usage="Usage: $(basename "$0") filename [options]
Description: script to automatically apply preprocessing based on file extension
and then call ajs with output file set to filename_optimised.asm.
All options are passed onto ajs (in particular the output file can be overriden).
The options for ajs are as follows:
"

FILE=$1
if [ -z "$MPIR_ROOT" ]
then
  MPIR_ROOT=../mpir
  echo "Using $MPIR_ROOT as base directory of MPIR"
fi
OUT_DIR=out

if [ "$FILE" == "--help" ] || [ "$FILE" == "" ]
then
	echo "$usage"
	./ajs --help
	exit
fi

filename=$(basename "$FILE")
filename="${filename%.*}"
echo "optimising $FILE"
mkdir -p "$OUT_DIR"
if [[ "$FILE" == *.asm ]]
then
	m4 "-I$MPIR_ROOT/mpn/" "$FILE" | ./ajs -c 0 -o "$OUT_DIR/$filename"_optimised.asm "${@:2}"
elif [[ "$FILE" == *.as ]]
then
	"$MPIR_ROOT/yasm/yasm" -e "-I$MPIR_ROOT/mpn/x86_64w/" "$MPIR_ROOT/mpn/$FILE" | ./ajs -i -c 0 -o "$OUT_DIR/$filename"_optimised.asm "${@:2}"
