- * * inline assembly for Itanium-based HP-UX:
- *   http://h21007.www2.hp.com/portal/download/files/unprot/Itanium/inline_assem_ERS.pdf
- * * Implementing Spinlocks on the Intel (R) Itanium (R) Architecture and PA-RISC
- *   http://h21007.www2.hp.com/portal/download/files/unprot/itanium/spinlocks.pdf
- *
- * Itanium only supports a small set of numbers (6, -8, -4, -1, 1, 4, 8, 16)
- * for atomic add/sub, so we just implement everything but compare_exchange
- * via the compare_exchange fallbacks in atomics/generic.h.
