[MachineOutliner] Add optimisation remarks for successful outlining

This commit adds optimisation remarks for outlining which fire when a function
is successfully outlined.

To do this, OutlinedFunctions must now contain references to their Candidates.
Since the Candidates must still be sorted and worked on separately, this is
done by working on everything in terms of shared_ptrs to Candidates. This is
good; it means that we can easily move everything to outlining in terms of
the OutlinedFunctions rather than the individual Candidates. This is far more
intuitive than what's currently there!

(Remarks are output when a function is created for some group of Candidates.
In a later commit, all of the outlining logic should be rewritten so that we
loop over OutlinedFunctions rather than over Candidates.)

6 years agoAdd a new Simulator entry for the target triple environment.
Bob Wilson [Mon, 23 Oct 2017 21:51:50 +0000 (21:51 +0000)]
Add a new Simulator entry for the target triple environment.

Apple's iOS, tvOS and watchOS simulator platforms have never been clearly
distinguished in the target triples. Even though they are intended to
behave similarly to the corresponding device platforms, they have separate
SDKs and are really separate platforms from the compiler's perspective.
Clang now defines a macro when building for one of these simulator platforms
(r297866) but that relies on the very indirect mechanism of checking to see
which option was used to specify the minimum deployment target. That is not
so great. Swift would also like to distinguish these simulator platforms in
a similar way, but unlike Clang, Swift does not use a separate option to
specify the minimum deployment target -- it uses a -target option to
specify the target triple directly, including the OS version number.
Using a different target triple for the simulator platforms is a much
more direct and obvious way to specify this. Putting the "simulator" in
the environment component of the triple means the OS values can stay the
same and existing code the looks at the OS field will not be affected.

Make x86 __ehhandler comdat if parent function is

Summary:
This change comes from using lld for i686-windows-msvc. Before this change, lld
emits an error of:

    error: relocation against symbol in discarded section: .xdata

It's possible that this could be addressed in lld, but I think this change is
reasonable on its own.

At a high level, this is being generated:

    A (.text comdat) -> B (.text) -> C (.xdata comdat)

Where A is a C++ inline function, which references B, an exception handler
thunk, which references C, the exception handling info.

With this structure, lld will error when applying relocations to B if the C it
references has been discarded (some other C has been selected).

This change checks if A is comdat, and if so places the exception registration
thunk (B) in the comdata group of A (and B).

It appears that MSVC makes the __ehhandler function comdat.

Is it possible that duplicate thunks are being emitted into the final binary
with other linkers, or are they stripping the unused thunks?
