Your original point came across as a complaint that GCC does not
support plugins because of some FSF policy, despite GCC supporting
plugins because of the Runtime Exception that I championed.

GCC is working toward re-factoring its code base toward a more
compositional approach for "toolification". One can look at
presentations from the recent GNU Cauldron 2013 for discussion of the

Clang/LLVM has technical advantages and GCC has technical advantages.

Your comments presume that the choice is because of technical merit or
philosophy impeding technical development. The issue for companies is
control: which compiler allows them better access / control over the
toolchain control point of the ecosystem and which allows them to
create a walled garden to improve their margins and their business

that support the business decision, it makes it easier for the company
