    Ox: Attribute Grammar Compiling System

    Ox: Attribute Grammar Compiling System

    Ox is an attribute-grammar evaluator generator.

    Ox is an attribute grammar compiling system that augments Lex and Yacc specifications with definitions of synthesized and inherited attributes written in a combination of Ox and C/C++ syntax. From these augmented specifications, Ox generates ordinary Lex and Yacc specifications that build and decorate attributed parse trees. The user can specify parse-tree traversals for easy ordering of side effects such as code generation. Ox handles the tedious and error-prone details of writing code for parse-tree management, so its use eases problems of security and maintainability associated with that aspect of translator development.

    MinForth

    MinForth

    A minimalistic but complete standard Forth compiler in C

    MinForth V3.4 is a classic Forth system with command-line interface. Development resource requirements are minimal. A source text editor and a C compiler are sufficient. By design no toolchain is required to adapt or rebuild MinForth. A complete rebuild takes only few seconds. Current sources are for Windows and Linux (32-bit or 64-bit). MinForth primitive definitions are written in mixed Forth and C language and are transpiled to pure C code. Main but not exclusive application for the transpiler is to build the MinForth V3.4 high-level Forth compiler. MinForth V3.4 is widely conformant to the Forth-2012 draft standard and passes the usual test suites. Feedback and bug reports are welcome per - Usenet forum https://groups.google.com/forum/#!forum/comp.lang.forth - email to minforth@gmx.net

    Provide latest GNU toolchain for Symbian developers

    Provides bleeding-edge GNU toolchain for Symbian. GCC still supports Symbian therefore project active. All thanks for me and my hard-work GCC still supports Symbian. Benefits: moderm libraries require new compiler features and languange standarts. More software will be coming to small old phones! Binutils and GDB stop support Symbian and last provided versions are 2.29.1 and 10.2
