[Wayland-bugs] [Bug 94602] Tests fail to build when build with LTO on gcc 5.3.0

--- Comment #1 from Pekka Paalanen <ppaalanen at gmail.com> ---
I'd guess -flto is throwing away the special section where we collect the test
headers. The section is used to avoid having to create a master list of all
tests in addition to writing the tests.

Is there a way to mark that section to not be deleted by LTO?

We rely on the compiler to automatically generate __start_test_section and
__stop_test_section when putting things into the section.

Gains size? You mean it's bigger with LTO?
