As such, this command is often not used by itself much but # the other find related tools (countloc.sh,llvmgrep,getsrcs.sh) are all based # on the implementation. 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 [-dirs "DIRNAMES..." PROGRAM ARGS... # # The -dirs argument allows you to specify the set of directories that are # searched. By default, everything is searched # (excluding certain things), runs "wc -l" on them to get the number of lines in # each file and then sums up and prints the total with awk. # # The script takes no arguments but does expect to be run from the top llvm # source directory. # # This script is # greps. if test $# -lt 1 ; then echo "Usage: llvmdo [-dirs "DIRNAMES..."] PROGRAM ARGS..."; exit 1; fi if test "$1" = "-dirs" ; then LLVMDO_DIRS="$2"; shift ; shift elif test -z "$LLVMDO_DIRS" ; then LLVMDO_DIRS="include lib tools utils runtime autoconf docs test examples projects" fi PROGRAM=`which $1` if test ! -x "$PROGRAM" ; then echo "Can't execute $1" exit 1 fi shift; ARGS="$*" TOPDIR=`pwd | sed -e 's#\(.*/llvm\).*#\1#'` if test -d "$TOPDIR" ; then cd $TOPDIR find $LLVMDO_DIRS -type f \ \( \ -path 'docs/doxygen/*' -o \ -path 'docs/CommandGuide/html/*' -o \ -path 'docs/CommandGuide/man/*' -o \ -path 'docs/CommandGuide/ps/*' -o \ -path 'docs/CommandGuide/man/*' -o \ -path 'docs/HistoricalNotes/*' -o \ -path 'utils/Burg/*' -o \ -path 'docs/img/*' -o \ -path '*/.libs/*' \ \) -prune -o \( \ \( \ -name '*.cpp' -o \ -name '*.h' -o \ -name '*.def' -o \ -name '*.c' -o \ -name '*.l' -o \ -name '*.y' -o \ -name '*.td' -o \ -name '*.py' -o \ -name '*.pl' -o \ -name '*.sh' -o \ -name '*.lst' -o \ -name '*.pod' -o \ -name '*.html' -o \ -name '*.css' -o \ -name '*.cfg' -o \ -name '*.cc' -o \ -name '*.txt' -o \ -name '*.TXT' -o \ -name '*.el' -o \ -name '*.m4' -o \ -name '*.in' -o \ -name '*.ac' -o \ -name '*.tr' -o \ -name '*.vim' -o \ -name '*.gnuplot' -o \ -name 'Make*' -o \ -path 'test/*.ll' -o \ -path 'runtime/*.ll' \ \) \ \! -name '.*' \ \! -name '*~' \ \! -name '#*' \ \! -name 'Sparc.burm.c' \ \! -name 'llvmAsmParser.cpp' \ \! -name 'llvmAsmParser.h' \ \! -name 'FileParser.cpp' \ \! -name 'FileParser.h' \ \! -name 'StackerParser.h' \ \! -name 'StackerParser.cpp' \ -exec $PROGRAM $ARGS {} \; \ \) else echo "Can't find LLVM top directory in $TOPDIR" fi
