powerpc-nofpu libc exports __sqrtsf2 and __sqrtdf2 symbols. The export of these soft-fp symbols is a mistake; they aren't part of the libgcc interface and GCC will never generate code that calls them. This patch makes them into compat symbols (no code built for static libc), moving their sources from the generic soft-fp sources to sysdeps/powerpc/nofpu (the underlying soft-fp FP_SQRT functionality remains of use to implement actual sqrt public interfaces, such as sqrtl / sqrtf128 for which it is used on various platforms, but __sqrt[sdt]f2 are not such interfaces). Tested with build-many-glibcs.py for relevant platforms. [BZ #18473] * soft-fp/sqrttf2.c: Remove file. * soft-fp/sqrtdf2.c: Move to .... * sysdeps/powerpc/nofpu/sqrtdf2.c: ... here. Include <shlib-compat.h>. (__sqrtdf2): Make conditional on [SHLIB_COMPAT (libc, GLIBC_2_3_2, GLIBC_2_28)]. Define as compat symbol. * soft-fp/sqrtsf2.c: Move to .... * sysdeps/powerpc/nofpu/sqrtsf2.c: ... here. Include <shlib-compat.h>. (__sqrtsf2): Make conditional on [SHLIB_COMPAT (libc, GLIBC_2_3_2, GLIBC_2_28)]. Define as compat symbol. * soft-fp/Makefile (gcc-single-routines): Remove sqrtsf2. (gcc-double-routines): Remove sqrtdf2. (gcc-quad-routines): Remove sqrttf2. * sysdeps/nios2/Makefile [$(subdir) = soft-fp] (sysdep_routines): Do not filter out sqrtsf2 and sqrtdf2. * sysdeps/powerpc/nofpu/Makefile [$(subdir) = soft-fp] (sysdep_routines): Add sqrtsf2 and sqrtdf2.
