it).
