From 7e9be673cb1b0be0f4279a960c2ecb28a147c327 Mon Sep 17 00:00:00 2001 From: zhouchuangao Date: Sat, 24 Apr 2021 08:59:50 -0700 Subject: MIPS: BCM63XX: Use BUG_ON instead of condition followed by BUG. BUG_ON uses unlikely in if(), it can be optimized at compile time. Usually, the condition in if() is not satisfied. In my opinion, this can improve the efficiency of the multi-stage pipeline.
