2020-09-09power10 on ppc32Alan Modra1-1/+2
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.

2020-09-08MSP430: Support relocations for subtract expressions in .uleb128 directivesJozef Lawrynowicz1-1/+53
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 Coplan1-0/+1
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.
