Right, I assume Mark meant "if you try to use foo-gcc -m64 with a 32-bit assembler". > That said, I guess I don't have a problem with this patch. How would you feel about a patch that made us always pass --64 as appropriate, at least if the assembler in question is gas? I periodically bootstrap on a 64-bit kernel with a 32-bit root FS. But the assembler and linker are biarch, and the 64-bit libs are installed, so it's just the defaults that are wrong. If we were explicit, an x86_64-linux compiler would Just Work. Which would be nice since that's what config.guess says to build :-) -- Daniel Jacobowitz CodeSourcery, LLC
