Summary: assembly language instead of HLL? you kidding?

I wonder who the author is and how much programming he has done.

Some relevant points:

HLL's make it easier to program good algorithms with speedup that make
a factor of 2 look sick.

If you need to squeeze every last microsecond out of the program,
consider that normally 20% of the program takes 80% of the run time.
(Or was it 10/90?) Find the hot spots and optimize the hell out of
that, in assembler if need be. This mixed approach gets you the
advantages of HLLs most of the time and the efficiency you want.

Finally, I'm writing this compiler. It's only a student project but
already 6000 lines and growing, 1000 of which I added in the last
week.  I don't know anybody in his right mind who would suggest writing
it in assembler these days.

A good book to read is Jon Bentley's "Writing Efficient Programs".
