perf now passes the proper no-show-raw-insn option instead of no-show-raw.
Keep no-show-raw as a fallback for older kernels/perf-toolings.

# 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
