Subject: fix bug in CSR set SVVL: val has already been looked up
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=88a882c1e325d1a824dacabac536ead772d52b55;p=riscv-isa-sim.git

fix bug in CSR set SVVL: val has already been looked up

csrrw.h has been modified to invert the order of set/get, so the
call to processor_t::set_csr(SVVL, val) will do the right thing
and the subsequent (delayed) call to get_csr will return the
state.vl value in the chosen RD

all good
