Looking at the patch, you've changed FIRST_PSEUDO_REGISTER (internal gcc
thing, so fine), but that also changed DWARF_FRAME_REGISTER which was
computed based on FIRST_PSEUDO_REGISTER. Isn't that an ABI break in the
unwinder (think about having parts of unwinder linked from different
versions of libgcc)?
Can't we just tweak DWARF_FRAME_REGISTER not to include those registers?
