This patch enable perf jitdump for riscv64 and it tested with v8 on qemu rv64.
Qemu rv64:
# perf record -e cpu-clock -c 1000 -g -k mono ./d8_rv64 --perf-prof --no-wr
ite-protect-code-memory test.js
# perf inject -j -i perf.data -o perf.data.jitted
# perf report -i perf.data.jitted
Output:
# To display the perf.data header info, please use --header/--header-only option
s.
#
#
# Total Lost Samples: 0
#
# Samples: 87K of event 'cpu-clock'
# Event count (approx.): 87974000
#
# Children Self Command Shared Object Symbol
