Issue when installing PK for RV32E #331

Open koni-ey opened 3 weeks ago

koni-ey commented 3 weeks ago

I want to set up a simulation environment for a RV32EMFC architecture. (Spike apperently supports RV32E so i assumed PK does too).

Toolchain seems to be correctly installed as riscv32-unknown-elf-gcc -Q --help=target reports: 

-mabi = ilp32e
-march = rv32emfc_ziscr

I now tried to compile pk with ../configure --prefix=$RISCV --host=riscv32-unknown-elf --with-arch=rv32emfc_zicsr --with-abi=ilp32e unfortunately I get the following output:

It seems like its trying to acces registers > x15 which is weird with RV32E arch and abi specified.

Did someone succeed building it for RV32E or set up a simulation environment for it?
