Subject: Skip if size of bfd_vma is smaller than address size
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c0f92bf9430546707f2154b8a2656974e5c7093c;p=binutils-gdb.git

Skip if size of bfd_vma is smaller than address size

Disassembler won't work properly when size of bfd_vma is smaller than
address size.

	PR binutils/19983
	PR binutils/19984
	* i386-dis.c (print_insn): Return -1 if size of bfd_vma is
	smaller than address size.
