+ <!-- SECTION: SPIR-V Loop Control Bit Reservations -->
+ <!-- Reserve ranges of bits in the loop control bitfield.
+
+ Each vendor determines the use of values in their own ranges.
+ Vendors are not required to disclose those uses. If the use of a
+ value is included in an extension that is adopted by a Khronos
+ extension or specification, then that value's use may be permanently
+ fixed as if originally reserved in a Khronos range.
+
+ The SPIR Working Group strongly recommends:
+ - Each value is used for only one purpose.
+ - All values in a range should be used before allocating a new range.
