Rafael Espindola 8b6604b87a Bring back r293480. It is safe now.
Original message:

    Fix the values of two xcore ELF flags.

    The values in llvm grew from a pre-MC day when they would not show up
    in .o files and are outside of the SHF_MASKPROC.

    Fortunately the MC output is not currently used as xcore has its own
    assemble and that assembler uses valid values. This updates llvm to
    use the same values as the xmos assembler.

Rafael Espindola e0eba3c493 Only print architecture dependent flags for that architecture.
Different architectures can have different meaning for flags in the
SHF_MASKPROC mask, so we should always check what the architecture use
before checking the flag.

NFC for now, but will allow fixing the value of an xmos flag.

Jonas Paulsson 3f71d6a38e [LoopVectorize] Improve getVectorCallCost() getScalarizationOverhead() call.
By calling getScalarizationOverhead with the CallInst instead of the types of
its arguments, we make sure that only unique call arguments are added to the
scalarization cost.

getScalarizationOverhead() is extended to handle calls by only passing on the
actual call arguments (which is not all the operands).

This also eliminates a wrapper function with the same name.

Matthias Braun a4976c6166 MachineInstr: Remove parameter from dump()
The primary use of the dump() functions in LLVM is for use in a
debugger. Unfortunately lldb does not seem to handle default arguments
so using `p SomeMI.dump()` fails and you have to type the longer `p
SomeMI.dump(nullptr)`. Remove the paramter to make the most common use
easy. (You can always construct something like `p
SomeMI.print(dbgs(),MyTII)` if you need more features).

Simon Pilgrim 76073f8d22 [X86][SSE] Lower scalar_to_vector(0) to zero vector
Replaces an xor+movd/movq with an xorps which will be shorter in codesize, avoid an int-fpu transfer, allow modern cores to fast path the result during decode and helps other combines recognise an all-zero vector.

The only reason I can think of that we'd want to keep scalar_to_vector in this case is to help recognise the upper elts are undef but this doesn't seem to be a problem.

Chandler Carruth cd836cd4ee [ArgPromote] Re-arrange the code in a more typical, logical way.
This arranges the static helpers in an order where they are defined
prior to their use to avoid the need of forward declarations, and
collect the core pass components at the bottom below their helpers.

This also folds one trivial function into the pass itself. Factoring
this 'runImpl' was an attempt to help porting to the new pass manager,
however in my attempt to begin this port in earnest it turned out to not
be a substantial help. I think it will be easier to factor things
without it.

This is an NFC change and does a minimal amount of edits over all.
Subsequent NFC cleanups will normalize the formatting with clang-format
and improve the basic doxygen commenting.
