PPC32 support,about monooni/binarydist

Comments (3)

kadler commented on June 20, 2024

I'm not saying you can't or shouldn't do it, but it seems odd to add 32-bit PPC support when a lot of others are dropping it: Java, Node.js, Linux Distros, IBM i rpms, ...

from binarydist.

Updated diff; this time the ctor is jumping off in no man's land, but somewhere around JIT emitted code...
