* tcg/s390x: Fix tcg_out_dup_vec vs general registersRichard Henderson2022-03-141-0/+1
| | | | | | | | | | | | We copied the data from the general register input to the vector register output, but have not yet replicated it. We intended to fall through into the vector-vector case, but failed to redirect the input register. This is caught by an assertion failure in tcg_out_insn_VRIc, which diagnosed the incorrect register class. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
* tcg/s390x: Fix INDEX_op_bitsel_vec vs VSELRichard Henderson2022-03-141-1/+1
| | | | | | | | | | The operands are output in the wrong order: the tcg selector argument is first, whereas the s390x selector argument is last.

* tcg/s390x: Fix tcg_out_dupi_vec vs VGMRichard Henderson2022-03-141-2/+2
| | | | | | | The immediate operands to VGM were in the wrong order, producing an inverse mask. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

| | | | | | | | | | We've had placeholders for these opcodes for a while, and should have support on ppc, s390x and avx512 hosts.

| | | | | | | | | | | | | | Renaming defines for quad in their various forms so that their signedness is now explicit. Done using git grep as suggested by Philippe, with a bit of hand edition to keep assignments aligned.
