Subject[PATCH v7 3/6] perf annotate: Show raw form for jump instruction with indirect target
Date
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, ...).

Before:
ld r12,32088(r12)
mtctr r12
v bctr ffffffffffffca2c
std r2,24(r1)
addis r12,r2,-1

After:
ld r12,32088(r12)
mtctr r12
v bctr
std r2,24(r1)
addis r12,r2,-1
