<!-- SECTION: SPIR-V Memory Operand Bit Reservations -->
<!-- Reserve ranges of bits in the memory operands 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.
