Always pass a diagnostic handler to the linker.

Before this patch the diagnostic handler was optional. If it was not
passed, the one in the LLVMContext was used.

That is probably not a pattern we want to follow. If each area has an
optional callback, there is a sea of callbacks and it is hard to follow
which one is called.

Doing this also found cases where the callback is a nice addition, like
testing that no errors or warnings are reported.

The other option is to always use the diagnostic handler in the
LLVMContext. That has a few problems

* To implement the C API we would have to set the diag handler and then
  set it back to the original value.
* Code that creates the context might be far away from code that wants
  the diagnostics.

an RFC.

We can exploit the likely commonality by uniqueing the usage information after querying the pass, but before storing it into the pass manager. This greatly reduces memory consumption by the AnalysisUsage objects. For a long pass pipeline, I measured a decrease in memory consumption for this storage of about 50%. I have not measured on the default O3 pipeline, but I suspect it will see some benefit as well since many passes are repeated (e.g. InstCombine).

Don't punish vectorized arithmetic instruction whose type will be split to multiple registers

Currently in LLVM's cost model, a vectorized arithmetic instruction will have
high cost if its type is split into multiple registers. However, this
punishment is too heavy and unnecessary. The overhead of the split should not
be on arithmetic instructions but instructions that implement the split. Note
that during vectorization we have calculated the register pressure, and we
only choose proper interleaving factor (and also vectorization factor) so
that we don't use more registers than the maximum number.

Here is a very simple example: if a vadd has the cost 1, and if we double VF
so that we need two registers to perform it, then its cost will become 4 with
the current implementation, which will prevent us to use larger VF.

JF Bastien [Thu, 3 Dec 2015 23:43:56 +0000 (23:43 +0000)]
CodeGen peephole: fold redundant phys reg copies

Code generation often exposes redundant physical register copies through
virtual registers such as:

  %vreg = COPY %PHYSREG
  %PHYSREG = COPY %vreg

There are cases where no intervening clobber of %PHYSREG occurs, and the
later copy could therefore be removed. In some cases this further allows
us to remove the initial copy.

This patch contains a motivating example which comes from the x86 build
of Chrome, specifically cc::ResourceProvider::UnlockForRead uses
libstdc++'s implementation of hash_map. That example has two tests live
at the same time, and after machine sinking LLVM has confused itself
enough and things spilling EFLAGS is a great idea even though it's
never restored and the comparison results are both live.

Before this patch we have:
  DEC32m %RIP, 1, %noreg, <ga:@L>, %noreg, %EFLAGS<imp-def>
  %vreg1<def> = COPY %EFLAGS; GR64:%vreg1
  %EFLAGS<def> = COPY %vreg1; GR64:%vreg1
  JNE_1 <BB#1>, %EFLAGS<imp-use>

Both copies are useless. This patch tries to eliminate the later copy in
a generic manner.

dec is especially confusing to LLVM when compared with sub.

I wrote this patch to treat all physical registers generically, but only
remove redundant copies of non-allocatable physical registers because
the allocatable ones caused issues (e.g. when calling conventions weren't
properly modeled) and should be handled later by the register allocator

The following tests used to failed when the patch also replaced allocatable
This happens because COPY has other special meaning for e.g. dependency
breakage and x87 FP stack.

Note that all other backends' tests pass.

DenseMap is most applicable when both keys and values are small.

significant memory overhead. A std::unordered_map is more appropriate
