29190e6398 The code section for an ISR has a specific address. 
Currently, whether a function is ISR or not is encoded in the section attribute for that function.

622053fec3 Handle DBG_VALUE mixed with labels when doing PHI 
elimination.  Before a DBG_VALUE could affect codegen.
The solution here is imperfect and not final.

8962ca0e05 Drop support for the InReg attribute on the ppc backend. This was used by 
llvm-gcc but has been replaced with pad argument which don't need any
special backend support.

d19ecedc40 Split the main for-each-use loop again, this time for GenerateTruncates, 
as it also peeks at which registers are being used by other uses. This
makes LSR less sensitive to use-list order.

b410c3010b Reapply 96294; now that I've gotten around to looking 
at older buildbot messages, I see the failure predates
this patch.

df6f49fc2d Something broke. Hard to believe it was this patch 
but it's harder to believe it's the other candidate,
so reverting.  Temporarily I hope.

c85ee6018a Put repeated empty pattern into the AQI instruction class. 
We could almost use a multiclass for the signed/unsigned instructions, but
there are only 6 of them so I guess it's not worth it.

559e34c5fc It turns out that we emitted completely wrong common EH frame since the early beginning! The "z" CIE augmentation mark indicates that there is an extra word containing the size of augmentation section. However, even for frames w/o any augmentation data we emitted size uleb! (this is the case of "unwinding through C code"). Thus frame moves information was emitterd completely wrong.

dccd240998 Preliminary patch to improve dwarf EH generation - Hooks to return Personality / FDE / LSDA / TType encoding depending on target / options (e.g. code model / relocation model) - MCIzation of Dwarf EH printer to use encoding information - Stub generation for ELF target (needed for indirect references) - Some other small changes here and there

A virtual register can be used before it is defined in the same MBB if the MBB
is part of a loop. Teach the implicit-def pass about this case.

it doesn't come back.

b5fe25544c Split SelectionDAGISel::IsLegalAndProfitableToFold to 
IsLegalToFold and IsProfitableToFold. The generic version of the later simply checks whether the folding candidate has a single use.

This allows the target isel routines more flexibility in deciding whether folding makes sense. The specific case we are interested in is folding constant pool loads with multiple uses.
