Restore sparc32 copysignl, fabsl, fmal compat symbols (bug 22229).
32-bit SPARC libm should have compat symbols for copysignl (GLIBC_2.0), fabsl (GLIBC_2.0), fmal (GLIBC_2.1), pointing to the double functions; they were present in glibc 2.8, for example, but are now missing, probably when optimized SPARC function implementations were added without appropriate compat symbol handling. The same applies to copysignl in libc. This patch restores those compat symbols. Tested with build-many-glibcs.py for sparcv9-linux-gnu. [BZ #22229] * sysdeps/sparc/sparc32/fpu/s_copysign.S: Include <math_ldbl_opt.h> (copysignl): Define as compat symbol at version GLIBC_2_0 for libm and libc. * sysdeps/sparc/sparc32/fpu/s_fabs.S: Include <math_ldbl_opt.h>. (fabsl): Define as compat symbol at version GLIBC_2_0 for libm. * sysdeps/sparc/sparc32/fpu/s_fma.c: Include <math_ldbl_opt.h>. (fmal): Define as compat symbol at version GLIBC_2_1 for libm. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_copysign.S: Include <math_ldbl_opt.h> (copysignl): Define as compat symbol at version GLIBC_2_0 for libm and libc. (compat_symbol): Undefine and redefine. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_fabs.S: Include <math_ldbl_opt.h> (fabsl): Define as compat symbol at version GLIBC_2_0 for libm. (compat_symbol): Undefine and redefine. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_fma.c [HAVE_AS_VIS3_SUPPORT]: Include <math_ldbl_opt.h>. [HAVE_AS_VIS3_SUPPORT] (fmal): Define as compat symbol at version GLIBC_2_1 for libm. * sysdeps/unix/sysv/linux/sparc/sparc32/libc.abilist: Add GLIBC_2.0 copysignl symbol. * sysdeps/unix/sysv/linux/sparc/sparc32/libm.abilist: Add GLIBC_2.0 copysignl and fabsl and GLIBC_2.1 fmal symbols.
