------- Comment #5 from vmakarov at redhat dot com 2008-10-14 19:50 -------
Updating of total_conflict_hard_regs in ira-build.c::ira_flattening was
completely wrong. So I rewrite the calculation of total_conflict_hard_regs and
total_no_stack_reg_p. It is now done from the scratch. The code became more
readable and there is no visible slowdown of IRA.
I'll send a patch solving the PR later today.
