------- Comment #31 from danglin at gcc dot gnu dot org 2006-06-03 19:47 -------
The test will fail on any hppa target with the addition of "-fPIC".
I tend to think the use of the 'X' constraint is bogus, and that the
test should be xfailed on hppa64. While it might be possible to add
support to handle this particular reload, it's not something that's
needed for the patterns in pa.md. As Kenner noted, combine doesn't
check that anything it generates is valid.
