Upstream GRUB on RISC-V is compiled with -mcmodel=medany -fno-PIE: A first configuration test has as result: "cc1: sorry, unimplemented: code model 'large' with '-fPIC'". Later checking whether `riscv64-linux-gnu-gcc' has `-fPIC' as default results in no.
medany is meant for executables up to 2 GiB. This is why HI20 relocations can be used. Configure.ac on arm64 selects -fPIC as build argument. I wonder if for RISC-V should use the same. 1393 # Position independent executable. 1394 grub_CHECK_PIC 1395 [# On most platforms we don't want PIC as it only makes relocations harder 1396 # and code less efficient. On mips we want to have one got table per module 1397 # and reload $gp in every function. 1398 # GCC implements it using symbol __gnu_local_gp in non-PIC as well. 1399 # However with clang we need PIC for this reloading to happen. 1400 # With arm64 we need relocations that are in some way representable in 1401 # PE as we need to support arm64-efi. Without -fPIC clang generates 1402 # movk's which aren't representable. 1403 # Since default varies across dictributions use either -fPIC or -fno-PIC 1404 # explicitly. 1405 if ( test x$target_cpu = xmips || test x$target_cpu = xmipsel || test x$target_cpu = xarm64 ) && test "x$grub_cv_cc_target_clang" = xyes ; then 1406 TARGET_CFLAGS="$TARGET_CFLAGS -fPIC" 1407 elif [ x"$pic_possible" = xyes ]; then 1408 TARGET_CFLAGS="$TARGET_CFLAGS -fno-PIC" 1409 fi] -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2103864 Title: grub-efi-riscv64-bin 2.12-5ubuntu9 fails with "relocation overflow" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/2103864/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
