The Amsterdam Compiler Kit is a fully-featured retargetable compiler toolchain. It will cross-compile ANSI C, K&R C, Pascal, Modula-2, Occam, Fortran and Basic for a number of architectures including, but not limited to, the 6500, 68000, Z80, i80, i86, i386, and PDP-11. It provides a complete development environment including preprocessors, compilers, assemblers, linkers, librarian tools, and target download tools.
The XDS product line facilitates software development in the Modula-2 and Oberon-2 languages. It includes native compilers for Intel x86 and "via C" cross-compilers that produce ANSI C source, allowing you to target virtually any platform. The TopSpeed Compatibility Pack add-on aids porting programs written in the TopSpeed Modula-2 dialect to XDS.
Critical Mass Modula-3 is an easy-to-use and easy-to-install Modula-3 system that contains considerable enhancements over its ancestor DEC SRC Modula-3, including modules loadable at runtime, implicit exceptions (even for checked runtime and gc failures), COM-compatible object layout (for Win32), Unicode support, and 64-bit support for 64-bit machines.
