Use the new script to sort the includes of every file under lib. Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8

Make the LiveRegMatrix analysis available to targets. No functional change, just moved header files. Targets can inject custom passes between register allocation and rewriting. This makes it possible to tweak the register allocation before rewriting, using the full global interference checking available from LiveRegMatrix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168806 91177308-0d34-0410-b5e6-96231b3b80d8

Don't store COPY pointers in VNInfo. If a value is defined by a COPY, that instuction can easily and cheaply be found by getInstructionFromIndex(VNI->def).

Rename SlotIndexes to match how they are used. The old naming scheme (load/use/def/store) can be traced back to an old linear scan article, but the names don't match how slots are actually used. The load and store slots are not needed after the deferred spill code insertion framework was deleted. The use and def slots don't make any sense because we are using half-open intervals as is customary in C code, but the names suggest closed intervals. In reality, these slots were used to distinguish early-clobber defs from normal defs. The new naming scheme also has 4 slots, but the names match how the slots are really used. This is a purely mechanical renaming, but some of the code makes a lot more sense now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144503 91177308-0d34-0410-b5e6-96231b3b80d8

Teach TargetRegisterInfo how to cram stack slot indexes in with the virtual and physical register numbers.

Begin implementation of an inline spiller. InlineSpiller inserts loads and spills immediately instead of deferring to VirtRegMap.

Added a new "splitting" spiller. When a call is placed to spill an interval this spiller will first try to break the interval up into its component values. Single value intervals and intervals which have already been split (or are the result of previous splits) are spilled by the default spiller. Splitting intervals as described above may improve the performance of generated code in some circumstances. This work is experimental however, and it still miscompiles many benchmarks. It's not recommended for general use yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90951 91177308-0d34-0410-b5e6-96231b3b80d8

Added a new Spiller implementation which wraps LiveIntervals::addIntervalsForSpills. All spiller calls in RegAllocLinearScan now go through the new Spiller interface. The "-new-spill-framework" command line option has been removed. To use the trivial in-place spiller you should now pass "-spiller=trivial -rewriter=trivial". (Note the trivial spiller/rewriter are only meant to serve as examples of the new in-place modification work. Enabling them will yield terrible, though hopefully functional, code). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89311 91177308-0d34-0410-b5e6-96231b3b80d8

The Indexes Patch. This introduces a new pass, SlotIndexes, which is responsible for numbering instructions for register allocation (and other clients). SlotIndexes numbering is designed to match the existing scheme, so this patch should not cause any changes in the generated code. For consistency, and to avoid naming confusion, LiveIndex has been renamed SlotIndex. The processImplicitDefs method of the LiveIntervals analysis has been moved into its own pass so that it can be run prior to SlotIndexes. This was necessary to match the existing numbering scheme. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85979 91177308-0d34-0410-b5e6-96231b3b80d8

Improved tracking of value number kills. VN kills are now represented as an (index,bool) pair. The bool flag records whether the kill is a PHI kill or not. This code will be used to enable splitting of live intervals containing PHI-kills. A slight change to live interval weights introduced an extra spill into lsr-code-insertion (outside the critical sections). The test condition has been updated to reflect this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75097 91177308-0d34-0410-b5e6-96231b3b80d8

It has finally happened. Spiller is now using live interval info. This fixes a very subtle bug. vr defined by an implicit_def is allowed overlap with any register since it doesn't actually modify anything. However, if it's used as a two-address use, its live range can be extended and it can be spilled. The spiller must take care not to emit a reload for the vn number that's defined by the implicit_def. This is both a correctness and performance issue. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69743 91177308-0d34-0410-b5e6-96231b3b80d8

Teach spiller to unfold instructions which modref spill slot when a scratch register is available and when it's profitable. e.g. xorq %r12<kill>, %r13 addq %rax, -184(%rbp) addq %r13, -184(%rbp) ==> xorq %r12<kill>, %r13 movq -184(%rbp), %r12 addq %rax, %r12 addq %r13, %r12 movq %r12, -184(%rbp) Two more instructions, but fewer memory accesses. It can also open up opportunities for more optimizations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69341 91177308-0d34-0410-b5e6-96231b3b80d8

When assigning a physical register to a MachineOperand, set the subreg field to 0, since the subreg field is only used for virtual register subregs. This doesn't change current functionality; it just eliminates bogus noise from debug output. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68955 91177308-0d34-0410-b5e6-96231b3b80d8

Fix pr3954. The register scavenger asserts for inline assembly with register destinations that are tied to source operands. The TargetInstrDescr::findTiedToSrcOperand method silently fails for inline assembly. The existing MachineInstr::isRegReDefinedByTwoAddr was very close to doing what is needed, so this revision makes a few changes to that method and also renames it to isRegTiedToUseOperand (for consistency with the very similar isRegTiedToDefOperand and because it handles both two-address instructions and inline assembly with tied registers). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68714 91177308-0d34-0410-b5e6-96231b3b80d8

Spiller may unfold load / mod / store instructions as an optimization when the would be loaded value is available in a register. It needs to check if it's legal to clobber the register. Also, the register can contain values of multiple spill slots, make sure to check all instead of just the one being unfolded. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67068 91177308-0d34-0410-b5e6-96231b3b80d8
