2021-02-17treewide: rewrite ucode interpreterJo-Philipp Wich
Replace the former AST walking interpreter implementation with a single pass bytecode compiler and a corresponding virtual machine. The rewrite lays the groundwork for a couple of improvements with will be subsequently implemented: - Ability to precompile ucode sources into binary byte code - Strippable debug information - Reduced runtime memory usage Signed-off-by: Jo-Philipp Wich <jo@mein.io>

2020-11-15lexer: improve scanner performanceJo-Philipp Wich
Optimize the strncmp() based token lookup with an integer comparison approach which roughly cuts the time of the source code parsing phase in half. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-10-14treewide: unify error handlingJo-Philipp Wich
Get rid of the distinction between lexer/parser errors and runtime exceptions, use exceptions everywhere instead. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-10-14treewide: rework source file and callstack handlingJo-Philipp Wich
- Keep an open FILE* reference to processed source files in order to be able to rewind and extract error context later - Build a proper call stack when invoking utpl functions - Report call stack in exceptions Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-09-06treewide: refactor internal AST structuresJo-Philipp Wich
- unify operand and value tag structures - use a contiguous array for storing opcodes - use relative offsets for next and children ops - defer function creation to runtime - rework "this" context handling by storing context pointer in scope tags Signed-off-by: Jo-Philipp Wich <jo@mein.io>
