Stacker is a simple stack based, Forth-like language that was written as a demonstration language for \s-1LLVM\s0. For details on the language, please see . The \fBstkrc\fR 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 \s-1LLVM\s0 tools for optimization and linking. .PP If \fIfilename\fR is omitted or is \f(CW\*(C`\-\*(C'\fR, then \fBstkrc\fR reads its input from standard input. This is useful for combining the tool into a pipeline. .PP If an output file is not specified with the \fB\-o\fR option, then \&\fBllvm-as\fR sends its output to a file or standard output by following these rules: .IP "\(bu" 4 If the input is standard input, then the output is standard output. .IP "\(bu" 4 If the input is a file that ends with \f(CW\*(C`.st\*(C'\fR, then the output file is of the same name, except that the suffix is changed to \f(CW\*(C`.bc\*(C'\fR. .IP "\(bu" 4 If the input is a file that does not end with the \f(CW\*(C`.st\*(C'\fR suffix, then the output file has the same name as the input file, except that the \f(CW\*(C`.bc\*(C'\fR suffix is appended. .SH "OPTIONS" .IX Header "OPTIONS" .IP "\fB\-o\fR \fIfilename\fR" 4 .IX Item "-o filename" Specify the output file name. If \fIfilename\fR is \f(CW\*(C`\-\*(C'\fR, then \fBllvm-as\fR sends its output to standard output. .IP "\fB\-stats\fR" 4 .IX Item "-stats" Print statistics acquired during compilation. .IP "\fB\-time\-passes\fR" 4 .IX Item "-time-passes" Record the amount of time needed for each pass and print it to standard error. .IP "\fB\-f\fR" 4 .IX Item "-f" Force the output to be written. Normally, \fBstkrc\fR won't overwrite an existing bytecode file. This option overrides that behavior. .IP "\fB\-s\fR \fIstacksize\fR" 4 .IX Item "-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. .IP "\fB\-help\fR" 4 .IX Item "-help" Print a summary of command line options. .SH "EXIT STATUS" .IX Header "EXIT STATUS" If \fBstkrc\fR succeeds, it will exit with 0. Otherwise, if an error occurs, it will exit with a non-zero value, usually 1. .SH "SEE ALSO" .IX Header "SEE ALSO" llvm-as, .SH "AUTHORS" .IX Header "AUTHORS" Maintained by the \s-1LLVM\s0 Team ().
