Dan Gohman 3e2225dfd6 Factor the code for determining the target-specific instruction 
namespace out of the isel emitters and into common code.

Dan Gohman 814f291664 Move the handling of ANY_EXTEND, SIGN_EXTEND_INREG, and TRUNCATE 
out of X86ISelDAGToDAG.cpp C++ code and into tablegen code.
Among other things, using tablegen for these things makes them
friendlier to FastISel.

Tablegen can handle the case of i8 subregs on x86-32, but currently
the C++ code for that case uses MVT::Flag in a tricky way, and it
happens to schedule better in some cases. So for now, leave the
C++ code in place to handle the i8 case on x86-32.

llvm-svn: 55077
 2008-08-20 21:10:53 +00:00
Dan Gohman 02c84b8910 Simplify FastISel's constructor argument list, make the FastISel 
class hold a MachineRegisterInfo member, and make the
MachineBasicBlock be passed in to SelectInstructions rather
than the FastISel constructor.

 2008-08-20 17:19:58 +00:00
Ted Kremenek e5edbdd4ee Patch by Zhongxing Xu: 
This patch moves some code in GRStateManager::RemoveDeadBindings() to EnvironmentManager::RemoveDeadBindings().

llvm-svn: 55064
 2008-08-20 17:08:29 +00:00
Chris Lattner 1ac3e2545b Move the fast-path (<=i64) cases of various APInt methods inline 
and the slow-path cases out of line.  This speeds up instcombine
a bit in real world cases.  Patch contributed by m-s.

Ted Kremenek eb38fde5e5 Patch by Zhongxing Xu: We should set back the modified ConstEq map.

 2008-08-20 16:30:28 +00:00
Dan Gohman 2da2bedc72 Change the FoldingSetNodeID usage for objects which carry 
alignment and volatility information, such as loads and
stores, to reduce the number of integer values added to
the FoldingSetNodeID.

llvm-svn: 55058

Dan Gohman 3ad7e96f8a Clean up a dead return missed in r55055. 
llvm-svn: 55057
 2008-08-20 15:54:46 +00:00
Dan Gohman 8823b0d245 Tablegen generated code already tests the opcode value, so it's not 
necessary to use dyn_cast in these predicates.

llvm-svn: 55055
 2008-08-20 15:24:22 +00:00
Dan Gohman f6aa60ff71 Use BitVector instead of std::vector<unsigned char>.

Eli Friedman f05b7728b3 Class reorg for ARM. Shouldn't be any visible changes. 
llvm-svn: 55042
 2008-08-20 07:44:10 +00:00
Eli Friedman da8f5a9bd8 Class hierarchy reorg for Sparc architecture. While I was there, I 
cleaned it up a bit, including fixing the definition of va_list; this
shouldn't break anything, but anyone using Sparc should watch for 
regressions.

Daniel Dunbar 94834d8883 Fix subtle bug introduced in r54852. 
- UsualUnaryConversions takes an Expr *& and may modify its argument,
   this broke when it was refactored into Sema::CheckCastTypes. This
   meant that we were missing implicit casts in some places.
 - Seems pretty sad that this got through our tests.

llvm-svn: 55039

Ted Kremenek 821159e352 Re-enable deletion of AST nodes upon completion of ParseAST. 
llvm-svn: 55038
 2008-08-20 03:27:00 +00:00
Ted Kremenek 0e857200bb Added ObjCAtDefsFieldDecl to represent FieldDecls created by @defs. 
This fixes an ownership issue where FieldDecls could be owned both by an ObjCInterfaceDecl and a RecordDecl.

llvm-svn: 55037
 2008-08-20 03:26:33 +00:00
Eli Friedman 3fd920afce Reorganize the class hierarchy for x86 targets; shouldn't have any 
visible effects, but this will significantly reduce the amount of 
boilerplate code necessary to add subtargets.

If this looks okay, I'll do the rest of the processors (PPC, Sparc, ARM) 
soon.

llvm-svn: 55029
 2008-08-20 00:48:50 +00:00
Dan Gohman 847ebb90b8 Add support for running SelectionDAG if FastISel fails. This is under 
a command-line option, so that the default behavior is an abort, which
is useful for exposing code that isn't supported yet.

Daniel Dunbar 66912a1a6d Move all Obj-C runtime interaction into CodeGenFunction.

 - Add EmitObjCProtocolExpr to CodeGenFunction.

Bill Wendling f00f3055d8 Revert r55018 and apply the correct "fix" for the 64-bit sub_and_fetch atomic. 
Just expand it like the other X-bit sub_and_fetches.
