Kyle would know.

The JALv2 compiler does appear to "take advantage" of PIC HW, i.e.=20
multiply if it's an 18F rather than a 10F uses the multiply instruction=20
and multiply hardware.

It's a superb optimising compiler. Unless you are Olin, you will not do=20
as well in Assembler even if the compiler is ignoring the odd device=20
specific instruction.

I've found all the C compilers produce much larger and sometimes buggy code=
..

I've done Assembler since 1979 and done PIC 16F877 assembler projects.=20
I'd not use anything else now for Traditional PIC (10F to 18F).

Also in unlikely event (once in last 4 years or so for me?)  you need=20
assembler you can use it inline.
