Craig Topper fd2c6a3be0 [TableGen] Modify the AsmMatcherEmitter to only apply the table growth from r252440 to the Hexagon target.
This restores the previous behavior of not including the mnemonic in the classes table for every target that starts instruction lines with the mnemonic. Not only did the table size increase by 1 entry, but the class enum increased in size which caused every class in the array to increase in size. It also grew the size of the function that parsers tokens into classes by a substantial amount.

This adds a new HasMnemonicFirst flag to all AsmParsers. It's set to 1 by default and Hexagon target overrides it to 0.

For the X86 target alone this recovers 324KB of size on the llvm-mc executable.

I believe the current state is still a bad design choice for the Hexagon target as it causes most of the parsing to do a linear search through the entire match table to comparing operands against every instruction until it finds one that works. At least for the other targets we do a binary search based on mnemonic over which to do the linear scan.

Dan Liew 7574241053 [lit] Implement support of per test timeout in lit.
This should work with ShTest (executed externally or internally) and GTest
test formats.

To set the timeout a new option ``--timeout=`` has
been added which specifies the maximum run time of an individual test
in seconds. By default this 0 which causes no timeout to be enforced.

The timeout can also be set from a lit configuration file by modifying
the ``lit_config.maxIndividualTestTime`` property.

To implement a timeout we now require the psutil Python module if a
 timeout is requested. This dependency is confined to the newly added
 ``lit.util.killProcessAndChildren()``. A note has been added into the
 TODO document describing how we can remove the dependency on the
 ``pustil`` module in the future. It would be nice to remove this
 immediately but that is a lot more work and Daniel Dunbar believes it is
better that we get a working implementation first and then improve it.

To avoid breaking the existing behaviour the psutil module will not be
imported if no timeout is requested.

The included testcases are derived from test cases provided by
 Jonathan Roelofs which were in an previous attempt to add a per test
 timeout to lit (http://reviews.llvm.org/D6584). Thanks Jonathan!

Akira Hatanaka 1cb242eb13 Provide a way to specify inliner's attribute compatibility and merging.
This reapplies r256277 with two changes:

- In emitFnAttrCompatCheck, change FuncName's type to std::string to fix

- Remove an unnecessary install-local target in lib/IR/Makefile.

Hal Finkel cd5f984670 [TableGen] Correct Namespace lookup with AltNames in AsmWriterEmitter
AsmWriterEmitter will generate a getRegisterName function with an alternate
register name index as its second argument if the target makes use of them. The
enum of these values is generated in RegisterInfoEmitter. The getRegisterName
generator would assume the namespace could always be found by reading index 1
of the list of AltNameIndices, but this will fail if this list is sorted such
that the NoRegAltName is at index 1. Because this list is sorted by record name
(in CodeGenTarget::ReadRegAltNameIndices), you only run in to problems if your
MyTargetRegisterInfo.td defines a single RegAltNameIndex that sorts lexically
before NoRegAltName.

For example, if a target has something like

  def AnAltNameIndex : RegAltNameIndex

and defines RegAltNameIndices for some registers then, prior to this change,
AsmWriterEmitter would generate references to

  ::AnAltNameIndex and ::NoRegAltName

Dan Liew 26da45c2bb [lit] Fix bug when using Python3 where a failing test would not show
the script when running a ShTest with an external or internal shell.

This bug is caused by use of the ``map`` function in Python 3 which
returns an iterable (rather than a list in Python 2). After the iterable
is exhausted it won't return any more output and consequently when
``_runShTest()`` tries to access the ``script`` which has already been
iterated over it is empty. Converting to a list immediatley after
calling ``map()`` fixes this.

This fixes the ``tests/shtest-format.py`` test when running under
Python3 which was previously failing.

Rafael Espindola 55512f9b25 Default SetVector to use a DenseSet.
We use to have an odd difference among MapVector and SetVector. The map
used a DenseMop, but the set used a SmallSet, which in turn uses a
std::set.

