As Sanjay suggested when he added the hook, PPC should return true from

googletest formatted tests are discovered by running the test executable. 
Previously testing would silently succeed if the test executable crashed 
during the discovery process. Now testing fails with "error: unable to 
discover google-tests ..." if the test executable exits with a non-zero status.

Following a suggestion by Sanjay, we should lower:

  %shl = shl i32 1, %y
  %and = and i32 %x, %shl
  %cmp = icmp eq i32 %and, %shl
  ret i1 %cmp

into:

  subfic r4, r4, 32
  rlwnm r3, r3, r4, 31, 31

Add this pattern and some associated patterns for the 64-bit case and the
not-equal case. Fixes PR27356.

If the entire blocks match, we would count the branch instructions

This wasn't really well explicitly tested with a nice unittest before.
It seems good to have reasonably broken out unittests for this kind of
functionality as I'm workin go other invalidation features to make sure
none of the existing ones regress.

This still has too much duplicated code, I plan to factor that out in
a subsequent commit to use common helpers for repeated parts of this.

If we failed to commit the buffer but did not die to a signal, the temp
file would remain on disk on Windows. Having an open file mapping and
file handle prevents the file from being deleted. I am choosing not to
add an assertion of success on the temp file removal, since virus
scanners and other environmental things can often cause removal to fail
in real world tools.

Also fix more temp file leaks in unit tests.

passes.

This simplifies the test some and makes it more focused and clear what
is being tested. It will also make it much easier to extend with further
testing of different pass behaviors.

I've also replaced a pointless module pass with running the requires
pass directly as that is all that it was really doing.

Summary:
This is pretty useful especially in connection with
BFI's -view-block-freq-propagation-dags.  It helped me to track down the
bug that is being fixed in D24118.

While -view-block-freq-propagation-dags displays the high-level
information with static heuristics included (and block frequencies), the
new thing only shows the raw weight as presented by PGO without any of
the static estimates.  This helps to distinguished what has been
measured vs. estimated.

For the sample loop in D24118, -view-block-freq-propagation-dags=integer
looks like this:

While with -view-cfg-only you can see the underlying branch weights:

When applying our address-formation PPC64 peephole, we are reusing the @ha TOC
addis value with the low parts associated with different offsets (i.e.
different effective symbol addends). We were assuming this was okay so long as
the offsets were less than the alignment of the global variable being accessed.
This ignored the fact, however, that the TOC base pointer itself need only be
8-byte aligned. As a result, what we were doing is legal only for offsets less
than 8 regardless of the alignment of the object being accessed.

Fixes PR28727.

llvm-svn: 280441

The logic in this function assumes that the P8 supports fusion of addis/addi,
but it does not. As a result, there is no advantage to restricting our peephole
application, merging addi instructions into dependent memory accesses, even
when the addi has multiple users, regardless of whether or not we're optimizing
for size.

We might need something like this again for the P9; I suspect we'll revisit
this code when we work on P9 tuning.
