From: Luis Pires <luis.pires@eldorado.org.br>
New macros that add FLAGS and FLAGS2 checking were added for
both TRANS and TRANS64.
Signed-off-by: Luis Pires <luis.pires@eldorado.org.br>
[ferst: - TRANS_FLAGS2 instead of TRANS_FLAGS_E
- Use the new macros in load/store vector insns ]

Moved the instructions vmulesb, vmulosb, vmuleub, vmuloub,
vmulesh, vmulosh, vmuleuh, vmulouh, vmulesw, vmulosw,
muleuw and vmulouw from legacy to decodetree. Implemented
the instructions vmulesd, vmulosd, vmuleud, vmuloud.

I don't think that you should decompose 4 high-part 32-bit multiplies into 4 32-bit
multiplies plus lots of arithmetic. This is not a win. You're actually better off with
pure integer arithmetic here.
You could instead widen these into 2 64-bit multiplies, plus some arithmetic. That's
certainly closer to the break-even point.

As for the two high-part 64-bit multiplies, I think that should definitely remain an
integer operation.
You probably want to expand these with inline integer operations using .fni[48].

Very much likewise.

The move into tmp1 is dead here.
I think you wanted a third add2 here, adding the old tmp0 + new rc word.

It would be better to collect this into a single composite gvec operation (x86 is
especially bad with unsupported vector operation sizes).
Use GVecGen3, provide the relevant .fni4/.fni8/.fniv functions and the vecop_list. We
have elsewhere relied on 4 integer operations being expanded, when the vector op itself
isn't supported, so you should be able to drop the .fnio out-of-line helper.

I don't understand the ctpop here. I would have expected:
tcg_gen_and_i64(set, t0, t1);
tcg_gen_or_i64(clr, t0, t1);
tcg_gen_setcondi_i64(TCG_COND_EQ, set, set, -1); /* all bits set */
tcg_gen_setcondi_i64(TCG_COND_EQ, clr, clr, 0); /* all bits clear */

Vector compare already produces -1; no need for anything beyond the cmp.

No shifting required, only the cmp.

Therefore no vecop_list required (cmp itself is mandatory).

Without vecop_list, we hit the assert in tcg_assert_listed_vecop, which
is called from tcg_gen_cmp_vec. Am I missing something?

It would be much better to not use a branch.
E.g.
get_avr64(t0, a->vra, true);
get_avr64(t1, a->vrb, true);
tcg_gen_xor_i64(c0, t0, t1);
get_avr64(t0, a->vra, false);
get_avr64(t1, a->vrb, false);
tcg_gen_xor_i64(c1, t0, t1);
tcg_gen_or_i64(c0, c0, c1);
tcg_gen_setcondi_i64(TCG_COND_EQ, c0, c0, 0);
tcg_gen_neg_i64(c0, c0);
set_avr64(a->vrt, c0, true);
set_avr64(a->vrt, c0, false);
tcg_gen_extrl_i64_i32(crf, c0);
tcg_gen_andi_i32(crf, crf, 0xa);
tcg_gen_xori_i32(crf, crf, 0x2);

The only reason you're passing in env is for crf[6], which requires you to pass in a
second argument. And you're not using the return value.
It would be better to always return the rc value, and only conditionally assign it.
E.g.
if (a->rc) {
gen_helper(cpu_crf[6], vrt, vrb);
} else {
TCGv_i32 discard = tcg_temp_new_i32();
gen_helper(discard, vrt, vrb);
tcg_temp_free_i32(discard);
}

There's a bit of redundancy here, and if we exploit that we can remove the branches.
Compute the mask modulo 8. That result applies to either the first or second word, or
neither. Use 3 movcond to select among the cases:
sh = (rb & 7) << 3;
mask = ~(-1 << sh);
ml = rb < 8 ? mask : 0;
mh = rb < 8 ? 0 : mask;
mh = rb < 16 ? mh : -1;
lo &= ml;
hi &= mh;

This is going to produce up to 3*64 operations (n=2).
You can produce more than one output pairing per shift,
and produce the same result in 3*lg2(64) operations.
I've given an example like this on the list before, recently.
I think it was in the context of some riscv bit manipulation.

and similarly for larger N. For N >= 4, I believe that half of the masking may be elided,
because there are already zeros in which to place bits.

It's probably worth working through the various N to make sure you know which masking is
required.

xscmpnedp was added in ISA v3.0 but removed in v3.0B. This patch
removes this instruction as it was not in the final version of v3.0.
