most dictionary functions (but not yet iterator protocol). * yasm.pyx: Add Py_INCREF, Py_DECREF, malloc, free externals. * coretype.pxi: Rename c_print to print_, add some missing yasm_expr_op enum values. svn path=/trunk/yasm/; revision=1491

"""Interface to the Yasm library.
|
|
|
|
The Yasm library (aka libyasm) provides the core functionality of the Yasm
|
|
assembler. Classes in this library provide for manipulation of machine
|
|
instructions and object file constructs such as symbol tables and sections.
|
|
|
|
Expression objects encapsulate complex expressions containing registers,
|
|
symbols, and operations such as SEG.
|
|
|
|
Bytecode objects encapsulate data or code objects such as data, reserve,
|
|
align, or instructions.
|
|
|
|
Section objects encapsulate an object file section, including the section
|
|
name, any Bytecode objects contained within that section, and other
|
|
information.
