Jakob Stoklund Olesen [Tue, 11 Sep 2012 16:34:08 +0000 (16:34 +0000)]
Add TRI::getSubRegIndexLaneMask().

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.

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.

The assembler can alias one instruction into another based
on the operands. For example the jump instruction "J" takes
and immediate operand, but if the operand is a register the

Michael Liao [Thu, 6 Sep 2012 23:32:48 +0000 (23:32 +0000)]
Re-work bit/bits value resolving in tblgen

- This patch is inspired by the failure of the following code snippet
  which is used to convert enumerable values into encoding bits to
  improve the readability of td files.

  class S<int s> {
    bits<2> V = !if(!eq(s, 8),  {0, 0},
                !if(!eq(s, 16), {0, 1},
                !if(!eq(s, 32), {1, 0},
                !if(!eq(s, 64), {1, 1}, {?, ?}))));
  }

  Later, PR8330 is found to report not exactly the same bug relevant
  issue to bit/bits values.

- Instead of resolving bit/bits values separately through
  resolveBitReference(), this patch adds getBit() for all Inits and
  resolves bit value by resolving plus getting the specified bit. This
  unifies the resolving of bit with other values and removes redundant
  logic for resolving bit only. In addition,
  BitsInit::resolveReferences() is optimized to take advantage of this
  origanization by resolving VarBitInit's variable reference first and
  then getting bits from it.

- The type interference in '!if' operator is revised to support possible
  combinations of int and bits/bit in MHS and RHS.

- As there may be illegal assignments from integer value to bit, says
  assign 2 to a bit, but we only check this during instantiation in some
  cases, e.g.

  bit V = !if(!eq(x, 17), 0, 2);

  Verbose diagnostic message is generated when invalid value is
  resolveed to help locating the error.

- PR8330 is fixed as well.
