367b67df3e [X86] Don't print 'dword ptr' or 'qword ptr' on the operand to some of the LEA variants in Intel syntax. The memory operand is inherently unsized.

1763c0ad7f Improvements to emacs packages for llvm and tablegen mode.
* Both files have valid package headers and footers (you can verify
with M-x checkdoc).
* Fixed style warnings generated by checkdoc.
* Fixed a byte-compiler warning in llvm-mode.el.
* Ensure that the modes are autoloaded, so users do not need to
(require 'llvm-mode) to use them.

f6145affbf [X86] Add OpSize32 to XBEGIN_4. Add XBEGIN_2 with OpSize16.
Requires new AsmParserOperand types that detect 16-bit and 32/64-bit mode so that we choose the right instruction based on default sizing without predicates. This is necessary since predicates mess up the disassembler table building.

71fc42dbf6 [X86] Make the instructions that use AdSize16/32/64 co-exist together without using mode predicates.
This is necessary to allow the disassembler to be able to handle AdSize32 instructions in 64-bit mode when address size prefix is used.

Eventually we should probably also support 'addr32' and 'addr16' in the assembler to override the address size on some of these instructions. But for now we'll just use special operand types that will lookup the current mode size to select the right instruction.

3bc4397f1f [X86] Remove the single AdSize indicator and replace it with separate AdSize16/32/64 flags.
This removes a hardcoded list of instructions in the CodeEmitter. Eventually I intend to remove the predicates on the affected instructions since in any given mode two of them are valid if we supported addr32/addr16 prefixes in the assembler.

74430387cd [LIT] Add JSONMetricValue type to wrap types supported by the json encoder.
Summary:
The following types can be encoded and decoded by the json library:
`dict`, `list`, `tuple`, `str`, `unicode`, `int`, `long`, `float`, `bool`, `NoneType`. 

`JSONMetricValue` can be constructed with any of these types, and used as part of Test.Result.
This patch also adds a toMetricValue function that converts a value into a MetricValue.

a4020f211b On behalf of Matthew Wahab:
An instruction alias defined with InstAlias and an optional operand in the
middle of the AsmString field, "..${a} <operands>", would get the final
"}" printed in the instruction disassembly. This wouldn't happen if the optional
operand appeared as the last item in the AsmString which is how the current
backends avoided the problem.

There don't appear to be any tests for this part of Tablegen but it passes the
pre-commit tests. Manually tested the change by enabling the generic alias
printer in the ARM backend and checking the output.

3ddc32292d [MC] Reset the MCInst in the matcher function before adding opcode/operands.
On X86, the Intel asm parser tries to match all memory operand sizes when
none is explicitly specified.  For LEA, which doesn't really have a memory
operand (just a pointer one), this results in multiple successful matches,
one for each memory size.  There's no error because it's same opcode, so
really, it's just one match.  However, the tablegen'd matcher function
adds opcode/operands to the passed MCInst, and this results in multiple
duplicated operands.

This commit clears the MCInst in the tablegen'd matcher function.
We sometimes clear it when the match failed, so there's no expectation of
keeping the previous content anyway.

We were already requiring 2.5, which meant that people on old linux distros

Requiring python 2.6 will make supporting 3.X easier as we can use the 3.X

According to the discussion on llvmdev, there is not much value is requiring
just 2.6, we may as well just require 2.7.

73ae1df82c Masked Load / Store Intrinsics - the CodeGen part.
I'm recommiting the codegen part of the patch.
The vectorizer part will be send to review again.

Masked Vector Load and Store Intrinsics.
Introduced new target-independent intrinsics in order to support masked vector loads and stores. The loop vectorizer optimizes loops containing conditional memory accesses by generating these intrinsics for existing targets AVX2 and AVX-512. The vectorizer asks the target about availability of masked vector loads and stores.
Added SDNodes for masked operations and lowering patterns for X86 code generator.
Examples:
<16 x i32> @llvm.masked.load.v16i32(i8* %addr, <16 x i32> %passthru, i32 4 /* align */, <16 x i1> %mask)
declare void @llvm.masked.store.v8f64(i8* %addr, <8 x double> %value, i32 4, <8 x i1> %mask)

Scalarizer for other targets (not AVX2/AVX-512) will be done in a separate patch.

