------- Comment #5 from rguenth at gcc dot gnu dot org 2006-07-21 10:41 -------
On the mainline we produce
Variable: D.1848, UID 1848, float *, symbol memory tag: SMT.4
Variable: D.1851, UID 1851, const float *, symbol memory tag: SMT.4
while 4.1 branch does
Variable: D.1604, UID 1604, float *, type memory tag: TMT.5
Variable: D.1607, UID 1607, const float *, type memory tag: TMT.6
anyones bell ringing?
