Perhaps I'm missing something, but wouldn't that mean that the
assembler functions would no longer be inline?
What I am suggesting here is that we use assembly routines instead
of asms to implement libgcc1. This only affects compilation of libgcc1.a.
It does not affect any user programs, as libgcc1 source code is never used for
anything but libgcc1.a.
libgcc1 routines can be expanded inline, but this is done by either by machine
independent code in the middle-end, or machine dependent patterns in the md
file. The libgcc1 source code has nothing to do with this.
