Many m68k libm functions use their own system to share code between different types and functions, involving defining macros before including code for another function (for example, s_atan.c also acts as a template that can define other functions). Thes files serving as templates generate function aliases directly with e.g. "weak_alias (__CONCATX(__,FUNC), FUNC)" in s_atan.c. To be prepared to generate _Float32, _Float64 and _Float32x function aliases, this needs changing so that the libm_alias_* macros get used instead. As the macro to use varies depending on the type, that would mean additional macros to define in several different places to get the appropriate alias-generation macro used in each case. Rather than adding to the m68k-specific mechanisms, this patch converts the functions in question to use something closer to the math/ type-generic template mechanism. After this patch, these functions have m68k-specific templates such as s_atan_template.c, but those templates use all the same macros as in the math/ templates, such as FLOAT, M_DECL_FUNC, M_SUF and declare_mgen_alias. There is no automatic generation of the files such as s_atan.c that include the appropriate math-type-macros-*.h header and the template file (the existing automatic generation logic is only applicable for the fixed set of templates listed in math/ - and sysdeps sources always override files generated that way), so those files are still checked in, but they are all the obvious two-line files (with one additional definition in the case of the expm1 implementations), rather than making e.g. s_atan.c special. Functions are only converted where they should have aliases for _FloatN / _FloatNx types. Those m68k functions that do not generate public names (those that only generate __ieee754_*, with wrappers generating the public names, and classification functions that only exist once per format not once per type so don't get aliases) are unchanged. However, log1p (public names generated by wrapper) and significand (not provided for new types so no new aliases needed) needed changing because they previously included the atan implementations. Now, s_significand.c is the main implementation for functions with that prototype and using the old implementation approach, while log1p includes it in place of atan. Any further cleanups in this area (which preserve the proper set of functions getting aliases defined by libm_alias_float and libm_alias_double) are of course welcome, just not needed for the goals of this patch. Tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/m68k/m680x0/fpu/s_atan_template.c: New file. * sysdeps/m68k/m680x0/fpu/s_ceil_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_cos_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_expm1_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_fabs_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_floor_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_frexp_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_lrint_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_modf_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_nearbyint_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_remquo_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_rint_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_sin_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_sincos_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_tan_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_tanh_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_trunc_template.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_atan.c: Reimplement to use s_atan_template.c. * sysdeps/m68k/m680x0/fpu/s_atanf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_atanl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_ceil.c: Reimplement to use s_ceil_template.c. * sysdeps/m68k/m680x0/fpu/s_ceilf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_ceill.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_cos.c: Reimplement to use s_cos_template.c. * sysdeps/m68k/m680x0/fpu/s_cosf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_cosl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_expm1.c: Reimplement to use s_expm1_template.c. * sysdeps/m68k/m680x0/fpu/s_expm1f.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_expm1l.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_fabs.c: Reimplement to use s_fabs_template.c. * sysdeps/m68k/m680x0/fpu/s_fabsf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_fabsl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_floor.c: Reimplement to use s_floor_template.c. * sysdeps/m68k/m680x0/fpu/s_floorf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_floorl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_frexp.c: Reimplement to use s_frexp_template.c. * sysdeps/m68k/m680x0/fpu/s_frexpf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_lrint.c: Reimplement to use s_lrint_template.c. * sysdeps/m68k/m680x0/fpu/s_lrintf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_lrintl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_modf.c: Reimplement to use s_modf_template.c. * sysdeps/m68k/m680x0/fpu/s_modff.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_modfl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_nearbyint.c: Reimplement to use s_nearbyint_template.c. * sysdeps/m68k/m680x0/fpu/s_nearbyintf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_nearbyintl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_remquo.c: Reimplement to use s_remquo_template.c. * sysdeps/m68k/m680x0/fpu/s_remquof.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_remquol.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_rint.c: Reimplement to use s_rint_template.c. * sysdeps/m68k/m680x0/fpu/s_rintf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_rintl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_sin.c: Reimplement to use s_sin_template.c. * sysdeps/m68k/m680x0/fpu/s_sinf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_sinl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_sincos.c: Reimplement to use s_sincos_template.c. * sysdeps/m68k/m680x0/fpu/s_sincosf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_sincosl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_tan.c: Reimplement to use s_tan_template.c. * sysdeps/m68k/m680x0/fpu/s_tanf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_tanl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_tanh.c: Reimplement to use s_tanh_template.c. * sysdeps/m68k/m680x0/fpu/s_tanhf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_tanhl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_trunc.c: Reimplement to use s_trunc_template.c. * sysdeps/m68k/m680x0/fpu/s_truncf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_truncl.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_significand.c: Reimplement based on s_atan.c instead of including s_atan.c. * sysdeps/m68k/m680x0/fpu/s_significandf.c: Reimplement based on s_atanf.c instead of including s_atanf.c. * sysdeps/m68k/m680x0/fpu/s_significandl.c: Reimplement based on s_atanl.c instead of including s_atanl.c. * sysdeps/m68k/m680x0/fpu/s_log1p.c: Include s_significand.c instead of s_atan.c. * sysdeps/m68k/m680x0/fpu/s_log1pf.c: Include s_significandf.c instead of s_atanf.c. * sysdeps/m68k/m680x0/fpu/s_log1pl.c: Include s_significandl.c instead of s_atanl.c.
