Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|REOPENED |RESOLVED Resolution|--- |INVALID --- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> --- GCC uses GMP, MPFR (which uses GMP internally) and MPC (which uses MPFR). so yes it depends on GMP ABI being stable. Again if you are messing with the GMP ABI, you really should be doing a cross compiler to do a bootstrap of the compiler. THERE is nothing that can be done as you are changing the GMP ABI/API.
