Subject: [Bug tree-optimization/22488] [4.1 Regression] push_fields_onto_fieldstack calculates offset incorrectly
Date: Tue, 04 Oct 2005 12:30:00 -0000	[thread overview]
Message-ID: <20051004123047.5374.qmail@sourceware.org> (raw)
In-Reply-To: <bug-22488-7559@http.gcc.gnu.org/bugzilla/>



------- Comment #38 from dberlin at gcc dot gnu dot org  2005-10-04 12:30 -------
As a 4.1 kludge, i can make the points-to analyzer do what it does for unions,
which is to glob everything to a single variable for those classes where it has
found two fields it thinks overlap.

This will lose alias precision, but it won't be worse than what 4.0 was.
