Subject: [PULL 20/37] target/riscv: additional macros to check instruction support
Date: Sat,  8 Jan 2022 15:50:31 +1000	[thread overview]
Message-ID: <20220108055048.3512645-21-alistair.francis@opensource.wdc.com> (raw)
In-Reply-To: <20220108055048.3512645-1-alistair.francis@opensource.wdc.com>

From: Frédéric Pétrot <frederic.petrot@univ-grenoble-alpes.fr>

Given that the 128-bit version of the riscv spec adds new instructions, and
that some instructions that were previously only available in 64-bit mode
are now available for both 64-bit and 128-bit, we added new macros to check
for the processor mode during translation.
Although RV128 is a superset of RV64, we keep for now the RV64 only tests
for extensions other than RVI and RVM.
