When LOCAL_LABEL_DOLLARS is defined labels of the 33 form `10$:' are expected. When LOCAL_LABEL_FB is defined labels of 34 the form `n:' are expected. The latter are expected to be referred 35 to using `nf' for a forward reference of `nb' for a backward 36 reference. 37 38 The local labels expected by the TI tools are of the form `$n:', 39 where the colon is optional. Now the $ character is considered to 40 be valid symbol name character, so gas doesn't recognise our local 41 symbols by default. Defining LEX_DOLLAR to be 1 means that gas 42 won't allow labels starting with $ and thus the hook 43 tc_unrecognized_line() will be called from read.c. We can thus 44 parse lines starting with $n as having local labels. 45 46 The other problem is the forward reference of local labels. If a 47 symbol is undefined, symbol_make() calls the md_undefined_symbol() 48 hook where we create a local label if recognised. */ 49 50/* Don't stick labels starting with 'L' into symbol table of COFF file. */ 51#define LOCAL_LABEL(name) ((name)[0] == '$' || (name)[0] == 'L') 52 53#define TARGET_BYTES_BIG_ENDIAN 0 54#define OCTETS_PER_BYTE_POWER 2 55 56#define TARGET_ARCH bfd_arch_tic4x 57 58#define TIC_NOP_OPCODE 0x0c800000 59 60#define reloc_type int 61 62#define NO_RELOC 0 63 64/* '||' denotes parallel instruction */ 65#define DOUBLEBAR_PARALLEL 1 66 67/* Labels are not required to have a colon for a suffix. */ 68#define LABELS_WITHOUT_COLONS 1 69 70/* Use $ as the section program counter (SPC). */ 71#define DOLLAR_DOT 72 73/* Accept numbers with a suffix, e.g. 0ffffh, 1010b. */ 74#define NUMBERS_WITH_SUFFIX 1 75 76extern int tic4x_unrecognized_line (int); 77#define tc_unrecognized_line(c) tic4x_unrecognized_line (c) 78 79#define md_number_to_chars number_to_chars_littleendian 80 81extern int tic4x_do_align (int, const char *, int, int); 82#define md_do_align(n,fill,len,max,label) if( tic4x_do_align (n,fill,len,max) ) goto label; 83 84/* Start of line hook to remove parallel instruction operator || */ 85extern void tic4x_start_line (void); 86#define md_start_line_hook() tic4x_start_line() 87 88extern void tic4x_cleanup (void); 89#define md_cleanup() tic4x_cleanup() 90 91extern void tic4x_end (void); 92#define md_end() tic4x_end() 93 94
