   4 This is a parameterized header. It's supposed/ok to be included multiple times.
   5
   6 Input defines: (those to be defined by the includer file)
   7
   8 Required:
   9 DECL_OFFSET(struct,field)
  10 DECL_OFFSET2(struct,field,offset)
  11 DECL_ALIGN2(name,alignment)
  12
  13 Optional:
  14 USE_CROSS_COMPILE_OFFSETS - if defined, force the cross compiler offsets to be used, otherwise
  15         they will only be used if MONO_CROSS_COMPILE is defined
  16 DISABLE_METADATA_OFFSETS - Disable the definition of offsets for structures defined in metadata/.
  17 DISABLE_JIT_OFFSETS - Disable the definition of offsets for structures defined in mini/.
  18
  19 The last two are needed because metadata shouldn't include JIT offsets since the structures
  20 are not defined, while the JIT shouldn't include metadata offsets, since some of them
  21 are GC specific, and the JIT needs to remain GC agnostic.
  22
  23 Output defines:
  24
  25 HAS_CROSS_COMPILER_OFFSETS - if set, it means we found some cross offsets, it doesnt mean we'll use it.
  26 USED_CROSS_COMPILER_OFFSETS - if set, it means we used the cross offsets
  27
  28 Environment defines (from config.h and CFLAGS):
  29
  30 MONO_GENERATING_OFFSETS - Set by an offsets generating tool to disable the usage of any (possibly non-existing) generated header.
  31 MONO_OFFSETS_FILE - Name of the header file containing the offsets to be used.
