Subject: 	* dwarf2loc.c (read_pieced_value) <DWARF_VALUE_STACK>: Correctly
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=05566b3b8548616bad5290963b097f1d30a2df9e;p=binutils-gdb.git

	* dwarf2loc.c (read_pieced_value) <DWARF_VALUE_STACK>: Correctly
	handle big-endian values.
	(dwarf2_evaluate_loc_desc) <DWARF_VALUE_STACK>: Likewise.
