With the following defconfig: BR2_s390x=y BR2_KERNEL_HEADERS_6_12=y BR2_PACKAGE_GLIBC_KERNEL_COMPAT=y BR2_BINUTILS_VERSION_2_46_X=y BR2_BINUTILS_GPROFNG=y BR2_GCC_VERSION_16_X=y BR2_TOOLCHAIN_BUILDROOT_CXX=y BR2_TOOLCHAIN_BUILDROOT_FORTRAN=y BR2_GCC_ENABLE_OPENMP=y BR2_PACKAGE_HOST_GDB=y BR2_PACKAGE_HOST_GDB_TUI=y BR2_PACKAGE_HOST_GDB_PYTHON3=y BR2_GDB_VERSION_17=y BR2_GNU_MIRROR="https://mirrors.kernel.org/gnu/" BR2_PACKAGE_GDB=y gcc 16.2.0 fails to build with: ../../../libgcc/config/s390/_dpd_sd_to_hf.c:27:25: error: decimal floating-point not supported for this target 27 | HFtype __dpd_truncsdhf (_Decimal32); | ^~~~~~~~~~ ../../../libgcc/config/s390/_dpd_sd_to_hf.c:31:16: error: decimal floating-point not supported for this target 31 | force_convert (_Decimal32 x) | ^~~~~~~~~~ ../../../libgcc/config/s390/_dpd_hf_to_td.c:34:1: error: decimal floating-point not supported for this target 34 | _Decimal128 | ^~~~~~~~~~~ ../../../libgcc/config/s390/_dpd_sd_to_hf.c:35:18: error: decimal floating-point not supported for this target 35 | __dpd_truncsdhf (_Decimal32 x) | ^~~~~~~~~~ I haven't checked whether this is new with gcc 16.x or not, and I'm not familiar with floating point support on S390. Are you familiar with this issue? I see the same issue with gcc 16.1.0 in the autobuilders: https://autobuild.buildroot.net/results/f88/f88565af0f653df831a7fa43d2507d167fdb9d36/build-end.log But I don't seem to see any issue with gcc 15.x, so my guess is that this is a new issue with gcc 16.x. Any idea? Thanks a lot!
