Subject: 	* valarith.c (value_x_unop): Use builtin_type_int8 as type for
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=c56324e00105ce40f440d2b8052764b282cd1074;p=deliverable%2Fbinutils-gdb.git

	* valarith.c (value_x_unop): Use builtin_type_int8 as type for
	UNOP_POSTINCREMENT/UNOP_POSTDECREMENT constant 0 argument.
	(value_bit_index): Use extract_unsigned_integer
	instead of unpack_long to read single byte.
