Cool.  I wonder if this was the same problem that we discussed while
I was in Sunnyvale earlier this year...

Did you answer Corey's other questions?

Regardless, the patch looks good.  Please install it.

Thanks Cory & Richard!

haifa memory explosion patch

[Richard Henderson]

Thanks to Corey Kosak and an outstanding bit of detective work
(report attached), it is clear that haifa needs to be a good bit
more careful in general with its memory usage.

With the attached patch, memory usage for the example in

  http://www.cygnus.com/ml/egcs-bugs/1998-Jan/0108.html

is reduced from > 145MB (vm exhausted) to 14MB.

This patch (dated March 3) doesn't seem to have made it into the CVS
tree (egcs_1_00_branch).  Is it in the snapshot for 1.0.2?

The current CVS repository has:
/haifa-sched.c/1.17.2.1/Sat Feb 14 09:40:01 1998//Tegcs_1_00_branch

I wasn't planning on installing the haifa memory patch on the
release branch....
