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. 2012-02-06 19:39:09 +00:00			`.section .init`

add function types to arm crt assembly 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. 2013-08-15 18:52:27 +00:00			`.type _init,%function`

remove init/fini array asm from arm crti/crtn files this code has been replaced by portable C code that works on all archs.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. 2013-07-21 07:48:35 +00:00			`push {r0,lr}`
