2007-12-03Blackfin FD-PIC patch 2/6.Bernd Schmidt
Add the necessary changes in ld.so and libdl to deal with targets that prepend an underscore to symbol names.
2007-12-03Blackfin FD-PIC patch 1/6.Bernd Schmidt
Add a new function _dl_free. In _dl_malloc, ensure we always get back a full page from mmap. Reset _dl_malloc_function and _dl_free_function when libdl is initialized.
2007-12-03Some versions of gcc consider inline merely a hint. AVR32 depends on theCarmelo Amoroso
system calls actually being inlined, so AVR32 needs to use __always_inline instead of just inline. The attached patch changes this for the system calls. Signed-off-by: Hans-Christian Egtvedt <hcegtvedt@atmel.com>
2007-12-03realpath: reduce stack usage from 3*PATH_MAX (12k) to 1*PATH_MAX (4k).Denis Vlasenko
reduction is achieved by direct use of user-supplied PATH_MAX sized buffer for result (without intermediate copy) and changes in copy_buf[] usage - now it is used for both "source" pathname and link name (it works because they have to be less than PATH_MAX combined, otherwise we return NULL).

2007-11-23Some shared flat improvements.Bernd Schmidt
Fix minor errors: - UCLIBC_SHARED_FLAT_ID instead of SHARED_FLAT_ID - use -Wl,-shared-lib-id properly Use libc_so.a as the source for the shared libc, in order to be able to use -mleaf-id-shared-library on the Blackfin.

2007-11-22Add Blackfin specific mmap implementation using sys_mmap2.Bernd Schmidt
2007-11-22sys/procfs.h defines a typedef for floating point registers that references anBernd Schmidt
undefined structure. This typedef is used in linuxthreads.old-db, causing a compilation failure. Fixed by defining an empty structure for it - we don't have fp regs anyway.

2007-11-22Add hidden symbols for a number of pthread functions, and use them to ensureBernd Schmidt
that all entries in the __pthread_functions point to functions within libpthread, not identically-named functions in libc.

2007-11-20ARM SHMLBA = (4 * PAGE_SIZE). Currently in uclibc arm used shm.h fromCarmelo Amoroso
common directory where SHMLBA = __getpagesize() This patch fixes the issue. Khem Raj MontaVista Software Inc.
2007-11-16If uClibc's ld.so encounters text relocations in a shared library - one Carmelo Amoroso
containing an object built without -fpic/-fPIC - then: * If __FORCE_SHAREABLE_TEXT_SEGMENTS__, then it gives an error "Can't modify %s's text section. Use GCC option -fPIC for shared objects, please.\n" and exits. * Otherwise, it makes the library's pages writable and relocates it. If it encounters text relocations in a position-independent executable - one containing an object built without -fpie/-fPIE/-fpic/-fPIC - then: * If __FORCE_SHAREABLE_TEXT_SEGMENTS__, it does nothing about making the pages writable, leading to a crash. * Otherwise, the loop to make the pages writable uses the same variable ppnt as used in an outer loop, messing up that outer loop and also causing a crash. This patch fixes both cases, by giving an error if __FORCE_SHAREABLE_TEXT_SEGMENTS__ and saving and restoring ppnt otherwise. Tested in both cases on ARM EABI. Joseph S. Myers joseph@codesourcery.com

2007-10-24- fix order of link-flagsBernhard Reutner-Fischer
On cygwin one has to pass make menuconfig HOST_LOADLIBES="-lcurses -lintl" otherwise just curses is linked in and some symbols that live in intl are unresolved. Closes #1554 and possibly a couple of other reports.
2007-10-23Poll with zero timeoutJoakim Tjernlund
Jean-Christian de Rivaz writes: The attached patch solve an issue I faced while using the libdbus-glib waiting for a D-Bus message or the end of a glib timer at the same time. This specific case of use generate a poll call with a zero timeout. On platformes with the glibc a zero timeout poll return immetiately even if there is no file descriptor event. But on platformes with uClibc a zero timeout poll block until a file descriptor event occurs.
2007-10-21Handle STT_COMMON symbols too. Following binutils releaseJoakim Tjernlund
will set the type of common symbols to STT_COMMON instead of STT_OBJECTS, so the dynamic linker needs to handle this type os symbols too. Same changes have been added to glibc (See: bugzilla #5104). This patch ensures the uclibc will work with later bintuils. Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>

- adjust setting flags accordingly to use (hardcoded, see below) -Wl, Potential improvements: *) --warn-unresolved-symbols should perhaps be used for all libs *) eventually rename LDFLAGS to CC_LDFLAGS *) probe for compiler driver's notion of flag to use for passing in linker flags (i.e. don't hardcode "-Wl,")

2007-09-28This patch will fix a problem when the same host is defined with both IPv4 andMike Frysinger
IPv6 entries in /etc/hosts. Previous only the first of these host would work, as uClibc would read the /etc/hosts file from top to bottom, failing if the first hit did not match the IP type. Now uClibc will continue reading, even if the first correct entry name, but wrong IP type fails. Thus, allowing a second correct entry name with correct IP type will result in a name resolve.

GCC 4.3 will put fixed headers in a seperate include-fixed directory. And I don't think that there are people who are still using the 'stupid' GCC which cannot handle -iwithprefix, at least it works with gcc-3.3.x.
