For example, `tc-m68k.h' defines `TC_M68K'. You might have to use this if it is necessary to add CPU specific code to the object format file. */ #define TARGET_FORMAT "elf32-msp430" /* This macro is the BFD target name to use when creating the output file. This will normally depend upon the `OBJ_FMT' macro. */ #define TARGET_ARCH bfd_arch_msp430 /* This macro is the BFD architecture to pass to `bfd_set_arch_mach'. */ #define TARGET_MACH 0 /* This macro is the BFD machine number to pass to `bfd_set_arch_mach'. If it is not defined, GAS will use 0. */ #define TARGET_BYTES_BIG_ENDIAN 0 /* You should define this macro to be non-zero if the target is big endian, and zero if the target is little endian. */ #define ONLY_STANDARD_ESCAPES /* If you define this macro, GAS will warn about the use of nonstandard escape sequences in a string. */ #define md_operand(x) /* GAS will call this function for any expression that can not be recognized. When the function is called, `input_line_pointer' will point to the start of the expression. */ #define md_number_to_chars number_to_chars_littleendian /* This should just call either `number_to_chars_bigendian' or `number_to_chars_littleendian', whichever is appropriate. On targets like the MIPS which support options to change the endianness, which function to call is a runtime decision. On other targets, `md_number_to_chars' can be a simple macro. */ #define WORKING_DOT_WORD /* `md_short_jump_size' `md_long_jump_size' `md_create_short_jump' `md_create_long_jump' If `WORKING_DOT_WORD' is defined, GAS will not do broken word processing (*note Broken words::.). Otherwise, you should set `md_short_jump_size' to the size of a short jump (a jump that is just long enough to jump around a long jmp) and `md_long_jump_size' to the size of a long jump (a jump that can go anywhere in the function), You should define `md_create_short_jump' to create a short jump around a long jump, and define `md_create_long_jump' to create a long jump. */ #define MD_APPLY_FIX3 #define TC_HANDLES_FX_DONE #undef RELOC_EXPANSION_POSSIBLE /* If you define this macro, it means that `tc_gen_reloc' may return multiple relocation entries for a single fixup. In this case, the return value of `tc_gen_reloc' is a pointer to a null terminated array. */ #define MD_PCREL_FROM_SECTION(FIXP, SEC) md_pcrel_from_section(FIXP, SEC) /* If you define this macro, it should return the offset between the address of a PC relative fixup and the position from which the PC relative adjustment should be made.

This affects the way the bytes are clumped together in the listing. For example, a value of 2 might print `1234 5678' where a value of 1 would print `12 34 56 78'.

The alignment is expressed as a power of two. If no alignment should take place, the macro definition should do nothing. Some targets define a `.bss' directive that is also affected by this macro. The default definition will set P2VAR to the truncated power of two of sizes up to eight bytes. */ #define md_relax_frag(SEG, FRAGP, STRETCH) \ msp430_relax_frag (SEG, FRAGP, STRETCH) extern long msp430_relax_frag (segT, fragS *, long); #define TC_FORCE_RELOCATION_LOCAL(FIX) \ msp430_force_relocation_local(FIX) extern int msp430_force_relocation_local(struct fix *); extern int msp430_enable_relax; extern int msp430_enable_polys;
