Bug #: 54839
Summary: INTEGER_CST is missed by uniuqify_nodes and soaks tons
of memory
Classification: Unclassified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3

patch
Because integer_cst is streamed directly, it bypasses streamer cache. It
however reffers to types and the types needs fixup.
The attached patch provokes the problem by ggc_freeing the obsoletted types and
also fixes it by adding to_fix vector. I wonder what is better option?
Do we need to stream them differently? I guess integer_csts are often 0/1 and
streaming always the whole thing seems wasteful.
