em_opt \- EM peephole optimizer
|
|
.SH SYNOPSIS
|
|
/usr/em/lib/em_opt [-Ln] [ argument ]
|
|
.SH DESCRIPTION
|
|
Em_opt reads a compact EM-program, argument or standard input,
|
|
and produces another compact EM program on standard output
|
|
that is functionally equivalent,
|
|
but smaller.
|
|
Some other functions are here that make this program mandatory
|
|
before running a codegenerator,
|
|
it may be left out when interpretation is wanted.
|
|
Flags recognized are:
|
|
.IP -L
|
|
Make a library module.
|
|
This means that the output will start with a message giving
|
|
the names of all exported entities in this module.
|
|
.IP -n
|
|
Do not optimize.
|
|
No peephole optimizations will be performed,
|
|
other functions will be carried out.
|
|
