Subject: [PATCH 1/5] [RISC-V] Recognize Zicond extension
Date: Wed, 19 Jul 2023 18:11:52 +0800 [thread overview]
Message-ID: <20230719101156.21771-2-zengxiao@eswincomputing.com> (raw)
In-Reply-To: <20230719101156.21771-1-zengxiao@eswincomputing.com>
This patch is the minimal support for Zicond extension, include
the extension name, mask and target defination.
gcc/ChangeLog:
* common/config/riscv/riscv-common.cc: New extension.
* config/riscv/riscv-opts.h (MASK_ZICOND): New mask.
(TARGET_ZICOND): New target.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/attribute-20.c: New test.
* gcc.target/riscv/attribute-21.c: New test.
