--- Comment #2 from Svante Signell <svante.signell at gmail dot com> --- Created attachment 52360 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=52360&action=edit Fix broken split-stack support for GNU/Hurd Hello, The attached patch defines OPTION_GLIBC_P and OPTION_GLIBC that was lost for config/gnu.h, thus enabling split-stack support for GNU/Hurd again. This problem happened with the latest commit and fixes for #104170 and as discussed in the mail thread starting with https://gcc.gnu.org/pipermail/gcc-patches/2022-January/588973.html. I'll submit both patches in this bug report to gcc-patches soon, if nobody takes this problem up here. I still need to find out why libgo is built before libatomic and why libbacktrace is not found where excpected. Thanks!
