+ Based on patches from John W. Woznack <jwoznack@concentric.net>:
+ * itbl-ops.c (itbl_get_reg_val): Add pval parameter. Return
+ indication of success rather than a value.
+ (itbl_get_val): Likewise.
+ (itbl_get_field): Use strcspn. Change delimiters to include
+ parens.
+ * itbl-ops.h (itbl_get_reg_val): Update declaration.
+ (itbl_get_val): Likewise.
+ * config/tc-mips.c (mips_ip): Update call to itbl_get_reg_val.
+
* symbols.c (copy_symbol_attributes): Convert local symbols to
regular symbols.
