tinycc/TODO

TODO list:

- finish varargs.h support
- add alloca()
- fix static functions declared inside block
- fix bitfield binary operations
- C99: add variable size arrays
- C99: add complex types
- GCC: add statment expressions
- ignore __extension__ keyword (see 20010328-1.c). 
- Add __restrict keyword (20010611-1.c).
- postfix compound literals (see 20010124-1.c)
- handle '? x, y : z' in reversed function arguments or unsized
  variable initialization (',' is considered incorrectly as separator
  in preparser) : use a "record" parse mode ?
- fix multiple unions init
- test includes in libtcc_test.
- look at GCC 3.2 compatibility problems.
- add option for auto run
- implement minimal 'asm' extension
- setjmp is not supported properly in bound checking.
- better local variables handling (needed for other targets)
- fix bound check code with '&' on local variables (currently done
  only for local arrays).
- sizeof, alignof, typeof can still generate code in some cases.
- bound checking and float/long long/struct copy code. bound
  checking and symbol + offset optimization
- Fix the remaining libtcc memory leaks.
- make libtcc fully reentrant (except for the compilation stage itself).
- '-MD' option

Optimizations:

- suppress specific anonymous symbol handling
- more parse optimizations (=even faster compilation)
- memory alloc optimizations (=even faster compilation)

Not critical:

- C99: fix multiple compound literals inits in blocks (ISOC99
  normative example - only relevant when using gotos! -> must add
  boolean variable to tell if compound literal was already
  initialized).
- add PowerPC or ARM code generator and improve codegen for RISC (need
  to suppress VT_LOCAL and use a base register instead).
- interactive mode / integrated debugger
- fix preprocessor symbol redefinition
- better constant opt (&&, ||, ?:)
- add portable byte code generator and interpreter for other
  unsupported architectures.
- C++: variable declaration in for, minimal 'class' support.
- win32: add __stdcall, __intxx. use resolve for bchecked malloc et
  al. check GetModuleHandle for dlls. check exception code (exception
  filter func).
- handle void (__attribute__() *ptr)()
