If I'm right in thinking, things like "fpc_abs_real" are fallback
functions that have to be overridden by a platform-specific
implementation, and return runtime errors if they aren't implemented. In
many cases, such internal compiler routines are not called at all
because there's a direct instruction available in the architecture (e.g.
for integer min and max functions, AArch64 has SMIN and SMAX
respectively, but x86 doesn't have such direct operations).
Thanks.
Btw, the "compilerproc" modifier is still not documented. Google found
my post from 8 years ago asking a similar question. 🙃
I documented it.
Michael.
