| # This script is a general purpose "apply" function for the source files in LLVM |
| # It uses "find" to locate all the source files and then applies the user's |
| # command to them. As such, this command is often not used by itself much but |
| # the other find related tools (countloc.sh,llvmgrep,getsrcs.sh,userloc.sh) are |
| # all based on this script. This script defines "what is a source file" in |
| # LLVM and so should be maintained if new directories, new file extensions, |
| # etc. are used in LLVM as it progresses. |
| # |
| # Usage: |
| # llvmdo [-topdir DIR] [-dirs "DIRNAMES..."] [-code-only] PROGRAM ARGS... |
| # |
| # The -topdir option allows you to specify the llvm source root directly. If it |
| # is not specified then it will be obtained with llvm-config which must be built |
| # and in your path. |
| # |
| # The -dirs argument allows you to specify the set of directories that are |
| # searched. The default list of directories searched is: |
| # include lib tools utils runtime autoconf docs test examples projects |
| # Note that you must use quotes around the list of directory names. |
| # |
| # The -code-only option specifies that only those files that are considered |
| # "code" should be visited. HTML documentation is considered code, but things |
| # like README files, etc. are not. |
| # |
| # Finally, you simply specify whatever program you want to run against each |
| # file and the arguments to give it. The PROGRAM will be given the file name |
| # as its last argument. |
