joerg aa565dfb01 Add unused memory model argument to make GCC happy. 2014-07-06 01:19:45 +00:00
joerg 3ba4836216 Provide a basic implementation of __atomic_load_* and __atomic_store_*,
used by GCC and LLVM as backing for C11/C++11 atomics, if the hardware
is not known to have corresponding features. Include it on ARM as LLVM
and libc++ hit it when compiled for ARMv4.

christos 57561cf1db The kernel uses 64 bit atomic ops. 2014-04-22 19:27:17 +00:00
joerg e3dae42754 Undef possible macro versions of memcpy and friends for kernel builds
too. libkern sometimes defines them to the builtins.

joerg a33c368664 Using bcopy/memcpy with NULL arguments is valid as long as the size is
also 0.

jakllsch 6ac3c1f4d7 For all x86_64 string assembly functions that don't overlap (i.e. every
one except memset and bzero) use END() so that symbol size information
is available.

riastradh 6cb10275d0 Merge riastradh-drm2 to HEAD. 2014-03-18 18:20:35 +00:00
riastradh 0766111859 Fix subword atomic_cas.
- Don't loop forever on failure.
- Don't shift away the result and return zero on success.

Evidently we lack automatic tests for these!
