Subject: [PATCH 2/6] target/riscv: Check for async flag in case of RISCV_EXCP_SEMIHOST.
Date: Thu, 18 May 2023 12:38:34 +0100	[thread overview]
Message-ID: <20230518113838.130084-3-rkanwal@rivosinc.com> (raw)
In-Reply-To: <20230518113838.130084-1-rkanwal@rivosinc.com>

RISCV_EXCP_SEMIHOST is set to 0x10, which can also be a local
interrupt as well. This change adds a check for async flag
before invoking semihosting logic.
