[mips] Added support for various EVA ASE instructions.

[s.egerton]

Summary

Added support for the following instructions:

CACHEE, LBE, LBUE, LHE, LHUE, LWE, LLE, LWLE, LWRE, PREFE,
SBE, SHE, SWE, SCE, SWLE, SWRE, TLBINV, TLBINVF

This required adding some infrastructure for the EVA ASE.

There's few comments here but it's all fairly minor things.

lib/Target/Mips/MipsEVAInstrFormats.td

16–19

This belongs with the other INSN_* classes in MipsInstrInfo.td

23

Spelling nit: I'm trying to keep the names of new format classes related to their names in the documentation (<major-opcode-name>_<arbitrary>_FM).

Could you call this: SPECIAL3_EVA_LOAD_STORE_FM or similar?

37–52

This is the same as LWE_FM above. Could you use that instead?

lib/Target/Mips/MipsEVAInstrInfo.td

19

Could you follow the conventions from Mips{DSP,MSA,32r6,64r6}InstrInfo.td? These conventions define concrete encodings in *_ENC classes, operation descriptions in *_DESC classes and apply predicates in the final def.

This request is mostly spelling nits and syntax but there is also a change to the inheritance hierarchy. This change is that the format inherits from MipsInst (possibly via another class, see MipsR6Inst) instead of the operation description inheriting from it.

test/MC/Mips/eva/valid-xfail.s

1

The xfail status and filename of this are misleading. It's correct that EVA instructions fail to assemble when EVA is not enabled so it shouldn't be an xfail. I think you want a invalid-noeva.s with similar contents that checks the error message produced by each instruction. See invalid-mips1.s for an example.

test/MC/Mips/eva/valid_R6-xfail.s

1

These aren't valid for 32r6/64r6. [ls]w[lr] and the EVA equivalents [ls]w[lr]e were removed in 32r6/64r6. I think you want an invalid-*.s to cover them

[s.egerton]

Responded to reviewers comments.

[dsanders]

LGTM with a minor change to the predicates.

lib/Target/Mips/MipsEVAInstrInfo.td

176–182

HasEVA doesn't belong in AdditionalPredicates. Define a INSN_EVA_NOT_32R6_64R6 and use that instead of ISA_MIPS1_NOT_32R6_64R6.

Also, drop the assignment to EncodingPredicates. There was a FIXME on the LWL/LWR/SWL/SWR indicating that it was probably a bug.

185

Likewise, drop this EncodingPredicates too.

[s.egerton]

Responded to reviewers comments. Also, changed 'mem' in operands to 'mem_simm9' in order to properly detect the upper bounds for these operands.
