- In this directory is a complete interpreter for EM-code on a
- PDP 11, written in Unix assembly language.
- 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.
