+;; CHECK:      wasm-reduce INFILE
+;; CHECK-NEXT:
+;; CHECK-NEXT: Reduce a wasm file to a smaller one that has the same behavior on a given
+;; CHECK-NEXT: command

+;; CHECK-NEXT: Options:
+;; CHECK-NEXT:
+;; CHECK-NEXT:   --version         Output version information and exit

+;; CHECK-NEXT:
+;; CHECK-NEXT:   --debug,-d        Print debug information to stderr
+;; CHECK-NEXT:
+;; CHECK-NEXT:   --command,-cmd    The command to run on the test, that we want to reduce while
+;; CHECK-NEXT:                     keeping the command's output identical. We look at the
+;; CHECK-NEXT:                     command's return code and stdout here (TODO: stderr), and we
+;; CHECK-NEXT:                     reduce while keeping those unchanged.
+;; CHECK-NEXT:
+;; CHECK-NEXT:   --test,-t         Test file (this will be written to to test, the given
+;; CHECK-NEXT:                     command should read it when we call it)
+;; CHECK-NEXT:
+;; CHECK-NEXT:   --working,-w      Working file (this will contain the current good state while
+;; CHECK-NEXT:                     doing temporary computations, and will contain the final
+;; CHECK-NEXT:                     best result at the end)
+;; CHECK-NEXT:
+;; CHECK-NEXT:   --binaries,-b     binaryen binaries location (bin/ directory)
+;; CHECK-NEXT:
+;; CHECK-NEXT:   --text,-S         Emit intermediate files as text, instead of binary (also
+;; CHECK-NEXT:                     make sure the test and working files have a .wat or .wast
+;; CHECK-NEXT:                     suffix)
+;; CHECK-NEXT:
+;; CHECK-NEXT:   --denan           Avoid nans when reducing

+;; CHECK-NEXT:
+;; CHECK-NEXT:   --debugInfo,-g    Keep debug info in binaries
+;; CHECK-NEXT:
+;; CHECK-NEXT:   --force,-f        Force the reduction attempt, ignoring problems that imply it
+;; CHECK-NEXT:                     is unlikely to succeed
+;; CHECK-NEXT:
+;; CHECK-NEXT:   --timeout,-to     A timeout to apply to each execution of the command, in
+;; CHECK-NEXT:                     seconds (default: 2)
+;; CHECK-NEXT:
+;; CHECK-NEXT:   --extra-flags,-ef Extra commandline flags to pass to wasm-opt while reducing.
+;; CHECK-NEXT:                     (default: --enable-all)
