Rich Felker	884cc0c7e2	fix microblaze atomic store as far as I can tell, microblaze is strongly ordered, but this does not seem to be well-documented and the assumption may need revisiting. even with strong ordering, however, a volatile C assignment is not sufficient to implement atomic store, since it does not preclude reordering by the compiler with respect to non-volatile stores and loads. simply flanking a C store with empty volatile asm blocks with memory clobbers would achieve the desired result, but is likely to result in worse code generation, since the address and value for the store may need to be spilled. actually writing the store in asm, so that there's only one asm block, should give optimal code generation while satisfying the requirement for having a compiler barrier.	12 years ago

Rich Felker	7568ee4cbf	add missing a_or_l to atomic.h for non-x86 archs this is needed for recently committed sigaction code	13 years ago
Rich Felker	8c0a3d9e5c	microblaze port based on initial work by rdp, with heavy modifications. some features including threads are untested because qemu app-level emulation seems to be broken and I do not have a proper system image for testing.	14 years ago
Rich Felker	a3bdcd9376	remove little-endian assumption from arm atomic.h this hidden endian dependency had left big endian arm badly broken.	14 years ago
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.	15 years ago
