Relationship maps are represented as InstrMapping records which are parsed by
TableGen and the information is used to construct mapping tables to represent
appropriate relations between instructions. These tables are emitted into
XXXGenInstrInfo.inc file along with the functions to query them.

and also fixes the R_PPC64_TOC16 and R_PPC64_TOC16_DS relocation offset.
The 'nop' is needed so a restore TOC instruction (ld r2,40(r1)) can be placed
by the linker to correct restore the TOC of previous function.

Current code has two issues: it defines in PPCInstr64Bit.td file a LDinto_toc
and LDtoc_restore as a DSForm_1 with DS_RA=0 where it should be
DS=2 (the 8 bytes displacement of the TOC saving). It also wrongly emits a
MC intruction using an uint32_t value while the PPC::BL8_NOP_ELF
and PPC::BLA8_NOP_ELF are both uint64_t (because of the following 'nop').

This patch corrects the remaining ExecutionEngine using MCJIT:

structs having size 3, 5, 6, or 7.  Such a struct must be passed and received
as right-justified within its register or memory slot.  The problem is only
present for structs that are passed in registers.

Previously, as part of a patch handling all structs of size less than 8, I
added logic to rotate the incoming register so that the struct was left-
justified prior to storing the whole register.  This was incorrect because
the address of the parameter had already been adjusted earlier to point to
the right-adjusted value in the storage slot.  Essentially I had accidentally
accounted for the right-adjustment twice.

In this patch, I removed the incorrect logic and reorganized the code to make
the flow clearer.

The removal of the rotates changes the expected code generation, so test case
structsinregs.ll has been modified to reflect this.  I also added a new test
case, jaggedstructs.ll, to demonstrate that structs of these sizes can now
be properly received and passed.

I've built and tested the code on powerpc64-unknown-linux-gnu with no new
regressions.  I also ran the GCC compatibility test suite and verified that
earlier problems with these structs are now resolved, with no new regressions.

This patch adds initial PPC64 TOC MC object creation using the small mcmodel
(a single 64K TOC) adding the some TOC relocations (R_PPC64_TOC,
R_PPC64_TOC16, and R_PPC64_TOC16DS).

The addition of 'undefinedExplicitRelSym' hook on 'MCELFObjectTargetWriter'
is meant to avoid the creation of an unreferenced ".TOC." symbol (used in
the .odp creation) as well to set the R_PPC64_TOC relocation target as the
temporary ".TOC." symbol. On PPC64 ABI, the R_PPC64_TOC relocation should
not point to any symbol.

smaller integer loads and stores.

The high-level motivation is that the frontend sometimes generates
a single whole-alloca integer load or store during ABI lowering of
splittable allocas. We need to be able to break this apart in order to
see the underlying elements and properly promote them to SSA values. The
hope is that this fixes some performance regressions on x86-32 with the
new SROA pass.

Unfortunately, this causes quite a bit of churn in the test cases, and
bloats some IR that comes out. When we see an alloca that consists soley
of bits and bytes being extracted and re-inserted, we now do some
splitting first, before building widened integer "bucket of bits"
representations. These are always well folded by instcombine however, so
this shouldn't actually result in missed opportunities.

If this splitting of all-integer allocas does cause problems (perhaps
due to smaller SSA values going into the RA), we could potentially go to
some extreme measures to only do this integer splitting trick when there
are non-integer component accesses of an alloca, but discovering this is
quite expensive: it adds yet another complete walk of the recursive use
tree of the alloca.

Either way, I will be watching build bots and LNT bots to see what
fallout there is here. If anyone gets x86-32 numbers before & after this
change, I would be very interested.
