* 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.
