So it is very unlikely that they will hit this problem. In fact if we enable this workaround in 4.3 we give them a false sense of security that this "feature" is maintained. It also gives them a false sense of the severity of this problem which is very low, very much lower than any other random wrong-code bug we discover. Marking as ABI issue, but not wrong-code (it is not). Marking as regression. I vote for "RESOVED INVALID". -- rguenth at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 Keywords| |ABI Last reconfirmed|0000-00-00 00:00:00 |2008-04-29 14:46:20 date| | Summary|cld instruction is not |[4.3/4.4 Regression] cld |emitted anymore. |instruction is not emitted | |anymore.
