+.SH NAME

|
|
+em_cg \- EM to assembly code translator
|
|
|
+.SH SYNOPSIS
|
|
|
+em_cg [-d\fIn\fP] [-p\fIn\fP] [-w\fIn\fP] [-u\fIfile\fP] [ infile [ outfile ] ]
|
|
|
+.SH DESCRIPTION
|
|
|
+Em_cg reads a compact EM-program, argument or standard input,
|
|
|
+and produces an assembly program on argument or standard output
|
|
|
+for the machine that is in its name.
|
|
|
+Flags recognized are:
|
|
|
+.IP -d\fIn\fP
|
|
|
+Run in debugging mode, debugging level \fIn\fP,
|
|
|
+only possible when the translator is compiled in the right way.
|
|
|
+.IP -p\fIn\fP
|
|
|
+Set the ply to \fIn\fP, default 1.
|
|
|
+The ply is the maximum lookahead depth the code generator may take.
|
|
|
+Effects of this flag are machine dependent.
|
|
|
+.IP -w\fIn\fP
|
|
|
+Set the weight percentage for size to \fIn\fP %, default is 50.
|
|
|
+This sets the size/time tradeoff in the codegenerator.
|
|
|
+Effects are again machine dependent.
|
|
|
+.IP -u\fIfile\fP
|
|
|
+Take the \fIfile\fP as a bitmap giving 1 bits for untested code rules
|
|
|
+and write the \fIfile\fP at end of code generation,
|
|
|
+substituting zero bits for rules used.
|
|
|
+Give a list of untested rules on standard error, unless the -u
|
|
|
+was given as -U.
|
|
|
+Only possible if the -d flag was given to cgg(VI).
|
|
|
