[libre-riscv-dev] Testing the simulator with qemu-5.0.0-rc0 and GDB

[Tobias Platen]

I've upgraded my installed version of QEMU to the latest version because my old version (included in Debian Buster) does not support "-machine powernv9".

When running launch.sh I get these warnings:
qemu-system-ppc64: warning: TCG doesn't support requested feature, cap-cfpc=workaround
qemu-system-ppc64: warning: TCG doesn't support requested feature, cap-sbbc=workaround
qemu-system-ppc64: warning: TCG doesn't support requested feature, cap-ibs=workaround
qemu-system-ppc64: warning: TCG doesn't support requested feature, cap-ccf-assist=on

When I run "powerpc64-linux-gnu-gdb -x gdbscript", I get the following error message:
