Refactoring:
- eliminate target_architecture.h and replace with stuff in lang_features.h
-- create structures for variables and functions, removing the omnipotent
- declaration
Lexer:
- Add preprocessor code.
-- proper handling of different file encodings, parsing non-ascii strings
- We could save some space by holding source positions in a separate (somehow
compressed table) and only storing pointers to it on the AST.
Parser:
-- disallow storage class specifiers in struct/union members
- add constant folding code (optional, ast2firm already does it)
- Refactor code, so code to handle number values (and strings?) is an own
module and replacable
- print initialisation type_path for initializer errors
ast2firm:
-- handle non-constant initializers
- output source file positions for panics.
-- handle bitfield members with 0 correctly (standard says they finish the
- current unit)
-- merge functions entities declared in lokal scope
Missing Errors:
+- goto over VLA declarations
Missing Warnings:
- dead assignments (int x = 5; x = bla(); -> dead assignment at x = 5;)
-- check switches for all enums values
-- catch the if(k = b) cases, maybe require all assignments to be in parentheses
- (but some few exceptions like toplevel, nested assignments)
main/driver:
-- delete output file if we had an error
