Indeed.
There are people working right now on improvements to modularity in GCC,
elimination of global state, and support for use of GCC in a JIT library,
led by Andrew MacLeod and David Malcolm. Contributions to those sorts of
efforts (and to the plugin interface) are more useful than rhetoric. No
policy objections are being made to these patches, it's simply a matter of
the work involved. If people want suggestions that don't conflict with
what Andrew and David are working on, a couple of suggestions:
* We have about 700 target macros (my script lists 697 right now, but
there are likely some false positives, and maybe false negatives), all of
which should move to the hooks mechanism to enable multiple targets to be
supported in a single compiler binary, and to get other benefits such as
not having the build of GCC fail with warnings seen only for some targets
because of differences in the target macro definitions. I expect a large
proportion of these (not used in #if or in code built for the target,
etc.) could be converted to hooks using some form of script-based
automatic refactoring, possibly with manual fine-tuning of the resulting
patches.
* Andrew MacLeod's plans for improving static typing are I think largely
about the middle end - there is plenty of scope for improving static
typing of datastructures used in the front ends, and cleanly separating
them from the language-independent compiler as far as possible.
