| | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | Currently a static libdl.a doesn't run all the constructors or destructors of the libraries it loads. I can't see a good reason for that, and it does cause aborts in the destructors it does run for things like libgcc.so on the Blackfin. Fixed with the patch below - untested in mainline, but the equivalent has been in our Blackfin tree for a while now.

| | | | | | | | I experiencied some problems while trying to debug the ld.so (sh4) in debug mode. I found that the _start code was not placed into any PT_LOAD segment causing a SIGSEV. I solved this issue explicitely placing the _start code into the .text section (see attached patch).

| | | | | | | | | Hi All, the attached patch completes my previous patch on statically linked application calling dlopen enabling the support for LD_DEBUG. Further it fixes the missing initialization of the _dl_library_path variable. This patch has been fully tested with the uClibc-nptl branch (sh4).

* Joseph S. Myers writes:Joakim Tjernlund2007-01-091-2/+2
| | | | | | | | | ELF symbol names are arbitrary 0-terminated sequences of bytes, and the ELF hash function is defined in the ELF specification to use unsigned char. Thus uClibc's _dl_elf_hash, using plain char, breaks when char is signed and symbol names contain bytes with the high bit set, as with GCC's ucnid-* tests. This patch fixes this problem.

| | | | | | | This reintroduces a mechanism identical to the DL_BOOT macro present in older versions of uClibc. On Blackfin and FRV, we want to pass more than one argument to _dl_start. We also want to do something special before returning, so delete the warning when the START macro is defined.

| | | | | | | | | | | | The patch below fixes a bug in the new ARM _ld_linux_resolve implementation. I'm don't know if/how the current implementation was tested, but it's completely broken. This patch makes the prologue and epilogue agree on how big the stack frame is, and also makes sure EABI doubleword stack alignment is preserved. Tested on arm-linux-gnueabi.
* This change reimplements the ARM _dl_linux_resolve entry point - this isEric Andersen2006-11-103-53/+192
| | | | | | | called to resolve DLL PLT entries. The assembler is changed to be thumb compatible and slightly faster, the C function, _dl_linux_resolver (note the extra r) is changed to take a byte address in place of an 8 byte count (faster in caller and callee, and slightly easier to understand).
* arm thumb:Eric Andersen2006-11-101-0/+35
| | | | | | | | | | | | | | | | | | | | | | Put the call_via_rx code into each executable - call_via_ip cannot possibly work if called through the PLT! ldso requires this code too as it is not linked with the crt stuff and thumb ldso does make calls via a register. The patch puts the code into crti.S so that it is linked into every normally built application (if thumb or interworking is selected). This is only 30 extra bytes and it works - the previous code did not because nothing both implemented and exported the APIs (they were in libgcc, but not in the version script). crti.S and crtn.S is also brought up to date with GCC 3.4.4 - this is essential for thumb support because the .init and .fini sections must use arm or thumb code to match the compilation of the libraries. Note that code which pushes stuff into .init or .fini must be compiled with or without -mthumb to match the uclibc compilation - and gcc itself (which does do this) must therefore be compiled to match.

* Bernd Schmidt writes:Mike Frysinger2006-10-072-10/+25
| | | | | | | | | | | This introduces a new SEND_EARLY_STDERR macro that is to be used in dl-startup.c before ld.so is relocated. It is needed on Blackfin (and frv) FDPIC since we have to use special tricks to get the address of a string constant. EARLY_STDERR_SPECIAL gets defined on such a machine and prevents printing of debug strings inside the loop that relocates ld.so, since we can't decide which of the two variants to use.
