* tcg: Add INDEX_op_dupm_vecRichard Henderson2019-05-147-41/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow the backend to expand dup from memory directly, instead of forcing the value into a temp first. This is especially important if integer/vector register moves do not exist. Note that officially tcg_out_dupm_vec is allowed to fail. If it did, we could fix this up relatively easily: VECE == 32/64: Load the value into a vector register, then dup. Both of these must work. VECE == 8/16: If the value happens to be at an offset such that an aligned load would place the desired value in the least significant end of the register, go ahead and load w/garbage in high bits. Load the value w/INDEX_op_ld{8,16}_i32. Attempt a move directly to vector reg, which may fail. Store the value into the backing store for OTS. Load the value into the vector reg w/TCG_TYPE_I32, which must work. Duplicate from the vector reg into itself, which must work. All of which is well and good, except that all supported hosts can support dupm for all vece, so all of the failure paths would be dead code and untestable.

* tcg: Manually expand INDEX_op_dup_vecRichard Henderson2019-05-133-10/+118
| | | | | | | | | This case is similar to INDEX_op_mov_* in that we need to do different things depending on the current location of the source. Signed-off-by: Richard Henderson <richard.henderson@linaro.org> --- v3: Added some commentary to the tcg_reg_alloc_* functions.
* tcg: Promote tcg_out_{dup,dupi}_vec to backend interfaceRichard Henderson2019-05-133-3/+26
| | | | | | | | | | | The i386 backend already has these functions, and the aarch64 backend could easily split out one. Nothing is done with these functions yet, but this will aid register allocation of INDEX_op_dup_vec in a later patch. Adjust the aarch64 tcg_out_dupi_vec signature to match the new interface.
