sideleg and sedeleg csrs are not part of riscv isa spec anymore, these csrs were part of N extension which is removed from the riscv isa specification. These commits removed all traces of these csrs from riscv spec (https://github.com/riscv/riscv-isa-manual) - commit f8d27f805b65 ("Remove or downgrade more references to N extension (#674)") commit b6cade07034d ("Remove N extension chapter for now") Signed-off-by: Rahul Pathak <rpathak@ventanamicro.com> Reviewed-by: Andrew Jones <ajones@ventanamicro.com> --- disas/riscv.c | 2 -- target/riscv/cpu_bits.h | 2 -- 2 files changed, 4 deletions(-)
