commit 32d372d548122b224ec63a520a780d9227094a48
Author: Joseph Myers <joseph@codesourcery.com>

    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.
