Subject: [PATCH v10 0/4] perf arm-spe: Allow synthesizing of branch instructions

Currently the --itrace=b will only show branch-misses but this change
allows perf to synthesize branches as well.

The change also incorporates the ability to display the target
addresses when specifying the addr field if the instruction is a branch.

Graham Woodward (4):
  perf arm-spe: Set sample.addr to target address for instruction sample
  perf arm-spe: Use ARM_SPE_OP_BRANCH_ERET when synthesizing branches
  perf arm-spe: Correctly set sample flags
  perf arm-spe: Update --itrace help text
