obcpl (BCPL compiler)
This is an x86 (IA-32) port of the "classic" old BCPL compiler (around
1980) from the Tripos Research Group at Cambridge University.
As a real, working computer language implementation, that can be
studied, modified, and played with, this old BCPL compiler has a good
deal to recommend it. The compiler frontend consists of only about
2000 lines of BCPL code, and (as supplied here) compiles to a static
(fully-linked) x86 binary that is less than 36000 bytes in size.
x86_64 note: obcpl doesn't require multilib on Slackware64. It only
generates 32-bit x86 code, but the binaries it creates are 100%
statically linked, and will run fine on Slackware64 without multlib.
The package includes:
- The BCPL compiler itself (/usr/bin/obcpl and the support files in
/usr/lib(64)?/obcpl)
- The utilities:
- obcpl-cmpltest: compiler test
- obcpl-gpm: macro generator
- obcpl-xref: cross referencer
- The sources for the utilities
- Example code (Hello World and a factorial calculator)
- The obcpl documentation, including manual.txt and standard.txt
