# This data is used to establish executable/library
# dependencies.  Comes from the llvm-config script, which is built and
# installed on the bin directory for MinGW or Linux. At the end of the
# script, you'll see lines like this:

# LLVMARMAsmPrinter.o: LLVMARMCodeGen.o libLLVMAsmPrinter.a libLLVMCodeGen.a libLLVMCore.a libLLVMSupport.a libLLVMTarget.a

# This is translated to:

# set(MSVC_LIB_DEPS_LLVMARMAsmPrinter LLVMARMCodeGen LLVMAsmPrinter LLVMCodeGen LLVMCore LLVMSupport LLVMTarget)

# It is necessary to remove the `lib' prefix and the `.a'.

# This 'sed' script should do the trick:
# sed -e s'#\.a##g' -e 's#libLLVM#LLVM#g' -e 's#: ##' -e 's#\(.*\)#set(MSVC_LIB_DEPS_\1)#' ~/llvm/tools/llvm-config/LibDeps.txt
#

# TODO: do this transformations on cmake.

# It is very important that the LLVM built for extracting this data
# must contain all targets, not just X86.
