+ * config/stormy16/stormy16.h (SYMBOL_FLAG_XSTORMY16_BELOW100):
+ New define.
+ (ASM_OUTPUT_LABELREF): Delete - it is no longer needed.
+ * config/stormy16/stormy16.c (xstormy16_below100_symbol):
+ Check symbol flags instead of symbol name mangling.
+ (xstormy16_asm_output_aligned_common): Likewise. Also
+ simplify code since the bss100_section cass is the only case
+ where the below100 code will be triggered.
+ (xstormy16_encode_section_info): Encode below100 attribute
+ using the SYMBOL_FLAG_XSTORMY16_BELOW100 instead of mangling
+ the name.
+ (xstormy16_strip_name_encoding): Delete - this function is no
+ longer needed.
+ (TARGET_STRIP_NAME_ENCODING): Undefine.
+ * config/stormy16/stormy16-protos.h: Delete prototype for
+ xstormy16_strip_name_encoding.
