------- Comment #6 from rguenth at gcc dot gnu dot org 2008-01-06 09:56 -------
The problem is we have loads of unpartitionable SFTs. There are workarounds
possible that only might affect performance of generated code, for example
you can use --param salias-max-array-elements=0, which will reduce the number
of unpartitionable SFTs somewhat. Or as a more big hammer, disable generating
SFTs completely by --param max-fields-for-field-sensitive=0.
