2008-04-16Fix whitespace damage in AVR32 part of ldso.Hans-Christian Egtvedt

The attached patch adds support for compiling arm uClibc as pure Thumb code. This is needed because some recent ARM codes do not implement traditional ARM mode. Specifically: * Cortex-M1 - An extremely minimal FPGA based core that only implements Thumb-1 (aka ARMv6-M). * Cortex-M3 - A Thumb-2 only ARMv7-M core. Most of uClibc already builds in Thumb mode, all that is left are a handful of assembly bits. Tested on arm-uclinuxeabi.

While compiling trunk on ARM with GCC 4.2 and enabling LDSO_GNU_HASH_SUPPORT I stumbled upon this problem. GCC made a call to libgcc function __aeabi_uidivmod()->__div0()->__raise() and raise is not yet compiled in at the time of compiling ldso so I got well known undefined symbol __raise problem This patch uses the do_rem () macro to do the same operation.

The following patches add support for the Xtensa processor architecture to uClibc. They are based on a recent SVN checkout (12/05/2007). The first patch (attached to this post) adds Xtensa support to various shared configuration and make files. The following patches then include the Xtensa specific files and directories. I welcome any feedback and would appreciate it if you could include the patches into the mainline tree. I am certainly committed to maintain the port. Bob Wilson was kind enough to review the patches. Some notes about the architecture: Xtensa is a configurable and extensible processor architecture developed by Tensilica. For more information, please visit: www.linux-xtensa.org.

2007-12-04Blackfin FD-PIC patch 6/6.Bernd Schmidt
These are mostly the changes necessary to deal with loading the libraries into memory. A couple new target macros are defined for this purpose, and the code in dl-elf.c is modified to deal with nommu systems.
2007-12-03Fix a few warnings introduced by my previous commits.Bernd Schmidt
2007-12-03Blackfin FD-PIC patches 5/6.Bernd Schmidt
A couple more target macros for ld.so to deal with FD-PIC support. We need special code to compute the initial got and dpnt, and we need to pass extra arguments to _dl_get_ready_to_run.
2007-12-03Blackfin FD-PIC patch 4/6.Bernd Schmidt
Add a hash table for function descriptors on FD-PIC targets.
2007-12-03Blackfin FD-PIC patch 3/6.Bernd Schmidt
Change _dl_find_hash to _dl_lookup_hash, as on the NPTL branch. _dl_find_hash is now a wrapper function around it; unlike on the NPTL branch, it retains the old interface so that not all callers need to be changed. _dl_lookup_hash can optionally give its caller a pointer to the module where the symbol was found. Introduce ELF_RTYPE_CLASS_DLSYM for lookups from libdl. Spelling fixes in the Blackfin port, since Alex Oliva's original version of these patches used _dl_find_hash_mod as the name of the function rather than _dl_lookup_hash.
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>

2007-11-16If 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

2007-10-21Handle 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).

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.
