https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D217648 Bug ID: 217648 Summary: [lld 4.0.0] WITH_LLD_IS_LD Results Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: freebsd-bugs@FreeBSD.org Reporter: shawn.webb@hardenedbsd.org Ed Maste asked me to open a bug ticket with results for WITH_LLD_IS_LD test= ing. So far, I've found two issues. 1. FreeBSD: Cross building arm64 world on amd64 fails /usr/obj/arm64.aarch64/scratch/fbsd/tmp/usr/bin/ld: error: sha512-armv8.pico:(.text+0x10C8): can't create dynamic relocation R_AARCH64_PREL64 against symbol 'OPENSSL_armcap_P' defined in armcap.pico /usr/obj/arm64.aarch64/scratch/fbsd/tmp/usr/bin/ld: error: sha256-armv8.pico:(.text+0xF48): can't create dynamic relocation R_AARCH64_PREL64 against symbol 'OPENSSL_armcap_P' defined in armcap.pico /usr/obj/arm64.aarch64/scratch/fbsd/tmp/usr/bin/ld: error: sha1-armv8.pico:(.text+0x1240): can't create dynamic relocation R_AARCH64_PREL64 against symbol 'OPENSSL_armcap_P' defined in armcap.pico 2. HardenedBSD: This problem may exist in FreeBSD, but since I can't get pa= st the OpenSSL linking error above, I can't confirm. It looks like clang/lld is trying to link with crt1 when linking the EFI loader. Even if I pass in -nostdlib and -nostartfiles, lld still tries to link with crt1: cc -target aarch64-unknown-freebsd12.0 --sysroot=3D/usr/obj/arm64.aarch64/usr/src/tmp -B/usr -O2 -pipe -DHARDENEDB= SD -DSKEIN_LOOP=3D111 -I/usr/src/sys/boot/efi/loader/../../arm64/libarm64 -msoft-float -mgeneral-regs-only -I/usr/src/sys/boot/efi/loader -I/usr/src/sys/boot/efi/loader/arch/arm64 -I/usr/src/sys/boot/efi/loader/../include -I/usr/src/sys/boot/efi/loader/../include/arm64 -I/usr/src/sys/boot/efi/loader/../../../contrib/dev/acpica/include -I/usr/src/sys/boot/efi/loader/../../.. -I/usr/src/sys/boot/efi/loader/../../i386/libi386 -I/usr/src/sys/boot/efi/loader/../../zfs -I/usr/src/sys/boot/efi/loader/../../../cddl/boot/zfs -I/usr/src/sys/boot/efi/loader/../../../crypto/skein -DEFI_ZFS_BOOT -DNO_PCI -DEFI -DSMBIOS_SERIAL_NUMBERS -DBOOT_FORTH -I/usr/src/sys/boot/efi/loader/../../ficl -I/usr/src/sys/boot/efi/loader/../../ficl/aarch64 -I/usr/src/sys/boot/efi/loader/../../fdt -I/usr/obj/arm64.aarch64/usr/src/sys/boot/efi/loader/../../fdt -DLOADER_FDT_SUPPORT -DLOADER_DISK_SUPPORT -DLOADER_GPT_SUPPORT -DLOADER_MBR_SUPPORT -I/usr/src/sys/boot/ficl -I/usr/src/sys/boot/ficl/aarc= h64 -I/usr/src/sys/boot/ficl/../common -I/usr/src/sys/boot/efi/loader/../../com= mon -ffreestanding -Wformat -msoft-float -fshort-wchar -fPIC -g -DHAVE_LIBRESSL -std=3Dgnu99 -Wsystem-headers -Werror -Wall -Wno-format-y2k -W -Wno-unused-parameter -Wstrict-prototypes -Wmissing-prototypes -Wpointer-ar= ith -Wno-uninitialized -Wno-pointer-sign -Wno-empty-body -Wno-string-plus-int -Wno-unused-const-variable -Wno-tautological-compare -Wno-unused-value -Wno-parentheses-equality -Wno-unused-function -Wno-enum-conversion -Wno-unused-local-typedef -Wno-address-of-packed-member -Qunused-arguments = -v -o loader.sym.full autoload.o bootinfo.o conf.o copy.o devicename.o main.o self_reloc.o smbios.o vers.o zfs.o skein.o skein_block.o exec.o start.o cac= he.o boot.o commands.o console.o devopen.o interp.o interp_backslash.o interp_parse.o ls.o misc.o module.o panic.o load_elf64.o reloc_elf64.o disk= .o part.o crc32.o bcache.o interp_forth.o=20 /usr/obj/arm64.aarch64/usr/src/sys/boot/efi/loader/../../ficl/libficl.a /usr/obj/arm64.aarch64/usr/src/sys/boot/efi/loader/../libefi/libefi.a /usr/obj/arm64.aarch64/usr/src/sys/boot/efi/loader/../../fdt/libfdt.a /usr/obj/arm64.aarch64/usr/src/sys/boot/efi/loader/../../efi/fdt/libefi_fdt= .a /usr/obj/arm64.aarch64/usr/src/sys/boot/efi/loader/../../../../lib/libstand= /libstand.a FreeBSD clang version 4.0.0 (branches/release_40 296509) (based on LLVM 4.0= .0) Target: aarch64-unknown-freebsd12.0 Thread model: posix InstalledDir: /usr/obj/arm64.aarch64/usr/src/tmp/usr/bin "/usr/obj/arm64.aarch64/usr/src/tmp/usr/bin/ld" --sysroot=3D/usr/obj/arm64.aarch64/usr/src/tmp --eh-frame-hdr -dynamic-link= er /libexec/ld-elf.so.1 --enable-new-dtags -o loader.sym.full /usr/obj/arm64.aarch64/usr/src/tmp/usr/lib/crt1.o /usr/obj/arm64.aarch64/usr/src/tmp/usr/lib/crti.o /usr/obj/arm64.aarch64/usr/src/tmp/usr/lib/crtbegin.o -L/usr/obj/arm64.aarch64/usr/src/tmp/usr/lib autoload.o bootinfo.o conf.o copy.o devicename.o main.o self_reloc.o smbios.o vers.o zfs.o skein.o skein_block.o exec.o start.o cache.o boot.o commands.o console.o devopen.o interp.o interp_backslash.o interp_parse.o ls.o misc.o module.o panic.o load_elf64.o reloc_elf64.o disk.o part.o crc32.o bcache.o interp_forth.o /usr/obj/arm64.aarch64/usr/src/sys/boot/efi/loader/../../ficl/libficl.a /usr/obj/arm64.aarch64/usr/src/sys/boot/efi/loader/../libefi/libefi.a /usr/obj/arm64.aarch64/usr/src/sys/boot/efi/loader/../../fdt/libfdt.a /usr/obj/arm64.aarch64/usr/src/sys/boot/efi/loader/../../efi/fdt/libefi_fdt= .a /usr/obj/arm64.aarch64/usr/src/sys/boot/efi/loader/../../../../lib/libstand= /libstand.a -lgcc --as-needed -lgcc_s --no-as-needed -lc -lgcc --as-needed -lgcc_s --no-as-needed /usr/obj/arm64.aarch64/usr/src/tmp/usr/lib/crtend.o /usr/obj/arm64.aarch64/usr/src/tmp/usr/lib/crtn.o /usr/obj/arm64.aarch64/usr/src/tmp/usr/bin/ld: error: /usr/src/sys/boot/efi/loader/arch/arm64/start.S:143: duplicate symbol '_sta= rt' /usr/obj/arm64.aarch64/usr/src/tmp/usr/bin/ld: error: /usr/src/lib/csu/aarch64/crt1.c:(.text+0x0): previous definition was here cc: error: linker command failed with exit code 1 (use -v to see invocation) *** Error code 1 Stop. make[2]: stopped in /usr/src/sys/boot/efi/loader --=20 You are receiving this mail because: You are the assignee for the bug.=