78cc6fcb01 [Statepoints 2/4] Statepoint infrastructure for garbage collection: MI & x86-64 Backend
This is the second patch in a small series.  This patch contains the MachineInstruction and x86-64 backend pieces required to lower Statepoints.  It does not include the code to actually generate the STATEPOINT machine instruction and as a result, the entire patch is currently dead code.  I will be submitting the SelectionDAG parts within the next 24-48 hours.  Since those pieces are by far the most complicated, I wanted to minimize the size of that patch.  That patch will include the tests which exercise the functionality in this patch.  The entire series can be seen as one combined whole in http://reviews.llvm.org/D5683.

The STATEPOINT psuedo node is generated after all gc values are explicitly spilled to stack slots.  The purpose of this node is to wrap an actual call instruction while recording the spill locations of the meta arguments used for garbage collection and other purposes.  The STATEPOINT is modeled as modifing all of those locations to prevent backend optimizations from forwarding the value from before the STATEPOINT to after the STATEPOINT.  (Doing so would break relocation semantics for collectors which wish to relocate roots.)

The implementation of STATEPOINT is closely modeled on PATCHPOINT.  Eventually, much of the code in this patch will be removed.  The long term plan is to merge the functionality provided by statepoints and patchpoints.  Merging their implementations in the backend is likely to be a good starting point.

c7d3454376 Use deque<T> rather than vector<T*> since it provides the same invalidation semantics (at least when removal is not needed) without the extra indirection/ownership complexity
Order matters for this container, it seems (using a forward_list and
replacing the original push_backs with emplace_fronts caused test
failures). I didn't look too deeply into why.

(& in retrospect, I might go back & change some of the forward_lists I
introduced to deques anyway - since most don't require removal, deque is
a more memory-friendly data structure (moderate locality while not
invalidating pointers))

Pointers and references to map elements are never invalidated (except on
removal, which isn't used here) so there's no need for the indirection
unless there's polymorphism at work.

A little const correctness had to be fixed, since the indirection
allowed some benign const violations.

ae1ae2c3a1 Masked Vector Load and Store Intrinsics.
Introduced new target-independent intrinsics in order to support masked vector loads and stores. The loop vectorizer optimizes loops containing conditional memory accesses by generating these intrinsics for existing targets AVX2 and AVX-512. The vectorizer asks the target about availability of masked vector loads and stores.
Added SDNodes for masked operations and lowering patterns for X86 code generator.
Examples:
<16 x i32> @llvm.masked.load.v16i32(i8* %addr, <16 x i32> %passthru, i32 4 /* align */, <16 x i1> %mask)
declare void @llvm.masked.store.v8f64(i8* %addr, <8 x double> %value, i32 4, <8 x i1> %mask)

Scalarizer for other targets (not AVX2/AVX-512) will be done in a separate patch.

This is to be consistent with StringSet and ultimately with the standard

and then to update SmallPtrSet::insert to return pair<iterator, bool>,
and then to update all the existing users of those functions...

1d4f28c6bc Remove StringMap::GetOrCreateValue in favor of StringMap::insert
Having two ways to do this doesn't seem terribly helpful and
consistently using the insert version (which we already has) seems like
it'll make the code easier to understand to anyone working with standard
data structures. (I also updated many references to the Entry's
key and value to use first() and second instead of getKey{Data,Length,}
and get/setValue - for similar consistency)

Also removes the GetOrCreateValue functions so there's less surface area
to StringMap to fix/improve/change/accommodate move semantics, etc.

StringSet is still a bit dodgy in that it exposes the raw iterator of

actually has a 'value'... but anyway, this is useful for a handful of
clients that want to reference the newly inserted/persistent string data
in the StringSet/Map/Entry/thing.

