====== Reminders ======

Things that might be considered to be evaluated/implemented/included...


===== Compiler =====

  * Fix standard compliance problems in the preprocessor.
  * Braces in initializers work in a non standard way, standard compliant initializer with braces are not always accepted.
  * Fix issue with ''goto'' into a block that declares a local label.
  * Make ''fastcall'' the standard.
  * [[cc65:roadmap|Floating point support]]
===== Assembler =====



===== Linker =====

  * Fix issues with o65 format.
  * Fix internal error in complex setups where the precalculated memory setup differs from the one determined later.
  * Map files do not work for o65 output in presence of external symbols. 
  * Add option to omit generation of output files if the file length is zero (useful for unused overlays).
  * Intel hex output.
  * Segment overlays.


===== Disassembler =====


===== Compile & Link Utility =====

  * Add capability to call other external programs for processing, for example Pucrunch.


===== Platform independent runtime library =====

  * Complete multiplication and division routines. Currently it's somewhat a mess.
  * The changes in the TGI library need a review and cleanup. The new vector font routines need testing, docs and maybe a sample program. Clipping is probably not implemented (needs check).
  * There's a function tgi_imulround() - declared in tgi/tgi-kernel.h - that can be used with tgi_getaspectratio() to scale a value "up" by the aspect ratio. However it is as well desirable to be able to scale "down" by the aspect ratio - maybe with a function called tgi_idivround().
  * Implement an alternative "naive" heap manager that simply increments a pointer for every allocation (and doesn't actually de-allocate anything) to allow i.e. the module loader to be used without linking in the full blown heap manager.
  * Discuss if it is desirable to have standard SER and/or EMD drivers - like the standard JOY, MOU and TGI drivers.
  * Several formats in printf are broken: ''printf("%04d",-12)'' and ''printf("%#04x",12)'' are examples.
  * Abstract printer support.
===== CBM library =====

  * Implement the DIO interface.
  * Implement a Userport SER driver based on George Hug's 'Toward 2400' source code - http://archive.org/details/transactor-magazines-v9-i03
  * Remove prepending "0:" / "1:" to POSIX filenames - http://www.cc65.org/mailarchive/2012-08/10683.html
  * Review handling of O_... flags in POSIX open().


===== C64 library =====

  * Implement OUTTEXT in the TGI driver.
  * Implement Soft-80 CONIO support as an "extra" .o file that "overrides" the cputc.o in the C library.
  * Add extra EMD and joystick drivers.


===== C128 library =====

  * If possible do that "blinding" of the keyboard scanner while any button/switch is active which was done for the C64-1351 driver for the C128-1351 driver too.
  * Implement OUTTEXT in the TGI drivers.
  * Find ways to increase the RAM size available to cc65 programs.
  * Test EM drivers with multidemo sample and fix the broken ones.


===== Apple II library =====

  * Implement lseek().
  * Update documentation to reflect the current linker configs.
  * Have the EM driver detect AUXMEM and cooperate with /RAM.
  * Implement a TGI driver that "hides" the hires screen using AUXMEM.
  * Allow _sys() to call ROM routines.
  * Add cmdline support to exec().
  * Add support for visible cursor on cgetc().


===== Atari library =====

  * Add dio_query_sectcount() to complete the DIO implementation.
    * algorithm as follows (see http://www.cc65.org/mailarchive/2012-10/10974.html):
      * Read the 4th sector. (the xf551 drive had a bug, it returned the wrong PERCOM info after reading the normally 128-byte boot sectors, a read from sector 4 eliminates this chance)
      * Read status (SIO command 0x53) and save that info.
      * Request a PERCOM block. If it succeeds use that information.
      * If reading PERCOM block fails assume 1050, 810 (or even 815) or compatible. Use the status byte 0 to differentiate between single, enhanced (medium) and double density. (bit 5 is set if double density and bit 7 is set if enhanced density). If we're only looking for sector count, only the bit 7 matters.
  * Implement the functions in device.h and test them with samples/enumdevdir.c.
  * Implement exec().
  * Add documentation for TGI and EMD drivers.
===== GEOS library =====

  * Make dio_query_sectcount() less naive.
  * Adjust the MOU driver to the current MOU kernel interface.
  * Implement the functions in device.h and test them with samples/enumdevdir.c.


===== Documentation =====

  * Update a font engine sample "tgi-preview".
===== Other stuff =====

  * Integrate Groepaz test suite and do nightly automated tests to improve the overall quality.
