6 daysnp: Remove deprecated ast_root fieldIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
6 daysnp: symbol: Introduce symbol table + symbol cacheIan Moffett
This commit introduces a way to allocate and store symbols as structures consiting of a name and an address. We also provide a way to cache lookups to provide faster access. Signed-off-by: Ian Moffett <ian@osmora.org>
6 daysnp: lex: Introduce string tokensIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
6 dayskern: np: Add support for return statementsIan Moffett
This commit introduces lexical, parsing and code generation support for the return statements. As of now, one is only able to return unsigned integers but this will be expanded upon in the future Signed-off-by: Ian Moffett <ian@osmora.org>

6 daysnp: codegen: Deprecate AST in favor of stackgenIan Moffett
Deprecate the usage of abstract syntax treats in favor of the much saner stack machines + IR usage Signed-off-by: Ian Moffett <ian@osmora.org>
6 daysnp: codegen: Implement initial stack based codegenIan Moffett
This commit introduces the groundwork for the AMD64 PIIR backend. We will not follow through with the plans of using abstract syntax trees as they'll overly complicate the project. Instead we'll utilize a ring buffer to store the list of instructions and a stack machine for the IR code. Signed-off-by: Ian Moffett <ian@osmora.org>
