Jakob Stoklund Olesen [Tue, 4 Oct 2011 15:28:49 +0000 (15:28 +0000)]
Teach TableGen to infer missing register classes.

The set of register classes should be closed under sub-register
operations and intersections. That will allow the register allocator to
model combinations of constraints accurately.

This patch implements the easiest form of register class inference:  For
every register class, and for every sub-register SubIdx, the subset of
registers in RC that have a SubIdx sub-register should also be a register
class.

This does create some new register classes for the targets in the tree:

ARM gets a new QQQQPR_with_ssub_0.  This class was omitted from the .td
file on purpose because it only has two registers.  InstrEmitter and
RegisterCoalescer have safeguards against selecting too small register
classes, so it is harmless.

PowerPC gets a G8RC_with_sub_32 class because LR is not a sub_32
sub-register of LR8.  I think that might be an omission?

X86 puts RIP in the GR64 class, and since that register doesn't have
8-bit sub-registers, we get:

  GR64_with_sub_8bit
  GR64_TC_with_sub_8bit
  GR64_NOREX_with_sub_8bit
  GR64_TC_with_sub_8bit_hi

The various CodeGen classes have already been fixed so adding new
register classes should not affect compile time.

13 years agoStore sub-class lists as a bit vector.
Jakob Stoklund Olesen [Fri, 30 Sep 2011 22:19:07 +0000 (22:19 +0000)]
Store sub-class lists as a bit vector.

This uses less memory and it reduces the complexity of sub-class
operations:

- hasSubClassEq() and friends become O(1) instead of O(N).

- getCommonSubClass() becomes O(N) instead of O(N^2).

In the future, TableGen will infer register classes.  This makes it
cheap to add them.
