13 years agoCompute lists of sub-regs, super-regs, and overlapping regs.
Jakob Stoklund Olesen [Sun, 12 Jun 2011 03:05:52 +0000 (03:05 +0000)]
Compute lists of sub-regs, super-regs, and overlapping regs.

Besides moving structural computations to CodeGenRegisters.cpp, this
also well-defines the order of these lists:

- Sub-register lists come from a pre-order traversal of the graph
  defined by the SubRegs lists in the .td files.

- Super-register lists are topologically ordered so no register comes
  before any of its sub-registers. When the sub-register graph is not a
  tree, independent super-registers appear in numerical order.

- Lists of overlapping registers are ordered according to register
  number.

This reverses the order of the super-regs lists, but nobody was
depending on that. The previous order of the overlaps lists was odd, and
it may have depended on the precise behavior of std::stable_sort.

The old computations are still there, but will be removed shortly.

Remove custom allocation order boilerplate that is no longer needed.

The register allocators automatically filter out reserved registers and
place the callee saved registers last in the allocation order, so custom
methods are no longer necessary just for that.

Some targets still use custom allocation orders:

ARM/Thumb: The high registers are removed from GPR in thumb mode. The
NEON allocation orders prefer to use non-VFP2 registers first.

X86: The GR8 classes omit AH-DH in x86-64 mode to avoid REX trouble.

SystemZ: Some of the allocation orders are omitting R12 aliases without
explanation. I don't understand this target well enough to fix that. It
looks like all the boilerplate could be removed by reserving the right
registers.

Get allocation orders from RegisterClassInfo when possible.

Only target-dependent hints require callbacks. The RCI allocation order
has CSR aliases last according to their order of appearance in the
getCalleeSavedRegs list. This can depend on the calling convention.

This way, AllocationOrder::next doesn't have to check for reserved
registers, and CSRs are always allocated last, even with weird calling
conventions.

Don't try to be clever, just preserve the target's allocation order.

The order of registers returned by getCalleeSavedRegs is used to lay out
the fixed stack slots for CSRs. Some targets like their CSRs used from
one end, and some targets want them used from the other end.

When computing an allocation order, simply preserve the relative
ordering of CSRs that the target specifies in its allocation order.
Reordering CSRs would break some targets, ARM in particular.

We still place volatiles before the CSRs, providing slightly better
results with different calling conventions.
