+ * syms.c (bfd_decode_symclass)
+ Two new class characters were added - 'V' and 'v'. The
+ meaning of 'W' is now restricted to just weak non-object
+ symbols. This allows differentiation between, for example,
+ weak functions vs weak objects. nm for example now dumps:
+ 'W' = weak global
+ 'w' = weak unresolved
+ 'V' = weak global object
+ 'v' = weak unresolved object
+
+ (bfd_is_undefined_symclass): New function. Return true if the
+ given symbol class represents and undefined/unresolved symbol.
+
+ (bfd_symbol_info): Use bfd_is_undefined_symclass to check for
+ unresolved symbols.
+ * bfd-in2.h: Add prototype for bfd_is_undefined_symbol().
+
* elf32-arm.h (elf32_arm_get_symbol_type): If a symbol has the
STT_ARM_16BIT flag set, but it is not attached to a data object
return STT_ARM_16BIT so that it will be treated as code by the
int
