simh debug integration is only done during simh builds, the original QEMU debug functionality is preserved. The slirp debug flags can be set by the environment variable SLIRP_DEBUG. Mask values 1 - CALL, 2 - MISC, 3 - ERROR.
This should work on all byte addressable host systems using GCC/clang to build.
The QEMU slirp code has been pried out of QEMU and stubs have been created to solve where the current slirp is entangled with the QEMU code. Ths slirp/simh directory contains all the necessary include and glue files to make this useful. Everything in the slirp directory is unmodified QEMU code.
