* sparc-nat.c (store_inferior_registers): Fill in all members of
inferior_fp_registers by reading them from the inferior before
modifying and writing them back.
Fixes unexplainable inferior FP exceptions after calls to the inferior
or setting of floating point registers.
* mips-tdep.c (mips_skip_prologue): Skip move of argument register
to register which is generated by gcc-2.4.
