This patch adds support for libm_alias_ldouble and libm_alias_float128 to create *f64x function aliases when appropriate. Making such aliases work for functions defined in assembly sources requires adding some semicolons after weak_alias calls in alias macro definitions. For C, semicolons are already present in the macros called when required, but a GNU C extension allows excess semicolons at file scope in a source file (and glibc already uses this), so it is OK to have extra semicolons present in the macro definitions. For assembly sources, making multiple alias macro calls from a single macro expansion means there are no newlines between the calls, so an explicit separator is needed. If hppa were to have .S sources in libm, a more complicated approach would be needed that used ASM_LINE_SEP when building assembly sources but not for C, but right now there are no such sources so just using a semicolon (as already present unconditionally in some such macro expansions) suffices. Tested for x86_64, including in conjunction with _Float64x support patches. * sysdeps/generic/libm-alias-float128.h: Include <bits/floatn.h>. (libm_alias_float128_other_r): If [__HAVE_FLOAT64X && !__HAVE_FLOAT64X_LONG_DOUBLE], define f64x alias. (libm_alias_float128_r): Add semicolon after weak_alias call. * sysdeps/generic/libm-alias-ldouble.h (libm_alias_ldouble_other_r_f128): New macro. (libm_alias_ldouble_other_r_f64x): Likewise. (libm_alias_ldouble_other_r): Use libm_alias_ldouble_other_r_f128 and libm_alias_ldouble_other_r_f64x. (libm_alias_ldouble_r): Add semicolon after weak_alias call. * sysdeps/ieee754/ldbl-opt/libm-alias-ldouble.h (libm_alias_ldouble_other_r_f128): New macro. (libm_alias_ldouble_other_r_f64x): Likewise. (libm_alias_ldouble_other_r): Use libm_alias_ldouble_other_r_f128 and libm_alias_ldouble_other_r_f64x. |
