I’m trying to debug an issue in codegen but when using:
llc -view-legalize-dags -O1 -march=x86-64 -o c-01.s c-opt.bc
I get a .dot file and while it has the DAG the nodes do not have any text. I’m probably doing something very stupid but I cannot figure what it is can anyone point out what I’m doing wrong?
Thanks,
Ben