The next step is to actually use unique_ptr in TreePatternNode's

depending on exactly how these things are handled (I have a bad
suspicion things are shared more than they should be, making this more
DAG than tree - but if it's really a tree, unique_ptr should suffice)

6536b834f8 Change order of tablegen generated fast-isel instruction code to be
based on instruction complexity

The order that tablegen fast-isel instruction code is generated is
currently based on the text of the predicate (using string
less-than). This patch changes this to instead use the instruction
complexity. Because the complexities are not unique a C++ multimap is
used instead of a map.

This fixes the problem where code with no predicate always comes out
first (the empty string always compares as less than all other
strings) thus making the code with predicates dead code. See the FMUL
code in PPCFastISel.cpp for an example. It also more closely matches
the normal codegen ordering. Some error checking in the tablegen
fast-isel code is fixed as well.

Patch by Bill Seurer.

5e4b155521 [tablegen] Add CustomCallingConv and use it to tablegen-erate the outermost parts of the Mips O32 implementation
Summary:
CustomCallingConv is simply a CallingConv that tablegen should not generate the
implementation for. It allows regular CallingConv's to delegate to these custom
functions. This is (currently) necessary for Mips and we cannot use CCCustom
without having to adapt to the different API that CCCustom uses.

This brings us a bit closer to being able to remove
MipsCC::analyzeCallOperands and MipsCC::analyzeFormalArguments in favour of
the common implementation.

No functional change to the targets.

Depends on D3341

52c08fdb90 PR21101: tablegen's FastISel emitter should filter out unused functions.
FastISel has a fixed set of virtual functions that are overridden by the
tablegen-generated code for each target. These functions are distinguished by
the kinds of operands, e.g., register + immediate = "ri". The FastISel emitter
has been blindly emitting functions with different combinations of operand
kinds, even for combinations that are completely unused by FastISel, e.g.,
"fastEmit_rrr". Change to filter out functions that will be irrelevant for
FastISel and do not bother generating the code for them. Also add explicit
"override" keywords for the virtual functions that are overridden.

03fe69e90d [mips] Add CCValAssign::[ASZ]ExtUpper and CCPromoteToUpperBitsInType and handle struct's correctly on big-endian N32/N64 return values.
Summary:
The N32/N64 ABI's require that structs passed in registers are laid out
such that spilling the register with 'sd' places the struct at the lowest
address. For little endian this is trivial but for big-endian it requires
that structs are shifted into the upper bits of the register.

We also require that structs passed in registers have the 'inreg'
attribute for big-endian N32/N64 to work correctly. This is because the
tablegen-erated calling convention implementation only has access to the
lowered form of struct arguments (one or more integers of up to 64-bits
each) and is unable to determine the original type.

7cd7154421 [x86] Fix a pretty horrible bug and inconsistency in the x86 asm
parsing (and latent bug in the instruction definitions).

This is effectively a revert of r136287 which tried to address
a specific and narrow case of immediate operands failing to be accepted
by x86 instructions with a pretty heavy hammer: it introduced a new kind
of operand that behaved differently. All of that is removed with this
commit, but the test cases are both preserved and enhanced.

The core problem that r136287 and this commit are trying to handle is
that gas accepts both of the following instructions:

  insertps $192, %xmm0, %xmm1
  insertps $-64, %xmm0, %xmm1

These will encode to the same byte sequence, with the immediate
occupying an 8-bit entry. The first form was fixed by r136287 but that
broke the prior handling of the second form! =[ Ironically, we would
still emit the second form in some cases and then be unable to
re-assemble the output.

The reason why the first instruction failed to be handled is because
prior to r136287 the operands ere marked 'i32i8imm' which forces them to
be sign-extenable. Clearly, that won't work for 192 in a single byte.
However, making thim zero-extended or "unsigned" doesn't really address
the core issue either because it breaks negative immediates. The correct
fix is to make these operands 'i8imm' reflecting that they can be either
signed or unsigned but must be 8-bit immediates. This patch backs out
r136287 and then changes those places as well as some others to use
'i8imm' rather than one of the extended variants.

Naturally, this broke something else. The custom DAG nodes had to be
updated to have a much more accurate type constraint of an i8 node, and
a bunch of Pat immediates needed to be specified as i8 values.

