;; RUN: wasm-split --help | filecheck %s
;; CHECK: ================================================================================
;; CHECK-NEXT: wasm-split INFILES
;; CHECK-NEXT:
;; CHECK-NEXT: Split a module into a primary module and a secondary module, or instrument a
;; CHECK-NEXT: module to gather a profile that can inform future splitting, or manage such
;; CHECK-NEXT: profiles. Options that are only accepted in particular modes are marked with the
;; CHECK-NEXT: accepted "[<modes>]" in their descriptions.
;; CHECK-NEXT: ================================================================================
;; CHECK-NEXT:
;; CHECK-NEXT:
;; CHECK-NEXT: wasm-split options:
;; CHECK-NEXT: -------------------
;; CHECK-NEXT:
;; CHECK-NEXT: --split Split an input module into two output
;; CHECK-NEXT: modules. The default mode.
;; CHECK-NEXT:
;; CHECK-NEXT: --multi-split Split an input module into an arbitrary
;; CHECK-NEXT: number of output modules.
;; CHECK-NEXT:
;; 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:
;; CHECK-NEXT: --merge-profiles Merge multiple profiles for the same
;; CHECK-NEXT: module into a single profile.
;; CHECK-NEXT:
;; CHECK-NEXT: --print-profile [print-profile] Print profile contents in
;; CHECK-NEXT: a human-readable format.
;; CHECK-NEXT:
;; CHECK-NEXT: --profile [split] The profile to use to guide
;; CHECK-NEXT: splitting.
;; CHECK-NEXT:
;; CHECK-NEXT: --keep-funcs [split] Comma-separated list of functions
;; CHECK-NEXT: to keep in the primary module. The rest
;; CHECK-NEXT: will be split out. Can be used alongside
;; CHECK-NEXT: --profile and --split-funcs. You can also
;; CHECK-NEXT: pass a file with one function per line by
;; CHECK-NEXT: passing @filename.
;; CHECK-NEXT:
;; CHECK-NEXT: --split-funcs [split] Comma-separated list of functions
;; CHECK-NEXT: to split out to the secondary module. The
;; CHECK-NEXT: rest will be kept. Can be used alongside
;; CHECK-NEXT: --profile and --keep-funcs. This takes
;; CHECK-NEXT: precedence over other split options. You
;; CHECK-NEXT: can also pass a file with one function
;; CHECK-NEXT: per line by passing @filename.
;; CHECK-NEXT:
;; CHECK-NEXT: --manifest [multi-split] File describing the
;; CHECK-NEXT: functions to be split into each module.
;; CHECK-NEXT: Each section separated by a blank line
;; CHECK-NEXT: begins with the base name of an output
;; CHECK-NEXT: module, which is followed by a list of
;; CHECK-NEXT: functions to place in that module, one
;; CHECK-NEXT: per line.
;; CHECK-NEXT:
;; CHECK-NEXT: --out-prefix [multi-split] Prefix prepended to module
;; CHECK-NEXT: names in the manifest file to create
;; CHECK-NEXT: output file names.
;; CHECK-NEXT:
;; CHECK-NEXT: --primary-output,-o1 [split] Output file for the primary
;; CHECK-NEXT: module.
;; CHECK-NEXT:
;; CHECK-NEXT: --secondary-output,-o2 [split] Output file for the secondary
;; CHECK-NEXT: module.
;; CHECK-NEXT:
;; CHECK-NEXT: --symbolmap [split] Write a symbol map file for each
;; CHECK-NEXT: of the output modules.
;; CHECK-NEXT:
;; CHECK-NEXT: --no-placeholders [split] Do not import placeholder
;; CHECK-NEXT: functions. Calls to secondary functions
;; CHECK-NEXT: will fail before the secondary module has
;; CHECK-NEXT: been instantiated.
;; CHECK-NEXT:
;; CHECK-NEXT: --placeholdermap [split] Write a file mapping placeholder
;; CHECK-NEXT: indices to the function names.
;; CHECK-NEXT:
;; CHECK-NEXT: --import-namespace [split, instrument] When provided as an
;; CHECK-NEXT: option for module splitting, the
;; CHECK-NEXT: namespace from which to import objects
;; CHECK-NEXT: from the primary module into the
;; CHECK-NEXT: secondary module. In instrument mode,
;; CHECK-NEXT: refers to the namespace from which to
;; CHECK-NEXT: import the secondary memory, if any.
;; CHECK-NEXT:
;; CHECK-NEXT: --placeholder-namespace [split] The namespace from which to
;; CHECK-NEXT: import placeholder functions into the
;; CHECK-NEXT: primary module.
;; CHECK-NEXT:
;; CHECK-NEXT: --jspi [split] Transform the module to support
;; CHECK-NEXT: asynchronously loading the secondary
;; CHECK-NEXT: module before any placeholder functions
;; CHECK-NEXT: have been called.
;; CHECK-NEXT:
;; CHECK-NEXT: --export-prefix [split] An identifying prefix to prepend
;; CHECK-NEXT: to new export names created by module
;; CHECK-NEXT: splitting.
;; CHECK-NEXT:
;; 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:
;; CHECK-NEXT: --in-memory [instrument] Store profile information in
;; CHECK-NEXT: memory (starting at address 0 and taking
;; CHECK-NEXT: one byte per function) rather than
;; CHECK-NEXT: globals (the default) so that it can be
;; CHECK-NEXT: shared between multiple threads. Users
;; CHECK-NEXT: are responsible for ensuring that the
;; CHECK-NEXT: module does not use the initial memory
;; CHECK-NEXT: region for anything else.
;; CHECK-NEXT:
;; CHECK-NEXT: --in-secondary-memory [instrument] Store profile information in
;; CHECK-NEXT: a separate memory, rather than in module
;; CHECK-NEXT: main memory or globals (the default).
;; CHECK-NEXT: With this option, users do not need to
;; CHECK-NEXT: reserve the initial memory region for
;; CHECK-NEXT: profile data and the data can be shared
;; CHECK-NEXT: between multiple threads.
;; CHECK-NEXT:
;; CHECK-NEXT: --secondary-memory-name [instrument] The name of the secondary
;; CHECK-NEXT: memory created to store profile
;; CHECK-NEXT: information.
;; CHECK-NEXT:
;; 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:
;; 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:
;; CHECK-NEXT: --emit-text,-S [split, instrument] Emit text instead of
;; CHECK-NEXT: binary for the output file or files.
;; CHECK-NEXT:
;; CHECK-NEXT: --debuginfo,-g [split, multi-split, instrument] Emit
;; CHECK-NEXT: names section in wasm binary (or full
;; CHECK-NEXT: debuginfo in wast)
;; CHECK-NEXT:
;; CHECK-NEXT: --output,-o [instrument, merge-profiles, multi-split]
;; CHECK-NEXT: Output file.
;; CHECK-NEXT:
;; CHECK-NEXT: --unescape,-u Un-escape function names (in
;; CHECK-NEXT: print-profile output)
;; CHECK-NEXT:
;; 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:
;; CHECK-NEXT:
;; CHECK-NEXT: Tool options:

;; CHECK-NEXT: --mvp-features,-mvp Disable all non-MVP features
;; CHECK-NEXT:
;; CHECK-NEXT: --all-features,-all Enable all features
