Jakob Stoklund Olesen fcad79671f Compute secondary sub-registers.
The sub-registers explicitly listed in SubRegs in the .td files form a
tree. In a complicated register bank, it is possible to have
sub-register relationships across sub-trees. For example, the ARM NEON
double vector Q0_Q1 is a tree:

  Q0_Q1 = [Q0, Q1],  Q0 = [D0, D1], Q1 = [D2, D3]

But we also define the DPair register D1_D2 = [D1, D2] which is fully
contained in Q0_Q1.

This patch teaches TableGen to find such sub-register relationships, and
assign sub-register indices to them. In the example, TableGen will
create a dsub_1_dsub_2 sub-register index, and add D1_D2 as a
sub-register of Q0_Q1.

This will eventually enable the coalescer to handle copies of skewed
sub-registers.

PerfectShuffle In r131488 I misunderstood how VREV works. It splits the vector in half and splits each half. Therefore, the real problem was that we were using a VREV64 for a 4xi16, when we should have been using a VREV32. 2011-05-18 06:42:21 +00:00
