# glslangValidator ``` Usage: glslangValidator [option]... [file]... 'file' can end in .<stage> for auto-stage classification, where <stage> is: .conf to provide a config file that replaces the default configuration (see -c option below for generating a template) .vert for a vertex shader .tesc for a tessellation control shader .tese for a tessellation evaluation shader .geom for a geometry shader .frag for a fragment shader .comp for a compute shader .mesh for a mesh shader .task for a task shader .rgen for a ray generation shader .rint for a ray intersection shader .rahit for a ray any hit shader .rchit for a ray closest hit shader .rmiss for a ray miss shader .rcall for a ray callable shader .glsl for .vert.glsl, .tesc.glsl, ..., .comp.glsl compound suffixes .hlsl for .vert.hlsl, .tesc.hlsl, ..., .comp.hlsl compound suffixes Options: -C cascading errors; risk crash from accumulation of error recoveries -D input is HLSL (this is the default when any suffix is .hlsl) -D<name[=def]> | --define-macro <name[=def]> | --D <name[=def]> define a pre-processor macro -E print pre-processed GLSL; cannot be used with -l; errors will appear on stderr -G[ver] create SPIR-V binary, under OpenGL semantics; turns on -l; default file name is <stage>.spv (-o overrides this); 'ver', when present, is the version of the input semantics, which will appear in #define GL_SPIRV ver; '--client opengl100' is the same as -G100; a '--target-env' for OpenGL will also imply '-G'; currently only supports GLSL -H print human readable form of SPIR-V; turns on -V -I<dir> add dir to the include search path; includer's directory is searched first, followed by left-to-right order of -I -Od disables optimization; may cause illegal SPIR-V for HLSL -Os optimizes SPIR-V to minimize size -S <stage> uses specified stage rather than parsing the file extension choices for <stage> are vert, tesc, tese, geom, frag, or comp -U<name> | --undef-macro <name> | --U <name> undefine a pre-processor macro -V[ver] create SPIR-V binary, under Vulkan semantics; turns on -l; default file name is <stage>.spv (-o overrides this) 'ver', when present, is the version of the input semantics, which will appear in #define VULKAN ver '--client vulkan100' is the same as -V100 a '--target-env' for Vulkan will also imply '-V' -c configuration dump; creates the default configuration file (redirect to a .conf file) -d default to desktop (#version 110) when there is no shader #version (default is ES version 100) -e <name> | --entry-point <name> specify <name> as the entry-point function name -f{hlsl_functionality1} 'hlsl_functionality1' enables use of the SPV_GOOGLE_hlsl_functionality1 extension -g generate debug information -g0 strip debug information -h print this usage message -i intermediate tree (glslang AST) is printed out -l link all input files together to form a single module -m memory leak mode -o <file> save binary to <file>, requires a binary option (e.g., -V) -q dump reflection query database; requires -l for linking -r | --relaxed-errors relaxed GLSL semantic error-checking mode -s silence syntax and semantic error reporting -t multi-threaded mode -v | --version print version strings -w | --suppress-warnings suppress GLSL warnings, except as required by "#extension : warn" -x save binary output as text-based 32-bit hexadecimal numbers -u<name>:<loc> specify a uniform location override for --aml --uniform-base <base> set a base to use for generated uniform locations --auto-map-bindings | --amb automatically bind uniform variables without explicit bindings --auto-map-locations | --aml automatically locate input/output lacking 'location' (fragile, not cross stage) --client {vulkan<ver>|opengl<ver>} see -V and -G --dump-builtin-symbols prints builtin symbol table prior each compile -dumpfullversion | -dumpversion print bare major.minor.patchlevel --flatten-uniform-arrays | --fua flatten uniform texture/sampler arrays to scalars --hlsl-offsets allow block offsets to follow HLSL rules works independently of source language --hlsl-iomap perform IO mapping in HLSL register space --hlsl-enable-16bit-types allow 16-bit types in SPIR-V for HLSL --hlsl-dx9-compatible interprets sampler declarations as a texture/sampler combo like DirectX9 would, and recognizes DirectX9-specific semantics --invert-y | --iy invert position.Y output in vertex shader --keep-uncalled | --ku don't eliminate uncalled functions --nan-clamp favor non-NaN operand in min, max, and clamp --no-storage-format | --nsf use Unknown image format --quiet do not print anything to stdout, unless requested by another option --reflect-strict-array-suffix use strict array suffix rules when reflecting --reflect-basic-array-suffix arrays of basic types will have trailing [0] --reflect-intermediate-io reflection includes inputs/outputs of linked shaders rather than just vertex/fragment --reflect-separate-buffers reflect buffer variables and blocks separately to uniforms --reflect-all-block-variables reflect all variables in blocks, whether inactive or active --reflect-unwrap-io-blocks unwrap input/output blocks the same as uniform blocks --resource-set-binding [stage] name set binding set descriptor set and binding for individual resources --resource-set-binding [stage] set set descriptor set for all resources --rsb synonym for --resource-set-binding --shift-image-binding [stage] num base binding number for images (uav) --shift-image-binding [stage] [num set]... per-descriptor-set shift values --sib synonym for --shift-image-binding --shift-sampler-binding [stage] num base binding number for samplers --shift-sampler-binding [stage] [num set]... per-descriptor-set shift values --ssb synonym for --shift-sampler-binding --shift-ssbo-binding [stage] num base binding number for SSBOs --shift-ssbo-binding [stage] [num set]... per-descriptor-set shift values --sbb synonym for --shift-ssbo-binding --shift-texture-binding [stage] num base binding number for textures --shift-texture-binding [stage] [num set]... per-descriptor-set shift values --stb synonym for --shift-texture-binding --shift-uav-binding [stage] num base binding number for UAVs --shift-uav-binding [stage] [num set]... per-descriptor-set shift values --suavb synonym for --shift-uav-binding --shift-UBO-binding [stage] num base binding number for UBOs --shift-UBO-binding [stage] [num set]... per-descriptor-set shift values --sub synonym for --shift-UBO-binding --shift-cbuffer-binding | --scb synonyms for --shift-UBO-binding --spirv-dis output standard-form disassembly; works only when a SPIR-V generation option is also used --spirv-val execute the SPIRV-Tools validator --source-entrypoint <name> the given shader source function is renamed to be the <name> given in -e --sep synonym for --source-entrypoint --stdin read from stdin instead of from a file; requires providing the shader stage using -S --target-env {vulkan1.0 | vulkan1.1 | vulkan1.2 | opengl | spirv1.0 | spirv1.1 | spirv1.2 | spirv1.3 | spirv1.4 | spirv1.5} Set the execution environment that the generated code will be executed in. Defaults to: * vulkan1.0 under --client vulkan<ver> * opengl under --client opengl<ver> * spirv1.0 under --target-env vulkan1.0 * spirv1.3 under --target-env vulkan1.1 * spirv1.5 under --target-env vulkan1.2 Multiple --target-env can be specified. --variable-name <name> --vn <name> creates a C header file that contains a uint32_t array named <name> initialized with the shader binary code ```
