+   Relative pointers
+
+   Several pointer fields in info tables are expressed as offsets
+   relative to the info pointer, so that we can generate
+   position-independent code.
+
+   Note [x86-64-relative]
+   There is a complication on the x86_64 platform, where pointeres are
+   64 bits, but the tools don't support 64-bit relative relocations.
+   However, the default memory model (small) ensures that all symbols
+   have values in the lower 2Gb of the address space, so offsets all
+   fit in 32 bits.  Hence we can use 32-bit offset fields.
+
+   When going via-C, the mangler arranges that we only generate
+   relative relocations between symbols in the same segment (the text
+   segment).  The NCG, however, puts things in the right sections and
+   uses 32-bit relative offsets instead.
+
+   Somewhere between binutils-2.16.1 and binutils-2.16.91.0.6,
+   support for 64-bit PC-relative relocations was added, so maybe this
+   hackery can go away sometime.
