This project provides framework to parse assembly files into AST-like structures. It was written as a replacement for KernelCare and LibCare hand-written parsers to allow for easier extensibility.
Since we are only interested in comparing symbol definitions we are not into correct parsing of the assembly. This is somehow lightweight implementation that only cares about directives leaving all the tokens/commands on their own except for interesting ones.
I link all the tokens at the creation time and reuse these lists later to link tokens into the statements. But, since flex/bison uses lookahead tokens sometimes and not another I have to check that I don't add lookahead tokens to the statements.
All the statements are linked into document on the creation time so I should only use left-side recursion on statements token.