The fallout didn't end there though. We also then ceased to be able to
match the instruction-specific intrinsics to the instructions so
modified. Digging, this is because they too used i32 rather than i8 in
their signature. So I've also switched those intrinsics to i8 arguments
in line with the instructions.

In order to make the intrinsic adjustments of course, I also had to add
auto upgrading for the intrinsics.

I suspect that the intrinsic argument types may have led everything down
this rabbit hole. Pretty happy with the result.

ARM in particular is getting dangerously close to exceeding 32 bits worth of

Mostly just refactoring at present, and there's probably no way to test.

Summary:
This patch changes the way xfail and unsupported tests are displayed. 
This output is only displayed when the --show-unsupported/--show-xfail flags are passed to lit.

Currently xfail/unsupported tests are printed during the run of the test-suite. I think its better to display this information during the summary instead.
This patch removes the printing of these tests from when they are run to the summary.

adc58a657b [shuffle] Stand back! I'm about to (try to) do math!
Especially with blends and large tree heights there was a problem with
the fuzzer where it would end up with enough undef shuffle elements in
enough parts of the tree that in a birthday-attack kind of way we ended
up regularly having large numbers of undef elements in the result. I was
seeing reasonably frequent cases of *all* results being undef which
prevents us from doing any correctness checking at all. While having
undef lanes is important, this was too much.

So I've tried to apply some math to the probabilities of having an undef
lane and balance them against the tree height. Please be gentle, I'm
really terrible at math. I probably made a bunch of amateur mistakes
here. Fixes, etc. are quite welcome. =D At least in running it some, it
seems to be producing more interesting (for correctness testing)
results.

This required a pretty substantial rewrite of the innards. The number of
shuffle instructions is now bounded in terms of tree-height. There is
a flag to disable blends so that its still possible to test single input
shuffles. I've also improved various aspects of how the test program is
generated, primarily to simplify the test harness and allow some
optimizations to clean up how we actually check the results and build up
the inputs.

b7c9534f75 FileCheck: Add a flag to allow checking empty input
Currently FileCheck errors out on empty input. This is usually the
right thing to do, but makes testing things like "this command does
not emit some error message" hard to test. This usually leads to
people using "command 2>&1 | count 0" instead, and then the bots that
use guard malloc fail a few hours later.

By adding a flag to FileCheck that allows empty inputs, we can make
tests that consist entirely of "CHECK-NOT" lines feasible.

81dfaefc4c Add a vector shuffle fuzzer.
This is a python script which for a given seed generates a random
sequence of random shuffles of a random vector width. It embeds this
into a function and emits a main function which calls the test routine
and checks that the results (where defined) match the obvious results.

I'll be using this to drive out miscompiles from the new vector shuffle
logic now that it is clean of any crashes I can find with llvm-stress.

Note, my python skills are very poor. Sorry if this is terrible code,
and feel free to tell me how I should write this or just patch it as
necessary.

The tests generated try to be very portable and use boring C routines.
It technically will mis-declare the C routines and pass 32-bit integers
to parametrs that expect 64-bit integers. If someone wants to fix this
and has less terrible ideas of how to do it, I'm all ears. Fortunately,
this "just works" for x86. =]

bcf8459a40 Add a small utility called bisect that enables commandline bisecting on a counter.
This is something that I have found to be very useful in my work and I
wanted to contribute it back to the community since several people in
the past have asked me for something along these lines. (Jakob, I know
this has been a while coming ; )]

The way you use this is you create a script that takes in as its first
argument a count. The script passes into LLVM the count via a command
line flag that disables a pass after LLVM has run after the pass has
run for count number of times. Then the script invokes a test of some
sort and indicates whether LLVM successfully compiled the test via the
scripts exit status. Then you invoke bisect as follows:

bisect --start=<start_num> --end=<end_num> ./script.sh "%(count)s"

And bisect will continually call ./script.sh with various counts using
the exit status to determine success and failure.

that stand-alone patterns set a larger AddedComplexity value, which
can be confusing to new developers, the allows us to reduce the

independent node and pseudo instruction which gets expanded post-RA to a

can now just remat the value when it can't keep it in a register.

