<!-- SECTION: SPIR-V Tool ID Definitions -->
<!-- A SPIR-V Generator Magic Number is a 32 bit word: The high order 16
bits are a tool ID, which should be unique across all SPIR-V
generators. The low order 16 bits are reserved for use as a tool
version number, or any other purpose the tool supplier chooses.
Only the tool IDs are reserved with Khronos.
Add new tool ID reservations contiguously with the first available
number (the "start" attribute of the <unused> tag below), and
modify that <unused> tag accordingly. Please add a vendor/tool
supplier name in a 'vendor="name"' attribute; a tool name in a
'tool="name"' attribute; and a contact person/address in a
'comment' attribute. Remember that this value is the high 16 bits
of a 32-bit word.
Note: a single vendor/tool supplier may have multiple tool IDs
reserved for different SPIR-V generators -->

<!-- SECTION: SPIR-V Opcodes and Enumerants -->
<!-- Vendors reserve new ranges of:
- opcode enumerants in the "opcode" list below, and
- non-opcode enumerants in the non-opcodes "enumerant" list below.
Both are reserved by contiguous blocks of 64, preceding the given
"Future use" blocks.
SPIR-V background:
- SPIR-V currently has well over 30 enums, including the opcode enum
- each enum has its own name space, allowing reuse of enumerants
- SPIR-V restricts opcode enumerants to 16 bits
- all other enums use 32-bit enumerants
Reservation rules:
- opcode reservations ("opcode") are only valid for opcodes
- non-opcode reservations ("enumerant") are not valid for opcodes
- reservations in the enumerant list are valid for all non-opcode enums
- it is simpler to use each non-opcode enumerant for only one purpose
but this is left to the discretion of the vendor
- all enumerants in a range should be used before allocating a new range
(several extensions can use enumerants from the same range)
Each vendor determines the use of enumerants in the ranges they
reserve. Vendors are not required to disclose those uses. If the use
of an enumerant is included in an extension that is adopted by a Khronos
extension or specification, then that enumerant's use may be permanently
fixed as if originally reserved in a Khronos range.
