Jay Foad 0745e645e0 Remove some unnecessary includes of PseudoSourceValue.h. 
llvm-svn: 144631
 2011-11-15 07:24:32 +00:00
Pete Cooper 82cd9e81fc Added invariant field to the DAG.getLoad method and changed all calls. 
When this field is true it means that the load is from constant (runt-time or compile-time) and so can be hoisted from loops or moved around other memory accesses

llvm-svn: 144100
 2011-11-08 18:42:53 +00:00
Dan Gohman 2c9bda1512 Remove the explicit request for "Latency" scheduling from MSP430, 
as the Latency scheduler is going away.

Duncan Sands f2641e1bc1 Add codegen support for vector select (in the IR this means a select 
with a vector condition); such selects become VSELECT codegen nodes.
This patch also removes VSETCC codegen nodes, unifying them with SETCC
nodes (codegen was actually often using SETCC for vector SETCC already).
This ensures that various DAG combiner optimizations kick in for vector
comparisons.  Passes dragonegg bootstrap with no testsuite regressions
(nightly testsuite as well as "make check-all").  Patch mostly by
Nadav Rotem.

Chris Lattner 229907cd11 land David Blaikie's patch to de-constify Type, with a few tweaks.

Eric Christopher 0713a9d8fc Add a parameter to CCState so that it can access the MachineFunction. 
No functional change.

Part of PR6965

Chris Lattner 3e5fbd74ed rename MVT::Flag to MVT::Glue. "Flag" is a terrible name for 
something that just glues two nodes together, even if it is
sometimes used for flags.

Duncan Sands f5dda01f33 Inside the calling convention logic LocVT is always a simple 
value type, so there is no point in passing it around using
an EVT.  Use the simpler MVT everywhere.  Rather than trying
to propagate this information maximally in all the code that
using the calling convention stuff, I chose to do a mainly
low impact change instead.

Chris Lattner 676c61db0e update a bunch of code to use the MachinePointerInfo version of getStore. 
llvm-svn: 114461
 2010-09-21 18:41:36 +00:00
Chris Lattner 7727d05dbb convert the targets off the non-MachinePointerInfo of getLoad.

Dan Gohman fe7532a308 Split the SDValue out of OutputArg so that SelectionDAG-independent 
code can do calling-convention queries. This obviates OutputArgReg.

Dan Gohman 3439629239 Reapply r107655 with fixes; insert the pseudo instruction into 
the block before calling the expansion hook. And don't
put EFLAGS in a mbb's live-in list twice.

Dan Gohman 12205645a6 Fix a bunch of custom-inserter functions to handle the case where 
the pseudo instruction is not at the end of the block.

Evan Cheng 0664a67fe1 Remove isSS argument from CreateFixedObject. Fixed objects cannot be spill slots so it's always false. 
llvm-svn: 107550

Evan Cheng 738e920edf Code refactoring: pull SchedPreference enum from TargetLowering.h to TargetMachine.h and put it in its own namespace.

Dan Gohman 25c1653700 Get rid of the EdgeMapping map. Instead, just check for BasicBlock 
changes before doing phi lowering for switches.

llvm-svn: 102809
 2010-05-01 00:01:06 +00:00
Dan Gohman 21cea8ac2e Use const qualifiers with TargetLowering. This eliminates several 
const_casts, and it reinforces the design of the Target classes being
immutable.

SelectionDAGISel::IsLegalToFold is now a static member function, because
PIC16 uses it in an unconventional way. There is more room for API
cleanup here.

And PIC16's AsmPrinter no longer uses TargetLowering.

Anton Korobeynikov e96503faa1 IT turns out that during jumpless setcc lowering eq and ne were swapped. 
This fixes PR6348

Anton Korobeynikov ab663a0bfe Move TLOF implementations to libCodegen to resolve layering violation. 
llvm-svn: 96288

David Greene 27d044d65d Remove an assumption of default arguments. This is in anticipation of a 
change to SelectionDAG build APIs.

Duncan Sands 9dff9bec31 Uniformize the names of type predicates: rather than having isFloatTy and 
isInteger, we now have isFloatTy and isIntegerTy.  Requested by Chris!

Evan Cheng c1b0116ff1 Pass callsite return type to TargetLowering::LowerCall and use that to check sibcall eligibility. 
llvm-svn: 95130
 2010-02-02 21:29:10 +00:00
Evan Cheng 67a69dd2ed Eliminate target hook IsEligibleForTailCallOptimization. 
Target independent isel should always pass along the "tail call" property. Change
target hook LowerCall's parameter "isTailCall" into a refernce. If the target
decides it's impossible to honor the tail call request, it should set isTailCall
to false to make target independent isel happy.

Anton Korobeynikov a6450df92a zext / truncate is free on msp430. Inform codegen about this.

 2010-01-15 21:18:18 +00:00
Anton Korobeynikov 6826ce7e96 Add micro-optimization which allows us to fold imm into cmp. This allows us to save 1 word (sometimes) and reduce register pressure. 
llvm-svn: 93551
 2010-01-15 21:18:02 +00:00
Anton Korobeynikov cefa7addc8 Fix cmp emission on msp430: we definitely should turn stuff like 
"icmp lhs, rhs" into "cmp rhs, lhs". This should fix PR5979.

llvm-svn: 93496

Anton Korobeynikov d8f320947f Implement variable-width shifts. 
No testcase yet - it seems we're exposing generic codegen bugs.

Anton Korobeynikov e27e028cdd Lower setcc branchless, if this is profitable.

llvm-svn: 90737
 2009-12-07 02:27:08 +00:00
Anton Korobeynikov abdf86d2be Minor optimization: when doing eq/ne comparions and RHS is a constant - swap operands, this will allow us to fold imm into comparison. 
llvm-svn: 89574

Anton Korobeynikov a9c7bb724a Use 2-byte alignment for functions. 4 bytes are clear overkill here. 
llvm-svn: 89572
 2009-11-22 01:13:39 +00:00
David Greene 1fbe054450 Add a bool flag to StackObjects telling whether they reference spill 
slots.  The AsmPrinter will use this information to determine whether to
print a spill/reload comment.

Remove default argument values.  It's too easy to pass a wrong argument
value when multiple arguments have default values.  Make everything
explicit to trap bugs early.

Update all targets to adhere to the new interfaces..
