%description
9cc is a successor of the 8cc C compiler. It's written in such a way to
be easily understood while generating reasonably efficient assembly.

9cc has more stages than 8cc. Here is an overview of the internals:

 * Compiles an input string to abstract syntax trees.
 * Runs a semantic analyzer on the trees to add a type to each tree node.
 * Converts the trees to intermediate code (IR), which in some degree
   resembles x86-64 instructions but has an infinite number of registers.
 * Maps an infinite number of registers to a finite number of registers.
 * Generates x86-64 instructions from the IR.
