Before Release
~~~~~~~~~~~~~~
* Add a c.MCFLAGS which seperates machine flags -mXXX and -fXXX into
MCFLAGS and the rest into CFLAGS so machine code can be built
(eg, bootloader). RTEMS build would merge both, rtems-config will offer
them seperately if requested.
Configure
~~~~~~~~~
* SIZEOF_MODE_T, SIZEOF_VOID_P, BLKSIZE_T... need to be dynamically
calculated in py/waf/configure.py
* Better warnings if an option or section is missing in config.cfg after
updating when a new option has been added and 'waf config' has not been
run.
General
~~~~~
* Documentation
* Install mode (It can be used in-place w/out installing using rtems-config)
* Distribution (creating a tarball)
* Test runner
* Create a system to force options on/off/unavailable/make them required in a bsp-specific way
* Board targets so you can do waf config --board <name> and have it setup everything
Optimisations
~~~~~~~~~~~~~
* Usage of ctx.srcnode.abspath() and others should result in one call, eg.
srcnode = ctx.srcnode.abspath() at the top then "%s" % srcnode.
* No BSP should take longer than 30s to build with maximum tests enabled.
* Profile waf when the build is running
Options
~~~~~~~
* LDFLAGS is LINKERFLAGS, make sure this is changed everywhere.
CCJ - not sure which direction to make the change so made it
LINKFLAGS -> LDFLAGS.
* LIBS may be the wrong variable name to use it is not waf-eqsue.
* Changed the default for the i386/pc586 bsp adding BSP_PRESS_KEY_FOR_RESET.
Did the config, configure, build and build tests and the setting
was not picked up. Changed the default networking setting and waf
rebuilt lots of files and then the bsp reset worked.
* Classes allow duplicate options -- this needs to throw an error to avoid
typos in the case two similar options, eg INTERFACE_TX, INTERFACE_RX.
Future
~~~~~~
* Support for building multiple branches at once
- Make previous branches use versioned build directories build-5.1, build-5.2
Includes
~~~~~~~~
* cache_.h
* Look at c/wscript_arm -> arm/realview_pbx_a9_qemu.
Other BSPs need to be fixed for cache_manager.c and console*, other bsps have been
hacked to include src_include_libcpu and src_include_bsp for all files this is wrong.
Enhancements
~~~~~~~~~~~~
* Seperate logic to convert from string to internal python values in config/options.py
Config
~~~~~~
* --path-tools= cannot be relative otherwise GCC cannot find its header files it must be absolute.
* Force re-gen of config.cfg if options change in the BSP config. "NoOptionError: No option 'bsp_verbose_fatal_extension' in section: 'sparc'"
