2014-02-10Use glibc_likely instead __builtin_expect.Ondřej Bílka
2014-01-01Update copyright notices with scripts/update-copyrightsAllan McRae
2013-11-21Don't use broken DL_AUTO_FUNCTION_ADDRESS()Guy Martin
On hppa and ia64, the macro DL_AUTO_FUNCTION_ADDRESS() uses the variable fptr[2] in it's own scope. The content of fptr[] is thus undefined right after the macro exits. Newer gcc's (>= 4.7) reuse the stack space of this variable triggering a segmentation fault in dl-init.c:69. To fix this we rewrite the macros to make the call directly to init and fini without needing to pass back a constructed function pointer.
2013-05-29Avoid crashing in LD_DEBUG when program name is unavailableSiddhesh Poyarekar
Resolves: #15465 The program name may be unavailable if the user application tampers with argc and argv[]. Some parts of the dynamic linker caters for this while others don't, so this patch consolidates the check and fallback into a single macro and updates all users.
