From 20fbc07af1ebd5a68b8fd1203ceb4cab60bd7328 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?R=C3=A9mi=20Denis-Courmont?= Date: Sat, 11 May 2024 19:05:06 +0300 Subject: [PATCH] lavu/riscv: remove bogus B extension The B Bit manipulation extension was not defined to this day, and probably never will. Instead it was broken down into Zba, Zbb, Zbc and Zbs with no particular blessed set to make up B. This removes the bogus field test. Linux never set this bit, nor (AFAICT) did FreeBSD or any other OS. We can always add it back in the unlikely event that it gets taken into use. --- libavutil/riscv/cpu.c | 2 -- 1 file changed, 2 deletions(-) diff --git a/libavutil/riscv/cpu.c b/libavutil/riscv/cpu.c index 1fe1a397c4..9b57d77502 100644 --- a/libavutil/riscv/cpu.c +++ b/libavutil/riscv/cpu.c @@ -91,8 +91,6 @@ int ff_get_cpu_flags_riscv(void) ret |= AV_CPU_FLAG_RVF; if (hwcap & HWCAP_RV('D')) ret |= AV_CPU_FLAG_RVD; - if (hwcap & HWCAP_RV('B')) - ret |= AV_CPU_FLAG_RVB_ADDR | AV_CPU_FLAG_RVB_BASIC; /* The V extension implies all Zve* functional subsets */ if (hwcap & HWCAP_RV('V'))
