In this directory is a complete interpreter for EM-code on a
|
||
|
|
PDP 11, written in Unix assembly language.
|
||
|
|
The interpreter is split up in 7 files, em.v1 up to em.v7.
|
||
|
|
There exist assembler options .test .opfreq .flow .count .prof
|
||
|
|
and .last.
|
||
|
|
.test tests undefined integers, bad arrays etcetera
|
||
|
|
.opfreq makes a table of the usage of othe em-opcodes
|
||
|
|
.flow makes a table of the used lines
|
||
|
|
.count makes a count table of the used lines
|
||
|
|
.prof estimates the amount of time spent on each source line
|
||
|
|
.last gives a table of the last executed lines and files
|
||
|
|
The interpreter writes its runtime information on a file
|
||
|
|
em_runinf, which is converted to human readable files
|
||
|
|
em_last, em_opfreq, em_profile, em_flow and em_count by
|
||
|
|
the program eminform, for which we also have an assembler
|
||
|
|
source in this directory.
|
||
|
|
Because the size of the interpreter just exceeds 8k, it is
|
||
|
|
advisible to have either .prof or .test turned off on a machine
|
||
|
|
without separate I and D when a large user program is running.
