Lawrence D'Anna adbf64ccc9 [LLDB][Python] remove ArgInfo::count
Summary:
This patch updates the last user of ArgInfo::count and deletes
it.   I also delete `GetNumInitArguments()` and `GetInitArgInfo()`.
Classess are callables and `GetArgInfo()` should work on them.

On python 3 it already works, of course. `inspect` is good.

On python 2 we have to add yet another special case.   But hey if
python 2 wasn't crufty we wouln't need python 3.

I also delete `is_bound_method` becuase it is unused.

This path is tested in `TestStepScripted.py`

Stanislav Mekhanoshin 4312c4afd4 [AMDGPU] deduplicate tablegen predicates
We are duplicating predicates if several parts of the combined
predicate list contain the same condition. Added code to deduplicate
the list.

We have AssemblerPredicates and AssemblerPredicate in the
PredicateControl, but we never use AssemblerPredicates with an
actual list, so this one is dropped.

This addresses the first part of the llvm bug 43886:

Craig Topper b2b6a54f84 [X86] Add support for -mvzeroupper and -mno-vzeroupper to match gcc
-mvzeroupper will force the vzeroupper insertion pass to run on
CPUs that normally wouldn't. -mno-vzeroupper disables it on CPUs
where it normally runs.

To support this with the default feature handling in clang, we
need a vzeroupper feature flag in X86.td. Since this flag has
the opposite polarity of the fast-partial-ymm-or-zmm-write we
used to use to disable the pass, we now need to add this new
flag to every CPU except KNL/KNM and BTVER2 to keep identical
behavior.

Remove -fast-partial-ymm-or-zmm-write which is no longer used.

Philip Reames 6ff439b57f [SimplifyCFG] Use a (trivially) dominanting widenable branch to remove later slow path blocks
This transformation is a variation on the GuardWidening transformation we have checked in as it's own pass. Instead of focusing on merge (i.e. hoisting and simplifying) two widenable branches, this transform makes the observation that simply removing a second slowpath block (by reusing an existing one) is often a very useful canonicalization. This may lead to later merging, or may not. This is a useful generalization when the intermediate block has loads whose dereferenceability is hard to establish.

As noted in the patch, this can be generalized further, and will be.

Michał Górny 6eca4f4691 [lldb] [Process/NetBSD] Add register info for missing register sets
Add info for all register sets supported in NetBSD, particularly for all
registers 'expected' by LLDB.  This is necessary in order to fix
python_api/lldbutil/iter/TestRegistersIterator.py test that currently
fails due to missing names of register sets (None).

This copies fpreg descriptions from Linux, and combines Linux' AVX
and MPX registers into a single XState group, to fit NetBSD register
group design.  Technically, we do not support MPX registers
at the moment but gdb-remote insists on passing their errors anyway,
and if we do not include it in any group, they end up in a separate
anonymous group that breaks the test.

While at it, swap the enums for XState and DBRegs to match register set
ordering.

This also adds a few consts to the lldb-x86-register-enums.h to provide
more consistency between user registers and debug registers.

Eric Astor be6ac471f6 [ms] Fix Microsoft compatibility handling of commas in nested macro expansions.
In Microsoft-compatibility mode, single commas from nested macro expansions
should not be considered as argument separators; we already emulated this by
marking them to be ignored. However, in MSVC's preprocessor, subsequent
expansions DO treat these commas as argument separators... so we now ignore
each comma at most once.

Includes a small unit test that validates we match MSVC's behavior as shown
in https://gcc.godbolt.org/z/y0twaq

Jinsong Ji 40d0d4e233 Lower generic MASSV entries to PowerPC subtarget-specific entries
This patch (second of two patches) lowers the generic PowerPC vector
entries to PowerPC subtarget-specific entries.
For instance, the PowerPC generic entry 'cbrtd2_massv' is lowered to
'cbrtd2_P9' or Power9 subtarget.

The first patch enables the vectorizer to recognize the IBM MASS vector
library routines. This patch specifically adds support for recognizing
the '-vector-library=MASSV' option, and defines mappings from IEEE
standard scalar math functions to generic PowerPC MASS vector
counterparts.
For instance, the generic PowerPC MASS vector entry for double-precision
'cbrt' function is '__cbrtd2_massv'

The overall support for MASS vector library is presented as such in two
patches for ease of review.

This reverts commit 004ed2b0d1.
Original commit hash 6d03890384

Summary:
This adds a clang option to disable inline line tables. When it is used,
the inliner uses the call site as the location of the inlined function instead of
marking it as an inline location with the function location.

Peter Collingbourne 2c6fae179e ELF: Discard .ARM.exidx sections for empty functions instead of misordering them.
The logic added in r372781 caused ARMExidxSyntheticSection::addSection()
to return false for exidx sections without a link order dep that passed
isValidExidxSectionDep(). This included exidx sections for empty functions. As
a result, such exidx sections would end up treated like ordinary sections and
would end up being laid out before the ARMExidxSyntheticSection, most likely in
the wrong order relative to the exidx entries in the ARMExidxSyntheticSection,
breaking the orderedness invariant relied upon by unwinders. Fix this by
simply discarding such sections.

Thomas Preud'homme 0bab0538d8 [test] Use system locale for mri-utf8.test
Summary:
llvm-ar's mri-utf8.test test relies on the en_US.UTF-8 locale to be
installed for its last RUN line to work. If not installed, the unicode
string gets encoded (interpreted) as ascii which fails since the most
significant byte is non zero. This commit changes the test to only rely
on the system being able to encode the pound sign in its default
encoding (e.g. UTF-16 for Microsoft Windows) by always opening the file
via input/output redirection. This avoids forcing a given locale to be
present and supported. A Byte Order Mark is also added to help
recognizing the encoding of the file and its endianness. Finally the
XFAIL on system-darwin is removed since the test actually passes fine on
Mac OS X and XFAIL was only added because it failed before.

Jonas Paulsson b7b170c9b4 [MachineVerifier] Improve verification of live-in lists.
MachineVerifier::visitMachineFunctionAfter() is extended to check the
live-through case for live-in lists. This is only done for registers without
aliases and that are neither allocatable or reserved, such as the SystemZ::CC
register.

The MachineVerifier earlier only catched the case of a live-in use without
an entry in the live-in list (as "using an undefined physical register").

A comment in LivePhysRegs.h has been added stating a guarantee that
addLiveOuts() can be trusted for a full register both before and after
register allocation.

David Green 91b0cad813 [ARM] Use isFMAFasterThanFMulAndFAdd for MVE
The Arm backend will usually return false for isFMAFasterThanFMulAndFAdd,
where both the fused VFMA.f32 and a non-fused VMLA.f32 are usually
available for scalar code. For MVE we don't have the non-fused version
though. It makes more sense for isFMAFasterThanFMulAndFAdd to return
true, allowing us to simplify some of the existing ISel patterns.

The tests here are that non of the existing tests failed, and so we are
still selecting VFMA and VFMS. The one test that changed shows we can
now select from fast math flags, as opposed to just relying on the
isFMADLegalForFAddFSub option.
