Refactoring:
- create an empty_statement_t and use that instead of a NULL pointer in places
like if, loop bodys, statements after labels
+- eliminate target_architecture.h and replace with stuff in lang_features.h
+- redo storage classes: so we can separate real from declared storage class
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 sturct/union members
- the expect macros abort functions directly. This leads to some functions
- not resetting the current context properly (parse_for)
+ not resetting the current context properly (parse_for); expect in expressions
+ suddenly return NULL which triggers asserts
- label: declaration; is no valid C99 but we parse it anyway
-- designator support for initializers
-- add constant folding code
-- Refactor code, so code to handle number values and strings is
- an own module and replacable
+- 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
- Support some attributes. noreturn, unused, printf, scanf, packed would be
interesting candidates
+- Add columns to source positions
+- SourcePositions could be stored selectively on expressions that really need
+ them.
+- check semantic for functions declared/defined in global scope and declared
+ again in a local scope
+- print initialisation type_path for initializer errors
ast2firm:
+- handle non-constant initializers
- output source file positions for panics...
-- output variable names for uninitialized variable warnings
+- handle bitfield members with 0 correctly (standard says they finish the
+ current unit)
Missing Warnings:
* dead assignments (int x = 5; x = bla(); -> dead assignment at x = 5;)
