Other Compilers

Other compilers that can be used for OS development:

• Ken Thompson's portable compiler collection for Plan 9, now available in *nix systems as part of the Go toolchain.
• Borland Turbo C - Only useful for 16bit OSes - Available from the Borland/Embarcadero Antique Software Museum
• Free Pascal Compiler - Available at http://www.freepascal.org. Only issue is that you need to write your own RTL to not call system functions.
• FreeBasic - 32-bit BASIC compiler (not an interpreter) that has many new improvements that will help in OS construction such as pointers and inline assembly, Available at http://www.freebasic.net
• Intel C/C++ Compiler. Commercial (free 30-days trial). Available for Linux, Windows, and OS X. It is very compatible with MSVC++ (I haven't spent even an hour to change compiler) and GCC (as they say). Famed for it's heavy optimisation. Targets IA-32, x86-64, IA-64, and XScale. Recommended by Intel for systems and applications programming (info on this would be helpful). http://software.intel.com/en-us/intel-compilers/
• PCC/Portable C Compiler - http://pcc.ludd.ltu.se/
• Clang a front end for LLVM - http://clang.llvm.org/
