.SH DESCRIPTION
|
|
|
|
|
Most programs involved with the EM project only produce and accept
|
|
|
|
|
EM programs in compact form.
|
|
|
|
|
These files are only machine readable.
|
|
|
|
|
A description of this compact form can be found in [1].
|
|
|
|
|
To inspect the code produced by compilers or to patch them for one reason
|
|
|
|
|
or another, you need human readable assembly code.
|
|
|
|
|
Em_decode will do the job for you.
|
|
|
|
|
.PP
|
|
|
|
|
Em_decode accepts the normal compact form in both optimized and
|
|
|
|
|
unoptimized form
|
|
|
|
|
.PP
|
|
|
|
|
Sometimes you have to make some special routines directly
|
|
|
|
|
in EM, for instance the routines implementing the system calls.
|
|
|
|
|
At these times you may use em_encode to produce compact routines
|
|
|
|
|
out of these human readable assembly modules.
|
|
|
|
|
.PP
|
|
|
|
|
The first argument is the input file.
|
|
|
|
|
The second argument is the output file.
|
|
|
|
|
Both programs can act as a filter.
