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.
selectImpl is able to select G_FABS when we set bank for vector
operands to fprb. Add detailed tests.
Note: G_FABS is generated from llvm-ir intrinsics llvm.fabs.*,
and at the moment MIPS is not able to generate this intrinsic for
vector type (some targets generate vector llvm.fabs.* from calls
to a builtin function).
We can handle fabs using __builtin_msa_fmax_a_<format> and passing
same vector as both arguments. __builtin_msa_fmax_a_<format> will
be directly selected into FMAX_A_<format> in legalizeIntrinsic.
