Rich Felker	54c567649e	fix arm syscall.h to reflect which syscalls actually exist (on EABI)	2012-05-24 12:27:51 -04:00
Rich Felker	0b6eb2dfb2	update syscalls with off_t arguments to handle argument alignment, if needed ... the arm syscall abi requires 64-bit arguments to be aligned on an even register boundary. these new macros facilitate meeting the abi requirement without imposing significant ugliness on the code.	2011-09-21 20:11:10 -04:00
Rich Felker	d960d4f2cb	initial commit of the arm port ... 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.	2011-09-18 16:44:54 -04:00