This is useful for cases when stand-alone patterns are preferred to the
patterns included in the instruction definitions.  Instead of requiring
that stand-alone patterns set a larger AddedComplexity value, which
can be confusing to new developers, the allows us to reduce the
complexity of the included patterns to achieve the same result.

ec31a302b7 Remove uses of the redundant ".reset(nullptr)" of unique_ptr, in favor of ".reset()"
It's also possible to just write "= nullptr", but there's some question
of whether that's as readable, so I leave it up to authors to pick which
they prefer for now. If we want to discuss standardizing on one or the
other, we can do that at some point in the future.

f7e042324a Move Post RA Scheduling flag bit into SchedMachineModel
Refactoring; no functional changes intended

    Removed PostRAScheduler bits from subtargets (X86, ARM).
    Added PostRAScheduler bit to MCSchedModel class.
    This bit is set by a CPU's scheduling model (if it exists).
    Removed enablePostRAScheduler() function from TargetSubtargetInfo and subclasses.
    Fixed the existing enablePostMachineScheduler() method to use the MCSchedModel (was just returning false!).
    Added methods to TargetSubtargetInfo to allow overrides for AntiDepBreakMode, CriticalPathRCs, and OptLevel for PostRAScheduling.
    Added enablePostRAScheduler() function to PostRAScheduler class which queries the subtarget for the above values.
    Preserved existing scheduler behavior for ARM, MIPS, PPC, and X86: 
       a. ARM overrides the CPU's postRA settings by enabling postRA for any non-Thumb or Thumb2 subtarget. 
       b. MIPS overrides the CPU's postRA settings by enabling postRA for everything. 
       c. PPC overrides the CPU's postRA settings by enabling postRA for everything. 
       d. X86 is the only target that actually has postRA specified via sched model info.

c58b079d23 Add FileCheck -implicit-check-not option to allow stricter tests without adding too many CHECK-NOTs manually.
Summary:
Add FileCheck -implicit-check-not option which allows specifying a
pattern that should only occur in the input when explicitly matched by a
positive check. This feature allows checking tool diagnostics in a way
clang -verify does it for compiler diagnostics.

The option has been tested on a number of clang-tidy checks, I'll post a link to
the clang-tidy patch to this thread.

Once there's an agreement on the general direction, I can add tests and
documentation.

bb5f6229f4 TableGen: introduce support for MSBuiltin
Add MSBuiltin which is similar in vein to GCCBuiltin.  This allows for adding
intrinsics for Microsoft compatibility to individual instructions.  This is
needed to permit the creation of ARM specific MSVC extensions.

This is not currently in use, and requires an associated change in clang to
enable use of the intrinsics defined by this new class.  This merely sets the
LLVM portion of the infrastructure in place to permit the use of this
functionality.  A separate set of changes will enable the new intrinsics.

2559070422 Introduce a string_ostream string builder facilty
string_ostream is a safe and efficient string builder that combines opaque
stack storage with a built-in ostream interface.

small_string_ostream<bytes> additionally permits an explicit stack storage size
other than the default 128 bytes to be provided. Beyond that, storage is
transferred to the heap.

This convenient class can be used in most places an
std::string+raw_string_ostream pair or SmallString<>+raw_svector_ostream pair
would previously have been used, in order to guarantee consistent access
without byte truncation.

The patch also converts much of LLVM to use the new facility. These changes
include several probable bug fixes for truncated output, a programming error
that's no longer possible with the new interface.

7acd886ecf Use std::error_code instead of llvm::error_code.
The idea of this patch is to turn llvm/Support/system_error.h into a
transitional header that just brings in the erorr_code api to the llvm
namespace. I will remove it shortly afterwards.

The cases where the general idea needed some tweaking:

* std::errc is a namespace in msvc, so we cannot use "using std::errc". I could
add an #ifdef, but there were not that many uses, so I just added std:: to
them in this patch.

* Template specialization had to be moved to the std namespace in this
patch set already.

