TMG(VI) 10/21/72 TMG(VI) NAME tmg - compiler-compiler SYNOPSIS tmg name DESCRIPTION Tmg produces a translator for the language whose parsing and translation rules are described in file name.t. The new translator appears in a.out and may be used thus: a.out input [ output ] Except in rare cases input must be a randomly addressable file. If no output file is specified, the standard output file is assumed. FILES name.s: assembly language version of name.t /usr/lib/tmg: the compiler-compiler /usr/lib/tmg[abc], /lib/libs.a: libraries alloc.d: scratch file for table storage SEE ALSO A Manual for the Tmg Compiler-writing Language, internal memorandum. DIAGNOSTICS Syntactic errors result in "???" followed by the offending line. Situations such as space overflow with which the Tmg processor or a Tmg-produced processor can not cope result in a descriptive comment and a dump. AUTHOR M. D. McIlroy BUGS Footnote 1 of Section 9.2 of Tmg Manual is not enforced, causing trouble. Restrictions (7.) against mixing bundling primitives should be lifted. Certain hidden reserved words exist: gpar, classtab, trans, goto, alt, salt. Octal digits include 8=10 and 9=11.
