But I don't want to rely on people using GCC/Clang. > Three copies of the same function... I don't know... Previously, there was a copy of the function for *every* library module. In early PCRE1 days there were only one or two. Now there would be around 30 copies! What I have just done gives each library (8-bit, 16-bit, 32-bit) its own single copy, and pcre2test and pcre2grep also each have a copy. In each of the latter two programs, there is only one call to memmove(). In pcre2test, since it "knows" about the libraries, I could have juggled things to make use of an internal library copy, but pcre2grep is a clean PCRE2 application, so can't do that. It could be re-jigged to do the one job inline, but having the function available means it will all work if memmove() is used somewhere else in pcre2grep in the future - I certainly expect to have memmove() when I'm coding.
