2004-09-07 David Daney <ddaney@avtrex.com>
* config.gcc: Added support for --with-divide=[breaks|traps] for
mips targets.
* config/mips/mips.h (MASK_DIVIDE_BREAKS): New target_flags bit.
(TARGET_DIVIDE_TRAPS): New macro.
(TARGET_SWITCHES): Added -mdivide-traps and -mdivide-breaks.
(OPTION_DEFAULT_SPECS): Added --with-divide= support.
* config/mips/mips.c (mips_idiv_insns): Generate proper count on
GENERATE_DIVIDE_TRAPS.
(mips_output_division): Emit conditional trap if
GENERATE_DIVIDE_TRAPS is set.
* doc/install.texi: Document --with-divide.
* doc/invoke.texi: Document -mdivide-traps and -mdivide-breaks.
