Just curious: perl + C + asm, any?

[Michele Dondi]

As of the subject, I was wondering if anyone has ever written a binary
module for perl that in turn had some routines written in assembler,
for efficiency reasons.

Why not? Take a module which uses an externally available C code
which uses ASM (such as Math:ari). This is a beast to compile,
though, since Perl's Config.pm does not know how to run assembler...

Or, less strict, take any Perl module which links with a library which
is compiled from assembler code (such as Math::GMP).

Hope this helps,

The efficiency margin of assembly over well written C is usually very
small, and comes at the cost of portability. Unless the algorithm is
written to utilize architecture specific features it's probably not
worth the trouble.

This is exactly what I meant! Thanks, I would have thought that to
much a more rare thing though.
