commit r16-2277-g430be3b933bfac1f1caace4f0ef393a4d434ea0f
Author: Pan Li <pan2...@intel.com>

RISC-V: Support RVVDImode for avg3_floor auto vect
The avg3_floor pattern leverage the add and shift rtl
with the DOUBLE_TRUNC mode iterator. Aka, RVVDImode
iterator will generate avg3rvvsimode_floor, only the
element size QI, HI and SI are allowed.
Thus, this patch would like to support the DImode by
the standard name, with the iterator V_VLSI_D.
The below test suites are passed for this patch series.
* The rv64gcv fully regression test.
gcc/ChangeLog:
* config/riscv/autovec.md (avg<mode>3_floor): Add new
pattern of avg3_floor for rvv DImode.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/autovec/avg.h: Add int128 type when
xlen == 64.
* gcc.target/riscv/rvv/autovec/avg_ceil-run-1-i16-from-i32.c:
Suppress __int128 warning for run test.
* gcc.target/riscv/rvv/autovec/avg_ceil-run-1-i16-from-i64.c: Ditto.
* gcc.target/riscv/rvv/autovec/avg_ceil-run-1-i32-from-i64.c: Ditto.
* gcc.target/riscv/rvv/autovec/avg_ceil-run-1-i8-from-i16.c: Ditto.
* gcc.target/riscv/rvv/autovec/avg_ceil-run-1-i8-from-i32.c: Ditto.
* gcc.target/riscv/rvv/autovec/avg_ceil-run-1-i8-from-i64.c: Ditto.
* gcc.target/riscv/rvv/autovec/avg_data.h: Fix one incorrect
test data.
* gcc.target/riscv/rvv/autovec/avg_floor-run-1-i16-from-i32.c:
Ditto.
* gcc.target/riscv/rvv/autovec/avg_floor-run-1-i16-from-i64.c:
Ditto.

* gcc.target/riscv/rvv/autovec/avg_floor-run-1-i8-from-i64.c: Ditto.
* gcc.target/riscv/rvv/autovec/avg_floor-1-i64-from-i128.c: New
test.
* gcc.target/riscv/rvv/autovec/avg_floor-run-1-i64-from-i128.c: New
test.
