Hi,
I wonder if anyone ever tried valgrind in arm64-android.
I was trying valgrind to investigate malloc/free related bugs in
android-64. However, even though valgrind was successfully built, android
cannot still lunch an APP with valgrind and had the following errors:
I/ActivityManager( 2262): START u0

I/val.sh ( 3426): ==3427== Your program just tried to execute an
instruction that Valgrind
I/val.sh ( 3426): ==3427== did not recognise. There are two possible
reasons for this.
I/val.sh ( 3426): ==3427== 1. Your program has a bug and erroneously jumped
to a non-code
I/val.sh ( 3426): ==3427== location. If you are running Memcheck and you
just saw a
I/val.sh ( 3426): ==3427== warning about a bad jump, it's probably your
program's fault.
I/val.sh ( 3426): ==3427== 2. The instruction is legitimate but Valgrind
doesn't handle it,
I/val.sh ( 3426): ==3427== i.e. it's Valgrind's fault. If you think this is
the case or
I/val.sh ( 3426): ==3427== you are not sure, please let us know and we'll
try to fix it.
I/val.sh ( 3426): ==3427== Either way, Valgrind will now raise a SIGILL
signal which will
I/val.sh ( 3426): ==3427== probably kill your program.

D/AndroidRuntime( 3393): Shutting down VM
I saw aosp repo just disabled arm64 build few days ago (
https://android.googlesource.com/platform/external/valgrind/+/3eb9932390b64e5cb416086b329fea2ecfdd49f3
)
and valgrind official site does not claim that it supports arm64-android,
either.
So I'm curious that did anyone ever tried valgrind in arm64-android.
