# This script is a general purpose "apply" function for the source files in LLVM
12
# It uses "find" to locate all the source files and then applies the user's
13
# command to them. As such, this command is often not used by itself much but
14
# the other find related tools (countloc.sh,llvmgrep,getsrcs.sh,userloc.sh) are
15
# all based on this script. This script defines "what is a source file" in
16
# LLVM and so should be maintained if new directories, new file extensions,
17
# etc. are used in LLVM as it progresses.
20
# llvmdo [-topdir DIR] [-dirs "DIRNAMES..."] [-code-only] PROGRAM ARGS...
22
# The -topdir option allows you to specify the llvm source root directly. If it
23
# is not specified then it will be obtained with llvm-config which must be built
26
# The -dirs argument allows you to specify the set of directories that are
27
# searched. The default list of directories searched is:
28
# include lib tools utils runtime autoconf docs test examples projects
29
# Note that you must use quotes around the list of directory names.
31
# The -code-only option specifies that only those files that are considered
32
# "code" should be visited. HTML documentation is considered code, but things
33
# like README files, etc. are not.
35
# Finally, you simply specify whatever program you want to run against each
36
# file and the arguments to give it. The PROGRAM will be given the file name
37
# as its last argument.
