an in-tree mpfr build enables inline asm code, which makes the mips-bootstrap fail, because at least mpfr 2.4.2 uses the "=h" constraint but in config/mips/constraints.md we find: "Formerly the @code{hi} register. This constraint is no longer supported.".Using asm code is generally not desirable for in-tree mpfr builds.
Why not?
So I looked for a way to disable the asm code, and found it can be done, but differently than for in-tree gmp. See the attached patch.
Fix mpfr instead not to use that constraint? Bernd
