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.
