[Bug bootstrap/37859] Bootstrap failure on mips64octeon-unknown-linux-gnu

[vmakarov at redhat dot com]

------- Comment #2 from vmakarov at redhat dot com  2008-11-14 03:13 -------
  Removing redundant stores could be done by solving a dataflow
problem.  Unfortunately such global solution would complicate IR
flattening.

  I am going to submit a patch soon which solves the problem by
prohibiting removing stores if there is path from a destination loop
(pseudo assigned to memory there) to the header of source loop (pseudo
assign to hard register there) containing basic blocks of non-parents
(grandparents) of the source loop.  That is the assumption on which
ira-build.c:ir_flattening code works.
