Dear all,
We have extended our litmus testing infrastructure so as to handle C11
(small) programs.
I have just run Mark and Peter examples on one ARM system
(DragonBroard, running some old android)
with experimental gcc cross compiler with -O2
(arm-linux-gnueabi-gcc (GCC) 4.9.0 20140213 (experimental))
We exactly observe the results predicted by Peter in his note
on the first five examples (we cannot handle the sixth example yet)
