futhark c [options…] <program.fut>
futhark c translates a Futhark program to sequential C code, and
either compiles that C code with gcc(1) to an executable binary
program, or produces a
.c file that can be linked with
other code.. The standard Futhark optimisation pipeline is used, and
GCC is invoked with
The resulting program will read the arguments to the entry point
main by default) from standard input and print its return value
on standard output. The arguments are read and printed in Futhark
Print help text to standard output and exit.
Generate a library instead of an executable. Appends
.hto the name indicated by the
-ooption to determine output file names.
- -o outfile
Where to write the result. If the source program is named
foo.fut, this defaults to
unsafein program and perform safety checks unconditionally.
- -v verbose
Enable debugging output. If compilation fails due to a compiler error, the result of the last successful compiler step will be printed to standard error.
Print version information on standard output and exit.
Do not print any warnings.
Treat warnings as errors.
The following options are accepted by executables generated by
- -b, --binary-output
Print the program result in the binary output format. The default is human-readable text, which is very slow.
- -D, --debugging
Perform possibly expensive internal correctness checks and verbose logging. Implies
- -e, --entry-point=FUN
The entry point to run. Defaults to
- -L, --log
Print various low-overhead logging information to stderr while running.
- -r, --runs=NUM
Perform NUM runs of the program. With
-t, the runtime for each individual run will be printed. Additionally, a single leading warmup run will be performed (not counted). Only the final run will have its result written to stdout.
- -t, --write-runtime-to=FILE
Print the time taken to execute the program to the indicated file, an integral number of microseconds.
