+/* Sort any unmatched HI16 and GOT16 relocs so that they immediately precede
+ the corresponding LO16 reloc. This is called before md_apply_fix3 and
+ tc_gen_reloc. Unmatched relocs can only be generated by use of explicit
+ relocation operators.
+
+ For our purposes, a %lo() expression matches a %got() or %hi()
+ expression if:
+
+ (a) it refers to the same symbol; and
+ (b) the offset applied in the %lo() expression is no lower than
+ the offset applied in the %got() or %hi().
+
+ (b) allows us to cope with code like:
+
+ lui $4,%hi(foo)
+ lh $4,%lo(foo+2)($4)
+
+ ...which is legal on RELA targets, and has a well-defined behaviour
+ if the user knows that adding 2 to "foo" will not induce a carry to
+ the high 16 bits.
+
+ When several %lo()s match a particular %got() or %hi(), we use the
+ following rules to distinguish them:
+
+ (1) %lo()s with smaller offsets are a better match than %lo()s with
+ higher offsets.
+
+ (2) %lo()s with no matching %got() or %hi() are better than those
+ that already have a matching %got() or %hi().
+
+ (3) later %lo()s are better than earlier %lo()s.
+
+ These rules are applied in order.
+
+ (1) means, among other things, that %lo()s with identical offsets are
+ chosen if they exist.
+
+ (2) means that we won't associate several high-part relocations with
+ the same low-part relocation unless there's no alternative. Having
+ several high parts for the same low part is a GNU extension; this rule
+ allows careful users to avoid it.
+
+ (3) is purely cosmetic. mips_hi_fixup_list is is in reverse order,
+ with the last high-part relocation being at the front of the list.
+ It therefore makes sense to choose the last matching low-part
+ relocation, all other things being equal. It's also easier
+ to code that way. */
