-Initializer rewrite:
-- determining of array size for array types of unspecified length is wrong in
- presence of designators and unions
-
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
+- create structures for variables and functions, removing the omnipotent
+ declaration
Lexer:
-- Add preprocessor code
+- 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:
-- the expect macros abort functions directly. This leads to some functions
- 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
+- 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
-- 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
+- for errors relating to function argument, print number of argument
+- print initialisation type_path for initializer errors
ast2firm:
- handle non-constant initializers
-- output source file positions for panics...
+- 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:
Missing Warnings:
-* dead assignments (int x = 5; x = bla(); -> dead assignment at x = 5;)
-* unused label
-*
+- 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
