2019-06-26RISC-V: Make objdump disassembly work right for binary files.Jim Wilson1-1/+5
Without the ELF header to set info->endian, it ends up as BFD_UNKNOWN_ENDIAN which gets printed as big-endian. But RISC-V instructions are always little endian, so we can set endian_code correctly, and then set display_endian from that. This is similar to how the aarch64 support works, but without the support for constant pools, as we don't have that on RISC-V. opcodes/ PR binutils/24739 * riscv-dis.c (riscv_disasemble_insn): Set info->endian_code. Set info->display_endian to info->endian_code.

2018-12-06opcodes/riscv: Hide '.L0 ' fake symbolsAndrew Burgess1-0/+17
The RISC-V assembler generates fake labels with the name '.L0 ' as part of the debug information (see gas/config/tc-riscv.h:FAKE_LABEL_NAME). The problem is that currently, when disassembling an object file, the output looks like this (this is an example from the GDB testsuite, but is pretty representative of anything with debug information): 000000000000001e <main>: 1e: 7179 addi sp,sp,-48 20: f406 sd ra,40(sp) 22: f022 sd s0,32(sp) 24: 1800 addi s0,sp,48 0000000000000026 <.L0 >: 26: 87aa mv a5,a0 28: feb43023 sd a1,-32(s0) 2c: fcc43c23 sd a2,-40(s0) 30: fef42623 sw a5,-20(s0) 0000000000000034 <.L0 >: 34: fec42783 lw a5,-20(s0) 38: 0007871b sext.w a4,a5 3c: 678d lui a5,0x3 3e: 03978793 addi a5,a5,57 # 3039 <.LASF30+0x2a9d> 42: 02f71463 bne a4,a5,6a <.L0 > 0000000000000046 <.L0 >: 46: 000007b7 lui a5,0x0 4a: 0007b783 ld a5,0(a5) # 0 <need_malloc> 4e: 6f9c ld a5,24(a5) 0000000000000050 <.L0 >: 50: 86be mv a3,a5 52: 466d li a2,27 54: 4585 li a1,1 56: 000007b7 lui a5,0x0 5a: 00078513 mv a0,a5 5e: 00000097 auipc ra,0x0 62: 000080e7 jalr ra # 5e <.L0 +0xe> 0000000000000066 <.L0 >: 66: 4785 li a5,1 68: a869 j 102 <.L0 > 000000000000006a <.L0 >: 6a: 000007b7 lui a5,0x0 6e: 00078513 mv a0,a5 72: 00000097 auipc ra,0x0 76: 000080e7 jalr ra # 72 <.L0 +0x8> The frequent repeated '.L0 ' labels are pointless, as they are non-unique there's no way to match a use of '.L0 ' to its appearence in the output, so we'd be better off just not printing it at all.

2016-12-20Re-work RISC-V gas flags: now we just support -mabi and -marchAndrew Waterman1-2/+6
We've decided to standardize on two flags for RISC-V: "-march" sets the target architecture (which determines which instructions can be generated), and "-mabi" sets the target ABI. We needed to rework this because the old flag set didn't support soft-float or single-float ABIs, and didn't support an x32-style ABI on RISC-V. Additionally, we've changed the behavior of the -march flag: it's now a lot stricter and only parses things we can actually understand. Additionally, it's now lowercase-only: the rationale is that while the RISC-V ISA manual specifies that ISA strings are case-insensitive, in Linux-land things are usually case-sensitive. Since this flag can be used to determine library paths, we didn't want to bake some case-insensitivity in there that would case trouble later. This patch implements these two new flags and removes the old flags that could conflict with these. There wasn't a RISC-V release before, so we want to just support a clean flag set. include/ * elf/riscv.h (EF_RISCV_SOFT_FLOAT): Don't define. (EF_RISCV_FLOAT_ABI, EF_RISCV_FLOAT_ABI_SOFT): Define.
