[LLVMdev] [PBQP] Are edges between nodes from totally disjoint register classes necessary ?
Hi Lang,
While working on improving the debug dumps of the PBQP graphs, I found out
that we can have some edges between nodes which belong to totally disjoint
register classes (for example, on AArch64, this would be an int and a
floating point register). Although it is true those 2 registers interferes,
in the sense they are alive at the same time, they never have any physical
interference,