I have changed SetVector to use a DenseSet. If you were depending on the
old behaviour you can pass an explicit set type or use SmallSetVector.
The common cases for needing to do it are:

* Optimizing for small sets.
* Sets for types not supported by DenseSet.

Matthias Braun fe9d6f211f Assume lane masks are always precise
Allowing imprecise lane masks in case of more than 32 sub register lanes
lead to some tricky corner cases, and I need another bugfix for another
one. Instead I rather declare lane masks as precise and let tablegen
abort if we do not have enough bits.

This does not affect any in-tree target, even AMDGPU only needs 16 lanes
at the moment. If the 32 lanes turn out to be a problem in the future,
then we can easily change the LaneBitmask typedef to uint64_t.

Dan Liew 82bd29b13c [lit] Fix bug where ``lit.util.which()`` would return a directory
instead of executable if the argument was found inside a directory
contained in PATH.

An example where this could cause a problem is if there was a RUN line
that ran the ``test`` command and if the user had a directory in their
PATH that contained a directory called ``test/`` (that occured before
``/usr/bin/``). Lit would try to use the directory as the executable
which would fail with the rather cryptic message.

Hal Finkel 942e949f0d [lit] Raise the default soft process limit when possible
It is common to have a default soft process limit, at least on some families of
Linux distributions, of 1024. This is normally more than enough, but if you
have many cores, and you're running tests that create many threads, this can
become a problem. My POWER7 development machine has 48 cores, and when running
the lld regression tests, which often want to create up to 48 threads, I run
into problems. lit, by default, will want to run 48 tests in parallel, and
48*48 < 1024, and so many tests fail like this:

terminate called after throwing an instance of 'std::system_error'

what():  Resource temporarily unavailable
or lit fails like this when launching a test:

OSError: [Errno 11] Resource temporarily unavailable

lit can easily detect this situation and attempt to repair it before launching
tests (by raising the soft process limit to something that will allow ncpus^2
threads to be created), and should do so to prevent spurious test failures.

This is the follow-up to this thread:

Maksim Panchenko cce239c45d HHVM calling conventions.
HHVM calling convention, hhvmcc, is used by HHVM JIT for
functions in translated cache. We currently support LLVM back end to
generate code for X86-64 and may support other architectures in the
future.

In HHVM calling convention any GP register could be used to pass and
return values, with the exception of R12 which is reserved for
thread-local area and is callee-saved. Other than R12, we always
pass RBX and RBP as args, which are our virtual machine's stack pointer
and frame pointer respectively.

When we enter translation cache via hhvmcc function, we expect
the stack to be aligned at 16 bytes, i.e. skewed by 8 bytes as opposed
to standard ABI alignment. This affects stack object alignment and stack
adjustments for function calls.

One extra calling convention, hhvm_ccc, is used to call C++ helpers from
HHVM's translation cache. It is almost identical to standard C calling
convention with an exception of first argument which is passed in RBP
(before we use RDI, RSI, etc.)

Previously the code added an extra nullptr entry to a static array and then created an ArrayRef with a size one less than the static array. If there were no other entries the array would just contain the nullptr and the ArrayRef would be crated with size 0.

Instead, put the right number of entries in the array and explicitly emit 'None' if the size would be 0. This allows the static array constructor of makeArrayRef to be used.

Daniel Sanders 153010c52d Re-commit r247683: Replace Triple with a new TargetTuple in MCTargetDesc/* and related. NFC.
Summary:
This is the first patch in the series to migrate Triple's (which are ambiguous)
to TargetTuple's (which aren't).

For the moment, TargetTuple simply passes all requests to the Triple object it
holds. Once it has replaced Triple, it will start to implement the interface in
a more suitable way.

This change makes some changes to the public C++ API. In particular,
InitMCSubtargetInfo(), createMCRelocationInfo(), and createMCSymbolizer()
now take TargetTuples instead of Triples. The other public C++ API's have
been left as-is for the moment to reduce patch size.

