Anton Korobeynikov 2fd24e7713 Reapply 55899: First draft of EH support on x86/64-linux
Now with fix, which prevents subtle codegen bug to trigger on darwin.
No fix for bug though, it's still there.

Bill Wendling 5f7371d7b1 Revert my previous change -- the subtraction of two constants was a no-op
before. This is taken care of in the selection DAG pass. In my opinion, this
should be in one place or the other. I.e., it should probably be removed from
the DAG combiner (along with the other arithmetic transformations on constants
that are essentially no-ops).

Duncan Sands 95c2a7848a When PruneEH turned an invoke into an ordinary
call (thus changing the call site) it didn't
inform the callgraph about this.  But the
call site does matter - as shown by the testcase,
the callgraph become invalid after the inliner
ran (with an edge between two functions simply
missing), resulting in wrong deductions by
GlobalsModRef.

Duncan Sands 9e23602849 Delete the removeCallEdgeTo callgraph method,
because it does not maintain a correct list
of callsites.  I discovered (see following
commit) that the inliner will create a wrong
callgraph if it is fed a callgraph with
correct edges but incorrect callsites.  These
were created by Prune-EH, and while it wasn't
done via removeCallEdgeTo, it could have been
done via removeCallEdgeTo, which is an accident
waiting to happen.  Use removeCallEdgeFor
instead.

Evan Cheng 6c94b99c62 For whatever the reason, x86 CallingConv::Fast (i.e. fastcc) was not passing scalar arguments in registers. This patch defines a new fastcc CC which is slightly different from the FastCall CC. In addition to passing integer arguments in ECX and EDX, it also specify doubles are passed in 8-byte slots which are 8-byte aligned (instead of 4-byte aligned). This avoids a potential performance hazard where doubles span cacheline boundaries.

Dan Gohman c7367b4546 Fix addRegisterDead and addRegisterKilled to be more thorough
when searching for redundant subregister dead/kill bits.

Previously it was common to see instructions marked like this:
  "RET %EAX<imp-use,kill>, %AX<imp-use,kill>"

With this change, addRegisterKilled continues scanning after
finding the %EAX operand, so it proceeds to discover the
redundant %AX kill and eliminates it, producing this:
  "RET %EAX<imp-use,kill>"

This currently has no effect on the generated code.

Duncan Sands 130d9efec3 Add a small pass that sets the readnone/readonly
attributes on functions, based on the result of
alias analysis.  It's not hardwired to use
GlobalsModRef even though this is the only (AFAIK)
alias analysis that results in this pass actually
doing something.  Enable as follows:
  opt ... -globalsmodref-aa -markmodref ...
Advantages of this pass: (1) records the result
of globalsmodref in the bitcode, meaning it is
available for use by later passes (currently
the pass manager isn't smart enough to magically
make an advanced alias analysis available to all
later passes), which may expose more optimization
opportunities; (2) hopefully speeds up compilation
when code is optimized twice, for example when a
file is compiled to bitcode, then later LTO is done
on it: marking functions readonly/readnone when
producing the initial bitcode should speed up alias
analysis during LTO; (3) good for discovering that
globalsmodref doesn't work very well :)
Not currently turned on by default.

Bill Wendling aebd2662d3 Revert the "XFAIL" for the rotate_ops.ll testcase. Instead, mark ISD::ROTR
instructions in CellSPU as "Expand" so that they won't be generated. I added a
"FIXME" so that this hack can be addressed and reverted once ISD::ROTR is
supported in the .td files.

Bill Wendling 91bf1e0dc5 CellSPU doesn't appear to support fully the "ISD::ROTR" operation. The DAG
combiner can now generate ROTR if the backend says that it can handle it. Cell
SPU says this, but gets an error from code gen saying that it can't select
ROTR. I'm xfailing this test until this can be fixed.

