I am trying to determine the percentage of users (in the following
three environments) who actually use assembler to some degree:
1. UNIX systems programmers
2. UNIX applications programmers
3. students and faculty in a university UNIX environment
The question is whether or not C is a viable alternative to using assembler.
It seems that the SysV manuals are trying to dissuade UNIX programmers from
using assembler. Is this true?rej@cornell.UUCP (04/19/84)
C can replace assembler. The only use for assembler on VAXen is to write the context switching routines and to improve the speed of a few commonly used subroutines. People that I know programming in C on a 68000 never seem to use assembler. The Cornell Program Synthesiser is written in C and runs on many PDP-11s across campus. Its device drivers and overlay routines are written in C, with only the process switching routines being in assembler. Ralph Johnson cornell!rej

Also used in the C library for the system interface routines, but that's
not the kernel...
Nooooo.... Not ANOTHER set of interface routines.....
