If TARGET_DEFAULT is 0, it falls back to the defaults for powerpc, powerpc64, or powerpc64le.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65138 --- Comment #7 from David Edelsohn dje at gcc dot gnu.org --- Allowing users to specify -mcpu=powerpc64le is all well and good, but if TARGET_DEFAULT is set, it should not be gratuitously overridden in rs6000_option_override. The logic is not correct and defaults should not be inherited from the processor name.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65138 --- Comment #5 from Michael Meissner meissner at gcc dot gnu.org --- Ok, after figuring out that I was building on gcc2-power8.osuosl.org (the old big endian system that is going away), I checked out the current revision (221024) and rebuilt a tool chain on gcc2-2-power8.osuosl.org. I now see the error if I build without the --with-cpu=power8 option (the options I used were --prefix=xxx and --disable-multilib).

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65138 --- Comment #3 from Michael Meissner meissner at gcc dot gnu.org --- I just built a toolchain on gcc2-power8.osuosl.org with the configuration line: /home/meissner/fsf-src/trunk/configure --prefix=/home/meissner/fsf-install-ppcle64/trunk --enable-languages=c,c++,ada,fortran,java,objc,obj-c++ --with-long-double-128 --enable-secureplt --enable-__cxa_atexit --disable-libsanitizer --with-cpu=power8 And after doing a make check, install, and check, I did not see any of these tests generate errors with -flto -fuse-linker-plugin -flto-partition=none. What was the exact command line you used to configure the compiler, and what was your path?

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65138 --- Comment #4 from Markus Trippelsdorf trippels at gcc dot gnu.org --- (In reply to Michael Meissner from comment #3) I just built a toolchain on gcc2-power8.osuosl.org with the configuration line: /home/meissner/fsf-src/trunk/configure --prefix=/home/meissner/fsf-install-ppcle64/trunk --enable-languages=c,c++,ada,fortran,java,objc,obj-c++ --with-long-double-128 --enable-secureplt --enable-__cxa_atexit --disable-libsanitizer --with-cpu=power8 And after doing a make check, install, and check, I did not see any of these tests generate errors with -flto -fuse-linker-plugin -flto-partition=none. What was the exact command line you used to configure the compiler, and what was your path? It doesn't happen --with-cpu=power8. So please leave that out. I was using: ../gcc/configure --disable-bootstrap --disable-libstdcxx-pch --disable-libvtv --disable-libitm --disable-libcilkrts --disable-libssp --disable-libgomp --disable-werror --disable-multilib --enable-languages=c,c++