This commit also contains a trivial patch to clang to account for the C++ API
change. Thanks go to Pavel Labath for fixing LLDB for me.

Rafael Espindola 7915b9eb42 Cleaning up LLVM IR mode for Emacs.
I've made a range of improvements to the Emacs mode for LLVM IR.

Most importantly, it changes llvm-mode to inherit from prog-mode. This
means llvm-mode will be treated as a normal programming mode in Emacs,
so many Emacs features will just work. prog-mode is new to Emacs 24,
so I've added an alias to ensure compatibility with Emacs 23 too.

I've changed the mode definition to use define-derived-mode. This
saves us needing to set up local variables ourselves, and saves us
needing to define llvm-mode-map, llvm-mode-abbrev-table,
llvm-mode-map.

I've removed the keybindings to tab-to-tab-stop, center-line and
center-paragraph. This shouldn't be llvm-mode's responsibility, and
the code didn't actually work anyway (since `(not llvm-mode-map)`
always evaluated to `t`, the keybindings were never executed).

I've simplified the syntax-table definition, it's equivalent (e.g. `"`
is treated as string delimiter by default in Emacs). I've added `.` as
a symbol constituent, so functions like `llvm.memset.p0i8.i32` are
recognised as a single symbol. I've also changed `%` to be a symbol
constituent, so users can move between words or symbols at their
choice, rather than conflating the two.

I've fixed regexp for types, which incorrect used `symbol` instead of
`symbols` as an argument to `regexp-opt`. This was causing incorrect
highlighting on lines like `call void @foovoid`.

I've removed string and comment highlighting from
`llvm-font-lock-keywords`. This is already handled by the
syntax-table.

Finally, I've removed the reference to jasmin. That project is long
abandoned and the link 404s. For reference, I've found an old copy of
the project here:
https://github.com/stevej/emacs/blob/master/vendor/jasmin/jasmin.el

Dan Liew 1e3dc527ea Filter libraries that are not installed out of CMake exports (currently
gtest and gtest_main) when generating ``Makefile.llvmbuild``.

Libraries that are not installed should not be exported because they
won't be available from an install tree.  Rather than filtering out the
gtest libraries in cmake/modules/Makefile, simply teach llvm-build to
filter out libraries that will not be installed from its generated list
of exported libraries.

Note that LLVMBUILD_LIB_DEPS_* are used during our own CMake build
process so we cannot filter LLVMBUILD_LIB_DEPS_gtest* out in llvm-build.
We must leave this gtest filter logic in cmake/modules/Makefile.

Move `LLVM_LIBS_TO_EXPORT` over to Makefile.llvmbuild and generate it

This refactoring was originally motivated by issue #24154 due to commit
r243297 (Fix `llvm-config` to emit the linker flag for the combined
shared object, 2015-07-27) changing the output of `llvm-config --libs`

Chandler Carruth 194f59ca5d [PM/AA] Extract the ModRef enums from the AliasAnalysis class in
preparation for de-coupling the AA implementations.

In order to do this, they had to become fake-scoped using the
traditional LLVM pattern of a leading initialism. These can't be actual
scoped enumerations because they're bitfields and thus inherently we use
them as integers.

I've also renamed the behavior enums that are specific to reasoning
about the mod/ref behavior of functions when called. This makes it more
clear that they have a very narrow domain of applicability.

I think there is a significantly cleaner API for all of this, but
I don't want to try to do really substantive changes for now, I just
want to refactor the things away from analysis groups so I'm preserving
the exact original design and just cleaning up the names, style, and
lifting out of the class.

JF Bastien e4d22d59d1 Targets: commonize some stack realignment code
This patch does the following:
* Fix FIXME on `needsStackRealignment`: it is now shared between multiple targets, implemented in `TargetRegisterInfo`, and isn't `virtual` anymore. This will break out-of-tree targets, silently if they used `virtual` and with a build error if they used `override`.
* Factor out `canRealignStack` as a `virtual` function on `TargetRegisterInfo`, by default only looks for the `no-realign-stack` function attribute.

