2022-01-18program: implement support for precompiling source filesJo-Philipp Wich
- Introduce new command line flags `-o` and `-O` to write compiled program code into the specified output file - Add support for transparently executing precompiled files, the lexical analyzing and com,pilation phase is skipped in this case Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2022-01-18source: refactor source file handlingJo-Philipp Wich
- Move source object pointer into program entity which is referenced by each function - Move lineinfo related routines into source.c and use them from lexer.c since lineinfo encoding does not belong into the lexical analyzer. - Implement initial infrastructure for detecting source file type, this is required later to differentiate between plaintext and precompiled bytecode files Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2022-01-18compiler, vm: use a program wide constant listJo-Philipp Wich
Instead of storing constant values per function, maintain a global program wide list for all constant values within the current compilation unit. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2022-01-18types: add initial infrastructure for function serializationJo-Philipp Wich
- Introduce a new "program" entity which holds the list of functions created during compilation - Instead of storing pointers to the in-memory function representation in the constant list, store the index of the function within the program's function list - When loading functions from the constant list, retrieve the function by index from the program entity Signed-off-by: Jo-Philipp Wich <jo@mein.io>
