Subject: [gcc r14-4610] RISC-V: Add test for FP llround auto vectorization
Date: Fri, 13 Oct 2023 06:21:45 +0000 (GMT) [thread overview]
Message-ID: <20231013062145.2FE633858D1E@sourceware.org> (raw)
https://gcc.gnu.org/g:6b580560a0e393e3b65567263e2cf5477d670592
commit r14-4610-g6b580560a0e393e3b65567263e2cf5477d670592

RISC-V: Add test for FP llround auto vectorization
The below FP API are supported already by sharing the same standard
name, as well as the machine mode.
long long llround (double);
This patch would like to add the test cases for ensuring the correctness.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/autovec/unop/math-llround-0.c: New test.
* gcc.target/riscv/rvv/autovec/unop/math-llround-run-0.c: New test.
* gcc.target/riscv/rvv/autovec/vls/math-llround-0.c: New test.
