2020-09-08MSP430: Support relocations for subtract expressions in .uleb128 directivesJozef Lawrynowicz6-7/+197
Link-time relaxations of branches are common for MSP430, given that GCC can generate pessimal branch instructions, and the -mcode-region=either/-mdata-region=either options to shuffle sections can further change the type of branch instruction required. These relaxations can result in invalid code when .uleb128 directives, used in the .gcc_except_table section, are used to calculate the distance between two labels. A value for the .uleb128 directive is calculated at assembly-time, and can't be updated at link-time, even if relaxation causes the distance between the labels to change. This patch adds relocations for subtract expressions in .uleb128 directives, to allow the linker to re-calculate the value of these expressions after relaxation has been performed. bfd/ChangeLog: * bfd-in2.h (bfd_reloc_code_real): Add BFD_RELOC_MSP430_{SET,SUB}_ULEB128. * elf32-msp430.c (msp430_elf_ignore_reloc): New.

2020-09-08aarch64: Add base support for Armv8-RAlex Coplan4-1/+14
This patch adds the basic infrastructure needed to support Armv8-R in AArch64 binutils: new command-line flags, new feature bits, a new BFD architecture, and support for differentiating between architecture variants in the disassembler. The new command-line options added by this patch are -march=armv8-r in GAS and -m aarch64:armv8-r in objdump. The disassembler support is necessary since Armv8-R AArch64 introduces a system register (VSCTLR_EL2) which shares an encoding with a different system register (TTBR0_EL2) in Armv8-A. This also allows us to use the correct preferred disassembly for the new DFB alias introduced in Armv8-R. bfd/ChangeLog: 2020-09-08 Alex Coplan <alex.coplan@arm.com> * archures.c (bfd_mach_aarch64_8R): New. * bfd-in2.h: Regenerate. * cpu-aarch64.c (bfd_aarch64_arch_v8_r): New.

2020-09-08PR26580, Size and alignment of commons vs as-needed shared libAlan Modra2-40/+46
Two pieces to this puzzle: 1) Revert HJ's fix for PR13250 so that size and alignment isn't sticky, instead attack the real underlying problem that _bfd_generic_link_add_one_symbol does the wrong thing in making a common section in a shared library bfd. 2) Save and restore common u.c.p fields, which hold the section and alignment. A better fix for (2) would be to throw away all of that horrible code saving and restoring the hash table when loading as-needed library symbols, and instead do a scan over as-needed library symbols before adding anything. bfd/ PR 13250 PR 26580 * elflink.c (_bfd_elf_merge_symbol): Make "override" a bfd**.

2020-09-04Allow plugin syms to mark as-needed shared libs neededAlan Modra2-10/+12
We must tell LTO about symbols in all shared libraries loaded. That means we can't load extra shared libraries after LTO recompilation, at least, not those that affect the set of symbols that LTO cares about, the IR symbols. This change will likely result in complaints about --as-needed libraries being loaded unnecessarily, but being correct is more important than being optimal. One of the PR15146 tests regresses, and while that could be hidden by disabling the missing dso message by making it conditional on h->root.non_ir_ref_regular, that would just be sweeping a problem under the rug. bfd/ PR 15146 PR 26314 PR 26530 * elflink.c (elf_link_add_object_symbols): Do set def_regular and ref_regular for IR symbols.

2020-09-03RISC-V: Report warnings rather than errors for the mis-matched ISA versions.Nelson Chu2-32/+51
Same as the privileged spec attributes check - different ISA versions should be compatible, unless there are some known conflicts. Therefore, we should allow to link objects with different ISA versions, and update the output ISA versions once the corresponding input ones are newer.

2020-09-03RISC-V: Improve the error message for the mis-matched ISA versions.Kito Cheng3-4/+17
Consider the updated attr-merge-arch-failed-01.d testcase. Extension A's version are mis-matched between attr-merge-arch-failed-01a.s and attr-merge-arch-failed-01b.s. But the old binutils reports that the mis-matched extension is M rather than A. This commit is used to fix the wrong mis-matched error message. Besides, when parsing the arch string in the riscv_parse_subset, it shouldn't be NULL or empty. However, it might be empty when we failed to merge the arch string in the riscv_merge_attributes. Since we should already issue the correct error message in another side, and the message - ISA string must begin with rv32 or rv64 - is meaninglesss when the arch string is empty, so do not issue it. bfd/ * elfnn-riscv.c (riscv_merge_std_ext): Fix to report the correct error message when the versions of extension are mis-matched. * elfxx-riscv.c (riscv_parse_subset): Don't issue the error when the string is empty. ld/ * testsuite/ld-riscv-elf/attr-merge-arch-failed-01.d: Updated. * testsuite/ld-riscv-elf/attr-merge-arch-failed-01a.s: Likewise. * testsuite/ld-riscv-elf/attr-merge-arch-failed-01b.s: Likewise.

In fact, we can treate these two relocation as the same one in the riscv_elf_check_relocs. I have heard that RISC-V lld had made this improvement, and so had GNU AARCH64, they only need R_AARCH64_CALL26 for calls rather than two seperate relocations. Beside, the following PLT issue for RISC-V 32-bit glibc seems to be fixed by applying at least this patch. <https://sourceware.org/pipermail/libc-alpha/2020-August/117214.html> I have ran the toolchain regression, and everything seems fine for now. bfd/ * elfnn-riscv.c (riscv_elf_check_relocs): Treat R_RISCV_CALL and R_RISCV_CALL_PLT as the same in the riscv_elf_check_relocs. (riscv_elf_relocate_section): Remove the R_RISCV_CALL for the unresolved reloc checks. ld/ testsuite/ld-riscv-elf/lib-nopic-01a.s: Use R_RISCV_JAL rather than R_RISCV_CALL. testsuite/ld-riscv-elf/lib-nopic-01b.d: Likewise. testsuite/ld-riscv-elf/lib-nopic-01b.s: Likewise.
