--/* Zero or more C statements that may conditionally modify five variables
--   fixed_regs, call_used_regs, global_regs, reg_names, and reg_class_contents,
--   to take into account any dependence of these register sets on target flags.
--   The first three of these are of type char [] (interpreted as Boolean
--   vectors). global_regs is a const char *[], and reg_class_contents is a
--   HARD_REG_SET. Before the macro is called, fixed_regs, call_used_regs,
--   reg_class_contents, and reg_names have been initialized from
--   FIXED_REGISTERS, CALL_USED_REGISTERS, REG_CLASS_CONTENTS, and
--   REGISTER_NAMES, respectively. global_regs has been cleared, and any
--   \91-ffixed-reg\92, \91-fcall-used-reg\92 and \91-fcall-saved-reg\92 command options
--   have been applied.
--
--   You need not define this macro if it has no work to do.
--
--   If the usage of an entire class of registers depends on the target flags,
--   you may indicate this to GCC by using this macro to modify fixed_regs and
--   call_used_regs to 1 for each of the registers in the classes which should
--   not be used by GCC. Also define the macro REG_CLASS_FROM_LETTER /
--   REG_CLASS_FROM_CONSTRAINT to return NO_REGS if it is called with a letter
--   for a class that shouldn\92t be used.  (However, if this class is not included
--   in GENERAL_REGS and all of the insn patterns whose constraints permit this
--   class are controlled by target switches, then GCC will automatically avoid
--   using these registers when the target switches are opposed to them.) */