Bill Wendling fc72416447 - Fix comment so that it describes how the code really works:
// fold (or (shl x, (*ext y)), (srl x, (*ext (sub 32, y)))) ->
   //   (rotl x, y)
   // fold (or (shl x, (*ext y)), (srl x, (*ext (sub 32, y)))) ->
   //   (rotr x, (sub 32, y))

Example: (x == 0xDEADBEEF and y == 4)

    (x << 4) | (x >> 28)
 => 0xEADBEEF0 | 0x0000000D
 => 0xEADBEEFD

    (rotl x, 4)
 => 0xEADBEEFD

    (rotr x, 28)
 => 0xEADBEEFD

- Fix comment and code for second version. It wasn't using the rot* propertly.

   // fold (or (shl x, (*ext (sub 32, y))), (srl x, (*ext r))) -> 
   //   (rotr x, y)
   // fold (or (shl x, (*ext (sub 32, y))), (srl x, (*ext r))) ->
   //   (rotl x, (sub 32, y))

    (x << 28) | (x >> 4)
 => 0xD0000000 | 0x0DEADBEE
 => 0xDDEADBEE

    (rotl x, 4)
 => 0xEADBEEFD

Owen Anderson 6f0c51d9da Fix an issue where a use might be selected before a def, and then we didn't respect the pre-chosen vreg
assignment when selecting the def.  This is the naive solution to the problem: insert a copy to the pre-chosen
vreg.  Other solutions might be preferable, such as:
  1) Passing the dest reg into FastEmit_.  However, this would require the higher level code to know about reg classes, which they don't currently.
  2) Selecting blocks in reverse postorder.  This has some compile time cost for computing the order, and we'd need to measure its impact.

Dan Gohman f27e33baa7 Optimize DAGCombiner's worklist processing. Previously it started
its work by putting all nodes in the worklist, requiring a big
dynamic allocation. Now, DAGCombiner just iterates over the AllNodes
list and maintains a worklist for nodes that are newly created or
need to be revisited. This allows the worklist to stay small in most
cases, so it can be a SmallVector.

This has the side effect of making DAGCombine not miss a folding

ATOMIC_LOAD_ADD_{8,16,32,64} instead of ATOMIC_LOAD_ADD.
Increased the Hardcoded Constant OpActionsCapacity to match.
Large but boring; no functional change.

This is to support partial-word atomics on ppc; i8 is
not a valid type there, so by the time we get to lowering, the
ATOMIC_LOAD nodes looks the same whether the type was i8 or i32.
The information can be added to the AtomicSDNode, but that is the
largest SDNode; I don't fully understand the SDNode allocation,
but it is sensitive to the largest node size, so increasing
that must be bad.  This is the alternative.

Dan Gohman e1a9a780a5 Reorganize the lifetimes of the major objects SelectionDAGISel
works with.

SelectionDAG, FunctionLoweringInfo, and SelectionDAGLowering
objects now get created once per SelectionDAGISel instance, and
can be reused across blocks and across functions. Previously,
they were created and destroyed each time they were needed.

This reorganization simplifies the handling of PHI nodes, and
also SwitchCases, JumpTables, and BitTestBlocks. This
simplification has the side effect of fixing a bug in FastISel
where successor PHI nodes weren't being updated correctly.

This is also a step towards making the transition from FastISel
into and out of SelectionDAG faster, and also making
plain SelectionDAG faster on code with lots of little blocks.

Dan Gohman d56f73f2f2 Optimize SelectionDAG's topological sort to use one pass instead

llvm-svn: 55377
2008-08-26 18:50:40 +00:00
Owen Anderson 3ea3efec44 We need to check that the return type is correct, even in cases where we don't
have a return type that differs from the operand types.

llvm-svn: 55376
2008-08-26 18:50:00 +00:00
Owen Anderson 27fb3dcbc7 Make TargetInstrInfo::copyRegToReg return a bool indicating whether the copy requested
was inserted or not.  This allows bitcast in fast isel to properly handle the case
where an appropriate reg-to-reg copy is not available.
