2007-11-22Ignore entries of "-1" in rofixup; the linker sometimes has no choice but toBernd Schmidt
create these for deleted entries in .eh_frame.
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.
2007-11-22Certain configure scripts test for presence of dlfcn.h. Don't install itBernd Schmidt
if !HAVE_SHARED.
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

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>

2007-10-13- use the compiler-driver instead of the linkerBernhard Reutner-Fischer
- 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,")

This wants a stub_enosys(readahead) line later on, like many, many others need..
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.

I got the library to compile with the attached patches, though dynamic loader crashes early. In buildroot I changed the architecture name by hand from sparc to sparc64, otherwise the compiler produced 32-bit files with V9 (64-bit) instructions. This configuration is not supported by QEMU, so I aimed for pure 64-bit. I think Sparc64 option needs to be added to buildroot. The _Qp_ ops seem to be required by the ABI. This and setjmp patches are just hacks to get the compilation further. The _Qp_ ops can be found in glibc, would it be OK to use those? V9 assembler requires declarations for global register use. The mem* functions in sparc32 directory did not work. They are actually used only by the hybrid 32-bit + V9 CPU configuration.
