commit 7e16a5d1d19effc7b2775942f592520cfff03d92
Author: Joseph Myers <joseph@codesourcery.com>

    Use libm_alias_double for dbl-64 fma.
    
    This patch makes dbl-64 fma use libm_alias_double.  The ldbl-opt
    version is removed.  The sparc32 version no longer needs to handle
    compat symbols, while alpha needs a new wrapper to avoid getting the
    ldbl-128 version (where ldbl-opt is earlier in the list of sysdeps
    directories, so previously fma came from there).
    
    Tested for x86_64, and tested with build-many-glibcs.py that installed
    stripped shared libraries are unchanged by the patch.
    
    	* sysdeps/ieee754/dbl-64/s_fma.c: Include <libm-alias-double.h>.
    	(fma): Define using libm_alias_double.
    	* sysdeps/ieee754/ldbl-opt/s_fma.c: Remove file.
    	* sysdeps/sparc/sparc32/fpu/s_fma.c: Do not include
    	<math_ldbl_opt.h>.
    	(fmal): Do not define as compat symbol here.
    	* sysdeps/alpha/fpu/s_fma.c: New file.
