2009-12-17check if USE_TLS is defined before useHans-Christian Egtvedt
This patch will convert all the #ifdef USE_TLS and #if USE_TLS to #if defined(USE_TLS) && USE_TLS. By checking if the USE_TLS is defined before checking its value will result in correct behavior for architectures not defining this config symbol.

2009-10-15ldso: clean up breakage in tls mergeMike Frysinger
The TLS merge 534661b91c9849 introduced multiple style problems as well as random breakage: - missing _dl_free - incomplete parametrization of _dl_lookup_hash - restore FDPIC handling in _dl_lookup_hash Signed-off-by: Mike Frysinger <vapier@gentoo.org>

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.

2006-11-17Bernd Schmidt writes:Mike Frysinger
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.
2006-10-07Bernd Schmidt writes:Mike Frysinger
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.

execution of ldso. Added new asm for MIPS to be tested. All arches should retest.
2005-03-14Generalize optimized relative reloc procesing.Joakim Tjernlund
Add elf_machine_dynamic() and elf_machine_load_address() for all archs. elf_machine_dynamic() replaces the #ifdef mess to get at the GOT. elf_machine_load_address() is needed to execute ldso directly, this is not complete yet. I probably broke one or two archs(only tested PPC) so please try and report problems. For a report to be useful you need to enable __SUPPORT_LD_DEBUG_EARLY__ and __SUPPORT_LD_DEBUG__

2004-11-02- Remove dynamic_size from struct elf_resolve.Joakim Tjernlund
- Replace all open coded dynamic handling with a function. Reduces size. - Fold special MIPS dynamic code into the dynamic_info item. - Add RELRO support. - Support linking with "-z now". - prepare for DT_RELACOUNT/DT_RELCOUNT optimization. - Add -z now to ld.so linking, this is what ld.so does anyway so let the linker know that.
