Disassembly Listing
A PMU histogram report gives a disassembly listing, which is a source listing with disassembly code for the top performance bottlenecks.
The disassembly listing is not provided by default. To see it, you must use the

Disassembly listings show instruction templates and symbolic representations of branch targets. You also have the option to include a mark (colon) before instructions that are the target of a branch instruction.
Intraprocedural branch targets are shown as:
{self}+offset
where offset is an offset from the start of the procedure.
Interprocedural branch targets within the same load module are shown as:
procedure_name+0x0
