-*) Check cris architecture

-Erik's TODO list for the next release:
-
- *) When options are disabled, also disable them in the
- include files as well.
- *) Make all configured out symbols optionally add a linker warning saying
- "Hey! You are trying to use a function that you have configured out.
- If you really want to use this function, enable CONFIG_FOO and rebuild
- uClibc".
+TODO list for the uClibc 1.0.0 release:
+
+ *) mjn3's mysterious python select/poll self-test failure that he
+ still needs to tell me about
+ *) Perhaps implement glibc style frame-unwinding, so that gcc need
+ not be built with --enable-sjlj-exceptions for exception handling to work.
+ *) Implement some mechanism (perhaps encoded in the .so name)
+ for flagging config options that break the ABI. Options
+ such as UCLIBC_HAS_SOFT_FLOAT, UCLIBC_HAS_THREADS, UCLIBC_HAS_LOCALE,
+ and perhaps others (finalize list) produce a lib with a differing
+ ABI. Make it so apps cannot use an ABI mis-matched uClibc.
+ *) Implement the float and long double versions of math funcs,
+ using wrappers on top of the double versions (size / precision
+ trade off).
+ *) Delete current profiling code (because it is crap
+ and only works when static + PIC)
+ *) Fix profiling by adding missing stub functions per
+ http://uclibc.org/lists/uclibc/2004-February/008167.html
+ and used by, i.e. http://www710.univ-lyon1.fr/~yperret/fnccheck/
+ *) Audit header files. Remove prototypes for all functions that
+ are not supported. Especially needed for the libm headers.
+ *) Audit header files. When options are disabled, also disable
+ them in the include files as well.
*) Make all small objects (>~50 bytes) into either inlines or
into a static library
- *) Document all differences between the feature set of uClibc
- and glibc.
+ *) Add support for Linux 2.6.x NGPL pthreads, futexes, etc
+ *) Documentation updates:
+ *) Update README document
+ *) Update INSTALL document
+ *) Update docs/Glibc_vs_uClibc_Differences.txt document
+ and fully document all differences between the feature
+ set of uClibc and glibc.
+ *) Update docs/uClibc_vs_SuSv3.txt document
+ *) Update docs/threads.txt document
+ *) Write a HOWTO document
+ *) Write man pages for ldd and ldconfig utility binaries
*) Fix regex so it isn't so stinking big
*) Fix glob so it isn't so stinking big
- *) Fix the dlopen() bug with handling of symbols that are already
- resolved. Seems if it is already resolved it ignores them rather than
- resolving the new symbol and overriding.
- *) Adapt uClibc to use Linux 2.5.x pthreads
- *) Remove all use of kernel headers (i.e. copy the needed bits
- to completely specify the per-arch kernel ABI).
- *) Fix x86 profiling. It currently only works when static + PIC...
+ *) run 'nm -D --size-sort -t d libuClibc-0.9.26.so' and work on the
+ biggest things (i.e. stuff at the end of the list) to make
+ them smaller.
+ *) Cleanup / rewrite sysconf.c. It should get some information
+ from ldso (such as HZ). Other stuff it currently just makes
+ up, which is obviously wrong. Also bits/uClibc_clk_tck.h
+ needs to be updated at the same time to get proper HZ values.
+ *) __data_start needs to be added to any crt0.S files that don't
+ currently have it. It is used by the boehm gc. mjn3 has added
+ it to i386 and mips, but some archs are still missing it.
