* soft-fp: Add __extendhfsf2/__extendhfdf2, __truncsfhf2/__truncdfhf2, ↵liuhongt2021-07-071-0/+2
| | | | | | | | | | | | | | __eqhf2/__nehf2 1. Add __extendhfdf2/__extendhfsf2 to return an IEEE half converted to IEEE double/single. 2. Add __truncdfhf2/__extendsfhf2 to truncate IEEE double/single into IEEE half. 3. Add __eqhf2/__nehf2 to return 0 if a == b and a,b are not NAN, otherwise return 1. These are needed by x86 _Float16: https://software.intel.com/content/www/us/en/develop/download/intel-avx512-fp16-architecture-specification.html support in GCC.

* Do not use packed structures in soft-fp.Joseph Myers2018-02-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Building for soft-float ColdFire produces an error in soft-fp: In file included from ../sysdeps/ieee754/soft-fp/s_fmaf.c:42: ../soft-fp/single.h:85:3: error: 'packed' attribute ignored for field of type 'struct <anonymous>' [-Werror=attributes] } bits __attribute__ ((packed)); ^ While this error only appears in that particular case, this attribute is in fact never useful, on any architecture. If you have struct __attribute__ ((packed)) { ... } bits; or struct { ... } __attribute__ ((packed)) bits; then the attribute affects the layout of the structure type. But with the form used in this code struct { ... } bits __attribute__ ((packed)); the field bits is being declared packed, but the layout of its type has already been determined at that point. If on any platform the layout of the sequence of bit-fields were wrong without the use of a packed attribute, the attribute would need to be used via a definition of _FP_STRUCT_LAYOUT, not in its present position. So this patch removes the useless attribute to fix the build for ColdFire soft-float. Tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * soft-fp/double.h (union _FP_UNION_D): Do not use attribute packed on bits. * soft-fp/extended.h (union _FP_UNION_E): Likewise. * soft-fp/half.h (union _FP_UNION_H): Likewise. * soft-fp/quad.h (union _FP_UNION_Q): Likewise. * soft-fp/single.h (union _FP_UNION_S): Likewise.

* [soft-fp] Add support for various half-precision conversion routines.James Greenhalgh2016-09-211-0/+170
This patch adds conversion routines required for _Float16 support in AArch64. These are one-step conversions to and from TImode and TFmode. We need these on AArch64 regardless of presence of the ARMv8.2-A 16-bit floating-point extensions. In the patch, soft-fp/half.h is derived from soft-fp/single.h . The conversion routines are derivatives of their respective SFmode variants. * soft-fp/extendhftf2.c: New. * soft-fp/fixhfti.c: Likewise. * soft-fp/fixunshfti.c: Likewise. * soft-fp/floattihf.c: Likewise. * soft-fp/floatuntihf.c: Likewise. * soft-fp/half.h: Likewise. * soft-fp/trunctfhf2.c: Likewise.
