--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> --- (In reply to Jim Wilson from comment #2) > I can reproduce. Reproducing requires enabling rtl checking which is not on > by default. I suspect that there are other similar problems, as we probably > haven't tested a build with rtl checking enabled before. Sure, I did that too: ../configure --enable-languages=c,c++ --disable-nls --enable-checking=yes,rtl,df,extra --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --target=riscv64-linux-gnu --with-ld=/usr/bin/riscv64-linux-gnu-ld --with-as=/usr/bin/riscv64-linux-gnu-as --disable-multilib --disable-libstdcxx-pch Still, for whatever reason it hasn't been called that way at all for me. BTW, rtl checking (unlike df checking and even much more so fold or valgrind checking) isn't that expensive and I use it daily for x86_64/i686-linux bootstraps, so certainly it doesn't hurt to use it for full bootstrap once a month or so.
