typedef unsigned HOST_WIDEST_FAST_INT HARD_REG_ELT_TYPE

Define the type of a set of hard registers.

HARD_REG_ELT_TYPE is a typedef of the unsigned integral type which
   will be used for hard reg sets, either alone or in an array.

   If HARD_REG_SET is a macro, its definition is HARD_REG_ELT_TYPE,
   and it has enough bits to represent all the target machine's hard
   registers.  Otherwise, it is a typedef for a suitably sized array
   of HARD_REG_ELT_TYPEs.  HARD_REG_SET_LONGS is defined as how many.

   Note that lots of code assumes that the first part of a regset is
   the same format as a HARD_REG_SET.  To help make sure this is true,
   we only try the widest fast integer mode (HOST_WIDEST_FAST_INT)
   instead of all the smaller types.  This approach loses only if
   there are very few registers and then only in the few cases where
   we have an array of HARD_REG_SETs, so it needn't be as complex as
   it used to be.

char global_regs[FIRST_PSEUDO_REGISTER]

Define some standard sets of registers.

Indexed by hard register number, contains 1 for registers
   that are being used for global register decls.
   These must be exempt from ordinary flow analysis
   and are also considered fixed.
