by aheejinUse Register over unsigned in LateEHPrepare (NFC)
Summary: While D65962 is pending for review, I landed D65475 that added
one more use of `unsigned`. Changed it to `Register`.

by nicolasweberclang: Don't warn on unused momit-leaf-frame-pointer when frame pointers
are off.
This fixes a regression from r365860: As that commit message states,
there are 3 valid states targeted by the combination of
-f(no-)omit-frame-pointer and -m(no-)omit-leaf-frame-pointer.
After r365860 it's impossible to get from state 10 (omit just leaf frame
pointers) to state 11 (omit all frame pointers) in a single command line
without getting a warning.
This change restores that functionality.
Fixes PR42966.

by Steven Wu[AutoUpgrader] Make ArcRuntime Autoupgrader more conservative
Summary: This is a tweak to r368311 and r368646 which auto upgrades the
calls to objc runtime functions to objc runtime intrinsics, in order to
make sure that the auto upgrader does not trigger with up-to-date
bitcode.
It is possible for bitcode that is up-to-date to contain direct calls to
objc runtime function and those are not inserted by compiler as part of
ARC and they should not be upgraded. Now auto upgrader only triggers as
when the old style of ARC marker is used so it is guaranteed that it
won't trigger on update-to-date bitcode.
This also means it won't do this upgrade for bitcode from llvm-8 and
llvm-9, which preserves the behavior of those releases. Ideally they
should be upgraded as well but it is more important to make sure
AutoUpgrader will not trigger on up-to-date bitcode.

by aktoon[llvm-profdata] Profile dump for compact binary format
Summary: Fix "llvm-profdata show" so it can work with compact binary
format profile. The change is to mark all functions "used" so
SampleProfileReaderCompactBinary::read will read in all profiles
available for dumping. The function names will be MD5 hash for compact
binary format.

by Jan Korous[clang] Refactor doc comments to Decls attribution
- Create ASTContext::attachCommentsToJustParsedDecls so we don't have to
load external comments in Sema when trying to attach existing comments
to just parsed Decls.
- Keep comments ordered and cache their decomposed location - faster
SourceLoc-based searching.
- Optimize work with redeclarations.
- Keep one comment per redeclaration chain (represented by canonical
Decl) instead of comment per redeclaration.
- For redeclaration chains with no comment attached keep just the last
declaration in chain that had no comment instead of every comment-less
redeclaration.

by david.green[ARM] Add MVE beats vector cost model
The MVE architecture has the idea of "beats", where a vector instruction
can be executed over several ticks of the architecture. This adds a
similar system into the Arm backend cost model, multiplying the cost of
all vector instructions by a factor.
This factor essentially becomes the expected difference between scalar
code and vector code, on average. MVE Vector instructions can also
overlap so the a true cost of them is often lower. But equally scalar
instructions can in some situations be dual issued, or have other
optimisations such as unrolling or make use of dsp instructions. The
default is chosen as 2. This should not prevent vectorisation is a most
cases (as the vector instructions will still be doing at least 4 times
the work), but it will help prevent over vectorising in cases where the
benefits are less likely.
This adds things so far to the obvious places in ARMTargetTransformInfo,
and updates a few related costs like not treating float instructions as
cost 2 just because they are floats.
