2013-06-30 Joseph Myers <joseph@codesourcery.com>
* sysdeps/m68k/dl-trampoline.S (FMOVE): Define conditional on
[__mcoldfire__] and [__mcffpu__].
(FPSPACE): Likewise.
(_dl_runtime_profile): Save and restore %fp0 with FMOVE, only if
[FMOVE]. Use FPSPACE in stack offsets.
2013-06-28 Joseph Myers <joseph@codesourcery.com>
* sysdeps/m68k/fpu_control.h: Fix preprocessor indentation.
