--- Comment #7 from Alexandre Oliva <aoliva at gcc dot gnu.org> --- I've just tried and failed to duplicate this with r16-1756. ../configure -C armv7a-linux-gnueabihf --with-arch=armv7-a --with-float=hard --with-fpu=vfpv3-d16 --enable-bootstrap --prefix=$HOME/arm-linux-gnueabihf --enable-languages=ada,c,c++ --with-build-config="bootstrap-lto bootstrap-O3" && make -j8 profiledbootstrap using a previously-bootstrapped armv7a-linux-gnueabihf toolchain. Do I need different configure flags, or perhaps a different CPU count or whatever?
