32 USAGE: %s [options] [<filename>]
33
34 The SPIR-V binary is read from <filename>. If no file is specified,
35 or if the filename is "-", then the binary is read from standard input.
36
37 NOTE: The validator is a work in progress.
38
39 Options:
40 -h, --help Print this help.
41 --max-struct-members <maximum number of structure members allowed>
42 --max-struct-depth <maximum allowed nesting depth of structures>
43 --max-local-variables <maximum number of local variables allowed>
44 --max-global-variables <maximum number of global variables allowed>
45 --max-switch-branches <maximum number of branches allowed in switch statements>
46 --max-function-args <maximum number arguments allowed per function>
47 --max-control-flow-nesting-depth <maximum Control Flow nesting depth allowed>
48 --max-access-chain-indexes <maximum number of indexes allowed to use for Access Chain instructions>
49 --max-id-bound <maximum value for the id bound>
50 --relax-logical-pointer Allow allocating an object of a pointer type and returning
51 a pointer value from a function in logical addressing mode
52 --relax-block-layout Enable VK_KHR_relaxed_block_layout when checking standard
53 uniform, storage buffer, and push constant layouts.
54 This is the default when targeting Vulkan 1.1 or later.
55 --uniform-buffer-standard-layout Enable VK_KHR_uniform_buffer_standard_layout when checking standard
56 uniform buffer layouts.
57 --scalar-block-layout Enable VK_EXT_scalar_block_layout when checking standard
58 uniform, storage buffer, and push constant layouts. Scalar layout
59 rules are more permissive than relaxed block layout so in effect
60 this will override the --relax-block-layout option.
61 --workgroup-scalar-block-layout Enable scalar block layout when checking Workgroup block layouts.
62 --skip-block-layout Skip checking standard uniform/storage buffer layout.
63 Overrides any --relax-block-layout or --scalar-block-layout option.
64 --relax-struct-store Allow store from one struct type to a
65 different type with compatible layout and
66 members.
67 --allow-localsizeid Allow use of the LocalSizeId decoration where it would otherwise not
68 be allowed by the target environment.
69 --before-hlsl-legalization Allows code patterns that are intended to be
70 fixed by spirv-opt's legalization passes.
71 --version Display validator version information.
72 --target-env {%s}
73 Use validation rules from the specified environment.