Multiple targets duplicated the same `needsStackRealignment` code:
 - Aarch64.
 - ARM.
 - Mips almost: had extra `DEBUG` diagnostic, which the default implementation now has.
 - PowerPC.
 - WebAssembly.
 - x86 almost: has an extra `-force-align-stack` option, which the default implementation now has.

The default implementation of `needsStackRealignment` used to just return `false`. My current patch changes the behavior by simply using the above shared behavior. This affects:
 - AMDGPU
 - BPF
 - CppBackend
 - MSP430
 - NVPTX
 - Sparc
 - SystemZ
 - XCore
 - Out-of-tree targets
This is a breaking change! `make check` passes.

The only implementation of the `virtual` function (besides the slight different in x86) was Hexagon (which did `MF.getFrameInfo()->getMaxAlignment() > 8`), and potentially some out-of-tree targets. Hexagon now uses the default implementation.

`needsStackRealignment` was being overwritten in `<Target>GenRegisterInfo.inc`, to return `false` as the default also did. That was odd and is now gone.

Hans Wennborg 0caeee07e1 Switch the release script to build with CMake by default (PR21561)
It retains the possibility to use the autoconf build with a
command-line option ('-use-autoconf'), and uses that by default on Darwin since
compiler-rt requires it on that platform.

This commit also removes the "Release-64" flavour and related logic. The script
would previously do two builds unless the '-no-64bit' flag was passed, but on
my machine and from those I asked this always ended up producing two 64-bit builds,
causing much confusion.

It also removes the -build-triple option, which caused the --build= flag to
get passed to ./configure. This was presumably intended for cross-compiling,
but none of the release testers use it. If someone does want to pass it,
they can use '-configure-flags --build=foo' instead.

Petr Pavlu 182b05784a [TableGen] Improve decoding options for non-orthogonal instructions
When FixedLenDecoder matches an input bitpattern of form [01]+ with an
instruction bitpattern of form [01?]+ (where 0/1 are static bits and ? are
mixed/variable bits) it passes the input bitpattern to a specific instruction
decoder method which then makes a final decision whether the bitpattern is a
valid instruction or not. This means the decoder must handle all possible
values of the variable bits which sometimes leads to opcode rewrites in the
decoder method when the instructions are not fully orthogonal.

The patch provides a way for the decoder method to say that when it returns
Fail it does not necessarily mean the bitpattern is invalid, but rather that
the bitpattern is definitely not an instruction that is recognized by the
decoder method. The decoder can then try to match the input bitpattern with
other possible instruction bitpatterns.

For example, this allows to solve a situation on AArch64 where the `MSR
(immediate)` instruction has form:
1101 0101 0000 0??? 0100 ???? ???1 1111
but not all values of the ? bits are allowed. The rejected values should be
handled by the `extended MSR (register)` instruction:
1101 0101 000? ???? ???? ???? ???? ????

The decoder will first try to decode an input bitpattern that matches both
bitpatterns as `MSR (immediate)` but currently this puts the decoder method of
`MSR (immediate)` into a situation when it must be able to decode all possible
values of the ? bits, i.e. it would need to rewrite the instruction to `MSR
(register)` when it is not `MSR (immediate)`.

The patch allows to specify that the decoder method cannot determine if the
instruction is valid for all variable values. The decoder method can simply
return Fail when it knows it is definitely not `MSR (immediate)`. The decoder
will then backtrack the decoding and find that it can match the input
bitpattern with the more generic `MSR (register)` bitpattern too.

Dan Liew 7fa38a5349 Fix several issues with the test-release.sh script
* Use the default install prefix (/usr/local) and use DESTDIR instead to
  set a temporary install location for tarballing. This is the correct
  way to package binary releases (otherwise the temporary install path
  ends up in files in the binary release).
* Remove ``-disable-clang`` option. It did not work correctly
  (tarballing assumed phase 3 was run) and when doing a release
  we should always be doing a three-phased build and test.

