Stop "objdump -d" from disassembling past a symbolic address.
include * dis-asm.h (struct disassemble_info): Add stop_vma field. binuti * objdump.c (disassemble_bytes): Set the stop_vma field in the disassemble_info structure when disassembling code sections with -d. * doc/binutils.texi (objdump): Document the discrepancy between -d and -D. opcodes * dis-buf.c (buffer_read_memory): Fail is stop_vma is set and the requested region lies beyond it. * bfin-dis.c (print_insn_bfin): Ignore sysop instructions when looking for 32-bit insns. * mcore-dis.c (print_insn_mcore): Disable stop_vma when reading data. * sh-dis.c (print_insn_sh): Likewise. * tic6x-dis.c (print_insn_tic6x): Disable stop_vma when reading blocks of instructions. * vax-dis.c (print_insn_vax): Check that the requested address does not clash with the stop_vma. tests * gas/arm/backslash-at.s: Add extra .byte directives so that the foo symbol does not appear to point half way through an instruction. * gas/arm/backslash-at.d: Update expected disassembly. * gas/i386/ilp32/x86-64-opcode-inval-intel.d: Likewise. * gas/i386/ilp32/x86-64-opcode-inval.d: Likewise. * gas/i386/x86-64-opcode-inval-intel.d: Likewise. * gas/i386/x86-64-opcode-inval.d: Likewise.
