If + not passed the ethread library (part of the runtime system) will use + instructions that first appeared on the pentium 4 processor when building + for x86. This option will be automatically enabled if required on the + build machine. +* `--with-libatomic_ops=PATH` - Use the `libatomic_ops` library for atomic + memory accesses. If `configure` should inform you about no native atomic + implementation available, you typically want to try using the + `libatomic_ops` library. It can be downloaded from + <http://www.hpl.hp.com/research/linux/atomic_ops/>. If you or your system has special requirements please read the `Makefile` for additional configuration information. |
