I build GCC with -mcmodel=extreme in BOOT_CFLAGS, but I haven't
reproduced the problem you mentioned.
$../configure --host=loongarch64-linux-gnu
--target=loongarch64-linux-gnu --build=loongarch64-linux-gnu \
--with-arch=loongarch64 --with-abi=lp64d --enable-tls
--enable-languages=c,c++,fortran,lto --enable-plugin \
--disable-multilib --disable-host-shared --enable-bootstrap
--enable-checking=release
$ make BOOT_FLAGS="-mcmodel=extreme"
What did I do wrong?:-(
