.SH SYNOPSIS
|
|
|
|
|
~em/lib/em_nopt [ inputfile [ outputfile ] ]
|
|
|
|
|
.SH DESCRIPTION
|
1987-07-10 14:16:32 +00:00
|
|
|
Em_nopt reads a compact EM-program inputfile or standard input,
|
1987-07-10 09:08:31 +00:00
|
|
|
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(3ACK) 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).
