When excluding SHF_LINK_ORDER sections that happen to have SEC_KEEP set, we need to set SEC_EXCLUDE here to avoid a problem later. * ldelf.c (ldelf_before_place_orphans): Set SEC_EXCLUDE for discarded sections. (cherry picked from commit 5987401fcbc9933808fa0d84d1b01c93356c39a1)

2021-01-28POWER10: Add Return-Oriented Programming instructionsPeter Bergner9-1/+149
POWER10 adds some return-oriented programming (ROP) instructions and this patch adds support for them. You will notice that they are enabled for POWER8 and later, not just POWER10 and later. This is on purpose. This allows the instructions to be added to POWER8 binaries that can be run on POWER8, POWER9 and POWER10 cpus. On POWER8 and POWER9, these instructions just act as nop's. opcodes/ * ppc-opc.c (insert_dw, (extract_dw): New functions. (DW, (XRC_MASK): Define.

2021-01-28R_PPC64_GOT_LO_DS and R_PPC64_GOT_HA sanity checkAlan Modra2-2/+8
The previous sanity check allowed a ld on the HA reloc and addis on the LO_DS. * elf64-ppc.c (ppc64_elf_relocate_section): Tighten sanity check on R_PPC64_GOT_LO_DS and R_PPC64_GOT_HA instructions. (cherry picked from commit fba8689ad3b72a3e895ebd41485d747dba5da811)
2021-01-28power10 on ppc32Alan Modra2-1/+9
We don't support power10 on ppc32, mainly because some instructions have 34-bit fields for which we don't have relocations on ppc32. If you try to assemble typical code, you'll see errors saying "reloc ... not supported by object file format". Also, on 32-bit hosts with binutils configured without a 64-bit bfd, you'll see errors saying "bignum invalid" when using large offsets. But let's not kill output of prefix insns entirely on 32-bit hosts. * config/tc-ppc.c (md_assemble): Emit prefix insn by parts when valueT is smaller than 64 bits.

2021-01-24DWARF-5: Ignore empty range in DWARF-5 line number tablesH.J. Lu2-3/+6
The DWARF5 spec does indeed explicitly say: "A bounded range entry whose beginning and ending address offsets are equal (including zero) indicates an empty range and may be ignored." Since arange_add already ignores empty ranges, remove the whole check which is equivalent to the check plus explicit continue.
