Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Keywords| |needs-testcase --- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> --- As noted in the bug what PRE considers possibly trapping is quite conservative (and has to, as no flow-sensitive info can be used easily). But the fix was a correctness one so I'm not sure what we can do. Needs a testcase showing the 400.perlbench case for analysis.
