NAME

stkrc - Stacker Compiler

SYNOPSIS

stkrc [options] [filename]

DESCRIPTION

The stkrc command is the compiler for the Stacker language. Stacker is a simple stack based, Forth-like language that was written as a demonstration language for LLVM. For details on the language, please see http://llvm.cs.uiuc.edu/docs/Stacker.html . The stkrc compiler is fairly minimal. It compiles to bytecode only and doesn't perform any optimizations. The output of stkrc (a bytecode file) can be piped through other LLVM tools for optimization and linking.

If filename is omitted or is -, then stkrc reads its input from standard input. This is useful for combining the tool into a pipeline.

If an output file is not specified with the -o option, then llvm-as sends its output to a file or standard output by following these rules:

.st

.bc

.st

.bc

OPTIONS

-o filename: Specify the output file name. If filename is -, then llvm-as sends its output to standard output.
-stats: Print statistics acquired during compilation.
-time-passes: Record the amount of time needed for each pass and print it to standard error.
-f: Force the output to be written. Normally, stkrc won't overwrite an existing bytecode file. This option overrides that behavior.
-s stacksize: Specify the stack size for the program. The default stack size, 1024, should be sufficient for most programs. For very large programs, especially those that recurse a lot, you might want to provide a larger value. Each unit of this value consumes 8 bytes of memory.
-help: Print a summary of command line options.

EXIT STATUS

If stkrc succeeds, it will exit with 0. Otherwise, if an error occurs, it will exit with a non-zero value, usually 1.
