+//
+// When resolving an address using the ELF ABI TOC pointer, two relocations are
+// generally required: one for the high part and one for the low part. Only
+// the high part generally explicitly depends on r2 (the TOC pointer). And, so,
+// we might produce code like this:
+//
+// .Ltmp526:
+// addis 3, 2, .LC12@toc@ha
+// .Ltmp1628:
+// std 2, 40(1)
+// ld 5, 0(27)
+// ld 2, 8(27)
+// ld 11, 16(27)
+// ld 3, .LC12@toc@l(3)
+// rldicl 4, 4, 0, 32
+// mtctr 5
+// bctrl
+// ld 2, 40(1)
+//
+// And there is nothing wrong with this code, as such, but there is a linker bug
+// in binutils (https://sourceware.org/bugzilla/show_bug.cgi?id=18414) that will
+// misoptimize this code sequence to this:
+// nop
+// std r2,40(r1)
+// ld r5,0(r27)
+// ld r2,8(r27)
+// ld r11,16(r27)
+// ld r3,-32472(r2)
+// clrldi r4,r4,32
+// mtctr r5
+// bctrl
+// ld r2,40(r1)
+// because the linker does not know (and does not check) that the value in r2
+// changed in between the instruction using the .LC12@toc@ha (TOC-relative)
+// relocation and the instruction using the .LC12@toc@l(3) relocation.
+// Because it finds these instructions using the relocations (and not by
+// scanning the instructions), it has been asserted that there is no good way
+// to detect the change of r2 in between. As a result, this bug may never be
+// fixed (i.e. it may become part of the definition of the ABI). GCC was
+// updated to add extra dependencies on r2 to instructions using the @toc@l
+// relocations to avoid this problem, and we'll do the same here.
+//
+// This is done as a separate pass because:
+// 1. These extra r2 dependencies are not really properties of the
+// instructions, but rather due to a linker bug, and maybe one day we'll be
+// able to get rid of them when targeting linkers without this bug (and,
+// thus, keeping the logic centralized here will make that
+// straightforward).
+// 2. There are ISel-level peephole optimizations that propagate the @toc@l
+// relocations to some user instructions, and so the exta dependencies do
+// not apply only to a fixed set of instructions (without undesirable
+// definition replication).
