--- Comment #15 from Florian Weimer <fw at gcc dot gnu.org> ---
This is all very strange.
How have extended makecontext for x86 AVX2/AVX-512 support? The CPU context
needs to be stored somewhere, after all.
I find it difficult to believe that there is no space left anyway to store the
shadow stack pointer information.
