------- Comment #11 from fxcoudert at gcc dot gnu dot org 2009-05-05 08:18 -------
As far as I can say, the targets with this problem are: avr, bfin, h8300,
picochip and sh (for some subtargets of sh).
On avr, bfin, h8300 and picochip, we're doomed anyway because there is no
double-sized type at all. On sh, we could use long double math calls.
I'm making this into an enhancement; it will probably be very painful, because
most of the front-end assumes FLOAT_TYPE_SIZE == 32 and DOUBLE_TYPE_SIZE == 64.
