We can't use trapa #0xff on sh2, the only permissible trapa ranges are 32 to 63. On SH-2, we use trapa32 to issue a break in the same way that trapa #0xff is used on SH-3/4. This behavior is implementation specific, but is what is used in sh-ipl+g, linux, eCos, uITRON, etc. so we follow suit here.
2004-02-11New stdio core. Should be more maintainable. Fixes a couple of bugs.Manuel Novoa III
Codepaths streamlined. Improved performance for nonthreaded apps when linked with a thread-enabled libc. Minor iconv bug and some locale/thread related startup issues fixed. These showed up in getting a gcj-compiled java helloworld app running. Removed some old extension functions... _stdio_fdout and _stdio_fsfopen.

2003-12-30Rework malloc. The new default implementation is based on dlmalloc from DougEric Andersen
Lea. It is about 2x faster than the old malloc-930716, and behave itself much better -- it will properly release memory back to the system, and it uses a combination of brk() for small allocations and mmap() for larger allocations. -Erik
2003-12-30Update and restore malloc-simple. Slow as molasses, but triviallyEric Andersen
simple and releases memory immediately when asked to do so. -Erik
2003-12-27Handle the app_fini stuff in exit without requiring atexit().Manuel Novoa III
This avoids pulling in all the malloc/free code for a simple true/false app.
2003-12-27Fix a long-standing bug with pthreads. A couple of linuxthreads filesManuel Novoa III
were including libc-lock.h which had a bunch of weak pragmas. Also, uClibc supplied a number of no-op weak thread functions even though many weren't needed. This combined result was that sometimes the functional versions of thread functions in pthread would not override the weaks in libc. While fixing this, I also prepended double-underscore to all necessary weak thread funcs in uClibc, and removed all unused weaks. I did a test build, but haven't tested this since these changes are a backport from my working tree. I did test the changes there and no longer need to explicitly add -lpthread in the perl build for perl to pass its thread self tests.

2003-09-06Fix errno values. Fix MALLOC_GLIBC_COMPAT handling in malloc/malloc.c,Eric Andersen
which was reversed. Provide more consistancy between implementations. Handle it when people do stupid things like malloc(-1);

all the other *48 random functions.
2003-08-24Fix a few bugs in the new extended locale functions.Manuel Novoa III
Move stub gettext functions to a stub libintl to make switching in gnu gettext easier. Also add a few gnu-isms. Change to using hidden names with global weak aliases for the extended locale functions, as expected by libstd++. Slightly rework the locale data generation stuff to allow pregenerated locale data to be used with buildroot.
2003-08-08Add in a MALLOC_GLIBC_COMPAT option to let people decide if theyEric Andersen
want glibc style malloc(0) behavior
2003-08-01Add a new *scanf implementation, includeing the *wscanf functions.Manuel Novoa III
Should be standards compliant and with several optional features, including support for hexadecimal float notation, locale awareness, glibc-like locale-specific digit grouping with the `'' flag, and positional arg support. I tested it pretty well (finding several bugs in glibc's scanf in the process), but it is brand new so be aware. The *wprintf functions now support floating point output. Also, a couple of bugs were squashed. Finally, %a/%A conversions are now implemented. Implement the glibc xlocale interface for thread-specific locale support. Also add the various *_l(args, locale_t loc_arg) funcs. NOTE!!! setlocale() is NOT threadsafe! NOTE!!! The strto{floating point} conversion functions are now locale aware. The also now support hexadecimal floating point notation. Add the wcsto{floating point} conversion functions. Fix a bug in mktime() related to dst. Note that unlike glibc's mktime, uClibc's version always normalizes the struct tm before attempting to determine the correct dst setting if tm_isdst == -1 on entry. Add a stub version of the libintl functions. (untested) Fixed a known memory leak in setlocale() related to the collation data. Add lots of new config options (which Erik agreed to sort out :-), including finally exposing some of the stripped down stdio configs. Be careful with those though, as they haven't been tested in a long time. (temporary) GOTCHAs... The ctype functions are currently incorrect for 8-bit locales. They will be fixed shortly. The ctype functions are now table-based, resulting in larger staticly linked binaries. I'll be adding an option to use the old approach in the stub locale configuration.
2003-04-23Thierry De Corte notices that when UCLIBC_HAS_FLOAT is disabled, we must alsoEric Andersen
disable drand48, drand48_r, erand48, and erand48_r since they use floats.

2002-11-22Ok... here's the summary:Manuel Novoa III
Hopefully locale support will build when cross compiling now. Collation is still not supported, but that's what I'm currently working on. In the next couple of days, I'll probably put up a couple of files for download that will save people the trouble of generating all the glibc locales. Added *wprintf functions, although they currently don't support floating point. That will be fixed when I rewrite _dtostr... or possibly before. Added the wcsto{inttype} functions. Added iconv() and a mini iconv utility. The require locale support and only provide for conversions involving the various unicode encodings { UCS-4*, UCS-2*, UTF-32*, UTF-16*, UTF-8 }, the 8-bit codesets built with the locale data, and the internal WCHAR_T.

2002-10-31Ok, this commit is _huge_ and its gonna change the world. I'veEric Andersen
been working on a new config system on and off for about 6 months now, but I've never been fully satisfied. Well, I'm finally am happy with the new config system, so here it is. This completely removes the old uClibc configuration system, and replaces it with an entirely new system based on LinuxKernelConf, from http://www.xs4all.nl/~zippel/lc/ As it turns out, Linus has just merged LinuxKernelConf into Linux 2.5.45, so it looks like I made the right choice. I have thus far updated only x86. I'll be updating the other architectures shortly. -Erik

2002-10-09* Add support for uClinux's broken munmap, contingent onMiles Bader
__UCLIBC_UCLINUX_BROKEN_MUNMAP__ (which is currently not defined anywhere). This makes other cases a tiny bit less efficient too. * Move the malloc lock into the heap structure (locking is still done at the malloc level though, not by the heap functions). * Initialize the malloc heap to contain a tiny initial static free-area so that programs that only do a very little allocation won't ever call mmap.
2002-09-26A bug fix from Alexey V. Neyman:Eric Andersen
In case of vfork(), the parent was left with __exit_count of -1 and thus tried to find non-NULL value of __exit_function_table[-1].atexit, __exit_function_table[-2].atexit and call this function; of course, it leads to coredump.
