It writes the output file to standard output, unless 15 the B<-o> option is used to specify a filename. 16 17 B<llvm-link> attempts to load the input files from the current directory. If 18 that fails, it looks for each file in each of the directories specified by the 19 B<-L> options on the command line. The library search paths are global; each 20 one is searched for every input file if necessary. The directories are searched 21 in the order they were specified on the command line. 22 23 =head1 OPTIONS 24 25 =over 26 27 =item B<-L> F<directory> 28 29 Add the specified F<directory> to the library search path. When looking for 30 libraries, B<llvm-link> will look in path name for libraries. This option can be 31 specified multiple times; B<llvm-link> will search inside these directories in 32 the order in which they were specified on the command line. 33 34 =item B<-f> 35 36 Enable binary output on terminals. Normally, B<llvm-link> will refuse to 37 write raw bitcode output if the output stream is a terminal. With this option, 38 B<llvm-link> will write raw bitcode regardless of the output device. 39 40 =item B<-o> F<filename> 41 42 Specify the output file name. If F<filename> is C<->, then B<llvm-link> will 43 write its output to standard output. 44 45 =item B<-S> 46 47 Write output in LLVM intermediate language (instead of bitcode). 48 49 =item B<-d> 50 51 If specified, B<llvm-link> prints a human-readable version of the output 52 bitcode file to standard error. 53 54 =item B<-help> 55 56 Print a summary of command line options. 57 58 =item B<-v> 59 60 Verbose mode. Print information about what B<llvm-link> is doing. This 61 typically includes a message for each bitcode file linked in and for each 62 library found. 63 64 =back 65 66 =head1 EXIT STATUS 67 68 If B<llvm-link> succeeds, it will exit with 0. Otherwise, if an error 69 occurs, it will exit with a non-zero value. 70 71 =head1 SEE ALSO 72 73 L<gccld|gccld> 74 75 =head1 AUTHORS 76 77 Maintained by the LLVM Team (L<http://llvm.org/>). 78 79 =cut 80
