The blc.S didn’t build for me using `-oformat:binary` . Changing to `--oformat=binary` it compiled, but then get core dumps. Running Linux x86_64 up to date Ubuntu 20.04.4 .
for cc in cc gcc clang
do echo "## $cc"
$cc -no-pie -static -nostdlib -o blc -Wl,--oformat=binary blc.S || exit 1
{ printf 0010; printf 0101; } | ./blc; echo
done
