libgcc
* config/rs6000/sfp-machine.h:
(_FP_DECL_EX): Declare _fpsr as a union of u64 and double.
(FP_TRAPPING_EXCEPTIONS): Return a bitmask of trapping
exceptions.
(FP_INIT_ROUNDMODE): Read the fpscr instead of writing
a mystery value.
(FP_ROUNDMODE): Update the usage of _fpscr.
Okay.
Thanks, David
