Vasm PPC std

vasm is a portable and retargetable assembler to create linkable objects in
various formats or absolute code. Multiple CPU-, syntax and output-modules can
be selected.

Many common directives/pseudo-opcodes are supported (depending on the syntax
module) as well as CPU-specific extensions.

The assembler supports optimizations (e.g. choosing the shortest possible branch
instruction or addressing mode) and relaxations (e.g. converting a branch to an
absolute jump when necessary).

Most syntax modules support macros, include directives, repetitions, conditional
assembly and local symbols.
