+Refactoring:
+- eliminate target_architecture.h and replace with stuff in lang_features.h
+
Lexer:
-- proper support of preprocessor
-- parse float numbers
-- octal&hex escape sequences
-- wide string constants
-- proper handling of different file encodings
+- 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)
-- proper handling of function pointer types
-- outermost typequalifiers can differ between function declarations and
- implementations...
-- fix semantic to ignore type qualifiers (const double is the same as double)
-- label: declaration; is no valid C99 but we parse it anyway
+- 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
+- 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:
-- output source file positions for panics...
-- correctly handle pointer ++, --
-
+- output source file positions for panics.
+- handle bitfield members with 0 correctly (standard says they finish the
+ current unit)
-Coole Warnungen:
+Missing Errors:
- int x = 5;
- x = bla():
+Missing Warnings:
+- dead assignments (int x = 5; x = bla(); -> dead assignment at x = 5;)
+- catch the if(k = b) cases, maybe require all assignments to be in parentheses
+ (but some few exceptions like toplevel, nested assignments)
- -> dead assignment
+main/driver:
+- delete output file if we had an error
