--- Comment #8 from Kazumoto Kojima <kkojima at gcc dot gnu.org> --- (In reply to John Paul Adrian Glaubitz from comment #7) > What do you mean? Using -O1 will trigger all kinds of bugs? Or is it rather > about PR target/66358? Just my 2 cents. Even on the primary targets, bootstrap with other than '-g -O2' are not so well tested. Most packages are built with -O2, aren't they? After all, -O1 should work but not safer than -O2, IMO. O2 does many optimizations, and some of them might cause bug. OTOH, some of them simplify the intermediate code. With -O1, we could see highly complex intermediate code in some cases and they might cause problem. We have just seen an example in this PR.
