Duncan P. N. Exon Smith 286d94884b CodeGen: Use MachineInstr& in PostRAHazardRecognizer, NFC
Convert a loop to a range-based for, using MachineInstr& instead of
MachineInstr* and removing an implicit conversion from iterator to
pointer.

Duncan P. N. Exon Smith 6e3ac34202 CodeGen: Use MachineInstr& in PrologEpilogInserter, NFC
Use MachineInstr& over MachineInstr* to avoid implicit iterator to
pointer conversions.  MachineInstr*-as-nullptr was being used as a flag
for whether the for loop terminated normally; I added an explicit `bool`
instead.

Matt Arsenault d7e8898bdd LoadStoreVectorizer: if one element of a vector is integer, default to
integer.

Fixes issues on some architectures where we use arithmetic ops to build
vectors, which can cause bad things to happen for loads/stores of mixed
types.

Sebastian Pop 5c5798c57c code hoisting pass based on GVN
This pass hoists duplicated computations in the program. The primary goal of
gvn-hoist is to reduce the size of functions before inline heuristics to reduce
the total cost of function inlining.

Pass written by Sebastian Pop, Aditya Kumar, Xiaoyu Hu, and Brian Rzycki.

Duncan P. N. Exon Smith 632987296f Target: Remove unused arguments from overrideSchedPolicy, NFC
TargetSubtargetInfo::overrideSchedPolicy takes two MachineInstr*
arguments (begin and end) that invite implicit conversions from
MachineInstrBundleIterator.  One option would be to change their type to
an iterator, but since they don't seem to have been used since the API
was added in 2010, I'm deleting the dead code.

Vassil Vassilev 488b3bde3d [CMake] Module builds depend on target intrinsics_gen to be built first.
When compiling with modules, header A and B can be in the same module M.
B depends on intrinsics_gen and A doesn't. Compiling a source file #include-ing
header A, we implicitly request module M to be built. It puts header A and B in
the same TU and tries to build them. Since B depends on intrinsics_gen (which
might not be built yet) we run into build failures.

This should fix our modules buildbot.

Chandler Carruth 3629343d2b Introduce a *draft* of a code of conduct for the LLVM community and the
associated reporting guide.

I want to emphasize that at this point these are just drafts!

This is the result of very extended discussion on the mailing lists on
several different threads:
http://lists.llvm.org/pipermail/llvm-dev/2015-October/091218.html
http://lists.llvm.org/pipermail/llvm-dev/2016-May/099120.html
http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20151019/307070.html

The reporting guide in particular I anticipate will be shaped somewhat
by the advisory committee when they are selected. But hopefully this
serves as a good starting point and good guidance while the advisory
committee is being sorted out.

I'd like to thank all the folks who contributed to this. Many, *many*
people worked to help with drafting, wording, suggestions, and edits.
Also, this is based on widely used existing codes of coduct as mentioned
in the text, and the original authors of those deserve many thanks as
well.

This is fairly similar to a SetVector, but helps in the case where in
addition to not inserting duplicates you want to adjust the sequence of

I'm not at all attached to the name of this data structure if others
have better suggestions, but this is one that David Majnemer brought up
in IRC discussions that seems plausible.

I've trimmed the interface down somewhat from SetVector's interface
because several things make less sense here IMO: iteration primarily.

Duncan P. N. Exon Smith 9cfc75c214 CodeGen: Use MachineInstr& in TargetInstrInfo, NFC
This is mostly a mechanical change to make TargetInstrInfo API take
MachineInstr& (instead of MachineInstr* or MachineBasicBlock::iterator)
when the argument is expected to be a valid MachineInstr.  This is a
general API improvement.

Although it would be possible to do this one function at a time, that
would demand a quadratic amount of churn since many of these functions
call each other.  Instead I've done everything as a block and just
updated what was necessary.

This is mostly mechanical fixes: adding and removing `*` and `&`
operators.  The only non-mechanical change is to split
ARMBaseInstrInfo::getOperandLatencyImpl out from
ARMBaseInstrInfo::getOperandLatency.  Previously, the latter took a
`MachineInstr*` which it updated to the instruction bundle leader; now,
the latter calls the former either with the same `MachineInstr&` or the
bundle leader.

As a side effect, this removes a bunch of MachineInstr* to
MachineBasicBlock::iterator implicit conversions, a necessary step
toward fixing PR26753.

Note: I updated WebAssembly, Lanai, and AVR (despite being
off-by-default) since it turned out to be easy.  I couldn't run tests
for AVR since llc doesn't link with it turned on.

memory buffers added to the archive must be stored within an Archive::Member,
which must have an associated Archive. This makes it harder than necessary
to create new archive members (or new archives entirely) from scratch using
memory buffers.

This patch replaces NewArchiveIterator with a NewArchiveMember class that
stores just the memory buffer and the information that goes into the archive
member header.

Zachary Turner 07670b3e98 Resubmit "Update llvm command line parser to support subcommands."
This fixes an issue where occurrence counts would be unexpectedly
reset when parsing different parts of a command line multiple
times.

