Subject: [gcc(refs/vendors/riscv/heads/gcc-13-with-riscv-opts)] RISC-V: Support FP llrint auto vectorization
Date: Thu, 12 Oct 2023 22:01:27 +0000 (GMT) [thread overview]
Message-ID: <20231012220127.5C2C5385696F@sourceware.org> (raw)
https://gcc.gnu.org/g:ca6043dc017b2c061a41a546b16216fbe0772516
commit ca6043dc017b2c061a41a546b16216fbe0772516
Author: Pan Li <pan2.li@intel.com>
Date: Thu Oct 12 11:20:36 2023 +0800
RISC-V: Support FP llrint auto vectorization
This patch would like to support the FP llrint auto vectorization.
* long long llrint (double)
This will be the CVT from DF => DI from the standard name's perpsective,
which has been covered in previous PATCH(es). Thus, this patch only add
some test cases.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/autovec/unop/test-math.h: Add type int64_t.
* gcc.target/riscv/rvv/autovec/unop/math-llrint-0.c: New test.
* gcc.target/riscv/rvv/autovec/unop/math-llrint-run-0.c: New test.
* gcc.target/riscv/rvv/autovec/vls/math-llrint-0.c: New test.
