2013-08-15	add function types to arm crt assembly	Rich Felker	-0/+3
	without these, calls may be resolved incorrectly if the calling code has been compiled to thumb instead of arm. it's not clear to me at this point whether crt_arch.h is even working if crt1.c is built as thumb; this needs testing. but the _init and _fini issues were known to cause crashes in static-linked apps when libc was built as thumb, and this commit should fix that issue.
2013-07-21	remove init/fini array asm from arm crti/crtn files	Rich Felker	-44/+4
	this code has been replaced by portable C code that works on all archs. the old asm needs to be removed or ctors/dtors will run twice.
2013-07-10	add PIE support for ARM	Rich Felker	-0/+30

2013-02-03	fix regression that made shared libs crash on arm	Rich Felker	-0/+4

2012-12-07	add support for ctors/dtors on arm with modern gcc	Rich Felker	-4/+40
	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.
2012-06-25	fix arm crti/crtn code	Rich Felker	-0/+4
	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).
2012-02-06	add support for init/finit (constructors and destructors)	Rich Felker	-2/+21
	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.
2011-09-18	initial commit of the arm port	Rich Felker	-0/+13
	this port assumes eabi calling conventions, eabi linux syscall convention, and presence of the kernel helpers at 0xffff0f?0 needed for threads support. otherwise it makes very few assumptions, and the code should work even on armv4 without thumb support, as well as on systems with thumb interworking. the bits headers declare this a little endian system, but as far as i can tell the code should work equally well on big endian. some small details are probably broken; so far, testing has been limited to qemu/aboriginal linux.
