1 llvm-link - LLVM linker 2 ======================= 3 4 SYNOPSIS 5 -------- 6 7 :program:`llvm-link` [*options*] *filename ...* 8 9 DESCRIPTION 10 ----------- 11 12 :program:`llvm-link` takes several LLVM bitcode files and links them together 13 into a single LLVM bitcode file. It writes the output file to standard output, 14 unless the :option:`-o` option is used to specify a filename. 15 16 :program:`llvm-link` attempts to load the input files from the current 17 directory. If that fails, it looks for each file in each of the directories 18 specified by the :option:`-L` options on the command line. The library search 19 paths are global; each one is searched for every input file if necessary. The 20 directories are searched in the order they were specified on the command line. 21 22 OPTIONS 23 ------- 24 25 .. option:: -L directory 26 27 Add the specified ``directory`` to the library search path. When looking for 28 libraries, :program:`llvm-link` will look in path name for libraries. This 29 option can be specified multiple times; :program:`llvm-link` will search 30 inside these directories in the order in which they were specified on the 31 command line. 32 33 .. option:: -f 34 35 Enable binary output on terminals. Normally, :program:`llvm-link` will refuse 36 to write raw bitcode output if the output stream is a terminal. With this 37 option, :program:`llvm-link` will write raw bitcode regardless of the output 38 device. 39 40 .. option:: -o filename 41 42 Specify the output file name. If ``filename`` is "``-``", then 43 :program:`llvm-link` will write its output to standard output. 44 45 .. option:: -S 46 47 Write output in LLVM intermediate language (instead of bitcode). 48 49 .. option:: -d 50 51 If specified, :program:`llvm-link` prints a human-readable version of the output 52 bitcode file to standard error. 53 54 .. option:: -help 55 56 Print a summary of command line options. 57 58 .. option:: -v 59 60 Verbose mode. Print information about what :program:`llvm-link` is doing. 61 This typically includes a message for each bitcode file linked in and for each 62 library found. 63 64 EXIT STATUS 65 ----------- 66 67 If :program:`llvm-link` succeeds, it will exit with 0. Otherwise, if an error 68 occurs, it will exit with a non-zero value. 69 70 SEE ALSO 71 -------- 72 73 gccld 74 75
