I would like having a global cpu_name_by_type_name() function. I wouldn't want to force each architecture to provide yet another string conversion/parsing function, though. >=20 > Should we define an automatically expanded TARGET_CPU_TYPE_SUFFIX? > Then we could have generic machine code to parse the names. I think we could do that, but with a CPUClass field instead of a preprocessor macro. For a reference on existing corner cases of CPU model name parsing that might get in the way, see this series: https://www.mail-archive.com/qemu-devel@nongnu.org/msg611813.html If you are interested, I have work in progress for a generic CPU model listing function at: https://github.com/ehabkost/qemu-hacks/commits/work/cpu-generic-list https://github.com/ehabkost/qemu-hacks/commit/df122e7e47476d7e2b7b809a4b4= 120537f50c137 --=20 Eduardo
