1 Revision history for SPIRV-Tools
4 - Published the C++ interface for assembling, disassembling, validation, and
8 - Support SPV_KHR_shader_ballot in assembler, disassembler, parser.
9 - Disassembler: Generate friendly names for built-in variables.
11 #359: Add Emacs helper for automatically diassembling/assembling a SPIR-V
12 binary on file load/save.
14 #414: Validator: Allow OpUndef for composite constants
15 #415: Validator: Phi can use its own value in some cases.
18 - Relicensed under Apache 2.0
19 - Add optimization passes (in API and spirv-opt command)
20 - Fold spec constants defined with OpSpecConstantOp and
21 OpSpecConstantComposite to normal constants with fixed value(s).
23 #318: Relicensed under Apache 2.0
26 - Add target environment enums for OpenCL 2.1, OpenCL 2.2,
27 OpenGL 4.0, OpenGL 4.1, OpenGL 4.2, OpenGL 4.3, OpenGL 4.5.
28 - Add spirv-cfg, an experimental tool to dump the control flow graph
29 as a GraphiViz "dot" graph
30 - Add optimization pass: Eliminate dead constants.
31 - Add spirv-lesspipe.sh filter utility
33 #288: Check def-use dominance rules for OpPhi (variable,parent) operands
34 #339: Allow OpUndef in types-constants-global-vars section, as required
35 by SPIR-V 1.0 Rev7, 1.1 Rev 3.
36 #340: Avoid race on mkdir during build
37 #365: Relax PointSize, ClipDistance, CullDistance capability check in all
38 environments not just Vulkan 1.0.
41 - Validator is incomplete
42 - Checks ID use block is dominated by definition block
43 - Add optimization passes (in API and spirv-opt command)
44 - Strip debug info instructions
45 - Freeze spec constant to their default values
46 - Allow INotEqual as operation for OpSpecConstantOp
48 #270: validator: crash when continue construct is unreachable
49 #279: validator: infinite loop when analyzing some degenerate control
51 #286: validator: don't incorrectly generate def-use error for
52 (variable,parent) parameters to OpPhi
53 #290: disassembler: never generate bare % for an identifier
54 #295: validator: def-use dominance check should ignore unreachable uses
55 #276: validator: allow unreachable continue constructs
56 #297: validator: allow an unreachable block to branch to a reachable
60 - Fix https://github.com/KhronosGroup/SPIRV-Tools/issues/261
61 Turn off ClipDistance and CullDistance capability checks for Vulkan.
62 - The disassembler can emit friendly names based on debug info (OpName
63 instructions), and will infer somewhat friendly names for most types.
64 This is turned on by default for the spirv-dis command line tool.
65 - Updated to support SPIR-V 1.1 rev 2
66 - Input StorageClass, Sampled1D capability, and SampledBuffer capability
67 do not require Shader capability anymore.
71 - Adds v<year>.<index> versioning, with "-dev" indicating
72 work in progress. The intent is to more easly report
73 and summarize functionality when SPIRV-Tools is incorporated
74 in downstream projects.
76 - Summary of functionality (See the README.md for more):
77 - Supports SPIR-V 1.1 Rev 1
78 - Supports SPIR-V 1.0 Rev 5
79 - Supports GLSL std450 extended instructions 1.0 Rev 3
80 - Supports OpenCL extended instructions 1.0 Rev 2
81 - Assembler, disassembler are complete
82 - Supports floating point widths of 16, 32, 64 bits
83 - Supports integer widths up to 64 bits
84 - Validator is incomplete
85 - Checks capability requirements in most cases
86 - Checks module layout constraints
87 - Checks ID use-definition ordering constraints,
89 - Checks some control flow graph rules
90 - Optimizer is introduced, with few available transforms.
91 - Supported on Linux, OSX, Android, Windows
94 - #143: OpenCL pow and pown arguments