Note: Technically we should only be using DESTDIR for the third phase
and use --prefix for the first and second phase because we run the built
clang from phase 1 and 2 (and in general an application's behaviour
may depend on the install prefix). However in the case of clang it
seems to not care what the install prefix was so to simplify the script
we use DESTDIR for all three stages.

This change adds an auto-generated static function <Target>GenRegisterInfo::getFrameLowering(const MachineFunction &MF) which does this devirtualization, and uses this function in all targets which can.

Reid Kleckner 60381791b5 Rename llvm.frameescape and llvm.framerecover to localescape and localrecover
Summary:
Initially, these intrinsics seemed like part of a family of "frame"
related intrinsics, but now I think that's more confusing than helpful.
Initially, the LangRef specified that this would create a new kind of
allocation that would be allocated at a fixed offset from the frame
pointer (EBP/RBP). We ended up dropping that design, and leaving the
stack frame layout alone.

These intrinsics are really about sharing local stack allocations, not
frame pointers. I intend to go further and add an `llvm.localaddress()`
intrinsic that returns whatever register (EBP, ESI, ESP, RBX) is being
used to address locals, which should not be confused with the frame
pointer.

Naming suggestions at this point are welcome, I'm happy to re-run sed.

Eric Fiselier 8fcf50515b [LIT] Fix failing LIT tests
Summary:
I spend some time trying to get the LIT test suite passing. Here are the changes that I needed to make on my machine.

I made the following changes for the following reasons.

1. google-test.py: The Google test format now checks for "[  PASSED  ] 1 test." to check if a test passes.
2. discovery.py: The output appears in a different order on my machine than it did in the test.
3. unittest-adaptor.py: The output appears in a different order on my machine than it did in the test.
4. The classname is now formed differently in `getJUnitXML(...)`.

I'm not sure what is causing the output order to differ in discovery.py and unittest-adaptor.py. Does anybody have any thoughts?

Arnold Schwaighofer f4d5a8ec9e lit: Allow configurations to restrict the set of tests to run
By setting limit_to_features to a non empty list of features a configuration can
restrict the set of tests to run to only include tests that require a feature in
this list.

Hans Wennborg 9c806c432e Drop remaining Dragonegg support in release scripts
r236077 and r236081 dropped Dragonegg support from the release scripts
but left some pieces. The most notable change is that Dragonegg won't
be tagged any more.

Benjamin Kramer f5e2fc474d Replace push_back(Constructor(foo)) with emplace_back(foo) for non-trivial types
If the type isn't trivially moveable emplace can skip a potentially
expensive move. It also saves a couple of characters.


Call sites were found with the ASTMatcher + some semi-automated cleanup.

memberCallExpr(
    argumentCountIs(1), callee(methodDecl(hasName("push_back"))),
    on(hasType(recordDecl(has(namedDecl(hasName("emplace_back")))))),
    hasArgument(0, bindTemporaryExpr(
                       hasType(recordDecl(hasNonTrivialDestructor())),
                       has(constructExpr()))),
    unless(isInTemplateInstantiation()))

No functional change intended.

Ahmed Bougacha eb4dbd8552 [TableGen][AsmMatcherEmitter] Only parse isolated tokens as registers.
Fixes PR23455, where, when TableGen generates the matcher from the
AsmString, it splits "cmp${cc}ss" into tokens, and the "ss" suffix
is recognized as the SS register.

I can't think of a situation where that's a feature, not a bug, hence:
when a token is "isolated", i.e., it is followed and preceded by
separators, it shouldn't be parsed as a register.

Owen Anderson ca5480062a Expand the Flags field of MCInstrDesc to 64 bits, while simultaneously
shrinking the Size and NumDefs fields to offset the size growth, and
reordering the fields to preserve a good packing.

This is necessary in the short term for adding a convergent flag, and
simultaneously future-proofs us against more flags being added in the
future.
