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

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