This is very strange: I just installed the snapshot onto the big-endian mips machine that I use to generate the snapshot. This machine is the one that does generate daily testsuite results for mips-linux. I just tested a compiler cycle (with DEBUG=1) starting from this snapshot binary, and it seems to be able to generate a vanilla trunk ppcmips: ppcmips -iDW 2012/11/21 2.7.1-r1:23032 Is this a Qemu problem?
