2012-06-25fix arm crti/crtn codeRich Felker-0/+2
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).
2012-02-06add support for init/finit (constructors and destructors)Rich Felker-0/+9
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.
