[BUG] unwinder symbols are no longer hidden with ndk-build #1092
Description
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := foo
LOCAL_SRC_FILES := foo.cpp
LOCAL_CPPFLAGS := -fexceptions -frtti
include $(BUILD_SHARED_LIBRARY)APP_STL := c++_staticvoid foo() {
throw 42;
}$ ndk-build -C foo APP_ABI=arm64-v8a -B V=1
(build output shows -Wl,--exclude-libs,libgcc.a)
$ readelf -sW libs/arm64-v8a/libfoo.so| grep _Unwind
(shows global visibility unwind symbols)Adding -Wl,--exclude-libs,libgcc_real.a to LOCAL_LDFLAGS fixes this, so this was caused by changing libgcc.a to be a version script (r19, if memory serves).
