When LOCAL_LABEL_DOLLARS is defined labels of the form `10$:' are expected. When LOCAL_LABEL_FB is defined labels of the form `n:' are expected. The latter are expected to be referred to using `nf' for a forward reference of `nb' for a backward reference. The local labels expected by the TI tools are of the form `$n:', where the colon is optional. Now the $ character is considered to be valid symbol name character, so gas doesn't recognise our local symbols by default. Defining LEX_DOLLAR to be 1 means that gas won't allow labels starting with $ and thus the hook tc_unrecognized_line() will be called from read.c. We can thus parse lines starting with $n as having local labels. The other problem is the forward reference of local labels. If a symbol is undefined, symbol_make() calls the md_undefined_symbol() hook where we create a local label if recognised. */ /* Don't stick labels starting with 'L' into symbol table of COFF file. */ #define LOCAL_LABEL(name) ((name)[0] == '$' || (name)[0] == 'L') #define TARGET_BYTES_BIG_ENDIAN 0 #define OCTETS_PER_BYTE_POWER 2 #define TARGET_ARCH bfd_arch_tic4x #define BFD_ARCH TARGET_ARCH #define TC_COUNT_RELOC(x) (x->fx_addsy) #define TC_CONS_RELOC RELOC_32 #define TC_COFF_FIX2RTYPE(fixP) tc_coff_fix2rtype (fixP) #define TC_COFF_SIZEMACHDEP(frag) tc_coff_sizemachdep (frag) #define NEED_FX_R_TYPE #define TIC_NOP_OPCODE 0x0c800000 #define reloc_type int #define NO_RELOC 0 /* '||' denotes parallel instruction */ #define DOUBLEBAR_PARALLEL 1 /* Labels are not required to have a colon for a suffix. */ #define LABELS_WITHOUT_COLONS 1 /* Use $ as the section program counter (SPC). */ #define DOLLAR_DOT /* Accept numbers with a suffix, e.g. 0ffffh, 1010b. */ #define NUMBERS_WITH_SUFFIX 1 extern int tic4x_unrecognized_line PARAMS ((int)); #define tc_unrecognized_line(c) tic4x_unrecognized_line (c) #define md_number_to_chars number_to_chars_littleendian extern int tic4x_do_align PARAMS ((int, const char *, int, int)); #define md_do_align(n,fill,len,max,label) if( tic4x_do_align (n,fill,len,max) ) goto label; /* Start of line hook to remove parallel instruction operator || */ extern void tic4x_start_line PARAMS ((void)); #define md_start_line_hook() tic4x_start_line() extern void tic4x_cleanup PARAMS ((void)); #define md_cleanup() tic4x_cleanup() extern void tic4x_end PARAMS ((void)); #define md_end() tic4x_end()
