Subject: 	* arm-tdep.c (arm_push_arguments): Eliminate special float type
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6b230f1b26437c6a503302392ee57477b4c468ad;p=binutils-gdb.git

	* arm-tdep.c (arm_push_arguments): Eliminate special float type
	handling.
	* config/arm/tm-arm.h (COERCE_FLOAT_TO_DOUBLE): Define to call
	standard_coerce_float_to_double().
