gcc-4.0_branch (Debian 4.0.2-6), only with 20060128 (Debian 4.0.2-8)

------- 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.

I guess the bug was instroduced by the removal of the
SECONDARY_MEMORY_NEEDED_RTX
define. Without it reload isn't smart enough to use SImode for the
general to floating-point register copy. Probably, adding alternatives to
do the copy will fix the problem, and just maybe if the alternatives are
disparaged reload won't use them. Yuck.

Yes. However, I want to complete testing on on both hpux and linux.
The biggest risk in this change is that it might require support for
reloads that weren't needed before since we're now explicitly allowing
QI and HI mode values into the FP registers.
