At <http://gcc.gnu.org/wiki/Top-Level_Libgcc_Migration> I listed this
macro, and lots of others, under "used by the compiler itself and libgcc
(probably predefine macros if -fbuilding-libgcc in most cases, unless
predefined macros considered more generally useful)". I think that
approach still makes sense for improving the host / target tm.h
separation: use these tm.h macros directly only in the compiler, and make
the compiler, if -fbuilding-libgcc, predefine a macro for use in GCC's own
libraries.
So far only TRAMPOLINE_SIZE is handled like that; conversions of other
macros are welcome. The list on that wiki page may be a bit out of date,
but should still be a good starting point for this project.
