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.
