Subject: [PATCH v1 3/6] RISC-V: Remove the unimplemented ISA extensions
Date: Fri,  1 Apr 2022 22:00:38 -0700	[thread overview]
Message-ID: <20220402050041.21302-4-palmer@rivosinc.com> (raw)
In-Reply-To: <20220402050041.21302-1-palmer@rivosinc.com>

This made sense when we die()d on unknown ISA extensions, but now that
we're just warning it's actually a bit detrimental: users won't see that
their unimplemented ISA extensions are silently having the wrong
definitions set, which may cause hard to debug failures.
