Subject: Defined illegal instruction
Date: Fri, 9 Feb 2024 18:03:40 +0100	[thread overview]
Message-ID: <4EF79A76-0C4A-492C-95E5-F12B338F637D@jacob.remcomp.fr> (raw)

The riscv processor defines an illegal instruction (all zeroes). I do not find the mnemonic used by gas for this. As far as I remember, the x86 also has a defined illegal instruction.

I find an instruction called « unimp » . It generates something else (an attempt to write into a read only special register). Is that the « defined illegal instruction » for risk?

Thanks for any answers

Jacob
