invoke.texi (RS/6000 and PowerPC Options): Document -mfloat-gprs.

Browse Source 
2003-04-07  Aldy Hernandez  <aldyh@redhat.com>

        * doc/invoke.texi (RS/6000 and PowerPC Options): Document
        -mfloat-gprs.

        * config/rs6000/rs6000.c: Delete rs6000_fprs.
        Declare rs6000_float_gprs.
        Declare rs6000_float_gprs_string.
        (rs6000_parse_float_gprs_option): New.
        (rs6000_override_options): Genericize rs6000_parse_* calls to use
        rs6000_parse_yes_no_option.
        Change check for cpu=8540, to use TARGET_E500.
        (rs6000_parse_isel_option): Delete.
        (rs6000_parse_spe_option): Delete.
        (rs6000_parse_vrsave_option): Delete.

        * config/rs6000/rs6000.h: Rename rs6000_fprs to rs6000_float_gprs.
        Define rs6000_float_gprs_string.
        (TARGET_OPTIONS): Add rs6000_float_gprs option.

        * config/rs6000/eabi.h (TARGET_FPRS): Change to use rs6000_float_gprs.

        * config/rs6000/eabispe.h: Set rs6000_float_gprs.
