This patch arranges for the glibc build to generate a header first-versions.h that defines macros for the earliest symbol version in which each public symbol (GLIBC_[0-9]* symbol version, name only uses C identifier characters) is available. This is used in sysdeps/ieee754/ldbl-opt/math-type-macros-double.h to replace the manually defined LDOUBLE_*_libm_version macros for various functions defined using type-generic templates, the purpose of which is to use in LONG_DOUBLE_COMPAT tests "was this function originally added before glibc supported long double != double on this platform?". As discussed in <https://sourceware.org/ml/libc-alpha/2016-12/msg00246.html>, I expect this to be useful more generally in reducing the amount of special-case code needed in ldbl-opt and ldbl-64-128. Tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by this patch. * scripts/versions.awk: Generate first-versions.h. * sysdeps/ieee754/ldbl-opt/math-type-macros-double.h: Include <first-versions.h>.

[!M_LIBM_NEED_COMPAT] (M_LIBM_NEED_COMPAT): Use FIRST_VERSION_libm_* macros. [!declare_mgen_libm_compat] (declare_mgen_libm_compat): Likewise. * Makerules [$(build-shared) = yes && !avoid-generated] (before-compile): Add $(common-objpfx)first-versions.h. [$(build-shared) = yes && !avoid-generated] ($(common-objpfx)first-versions.h): New target. ($(common-objpfx)sysd-versions): Depend on and change to rule for building $(common-objpfx)versions.stmp. |