* The msvc implementation of default_error_condition doesn't seem to
provide the same transformations as we need. Not too surprising since
the standard doesn't actually say what "equivalent" means. I fixed the
problem by keeping our old mapping and using it at error_code
construction time.

Despite these shortcomings I think this is still a good thing. Some reasons:

* The different implementations of system_error might improve over time.
* It removes 925 lines of code from llvm already.
* It removes 6313 bytes from the text segment of the clang binary when
it is built with gcc and 2816 bytes when building with clang and
libstdc++.

e072ed71c8 ARM64: separate load/store operands to simplify assembler
This changes ARM64 to use separate operands for each component of an
address, and look for separate '[', '$Rn, ..., ']' tokens when
parsing.

This allows us to do away with quite a bit of special C++ code to
handle monolithic "addressing modes" in the MC components. The more
incremental matching of the assembler operands also allows for better
diagnostics when LLVM is presented with invalid input.

Most of the complexity here is with the register-offset instructions,
which were extremely dodgy beforehand: even when the instruction used
wM, LLVM's model had xM as an operand. We papered over this
discrepancy before, but that approach doesn't work now so I split them
into separate X and W variants.

3046dcbce4 [asm matcher] Fix incorrect assertion when there are exactly 32 SubtargetFeatures
Summary:
The minimal type needs to hold a value of '1ULL << 31' but
getMinimalTypeForRange() is called with a value of '1ULL << 32'.

This patch will also reduce the size of the matcher table when there are 8
or 16 SubtargetFeatures.

Also added a dump of the SubtargetFeatures to the -debug output and corrected getMinimalTypeInRange() to consider 0xffffffffull to be a 32-bit value.

The testcase is that no existing code is broken and that LLVM still successfully
compiles after adding MIPS64r6 CodeGen support.

ee8d5c393e TableGen: permit non-leaf ComplexPattern uses
This allows the results of a ComplexPattern check to be distributed to separate
named Operands, instead of the current system where all results must apply (and
match perfectly) with a single Operand.

For example, if "some_addrmode" is a ComplexPattern producing two results, you
can write:

   def : Pat<(load (some_addrmode GPR64:$base, imm:$offset)),
             (INST GPR64:$base, imm:$offset)>;

This should allow neater instruction definitions in TableGen that don't put all
possible aspects of addressing into a single operand, but are still usable with
relatively simple C++ CodeGen idioms.

c9ff20e8c6 TableGen: convert InstAlias's Emit bit to an int.
When multiple aliases overlap, the correct string to print can often be
determined purely by considering the InstAlias declarations in some particular
order. This allows the user to specify that order manually when desired,
without resorting to hacking around with the default lexicographical order on
Record instantiation, which is error-prone and ugly.

I was also mistaken about "add w2, w3, w4" being the same as "add w2, w3, w4,
uxtw". That's only true if Rn is the stack pointer.

a9a94ce839 TableGen: fix operand counting for aliases
TableGen has a fairly dubious heuristic to decide whether an alias should be
printed: does the alias have lest operands than the real instruction. This is
bad enough (particularly with no way to override it), but it should at least be
calculated consistently for both strings.

This patch implements that logic: first get the *correct* string for the
variant, in the same way as the Matcher, without guessing; then count the
number of whitespace chars.

There are basically 4 changes this brings about after the previous
commits; all of these appear to be good, so I have changed the tests:

+ ARM64: we print "neg X, Y" instead of "sub X, xzr, Y".
+ ARM64: we skip implicit "uxtx" and "uxtw" modifiers.
+ Sparc: we print "mov A, B" instead of "or %g0, A, B".
+ Sparc: we print "fcmpX A, B" instead of "fcmpX %fcc0, A, B"

d0e93f2440 TableGen: use correct MIOperand when printing aliases
Previously, TableGen assumed that every aliased operand consumed precisely 1
MachineInstr slot (this was reasonable because until a couple of days ago,
nothing more complicated was eligible for printing).

This allows a couple more ARM64 aliases to print so we can remove the special
code.

On the X86 side, I've gone for explicit AT&T size specifiers as the default, so
turned off a few of the aliases that would have just started printing.
