Subject: [PATCH v2 2/2] RISC-V: Add testcase for 6 byte instruction
Date: Tue, 18 Feb 2025 19:35:22 -0800 [thread overview]
Message-ID: <20250218-fix_gas_abort-v2-2-14457aa7387e@rivosinc.com> (raw)
In-Reply-To: <20250218-fix_gas_abort-v2-0-14457aa7387e@rivosinc.com>
6-byte instructions were causing gas to abort. Add a test to ensure this
is avoided in the future.
