I've not checked how plugins are implemented in gcc, but I'd assume it either passes something like a struct with function pointers for its "public interface", or it is linked with -rdynamic. > (Unless you don't strip the dynamic symbols linked with -rdynamic when > building cc1) This does not make any sense, striping debugging symbols should not affect either approach. Otherwise this is like suggesting shared libraries cannot be stripped because programs will not be able to link against them… Also if the backends are actually compiled with -rdynamic this should be giving better backtraces than otherwise, and might actually be enough for what is being sought out in here anyway.
