--- Comment #4 from Manfred Schwarb <manfred99 at gmx dot ch> ---
This broke my i686 build (only, x86_64 build with same settings is OK), I get
configure: error: Intel CET must be enabled on Intel CET enabled host
make[2]: *** [configure-stage2-lto-plugin] Error 1
make[2]: *** Waiting for unfinished jobs....
configure: error: Intel CET must be enabled on Intel CET enabled host
make[2]: *** [configure-stage2-libiberty] Error 1
both in prev-libiberty/config.log and prev-lto-plugin/config.log there is
configure:5283: checking for CET support
configure:5312: gcc -march=i686 -m32 -Wa,--32 -c -g -fcf-protection conftest.c
>&5
gcc: error: unrecognized command line option '-fcf-protection'
configure:5312: $? = 1
configure: failed program was:

My configure command is
#> ../gcc-trunk-source/gcc/configure --enable-languages=c,c++,fortran
--enable-checking=yes,extra --disable-libstdcxx-pch --enable-libgomp
--enable-lto --enable-gold --with-plugin-ld=gold
--prefix=/usr/local/gcc-trunk-32bit i686-linux
and then I issue the make command with
#> make -j4 BOOT_CFLAGS="-g -O2" bootstrap2-lean
As mentioned above, the very same commands (without the "i686-linux" configure
argument) work fine to build x86_64 binaries.
