24 /* By convention, you should define this macro in the `.h' file. For
25 example, `tc-m68k.h' defines `TC_M68K'. You might have to use this
26 if it is necessary to add CPU specific code to the object format

30 /* This macro is the BFD target name to use when creating the output
31 file. This will normally depend upon the `OBJ_FMT' macro. */

34 /* This macro is the BFD architecture to pass to `bfd_set_arch_mach'. */
37 /* This macro is the BFD machine number to pass to
38 `bfd_set_arch_mach'. If it is not defined, GAS will use 0. */

41 /* You should define this macro to be non-zero if the target is big
42 endian, and zero if the target is little endian. */

45 /* If you define this macro, GAS will warn about the use of
46 nonstandard escape sequences in a string. */

50 recognized. When the function is called, `input_line_pointer'
51 will point to the start of the expression. */

54 /* This should just call either `number_to_chars_bigendian' or
55 `number_to_chars_littleendian', whichever is appropriate. On
56 targets like the MIPS which support options to change the
57 endianness, which function to call is a runtime decision. On
58 other targets, `md_number_to_chars' can be a simple macro. */

66 If `WORKING_DOT_WORD' is defined, GAS will not do broken word
67 processing (*note Broken words::.). Otherwise, you should set
68 `md_short_jump_size' to the size of a short jump (a jump that is
69 just long enough to jump around a long jmp) and
70 `md_long_jump_size' to the size of a long jump (a jump that can go
71 anywhere in the function), You should define
72 `md_create_short_jump' to create a short jump around a long jump,
73 and define `md_create_long_jump' to create a long jump. */

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

98 would print `12 34 56 78'. The default value is 4. */

105 use this macro to set P2VAR to the alignment that a request for
106 SIZE bytes will have. The alignment is expressed as a power of
107 two. If no alignment should take place, the macro definition
108 should do nothing. Some targets define a `.bss' directive that is
109 also affected by this macro. The default definition will set
110 P2VAR to the truncated power of two of sizes up to eight bytes. */
