--- Comment #9 from tt_1 <herrtimson at yahoo dot de> --- So, I did a little bit of research. pr92807 has indeed been backported to the gcc-10 branch and is included in the gcc-10.3.0 release - it touches gcc/config/i386/i386.c and adds a testcase. There is another fixup on top of that, which is the real fix the here reported ICE: https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=74dc179a6da33cd00f6d4a93fbb97dc84f610126 or r11-209-g74dc179a6da33cd00f6d4a93fbb97dc84f610126 , to which you pointed me as the most likely fix. But that fixup (commited by Vladimir Makarov) doesn't have any bug number in the description. I wrote him an email, maybe he will comment here later. Hint: its not an option to upgrade to gcc-11.2.0, since the cross compile bootstrap is fundamentally broken by missing fenv header in the gcc-11 branch. Mixing up host and target compiler versions is nothing to desire, its a place where there will be dragons.
