dynasm 1.2.3

A plugin for assembling code at runtime. Combined with the runtime crate dynasmrt it can be used to write JIT compilers easily.
Documentation
The dynasm crate contains the procedural macros that power the magic of dynasm-rs. It seamlessly integrates a full dynamic assembler for several assembly dialects with rust code. As this is a proc-macro crate, it only exports the `dynasm!` and `dynasm_backwards!` macros. Any directives used in these macro invocations are normally local to the invocation itself, unless the `filelocal` crate feature is used. This feature requires a nightly compiler. Additionally, the `dynasm_opmap` and `dynasm_extract` development features can be used to export two additional macros with matching names. These macros expand into instruction listing overviews and are normally only used for documentation purposes.
