| NAME |
| </h3> |
| |
| llvm-as |
| |
| <h3> |
| SYNOPSIS |
| </h3> |
| |
| llvm-as [options] [filename] |
| <h3> |
| DESCRIPTION |
| </h3> |
| |
| The llvm-as command is the LLVM assembler. It reads a file containing human |
| readable LLVM assembly language, translates it to LLVM bytecode, and writes the |
| result into a file or to standard output. |
| <p> |
| |
| If filename is omitted or is -, then llvm-as reads its input from standard |
| input. |
| <p> |
| |
| If an output file is not specified with the -o option, then llvm-as sends its |
| output to a file or standard output by the following logic: |
| |
| <ul> |
| <li> |
| If the input is standard input, then the output is standard output. |
| <p> |
| |
| <li> |
| 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. |
| <p> |
| |
| <li> |
| 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. |
| <p> |
| </ul> |
| |
| <h3> |
| OPTIONS |
| </h3> |
| |
| <ul> |
| <li> -f |
| <br> |
| Force overwrite. Normally, llvm-as will refuse to overwrite an output |
| file that already exists. With this option, llvm-as will overwrite the |
| output file and replace it with new bytecode. |
| <p> |
| |
| <li> -help |
| <br> |
| Print a summary of command line options. |
| <p> |
| |
| <li> -o <filename> |
| <br> |
| Specify the output filename. If filename is -, then llvm-as sends its |
| output to standard output. |
| <p> |
| |
| <li> -stats |
| <br> |
| Print statistics. |
| <p> |
| |
| <li> -time-passes |
| <br> |
| Record the amount of time needed for each pass and print it to standard |
| error. |
| <p> |
| </ul> |
| |
| <h3> |
| EXIT STATUS |
| </h3> |
| |
| If llvm-as succeeds, it will exit with 0. Otherwise, if an error occurs, it |
| will exit with a non-zero value. |
