TLS-related issues were fixed by this in the past: https://github.com/dotnet/corert/pull/8323. We either introduced a new place that needs an ifdef or something else regressed. (I'm on vacation and won't be looking at this more right now.)
Fixed in #77475.
Description
I have been experimenting with Android and NativeAOT through JNI shared libraries that are consumed by the HelloJNI application.
However with latest runtime version, opening the application closes it due to the absence of the "tls_CurrentThread" symbol into the compiled library.
My last successful experiment was on 2022 July 20th with microsoft.dotnet.ilcompiler 7.0.0-rc.1.22370.2.
The JNI library code is: https://github.com/josephmoresena/NativeAOT-AndroidHelloJniLib
The branch I use to compile NativeAOT is: https://github.com/josephmoresena/runtime/tree/android
Reproduction Steps
export NDK_VER=r21e export ANDROID_NDK_ROOT=~/android-ndk-${NDK_VER} export ANDROID_SDK_ROOT=~/android-sdk export HOST_OS=linux export RUNTIME_REPO=~/source/repos/runtime
TARGET_BUILD_ARCH=arm64 ./build.sh -s clr.nativeaotruntime+clr.nativeaotlibs+libs+mono -arch arm64 -os Android -c Release -lc Release -rc Release
Expected behavior
The android application loads an shows a text generated by NativeAOT JNI library.
Actual behavior
Application crashes and debugger shows following error:
I/xample.hellojn: Late-enabling -Xcheck:jni E/xample.hellojn: Unknown bits set in runtime_flags: 0x8000 D/tperf_getInstance: processName = com.example.hellojni unsupported!!!

Regression?
I don't know with accurrancy, latest succesfull experimente was mate on 2022 July 20th.
