R"(%s - Validate a SPIR-V binary file.
USAGE: %s [options] [<filename>]
The SPIR-V binary is read from <filename>. If no file is specified,
or if the filename is "-", then the binary is read from standard input.
NOTE: The validator is a work in progress.
Options:
-h, --help Print this help.
--max-struct-members <maximum number of structure members allowed>
--max-struct-depth <maximum allowed nesting depth of structures>
--max-local-variables <maximum number of local variables allowed>
--max-global-variables <maximum number of global variables allowed>
--max-switch-branches <maximum number of branches allowed in switch statements>
--max-function-args <maximum number arguments allowed per function>
--max-control-flow-nesting-depth <maximum Control Flow nesting depth allowed>
--max-access-chain-indexes <maximum number of indexes allowed to use for Access Chain instructions>
--max-id-bound <maximum value for the id bound>
--relax-logical-pointer Allow allocating an object of a pointer type and returning
a pointer value from a function in logical addressing mode
--relax-block-layout Enable VK_KHR_relaxed_block_layout when checking standard
uniform, storage buffer, and push constant layouts.
This is the default when targeting Vulkan 1.1 or later.
--uniform-buffer-standard-layout Enable VK_KHR_uniform_buffer_standard_layout when checking standard
uniform buffer layouts.
--scalar-block-layout Enable VK_EXT_scalar_block_layout when checking standard
uniform, storage buffer, and push constant layouts. Scalar layout
rules are more permissive than relaxed block layout so in effect
this will override the --relax-block-layout option.
--workgroup-scalar-block-layout Enable scalar block layout when checking Workgroup block layouts.
--skip-block-layout Skip checking standard uniform/storage buffer layout.
Overrides any --relax-block-layout or --scalar-block-layout option.
--relax-struct-store Allow store from one struct type to a
different type with compatible layout and
members.
--allow-localsizeid Allow use of the LocalSizeId decoration where it would otherwise not
be allowed by the target environment.
--before-hlsl-legalization Allows code patterns that are intended to be
fixed by spirv-opt's legalization passes.
--version Display validator version information.
--target-env {%s}
Use validation rules from the specified environment.
