The space between - D and <name> is optional. If no <value> is specified, Slang will define the macro with an empty value. ### -depfile **-depfile <path>** Save the source file dependency list in a file. ### -entry **-entry <name>** Specify the name of an entry-point function. When compiling from a single file, this defaults to main if you specify a stage using [-stage](#stage-1). Multiple [-entry](#entry) options may be used in a single invocation. When they do, the file associated with the entry point will be the first one found when searching to the left in the command line. If no [-entry](#entry) options are given, compiler will use \[shader(...)\] attributes to detect entry points. ### -specialize **-specialize <typename>** Specialize the last entrypoint with <typename>. ### -emit-ir Emit IR typically as a '.slang-module' when outputting to a container. ### -h, -help, --help **-h or -h <[help-category](#help-category)>** Print this message, or help in specified category. ### -help-style **-help-style <[help-style](#help-style)>** Help formatting style ### -I **-I<path>, -I <path>** Add a path to be used in resolving '#include' and 'import' operations. ### -lang **-lang <[language](#language)>** Set the language for the following input files. ### -matrix-layout-column-major Set the default matrix layout to column-major. ### -matrix-layout-row-major Set the default matrix layout to row-major. ### -restrictive-capability-check Many capability warnings will become an error. ### -ignore-capabilities Do not warn or error if capabilities are violated ### -minimum-slang-optimization Perform minimum code optimization in Slang to favor compilation time. ### -disable-non-essential-validations Disable non-essential IR validations such as use of uninitialized variables. ### -disable-source-map Disable source mapping in the Obfuscation. ### -module-name **-module-name <name>** Set the module name to use when compiling multiple .slang source files into a single module. ### -o **-o <path>** Specify a path where generated output should be written. If no [-target](#target-2) or [-stage](#stage-1) is specified, one may be inferred from file extension (see [<file-extension>](#file-extension)). If multiple [-target](#target-2) options and a single [-entry](#entry) are present, each [-o](#o) associates with the first [-target](#target-2) to its left. Otherwise, if multiple [-entry](#entry) options are present, each [-o](#o) associates with the first [-entry](#entry) to its left, and with the [-target](#target-2) that matches the one inferred from <path>. ### -profile **-profile <profile>\[+<[capability](#capability)>...\]** Specify the shader profile for code generation. Accepted profiles are: * sm_{4_0,4_1,5_0,5_1,6_0,6_1,6_2,6_3,6_4,6_5,6_6,6_7,6_8,6_9,6_10} * glsl_{110,120,130,140,150,330,400,410,420,430,440,450,460} Additional profiles that include [-stage](#stage-1) information: * {vs,hs,ds,gs,ps}_<version> See [-capability](#capability-1) for information on [<capability>](#capability) When multiple [-target](#target-2) options are present, each [-profile](#profile) associates with the first [-target](#target-2) to its left. ### -stage **-stage <[stage](#stage)>** Specify the stage of an entry-point function. When multiple [-entry](#entry) options are present, each [-stage](#stage-1) associated with the first [-entry](#entry) to its left. May be omitted if entry-point function has a \[shader(...)\] attribute; otherwise required for each [-entry](#entry) option. ### -target **-target <[target](#target-1)>** Specifies the format in which code should be generated. ### -v, -version Display the build version. This is the contents of git describe --tags. It is typically only set from automated builds(such as distros available on github).A user build will by default be 'unknown'. ### -std **-std <[language-version](#language-version)>** Specifies the language standard that should be used. ### -warnings-as-errors **-warnings-as-errors all or -warnings-as-errors <id>\[,<id>...\]** all - Treat all warnings as errors. <id>\[,<id>...\]: Treat specific warning ids as errors. ### -warnings-disable **-warnings-disable <id>\[,<id>...\]** Disable specific warning ids. ### -W **-W<id>** Enable a warning with the specified id. ### -Wno- **-Wno-<id>** Disable warning with <id> ### -dump-warning-diagnostics Dump to output list of warning diagnostic numeric and name ids. ### -- Treat the rest of the command line as input files. ### -report-downstream-time Reports the time spent in the downstream compiler. ### -report-perf-benchmark Reports compiler performance benchmark results. ### -report-detailed-perf-benchmark Reports compiler performance benchmark results for each intermediate pass (implies [-report-perf-benchmark](#report-perf-benchmark)). ### -report-checkpoint-intermediates Reports information about checkpoint contexts used for reverse-mode automatic differentiation. ### -trace-coverage Instrument the shader with per-statement execution counters. When writing compiled output to a file, slangc also emits `<output>.coverage-mapping.json` mapping counter slots to source positions. ### -trace-coverage-binding **-trace-coverage-binding <index> <space>** Bind the synthesized `__slang_coverage` buffer at an explicit (register index, space) instead of auto-allocating a slot. Useful when the host needs the binding fixed at compile time before any host metadata reads run. Implies `-trace-coverage`. ### -trace-coverage-reserved-space **-trace-coverage-reserved-space <space>** Reserve a descriptor set when auto-allocating the synthesized `__slang_coverage` buffer. Use this when the host pipeline layout owns descriptor sets that are not visible in the compiled shader IR. Repeat for multiple spaces; duplicates are idempotent. Applies to Khronos descriptor-set targets. ### -report-dynamic-dispatch-sites Reports information about dynamic dispatch sites for interface calls. ### -skip-spirv-validation Skips spirv validation. ### -source-embed-style **-source-embed-style <[source-embed-style](#source-embed-style)>** If source embedding is enabled, defines the style used. When enabled (with any style other than `none`), will write compile results into embeddable source for the target language. If no output file is specified, the output is written to stdout. If an output file is specified it is written either to that file directly (if it is appropriate for the target language), or it will be output to the filename with an appropriate extension. Note for C/C++ with u16/u32/u64 types it is necessary to have "#include <stdint.h>" before the generated file. ### -source-embed-name **-source-embed-name <name>** The name used as the basis for variables output for source embedding. ### -source-embed-language **-source-embed-language <[language](#language)>** The language to be used for source embedding.

