llvm-6502/utils/countloc.sh
Reid Spencer ca7592a1ba Make all tools that use llvmdo have a -topdir option that allows the top
source dir for LLVM to be specified explicitly. This removes the dependency
on the llvm-config script. If the option is not given, then the scripts use
llvm-config which should be both built and in the PATH. This arrangement
provides a useful default for most developers but also allows the nightly
tester to execute countloc.sh before llvm-config is built and without
altering the PATH.

# This script finds all the source code files in the source code directories
# (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 one optional option, -topdir, which specifies the top llvm
# source directory. If it is not specified then the llvm-config tool is
# consulted to find top source dir.
#
# Note that the implementation is based on llvmdo. See that script for more
# details.
