dolphin/Tools/perf-disassemble.sh

#!/bin/bash
#
# Using this script instead of objdump enables perf to disassemble
# and annotate any JIT code (given a symbol file).
#
# To run perf without root:
#   kernel.perf_event_paranoid = -1
# To trace a process without root:
#   kernel.yama.ptrace_scope = 0
#
# Example usage:
# $ dolphin-emu -C Dolphin.Core.PerfMapDir=/tmp -b -e $game
# $ perf top -p $(pidof dolphin-emu) --objdump ./Tools/perf-disassemble.sh -M intel
