There are no 64-bit variants of these ALU / SETHI instructions in V9.
Remove these instruction definitions and add patterns to match DAG nodes
to the generic instructions defined in SparcInstrInfo.td.
This is not strictly NFC because of the changes in
`2011-01-11-FrameAddr.ll` test. The reason is that Sparc delay slot
filler pass handled ADDrr but not ADDXrr, which are now the same
instruction.
LEA_ADDri and LEAX_ADDri are printed / encoded the same way as ADDri. I
had to change the type of simm13Op so that it can be used in both 32-
and 64-bit modes. This required the changes in operands of some
InstAliases.
This will currently accept the old number of bytes syntax, and convert
it to a scalar. This should be removed in the near future (I think I
converted all of the tests already, but likely missed a few).
Not sure what the exact syntax and policy should be. We can continue
printing the number of bytes for non-generic instructions to avoid
test churn and only allow non-scalar types for generic instructions.
This will currently print the LLT in parentheses, but accept parsing
the existing integers and implicitly converting to scalar. The
parentheses are a bit ugly, but the parser logic seems unable to deal
without either parentheses or some keyword to indicate the start of a
type.
The generated code for the split fp128 load/stores was missing a small yet important adjustment to the pointer metadata being fed into `getStore` and `getLoad`, making it out of sync with the effective memory address.
This problem often resulted in instructions being scheduled in the wrong order.
I also took this chance to clean up some "wrong" uses of `getAlignment` as done in D77687.
Thanks @jrtc27 for finding the problem and providing a patch.
