Open64
Open64 is an open source, optimizing compiler for the Itanium
and x86-64 microprocessor architectures.
The Open64 compiler suite includes optimizing compilers and
runtime support for C, C++ and FORTRAN 77/90/95. These compilers
produce code that follows the corresponding ABI on IA-32/Linux,
x86_64/Linux and IA-64/Linux and be compatible with the latest GCC
revision. This means that objects produced by the Open64 compilers can
link with objects produced by other ABI compliant compilers.
Open64 is used in a number of research projects, such as the
Unified Parallel C (UPC) and speculative multithreading work at various
universities.
