|
# 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.
