Subject: Allow to disable spinlocks
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=6645115377bd9699ae6785608753d33067b8e036;hp=6645115377bd9699ae6785608753d33067b8e036

Allow to disable spinlocks

And use mutex instead. You may never want to do this.
It is a workaround to run c++11 on fishtest where many
machiens have HTenabled and this can be a problem when
number of cores set is higher than number of physical cores.

To disable spinlocks, just compile with -DNO_SPINLOCK flag

No functional change.
