Rich Felker	6fef8cafbd	remove hand-written crt1.s and Scrt1.s files for all archs since commit `c5e34dabbb`, crt1.c has provided a "mostly-C" implementation of the crt1 start file that avoids the need for arch-specific symbol referencing, PIC/PIE-specific code variants, etc. but for archs that had existing hand-written versions, the new code was initially unused, and later only used as the dynamic linker entry point. this commit switches all archs to using the new code. the code being removed was a recurring source of subtle errors, and was still broken at least on arm, where it failed to properly align the stack pointer before calling into C code.	11 years ago
Rich Felker	a6d272127b	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.	13 years ago
Rich Felker	2be87702b7	remove some junk from x86_64 start files looks like nik copied these "extra arguments" from the i386 code. they're not actually arguments there, just 1-byte instructions to make sure the stack is aligned to 16 bytes after all the other arguments are pushed. since each push is 8 bytes on x86_64, they happened to have no effect here, but their presence is confusing and a minor waste of space.	14 years ago
Rich Felker	94167cafd5	PIE support for x86_64 (untested)	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
