How good are your diagnostics compared to GCC -O2, plus -Wall and -W? Some diagnostics are not produced or don't work well without optimization, because the the same analysis that goes into optimization also goes into proofs connected to diagnostics. For instance, some code look like might use a variable without initializing it, under some conditions. The optimizer can rule out of those conditions (e.g. by transforming the code in a way that makes it obvious that the use of the variable is not reached without crossing an assignment to it.) -- TXR Programming Language: http://nongnu.org/txr Cygnal: Cygwin Native Application Library: http://kylheku.com/cygnal Mastodon: @Kazinator@mstdn.ca
