Rich Felker	d432b2c057	fix regression that made shared libs crash on arm	13 years ago
Rich Felker	34aa169dcf	add support for ctors/dtors on arm with modern gcc a while back, gcc switched from using the old _init/_fini fragments method for calling ctors and dtors on arm to the __init_array and __fini_array method. unfortunately, on glibc this depends on ugly hacks involving making libc.so a linker script and pulling parts of libc into the main program binary. so I cheat a little bit, and just write asm to iterate over the init/fini arrays from the _init/_fini asm. the same approach could be used on any arch it's needed on, but for now arm is the only one.	14 years ago
Rich Felker	9abab94b21	fix arm crti/crtn code lr must be saved because init/fini-section code from the compiler clobbers it. this was not a problem when i tested without gcc's crtbegin/crtend files present, but with them, musl on arm fails to work (infinite loop in _init).	14 years ago
Rich Felker	4ce3cb5cdd	add support for init/finit (constructors and destructors) this is mainly in hopes of supporting c++ (not yet possible for other reasons) but will also help applications/libraries which use (and more often, abuse) the gcc __attribute__((__constructor__)) feature in "C" code. x86_64 and arm versions of the new startup asm are untested and may have minor problems.	14 years ago
