5 daysnp: codegen: Support returning symbols / stringsIan Moffett
Introduce support for returning symbols or strings in memory by using the symbol table and REX prefixes for 64-bit register accesses Signed-off-by: Ian Moffett <ian@osmora.org>
5 daysnp: symbol: Ensure of assigned name and IDIan Moffett
This commit adds a lookup ID to each symbol as well as ensuring that they have a defined name even if the requested one is NULL Signed-off-by: Ian Moffett <ian@osmora.org>
5 daysnp: piir: Add bitmap based register allocationIan Moffett
Introduce register allocation via a bitmap where each bit corresponds to a specific register index. 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: piir: Annotate IR bytesIan Moffett
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>
7 dayskern: np: Add initial IR engine (PIIR)Ian Moffett
This commit introduces the initial sources for the intermediate representation (IR) engine [called PIIR (PI-IR)] to PIRHO PIIR: [NOUN]: border, boundary, frontier Signed-off-by: Ian Moffett <ian@osmora.org>
7 daysnp: parse: Create proc AST, handle end/begin, ...Ian Moffett
This commit introduces AST object types and AST integer type definitions. We also now keep track of how deep we are in begin/end tags. - Introduce parsing for TT_BEGIN - Introduce parsing for TT_END Signed-off-by: Ian Moffett <ian@osmora.org>
