+# 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 -P /tmp -b -e $game
+# $ perf top -p $(pidof dolphin-emu) --objdump ./Tools/perf-disassemble.sh
