Message : Revert "Reland "Add more test_utils functions."" This reverts commit 7923e234bc458eda5936b8cb4f09fa19e28c0452. Reason for revert: Fails compilation on rollers: [2097/6048] SOLINK ./lib_angle_unittests__library.cr.so FAILED: lib_angle_unittests__library.cr.so lib_angle_unittests__library.cr.so.TOC lib.unstripped/lib_angle_unittests__library.cr.so python "../../build/toolchain/gcc_solink_wrapper.py" --readelf="../../third_party/android_ndk/toolch...(too long) ld.lld: error: undefined symbol: glCreateShader >>> referenced by shader_utils.cpp >>> angle_util_static/shader_utils.o:(CompileShader(unsigned int, char const*)) in archive obj/third_party/angle/libangle_util_static.a ld.lld: error: undefined symbol: glShaderSource Original change's description: > Reland "Add more test_utils functions." > > This is a reland of 5fcfcea4a9379633a83a67fc1d94938cb31f2a9c > > Re-land uses static linking with angle_util.
