> I am using gnatmake 9.3.0 and gprbuild community edition 2021. The Ada executable from gnatmake is about 50% smaller than that of gprbuild and runs much slower than the gprbuild version. Is gnatmake deprecated, obsolete, or not maintained?
It looks like the compiler, linker & binder options that, in your case, gnatmake sends to GNAT, are different than those gprbuild sends, especially optimization options.
What are the command line options to gnatmake you are using ? And to gprbuild ?
