[PATCH v6 5/7] perf annotate: Show raw form for jump instruction with indirect target

From: Ravi Bangoria <hidden>
Date: 2016-08-19 13:03:24
Also in: linuxppc-dev
Subsystem: performance events subsystem, the rest · Maintainers: Peter Zijlstra, Ingo Molnar, Arnaldo Carvalho de Melo, Namhyung Kim, Linus Torvalds

For jump instructions that does not include target address as direct
operand, use raw value for that. This is needed for certain powerpc
jump instructions that use target address in a register (such as bctr,
btar, ...).
