   -D NM=VAL  emit macro definition into generated C code
   -B NM=VAL  pass option to kbuild make

              include a MODULE_INFO(NM,VAL) in the generated C code
   -G VAR=VAL set global variable to value
   -R DIR     look in DIR for runtime, instead of
              /usr/share/systemtap/runtime
   -r DIR     cross-compile to kernel with given build tree; or else
   -r RELEASE cross-compile to kernel /lib/modules/RELEASE/build, instead of

   -a ARCH    cross-compile to given architecture, instead of x86_64
   -m MODULE  set probe module name, instead of
              stap_2

              strftime(3) formats for FILE
   -E SCRIPT  run the SCRIPT in addition to the main script specified
              through -e or a script file

   -x PID     sets target() to PID
   -F         run as on-file flight recorder with -o.

   -S size[,n] set maximum of the size and the number of files.
   -d OBJECT  add unwind/symbol data for OBJECT file
   --ldd      add unwind/symbol data for referenced user-space objects.
   --all-modules
              add unwind/symbol data for all loaded kernel objects.
   -t         collect probe timing information
   -T TIME    terminate the script after TIME seconds
   -q         generate information on tapset coverage
   --runtime=MODE
              set the pass-5 runtime mode, instead of kernel
   --bpf
              shorthand for --runtime=bpf
   --prologue-searching[=WHEN]
              prologue-searching for function probes
   --privilege=PRIVILEGE_LEVEL
              check the script for constructs not allowed at the given privilege level
   --unprivileged
              equivalent to --privilege=stapusr

              retry compilation using a compile server upon compilation error

   --sysenv=VAR=VALUE
              provide an alternate value for an environment variable
