Questions tagged [armcc]

Questions regarding armcc, C/C++ compiler that is part of proprietary ARM compiler tool-chain, version 5 and below. For questions regarding ARM Compiler 6, use armclang tag instead.

The ARM C compiler is a mature, industrial-strength compiler, based on Codemist Ltd's multi-target, multi-language compiler suite (also known as the Norcroft C compiler).

By default the ARM C compiler compiles ANSI C as defined by American National Standard for Information Systems - Programming Language C, X3J11/90-013, Feb 14, 1990.

The ARM C compiler also has a pcc mode, which accepts the dialect of C used by Berkeley Unix. In this mode the compiler has been used to build a complete ARM-based Unix system (the RISCiX system).
