------- Comment #3 from danglin at gcc dot gnu dot org 2006-02-13 19:08 -------
Regarding comment #2, while it's possible that removing
the SECONDARY_MEMORY_NEEDED_RTX define has had an effect,
we have never had support in pa.md to load an HImode value
into a floating-point register. The other changes in the
patches mentioned don't affect HImode.
It seems as reload isn't respecting HARD_REGNO_MODE_OK
(see VALID_FP_MODE_P in pa32-regs.h). The reason for
excluding HImode (and QImode) values from the FP
registers is you can't do anything with them, and copying
to/from the general registers has to be done thorugh memory.
Thus, it's better to use the stack.
