#define TC_MSP430
/*   By convention, you should define this macro in the `.h' file.  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.  */

     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.  */

     address of a PC relative fixup and the position from which the PC
     relative adjustment should be made.  On many processors, the base
     of a PC relative instruction is the next instruction, so this
     macro would return the length of an instruction.  */

/*   The number of bytes to put into a word in a listing.  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 default value is 4.  */

     use this macro to set P2VAR to the alignment that a request for
     SIZE bytes will have.  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.  */
