That is correct. > Oh! Now I read docs about it. > It seems that PARTIAL are compiletime option only for JIT. So it seems that > disabling of this calculations may matter to JIT only. May be it can reduce a > bit some compile time in some cases. At compile time, you do not know if JIT is going to be used. In PCRE1 these calculations were done in a separate pcre_study() call. However, they are not expensive calculations and for PCRE2 they just happen automatically. > At match time there are start optimizations that use this calculations. Yes. > It seems that this optimizations are disabled when PARTIAL option used. Yes. Philip -- Philip Hazel -- ## List details at https://lists.exim.org/mailman/listinfo/pcre-dev
