432183 - Remove obsolete ESC files

Status: RESOLVED FIXED

(Tamarin Graveyard :: Self-hosting compiler (ESC), defect)

Description

[Lars T Hansen]

I propose that the following ESC files are obsolete and should be removed or moved to a "probabletrash" directory.  Please let me know what you think.

In esc/src:

esc1-r.es
esc1-t.es{,.abc}
esc2-r.es
esc2-t.es{,.abc}
esc3-r.es
esc3-t.es{,.abc}
esc-verify.es
bytes-es4ri.es
util-es4ri.es
eval.es
abcdec.es
abc-decode.es{,.abc}

In esc/build:

abcdecode.sh
esc-env.ast
esc-r.sh
esc1-r.sh
esc1.sh
esc2-j.sh
esc2-r.sh
esc2.sh
esc3-r.sh
esc3.sh

I think the only ones here that could be remotely controversial are abcdec.es, abc-decode.es, and abcdecode.sh.  They comprise the .asm -> .abc processor.  I've never used it; I believe it does not currently work (a test a couple of weeks ago produced only pain & suffering); and though there might be a need for it, what that need might be is not clear to me at the moment.

Most of these files were used for bootstrapping the compiler. I don't know the state of the decode programs mentioned, but in principle they could be useful. I'd say keep them around unless Erik thinks otherwise.

Pushed.  I kept the assembler, but I removed comp-esc.sh -- it's obsolete.
