Toolchain failed to bootstrap with LP64F and LP64S ABIs.
As reported by Julien in [1]:
Testing the "lp64f" ABI with commands:
cat >.config <<EOF
BR2_loongarch64=y
BR2_LOONGARCH_FPU_32=y
BR2_LINUX_KERNEL=y
BR2_LINUX_KERNEL_USE_ARCH_DEFAULT_CONFIG=y
BR2_LINUX_KERNEL_NEEDS_HOST_OPENSSL=y
BR2_LINUX_KERNEL_NEEDS_HOST_LIBELF=y
BR2_TARGET_ROOTFS_EXT2=y
# BR2_TARGET_ROOTFS_TAR is not set
EOF
make olddefconfig
make
fails in host-gcc-initial with output:
Assembler messages:
/tmp/ccEkwSsD.s:28: Error: register save offset not a multiple of 8
/tmp/ccEkwSsD.s:30: Error: register save offset not a multiple of 8
/tmp/ccEkwSsD.s:50: Error: register save offset not a multiple of 8
See also autobuilder failures such as [2].
Testing the "lp46s" ABI with commands:
cat >.config <<EOF
BR2_loongarch64=y
BR2_LOONGARCH_FPU_NONE=y
BR2_LINUX_KERNEL=y
BR2_LINUX_KERNEL_USE_ARCH_DEFAULT_CONFIG=y
BR2_LINUX_KERNEL_NEEDS_HOST_OPENSSL=y
BR2_LINUX_KERNEL_NEEDS_HOST_LIBELF=y
BR2_TARGET_ROOTFS_EXT2=y
# BR2_TARGET_ROOTFS_TAR is not set
EOF
make olddefconfig
make
fails in host-gcc-final with output:

See also autobuilder failures with as [3].
This commit marks those ABIs as broken at the moment to allow time
for investigation. Also, since gcc defaults to the "lp64d" ABI which
requires a 64bit FPU is present, the BR2_LOONGARCH_FPU_32 and
BR2_LOONGARCH_FPU_NONE options also needs to be marked as broken
as well. See [4].

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
