The standard was written with those optimizations in mind, but they didn't start making their way into the popular compilers until the implementations became advanced enough to include them. That also partly results from hardware improvements in the past decades making it possible for compilers to do more stuff in a compilation run, and making development easier in general. I'd be curious to know whether the optimizations were already present in the Cray compilers of the 1980's-90's. > C compiler maintainers of those days, such as Richard Stallman, knew > how to optimize without breaking lots of code. I might ask him about this next time I get a chance. I know that he is skeptical of the concept of writing reliable programs in C these days, probably for about the same reasons as me. >>I remember one commenter [on Regehr's blog] responding > This commenter was totally wrong. Unfortunately, I could not longer > point out how wrong he was and why in the comments section, because > one could no longer post comments when I saw that blog entry. A typical reason for closing old comment sections is to avoid having to deal with automated spam in them, on the basis that on-topic discussion has mostly quieted down. People still read that entry, so if you can write a reasonably informative response backed by evidence, it might be worth sending it to Regehr and asking him to post it. > Yes, that would be their reaction, which shows that they either don't > know how people program, or they pretend not to know it. The current entry on Regehr's blog mentions someone is working on a precise semantics of C the way people actually use it. That might be a reasonable thing for compiler writers to target.
