Subject: m68k: Fix fmod/fmodf infinite recursion (BZ 34508)
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=bb213471bedc177b8efd3178584137fb81cc976a;p=thirdparty%2Fglibc.git

m68k: Fix fmod/fmodf infinite recursion (BZ 34508)

Commits 6deadd4eb6a and ade9f30ce27 changed m68k fmod to call
__m81_u(fmod), instead of the mathimpl.h inline
__m81_u(__ieee754_fmod) (that wraps the m68k fmod instruction).
This leads to infinite recursion.
