Sample Program


Y - General purpose language syntactically like RATFOR, semantically like C. Lacks structures and pointers. Used as a source language for the Davidson/Fraser peephole optimizer.

Yaa - Yet Another Assembler - Macro assembler for GCOS 8 and Mark III on Bull DPS-8 machines. Available from Bull as part of U Waterloo Tools package (maintained by <pjf@thinkage.on.ca>).

yacc - Yet Another Compiler Compiler. Language used by the Yacc LALR parser generator. "YACC - Yet Another Compiler Compiler", S.C. Johnson, CS TR 32, Bell Labs (Jul 1975). Implementations: ayacc - UC Irvine. written in Ada, produces Ada output ftp://liege.ics.uci.edu/pub/irus/aflex-ayacc_1.2a.tar.Z Bison - from GNU ftp://prep.ai.mit.edu/pub/gnu/bison-1.21.tar.Z Bison++ - produces C++ output. ftp://psuvax1.cs.psu.edu/pub/src/gnu/bison++-1.04.tar.Z perl-byacc - produces perl output ftp://ftp.sterling.com/local/perl-byacc1.8.2.tar.Z SASL-yacc - "Yacc in SASL - An Exercise in Functional Programming", Simon Peyton-Jones, Software Prac & Exp 15:807-820 (1985). Mentions also a BCPL implementation. yacc++ - 1990. An object-oriented rewrite of yacc, supports regular exp- ressions, produces an LR(1) parser. "YACC Meets C++", S.C. Johnson, USENIX Spring '88 Conf. Chris Clark, Compiler Resources Inc, Barbara Zino <bz%compres.UUCP@primerd.cv.com> (508) 435-5016.
