--- Comment #5 from Paul Floyd <pjfl...@wanadoo.fr> --- This is an LTO issue. On gccfarm gcc203 which is paulf@gcc203:~/scratch/valgrind$ lscpu Architecture: ppc64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Big Endian Then with ./configure --enable-lto=yes (from git HEAD but surely the same as the RC tarball) I get s.o ../coregrind/libcoregrind-ppc64be-linux.a ../VEX/libvex-ppc64be-linux.a -lgcc ../coregrind/libgcc-sup-ppc64be-linux.a /usr/bin/ld:
