------- Comment #7 from rguenth at gcc dot gnu dot org 2010-06-26 09:28 -------
Another way would probably be to ensure that f0 always appears as first operand
by adjusting the various patterns in ia64.md to only allow fr_reg_operand
in the 2nd operand slot of addsf3 (and maybe other patterns).
At least the *maddsf4 pattern incorrectly allows fr_reg_or_fp01_operand
for the third operand which is not correct if signed zeros are supported.
HJ, can you investigate?
