ba562931eb This version of __diagssert13 is dead. 2012-03-16 11:44:54 +00:00

749108f9b9 Add __diagassert13() so that if libc is compiled with _DIAGNOSTIC, it does 
not end up bringing in all of stdio.
XXX: This is temporary.

8ae54e9304 Mark _rtld_debug_state as not to be inlined. Add an explicit instruction 
barrier to prevent removal of calls to it.

52a4c27e3e Add _dlauxinfo helper function to provide access to the ELF auxilary 
vector. This can normally be found via __ps_strings, but libc is
initialised too early when linked dynamically and doesn't have access to
it yet, so provide an alternative mechanism via ld.elf_so.
Bump libc minor.

e86a1635be Align in the stack before calling _rtld in the way the x86_64 ABI 
specifies. This is necessary to ensure that init functions are always
called with the correct alignment, e.g. in case they use SSE
instructions.

d7bbed6455 avoid linker warnings with the new binutils by not forcing ld.elf_so 
to be soft-float.  the floating-point usage in ld.elf_so is only
because of stdarg functions like printf(), and gcc 4.5 is good
about not actually executing the FP instructions in such functions
unless FP values are passed to them, which ld.elf_so doesn't do.

1f1b5ad097 Don't block SIGTRAP so that on architectures where the debugger needs to 
be able to receive sigtrap for breakpoints to work, it can. For example
we are setting breakpoints inside dlopen(), after we've blocked the signal,
so the process keep trapping and looping over the trap instruction without
being able to send the signal. Another way would be to move the
_rtld_debug_state() calls outside the critical section...

4a9d1308c3 obsolete libgcc_pic and friends. all libgcc's are supposed to be pic 
for platforms with shlibs already (and are.)

this obsoletes our hacks for the libgcc specs to use libgcc_pic, and
fixes a couple of other issues reported to me directly.

14d704c9e9 Add a workaround for older crt0.o that overwrite r2 (tcb pointer). 
(save tcb pointer using _lwp_setprivate in ld.elf_so and retrieve the tcb
via _lwp_getprivate in libc and use it to restore the value in r2).

e49f915c10 Refine locking scheme around init/fini to not hold the exclusive lock. 
Use a simple generation count instead and restart looking for work if it
changed (e.g. due to an dlopen call from an init function).
Leave the possible dlclose() race for now.
