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?
I’m on Unbunto 9.3:
dotty version 96c (09-24-96)
lefty version 10 Mar 2005
graphviz version 2.20.2 (Mon Mar 30 10:11:53 UTC 2009)
