See LICENSE.TXT for details. +// +//===----------------------------------------------------------------------===// +// +// 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). +// +//===----------------------------------------------------------------------===// + +#include "PPCInstrInfo.h" +#include
