* ldso: clean up breakage in tls mergeMike Frysinger2009-10-1614-159/+137
| | | | | | | | | | | 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> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>

* Blackfin: rename __dl_boot to __startMike Frysinger2009-08-192-11/+8
| | | | | | | | | | | | | | The entry symbol is __start rather than __dl_boot. While in the past this was silently ignored, now with common code checking the _start symbol in C code, we end up with link errors: ldso/ldso/ld-uClibc_so.a(ldso.oS): In function `__dl_get_ready_to_run': ldso/ldso/ldso.c:(.text+0x2b30): undefined reference to `__start' collect2: ld returned 1 exit status make[1]: *** [lib/ld-uClibc.so] Error 1 Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
* Blackfin: fix incorrect attribute orderMike Frysinger2009-08-191-1/+2
| | | | | | | | | | | | | | | | | | The order of attributes in a function definition matters and in a few places in the Blackfin code, it was being applied to the return type instead of the function itself.

* Blackfin: add elf_machine_load_address() stubMike Frysinger2009-08-191-0/+8
| | | | | | | | | | | | The Blackfin port never defined elf_machine_load_address() because the one place this code is called never matters to us. But without it, common code likes to hit a build failure, so stub it out. ldso/ldso/dl-startup.c: In function '_dl_start': ldso/ldso/dl-startup.c:170: warning: implicit declaration of function 'elf_machine_load_address' Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
* ldso: fix building for FDPIC systemsMike Frysinger2009-08-191-1/+1
| | | | | | | | | | | The force shareable code missed a spot of using the DL_RELOC_ADDR() indirection thus leading to invalid operands: ldso/ldso/ldso.c: In function '_dl_get_ready_to_run': ldso/ldso/ldso.c:409: error: invalid operands to binary + (have 'Elf32_Addr' and 'struct elf32_fdpic_loadaddr') Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>

Disable mmap2() if we're compiling for coldfire and fall back to mmap(). It seems to map a different file area on a 2.6.25 linux kernel. 2. Uses pc-relative addresing[1], computes ADDR_ALIGN, PAGE_ALIGN and OFFSET_ALIGN relatively to _dl_pagesize[3]. On coldfire/M5485 _dl_pagesize is 0x2000.

| | | | | | | | | * pulled updated asm and headers from glibc for sparc32 * probably no cancellation support yet * no shared TLS relocs yet, since ldso is hosed on sparc still note: didn't use TARGET_SUBARCH method of includes since that would cause other parts of libc to fail currently.
