llvm-as-2.71

Usage

Overview

llvm-as is the LLVM assembler. It reads a file containing human-readable LLVM assembly language, translates it to LLVM bitcode, and writes the result into a file or to standard output.

If filename is omitted or is "-", then llvm-as reads its input from standard input.

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:

•

If the input is standard input, then the output is standard output.

•

If the input is a file that ends with ".ll", then the output file is of the same name, except that the suffix is changed to ".bc".

•

If the input is a file that does not end with the ".ll" suffix, then the output file has the same name as the input file, except that the ".bc" suffix is appended.

Options

-f

Enable binary output on terminals. Normally, llvm-as will refuse to write raw bitcode output if the output stream is a terminal. With this option, llvm-as will write raw bitcode regardless of the output device.

-help

Print a summary of command line options.

-o filename

Specify the output file name. If filename is "-", then llvm-as sends its output to standard output.

Exit status

If llvm-as succeeds, it will exit with 0. Otherwise, if an error occurs, it will exit with a non-zero value.
