CLooG - The Chunky Loop Generator


cloog [ options | file ] ...


Options for code generation:
-l <depth>
Last loop depth to optimize (-1: infinity) (default setting: -1).

-f <depth>
First loop depth to start loop separation (-1: infinity) (default setting: 1).

-stop <depth>
Loop depth to stop code generation (-1: infinity) (default setting: -1).

-strides <boolean>
Handle non-unit strides (1) or not (0) (default setting: 0).

-first-unroll <depth> First loop dimension to unroll (-1: no unrolling)

Options for pretty printing:
-otl <boolean>
Simplify loops running one time (1) or not (0) (default setting: 1).

-esp <boolean>
Allow complex equalities spreading (1) or not (0) (default setting: 0).

-fsp <level>
First level to begin the spreading (default setting: 1).

-block <boolean>
Make a new statement block per iterator in C programs (1) or not (0) (default
setting: 0).

-compilable <number>
Compilable code by using preprocessor (not 0) or not (0), number being the value of
the parameters (default setting: 0).

-callable <boolean>
Testable code by using preprocessor (not 0) or not (0) (default setting: 0).

General options:
-o <output>
Name of the output file; 'stdout' is a special value: when used, output is standard
output (default setting: stdout).

-v, --version
Display the version information (and more).

-q, --quiet

-h, --help
Display this information.

The special value 'stdin' for 'file' makes CLooG to read data on standard input.