(Note: enum class remains scoped.) ### -preserve-params Preserve all resource parameters in the output code, even if they are not used by the shader. ### -conformance **-conformance <typeName>:<interfaceName>\[=<sequentialID>\]** Include additional type conformance during linking for dynamic dispatch. ### -reflection-json **-reflection-json <path>** Emit reflection data in JSON format to a file. ### -msvc-style-bitfield-packing Pack bitfields according to MSVC rules (msb first, new field when underlying type size changes) rather than gcc-style (lsb first) ## Target Target code generation options ### -capability **-capability <[capability](#capability)>\[+<[capability](#capability)>...\]** Add optional capabilities to a code generation target. See Capabilities below. ### -default-image-format-unknown Set the format of R/W images with unspecified format to 'unknown'. Otherwise try to guess the format. ### -disable-dynamic-dispatch Disables generating dynamic dispatch code. ### -disable-specialization Disables generics and specialization pass. ### -fp-mode, -floating-point-mode **-fp-mode <[fp-mode](#fp-mode)>, -floating-point-mode <[fp-mode](#fp-mode)>** Control floating point optimizations ### -denorm-mode-fp16 **-denorm-mode-fp16 <[fp-denormal-mode](#fp-denormal-mode)>** Control handling of 16-bit denormal floating point values in SPIR-V (any, preserve, ftz) ### -denorm-mode-fp32 **-denorm-mode-fp32 <[fp-denormal-mode](#fp-denormal-mode)>** Control handling of 32-bit denormal floating point values in SPIR-V and DXIL (any, preserve, ftz) ### -denorm-mode-fp64 **-denorm-mode-fp64 <[fp-denormal-mode](#fp-denormal-mode)>** Control handling of 64-bit denormal floating point values in SPIR-V (any, preserve, ftz) ### -g **-g, -g<[debug-info-format](#debug-info-format)>, -g<[debug-level](#debug-level)>** Include debug information in the generated code, where possible. [<debug-level>](#debug-level) is the amount of information, 0..3, unspecified means 2 [<debug-info-format>](#debug-info-format) specifies a debugging info format It is valid to have multiple [-g](#g) options, such as a [<debug-level>](#debug-level) and a [<debug-info-format>](#debug-info-format) ### -line-directive-mode **-line-directive-mode <[line-directive-mode](#line-directive-mode)>** Sets how the `#line` directives should be produced. Available options are: If not specified, default behavior is to use C-style `#line` directives for HLSL and C/C++ output, and traditional GLSL-style `#line` directives for GLSL output. ### -O **-O<[optimization-level](#optimization-level)>** Set the optimization level. ### -obfuscate Remove all source file information from outputs. ### -force-glsl-scalar-layout, -fvk-use-scalar-layout Make data accessed through ConstantBuffer, ParameterBlock, StructuredBuffer, ByteAddressBuffer and general pointers follow the 'scalar' layout when targeting GLSL or SPIRV. ### -fvk-use-dx-layout Pack members using FXCs member packing rules when targeting GLSL or SPIRV. ### -fvk-use-c-layout Make data accessed through ConstantBuffer, ParameterBlock, StructuredBuffer, ByteAddressBuffer and general pointers follow the C/C++ structure layout rules when targeting SPIRV. ### -fvk-<vulkan-shift>-shift **-fvk-<[vulkan-shift](#vulkan-shift)>-shift <N> <space>** For example '-fvk-b-shift <N> <space>' shifts by N the inferred binding numbers for all resources in 'b' registers of space <space>. For a resource attached with :register(bX, <space>) but not \[vk::binding(...)\], sets its Vulkan descriptor set to <space> and binding number to X + N. If you need to shift the inferred binding numbers for more than one space, provide more than one such option. If more than one such option is provided for the same space, the last one takes effect. If you need to shift the inferred binding numbers for all sets, use 'all' as <space>.
