无法在 armeabi-v7a 中隐藏导出

Question

这是我的 CMakeLists.txt:

cmake_minimum_required(VERSION 3.4.1)

set(CMAKE_SYSTEM_PROCESSOR arm)

set(CMAKE_C_FLAGS_RELEASE "${CMAKE_C_FLAGS_RELEASE} -s")
set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -s")

set(sources ...)
set(includes ...)
add_library(mylib SHARED ${sources})
include_directories(${includes})
find_library(log-lib log )
target_link_libraries(test ${log-lib} )

当我编译时，我的库已成功构建，而当我运行 file 时，它说库已被删除。我为全局变量使用了以下属性：

__attribute__((visibility("hidden"))

但这似乎并不影响armeabi-v7a。我仍然在 armeabi-v7a 的库导出符号 table 中看到它们。我能做些什么来隐藏它吗？

This looks like the same issue as https://bugs.llvm.org/show_bug.cgi?id=39413 / #829. -Oz turns on the GlobalMerge optimization, which isn't preserving the visibility attributes on variables.

Adding -mno-global-merge to the cflags is a workaround
