Hi Paul,
Yes, that's fine for trunk. I wonder if it is worth being explicit that linear congruential pseudo-random number generators can and do fail at -O3?
I don't think we should put this into the docs, because that can change at any time. Maybe into porting_to.html, though (where I have only mentioned this as a general issue with linear congruential generators, without mentioning specific options. Current text can be seen at https://gcc.gnu.org/gcc-13/porting_to.html ). Hm.... Best regards Thomas
