- .SH NAME
- em_nopt \- EM peephole optimizer
- .SH SYNOPSIS
- .B ~em/lib.bin/em_nopt
- [ inputfile [ outputfile ] ]
- .SH DESCRIPTION
- Em_nopt reads a compact EM-program inputfile or standard input,
- and produces another compact EM program on outputfile or standard output
- that is functionally equivalent,
- but smaller.
- This program is a faster replacement for the program em_opt but does not
- perform some other functions that that program performed and were required
- before running a codegenerator. These operations are now performed by the
- front ends and the EM_CODE(3) module. The old program is still required
- for front ends that do not use the new mechanisms or for making a library
- module.
- Usually this program need not be run as the front end will perform the
- equivalent optimizations using the library module em_opt(3).
