Even then, what failure was it? gimplify_pure_cond_expr gimplifies all the 3 arguments anyway, so if they have side-effects, they just end up being evaluated into temporaries which are then used in the COND_EXPR. Anyway, can you please follow up to Diego's mail, either agree to remove that, or justify it? Apart from a typo in ChangeLog entry that was his only objection and it would be good to have this P1 fixed ASAP. > yes, although making it work that way is more complicated; it would require > changes in the # of iterations analysis, to get Ok. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34005
