* Disable optimization only in gtest.h of atexit_test.c for arm/aarch64 to keep VTT for std::__1::basic_stringstream<char, std::__1::char_traits<char>, std::__1::allocator<char> > to link with g++ compiled modules. * bionic-unit-tests source files are not affected by clang x86_64 fp128 bug so they can be compiled with clang. BUG: 25643775 Change-Id: I3da2a0de61edcdca07b7fcd73a16de9da4a1f7d6
