[fpc-devel] Question on updating FPC packages

[J. Gareth Moreton]

Another point to bring up...

I could easily write a cross-platform complex number library that is 
designed to take advantage of vector registers whenever possible for the 
absolute best performance, but there comes a problem of having multiple 
libraries that do the same thing and not really sticking to any 
standard.  People tend to stick to what they're familiar with as well, 
and if a tool already exists, no matter how inefficient it is, people 
will use that instead. That's why I opted to update an existing library 
while doing my best to ensure Pascal code isn't broken.  When it comes 
to assembly language, all bets tend to be off anyway, although once 
again, I argue that using assembly language to directly interface with 
the complex number routines is not a realistic situation, since if 
you're writing things in assembly language, complex numbers is one of 
those constructs that you would write in assembler as well for the sake 
of speed and efficiency.

Long story short... why would people use or update their code to use a 
new complex number library when one that's been tried and tested (albeit 
out of date) already exists?
