The Z83 C Compiler is an optimizing cross compiler for a language very similar to C targeted toward the TI83+. The output from the compiler may be assembled with TASM (http://home.comcast.net/~tasm/) or ZASM (http://lpg.ticalc.org/prj_zasm/).
tisdcc is a C-compiler and library for TI calculators with a z80-processor (TI-73, TI-82, TI-83, TI-83 Plus, TI85 and TI-86). It allows high-level coding for these calculators without the slow speed of TI-BASIC and without the hassle of learning asm.
The NT POSIX C Runtime Library is an IEEE standard runtime library for the NT POSIX subsystem. It can be used as a complete replacement or a side by side alternative for what is shipped with the Interix SDK.
SDCC-M08 is a Freeware, retargettable, optimizing ANSI - C compiler. New port for Motorola 68HC08/68HC908 processor family, a side branch of the original SDCC. It generates RAM sparing reentrant code, different from root SDCC. Distributed under GPL.
This project provides a tool-chain for compiling C code for the SPEAR2 processor. It comprises a C compiler (GCC), an assembler/linker, a macro assembler, a basic library and a simulator.
