2012-07-02fix sigsetjmp on arm (needs asm)Rich Felker1-0/+13
no idea why gcc refuses to compile the C code to use a tail call, but it's best to use asm anyway so we don't have to rely on the quality of the compiler's optimizations for correct code.
2011-09-18initial commit of the arm portRich Felker1-0/+11
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.
