2012-09-14Cortex-A9 instruction-level scheduling machine model.Andrew Trick
This models the A9 processor at the level of instruction operands, as opposed to the itinerary, which models each operation at the level of pipeline stages. The two primary motivations are: 1) Allow MachineScheduler to model A9 as an out-of-order processor. It can now distinguish between hazards that force interlocking vs. buffered resources. 2) Reduce long-term maintenance by allowing the itinerary and target hooks to eventually be removed. Note that almost all of the complexity in the new model exists to model instruction variants, which the itinerary cannot handle. Instead the scheduler previously relied on processor-specific target hooks which are incomplete and buggy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163921 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-13Don't fold indexed loads into TCRETURNmi64.Jakob Stoklund Olesen
We don't have enough GR64_TC registers when calling a varargs function with 6 arguments. Since %al holds the number of vector registers used, only %r11 is available as a scratch register. This means that addressing modes using both base and index registers can't be folded into TCRETURNmi64. <rdar://problem/12282281> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163761 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-12This patch corrects logic in PPCFrameLowering for save and restore of ↵Roman Divacky
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. Patch by William J. Schmidt! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163713 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-11Add TRI::getSubRegIndexLaneMask().Jakob Stoklund Olesen
Sub-register lane masks are bitmasks that can be used to determine if two sub-registers of a virtual register will overlap. For example, ARM's ssub0 and ssub1 sub-register indices don't overlap each other, but both overlap dsub0 and qsub0. The lane masks will be accurate on most targets, but on targets that use sub-register indexes in an irregular way, the masks may conservatively report that two sub-register indices overlap when the eventually allocated physregs don't. Irregular register banks also mean that the bits in a lane mask can't be mapped onto register units, but the concept is similar. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163630 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-11Reorganize MachineScheduler interfaces and publish them in the header.Andrew Trick
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163580 91177308-0d34-0410-b5e6-96231b3b80d8
