Roman Divacky [Wed, 12 Sep 2012 14:47:47 +0000 (14:47 +0000)]
This patch corrects logic in PPCFrameLowering for save and restore of
nonvolatile condition register fields across calls under the SVR4 ABIs.

 * With the 64-bit ABI, the save location is at a fixed offset of 8 from
the stack pointer.  The frame pointer cannot be used to access this
portion of the stack frame since the distance from the frame pointer may
change with alloca calls.

 * With the 32-bit ABI, the save location is just below the general
register save area, and is accessed via the frame pointer like the rest
of the save areas.  This is an optional slot, so it must only be created
if any of CR2, CR3, and CR4 were modified.

 * For both ABIs, save/restore logic is generated only if one of the
nonvolatile CR fields were modified.

I also took this opportunity to clean up an extra FIXME in
PPCFrameLowering.h.  Save area offsets for 32-bit GPRs are meaningless
for the 64-bit ABI, so I removed them for correctness and efficiency.

Fixes PR13708 and partially also PR13623. It lets us enable exception handling
on PPC64.

Reorganize MachineScheduler interfaces and publish them in the header.

The Hexagon target decided to use a lot of functionality from the
target-independent scheduler. That's fine, and other targets should be
able to do the same. This reorg and API update makes that easy.

For the record, ScheduleDAGMI was not meant to be subclassed. Instead,
new scheduling algorithms should be able to implement
MachineSchedStrategy and be done. But if need be, it's nice to be
able to extend ScheduleDAGMI, so I also made that easier. The target
scheduler is somewhat more apt to break that way though.

LiveVariables: Compute a set of defs and kills to speed up updating LV during critical edge splitting.

Previously we checked if the register is def'd in a block via the def/use list a
nd walked the list of kills to check if the register is killed in a block. Both
of these checks can be made much cheaper by walking the block first and
recording all defs and kills.

This reduces the compile time of the test case from PR13651 from 40s to 15s at
-O2. The compile time is still dominated by LV updating but now the main culprit
is SparseBitVector's slowness.
