With success I have built and used an fpc-3.3.1 based LLVM compiler.
The FPC LLVM Wiki <https://wiki.freepascal.org/LLVM> [1] says that
"the compiler itself on x86-64 is about 10% faster when compiled with
LLVM on an Intel Haswell processor, or 18% if you also enable
link-time optimization." I could not find how to do that (build the
compiler itself with llvm) as it requires starting with an fpc-3.2.2
compiler.
You can add OVERRIDEVERSIONCHECK=1 to the make command disable the
version check. It's not advertised because using it in general is not
supported (only when building the exact same FPC revision from which
the compiler was built).
Thanks, I will try that.
