MASSIVELY reduce nim binary size

crunching.sh

FILE=life.nim
BINARY=life

function compile {
    nim c -d:release --passC:-ffast-math --opt:size $FILE
}

function crunch {
    strip --strip-all \
          -R .note \
          -R .comment \
          -R .eh_frame \
          -R .eh_frame_hdr \
          $BINARY
    sstrip -z $BINARY
}

function pack {
    upx --ultra-brute $BINARY
}

compile
crunch
pack

ls -l $BINARY

--ultra-brute option breaks the binary
