So GCC 10 has a bug when it generates code which manipulates 64-bit integers, is that what you are saying? > GCC trunk is broken but as you've anticipated 9 is working (just > finished an Emacs bootstrap). Thanks, this is good to know. I think we should add an entry to etc/PROBLEMS about this. Does the buggy behavior of GCC 10 happen regardless of optimization level? > This evening I'll open a bug on the GCC bugzilla and link it here. > Would be nice to fix it before the end of stage4... :/ Thanks.
