+/* The following functions allow fixup chains to be stored, retrieved,
+ and swapped. They are a generalization of a pre-existing scheme
+ for storing, restoring and swapping fixup chains that was used by
+ the m32r port. The functionality is essentially the same, only
+ instead of only being able to store a single fixup chain, an entire
+ array of fixup chains can be stored. It is the user's responsibility
+ to keep track of how many fixup chains have been stored and which
+ elements of the array they are in.
+
+ The algorithms used are the same as in the old scheme. Other than the
+ "array-ness" of the whole thing, the functionality is identical to the
+ old scheme.
+
+ gas_cgen_initialize_saved_fixups_array():
+ Sets num_fixups_in_chain to 0 for each element. Call this from
+ md_begin() if you plan to use these functions and you want the
+ fixup count in each element to be set to 0 initially. This is
+ not necessary, but it's included just in case. It performs
+ the same function for each element in the array of fixup chains
+ that gas_init_parse() performs for the current fixups.
+
+ gas_cgen_save_fixups (element):
+ element - element number of the array you wish to store the fixups
+ to. No mechanism is built in for tracking what element
+ was last stored to.
+
+ gas_cgen_restore_fixups (element):
+ element - element number of the array you wish to restore the fixups
+ from.
+
+ gas_cgen_swap_fixups(int element):
+ element - swap the current fixups with those in this element number.
