Richard Guenther <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Target Milestone|--- |4.6.0 --- Comment #2 from Richard Guenther <rguenth at gcc dot gnu.org> 2010-10-03 19:51:59 UTC --- The conditional store pass is confused about *D.1952_4 = 0; D.1953_5 = i_1(D) & 1; if (D.1953_5 != 0) goto <bb 3>; else goto <bb 4>; <bb 3>: MEM[(char * {ref-all})D.1952_4] = ""; because that assignment is an array-to-array assignment (not exactly optimal result of constant-folding).
