Description:

Yasm is a complete rewrite of the NASM assembler under the "new" BSD
License (some portions are under other licenses, see COPYING for
details). It is designed from the ground up to allow for multiple
assembler syntaxes to be supported (eg, NASM, TASM, GAS, etc.) in
addition to multiple output object formats and even multiple
instruction sets. Another primary module of the overall design is an
optimizer module.

The core focus of Yasm is not the "yasm" commandline frontend; rather,
it is the Libyasm library and associated LoadableModules. Libyasm and
the modules are intended for reuse in other sorts of programs dealing
with code at the assembly level (compilers, debuggers, etc). Someday,
libyasm may be packaged separately from the rest of Yasm.
