Jakub Jelinek 37002cbcd2 * soft-fp/op-common.h (FP_TRUNC): Replace raising of FP_EX_INEXACT
with setting the sticky bit. 
* math/test-misc.c (main): Add more truncation tests.
	* soft-fp/floatunsidf.c (__floatunsidf): Use DFtype instead of
	double in the function declaration.
	* soft-fp/floatundidf.c (__floatundidf): Use DFtype instead of
	double in the function declaration.
	* soft-fp/floatunsisf.c (__floatunsisf): Use SFtype instead of
	float in the function declaration.
	* soft-fp/floatunsisf.c (__floatunsisf): Use SFtype instead of
	float in the function declaration.

	* soft-fp/extended.h (FP_UNPACK_RAW_E): Do not increase X##_e for
	denormal operands.  Do not generate FP_EX_DENORM exception.
	(FP_UNPACK_RAW_EP): Ditto.
	(FP_UNPACK_SEMIRAW_E): Use FP_UNPACK_RAW_E instead of
	undefined _FP_UNPACK_RAW_E.
	(FP_UNPACK_SEMIRAW_EP): Use FP_UNPACK_RAW_EP instead of
	undefined _FP_UNPACK_RAW_EP.
	(FP_PACK_SEMIRAW_E): Use FP_PACK_RAW_E instead of
	undefined _FP_PACK_RAW_E.
	(FP_PACK_SEMIRAW_EP): Use FP_PACK_RAW_EP instead of
	undefined _FP_PACK_RAW_EP.

	* op-2.h (_FP_FRAC_COPY_2_2): Define as alias to _FP_FRAC_COPY_2.
	* op-4.h (_FP_FRAC_COPY_2_2): Define as alias to _FP_FRAC_COPY_4.

	* soft-fp/op-common.h (FP_EXTEND): Do not abort when
	_FP_EXPBIAS_##dfs == _FP_EXPBIAS_##sfs.  Handle denormals for
	this case.
	* soft-fp/op-common.h (FP_TRUNC): Ditto.
	* soft-fp/op-common.h (FP_TRUNC): Replace raising of FP_EX_INEXACT
	with setting the sticky bit.
