Subject: [PATCH] RISC-V: Fix bug of TARGET_COMPUTE_MULTILIB implemented in riscv.
Date: Thu,  2 Feb 2023 19:46:04 +0800	[thread overview]
Message-ID: <20230202114604.2059-1-jinma@linux.alibaba.com> (raw)

MAX_MATCH_SCORE is not assigned anywhere except initialized to 0,
causing BEST_MATCH_MULTI_LIB to always be 0 or -1, which will
cause the result of TARGET_COMPUTE_MULTILIB hook to fail.
