* config/i386/tm-i386aix.h (NUM_FPREGS, NUM_REGS, REGISTER_BYTES):
Override definitions to include the normal FPU registers.
(REGISTER_CONVERTIBLE, REGISTER_CONVERT_TO_VIRTUAL,
REGISTER_CONVERT_TO_RAW): Removed. The default definitions are
fine for AIX/i386.
(i387_to_double, double_to_i387): Remove prototypes.
2000-03-02 Kevin Buettner <kevinb@redhat.com>
* findvar.c (extract_floating, store_floating): Use target
