Options that are only accepted in particular modes are marked with the +CHECK-NEXT: accepted "[<modes>]" in their descriptions. +CHECK-NEXT: +CHECK-NEXT: Options: + +;; Skip standard tool options + +CHECK: --split Split an input module into two output +CHECK-NEXT: modules. The default mode. +CHECK-NEXT: --instrument Instrument an input module to allow it to +CHECK-NEXT: generate a profile that can be used to +CHECK-NEXT: guide splitting. +CHECK-NEXT: --profile [split] The profile to use to guide +CHECK-NEXT: splitting. +CHECK-NEXT: --keep-funcs [split] Comma-separated list of functions +CHECK-NEXT: to keep in the primary module, regardless +CHECK-NEXT: of any profile. +CHECK-NEXT: --split-funcs [split] Comma-separated list of functions +CHECK-NEXT: to split into the secondary module, +CHECK-NEXT: regardless of any profile. If there is no +CHECK-NEXT: profile, then this defaults to all +CHECK-NEXT: functions defined in the module. +CHECK-NEXT: --primary-output,-o1 [split] Output file for the primary +CHECK-NEXT: module. +CHECK-NEXT: --secondary-output,-o2 [split] Output file for the secondary +CHECK-NEXT: module. +CHECK-NEXT: --symbolmap [split] Write a symbol map file for each +CHECK-NEXT: of the output modules. +CHECK-NEXT: --import-namespace [split] The namespace from which to +CHECK-NEXT: import objects from the primary module +CHECK-NEXT: into the secondary module. +CHECK-NEXT: --placeholder-namespace [split] The namespace from which to +CHECK-NEXT: import placeholder functions into the +CHECK-NEXT: primary module. +CHECK-NEXT: --export-prefix [split] An identifying prefix to prepend +CHECK-NEXT: to new export names created by module +CHECK-NEXT: splitting. +CHECK-NEXT: --output,-o [instrument] Output file. +CHECK-NEXT: --profile-export [instrument] The export name of the +CHECK-NEXT: function the embedder calls to write the +CHECK-NEXT: profile into memory. Defaults to +CHECK-NEXT: `__write_profile`. +CHECK-NEXT: --emit-module-names [split, instrument] Emit module names, +CHECK-NEXT: even if not emitting the rest of the +CHECK-NEXT: names section. Can help differentiate the +CHECK-NEXT: modules in stack traces. This option will +CHECK-NEXT: be removed once simpler ways of naming +CHECK-NEXT: modules are widely available. See +CHECK-NEXT: https://bugs.chromium.org/p/v8/issues/detail?id=11808. +CHECK-NEXT: --initial-table [split, instrument] A hack to ensure the +CHECK-NEXT: split and instrumented modules have the +CHECK-NEXT: same table size when using Emscripten's +CHECK-NEXT: SPLIT_MODULE mode with dynamic linking. +CHECK-NEXT: TODO: Figure out a more elegant solution +CHECK-NEXT: for that use case and remove this. +CHECK-NEXT: --verbose,-v Verbose output mode. Prints the functions +CHECK-NEXT: that will be kept and split out when +CHECK-NEXT: splitting a module. +CHECK-NEXT: --emit-text,-S Emit text instead of binary for the +CHECK-NEXT: output file or files. +CHECK-NEXT: --debuginfo,-g Emit names section in wasm binary (or +CHECK-NEXT: full debuginfo in wast) |
