ArmAsm
Raw Normal View History

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.

.global _init
_init:
align stack properly for calling global ctors/dtors on x86[_64] failure to do so was causing crashes on x86_64 when ctors used SSE, which was first observed when ctors called variadic functions due to the SSE prologue code inserted into every variadic function.