**ORIGINAL COMMIT MESSAGE**

This allows command line tools to use syntaxes like the following:

      llvm-foo.exe command1 -o1 -o2
      llvm-foo.exe command2 -p1 -p2

Where command1 and command2 contain completely different sets of
valid options.  This is backwards compatible with previous uses
of llvm cl which did not support subcommands, as any option
which specifies no optional subcommand (e.g. all existing
code) goes into a special "top level" subcommand that expects
dashed options to appear immediately after the program name.
For example, code which is subcommand unaware would generate
a command line such as the following, where no subcommand
is specified:

      llvm-foo.exe -q1 -q2

The top level subcommand can co-exist with actual subcommands,
as it is implemented as an actual subcommand which is searched
if no explicit subcommand is specified.  So llvm-foo.exe as
specified above could be written so as to support all three
aforementioned command lines simultaneously.

There is one additional "special" subcommand called AllSubCommands,
which can be used to inject an option into every subcommand.
This is useful to support things like help, so that commands
such as:

      llvm-foo.exe --help
      llvm-foo.exe command1 --help
      llvm-foo.exe command2 --help

All work and display the help for the selected subcommand
without having to explicitly go and write code to handle each
one separately.

This patch is submitted without an example of anything actually
using subcommands, but a followup patch will convert the
llvm-pdbdump tool to use subcommands.

This is a fix for PR27842.

An IR-level implementation of stack coloring tailored to work with
SafeStack. It is a bit weaker than the MI implementation in that it
does not the "lifetime start at first access" logic. This can be
improved in the future.

This patch also replaces the naive implementation of stack frame

Rafael Espindola 2211f015cc Don't verify inputs to the Linker if ODR merging.
This fixes pr28072.

The point, as Duncan pointed out, is that the file is already
partially linked by just reading it.

Long term I think the solution is to make metadata owned by the module
and then the linker will lazily read it and be in charge of all the
linking. Running a verifier in each input will defeat the lazy
loading, but will be legal.

Right now we are at the unfortunate position that to support odr
merging we cannot verify the inputs, which mildly annoying (see test

I found this deficiency while playing around with a loop in the x86 backend that contained a signed division that could be optimized into an unsigned division if we could prove both inputs were positive. One of them being the loop induction variable. With this patch we can perform the conversion for this case. One of the test cases here is a contrived variation of the loop I was looking at.

Kevin Enderby 42398051d8 Finish cleaning up most of the error handling in libObject’s MachOUniversalBinary
and its clients to use the new llvm::Error model for error handling.

Changed getAsArchive() from ErrorOr<...> to Expected<...> so now all
interfaces there use the new llvm::Error model for return values.

In the two places it had if (!Parent) this is actually a program error so changed
from returning errorCodeToError(object_error::parse_failed) to calling
report_fatal_error() with a message.

In getObjectForArch() added error messages to its two llvm::Error return values
instead of returning errorCodeToError(object_error::arch_not_found) with no
error message.

For the llvm-obdump, llvm-nm and llvm-size clients since the only binary files in
Mach-O Universal Binaries that are supported are Mach-O files or archives with
Mach-O objects, updated their logic to generate an error when a slice contains
something like an ELF binary instead of ignoring it. And added a test case for
that.

The last error stuff to be cleaned up for libObject’s MachOUniversalBinary is
the use of errorOrToExpected(Archive::create(ObjBuffer)) which needs
Archive::create() to be changed from ErrorOr<...> to Expected<...> first,
which I’ll work on next.

However, the actual immediate value is small enough and not need to be hoisted.

Chris Bieneman 92b2e8a295 [YAML] Fix YAML tags appearing before the start of sequence elements
Our existing yaml::Output code writes tags immediately when mapTag is called, without any state handling. This results in tags on sequence elements being written before the element itself. For example, we see this:

SomeArray:     !elem_type
  - key1:         1
    key2:         2 !elem_type2
  - key3:         3
    key4:         4

We should instead see:

SomeArray:
  - !elem_type
    key1:         1
    key2:         2
  - !elem_type2
    key3:         3
    key4:         4

Our reader handles reading properly, so this bug only impacts writing yaml sequences with tagged elements.

As a test for this I've modified the Mach-O yaml encoding to allways apply the !mach-o tag when encoding MachOYAML::Object entries. This results in the !mach-o tag appearing as expected in dumped fat files.

Zachary Turner 2012d744f4 Update llvm command line parser to support subcommands.
This allows command line tools to use syntaxes like the following:

  llvm-foo.exe command1 -o1 -o2
  llvm-foo.exe command2 -p1 -p2

Where command1 and command2 contain completely different sets of
valid options.  This is backwards compatible with previous uses
of llvm cl which did not support subcommands, as any option
which specifies no optional subcommand (e.g. all existing
code) goes into a special "top level" subcommand that expects
dashed options to appear immediately after the program name.
For example, code which is subcommand unaware would generate
a command line such as the following, where no subcommand
is specified:

  llvm-foo.exe -q1 -q2

The top level subcommand can co-exist with actual subcommands,
as it is implemented as an actual subcommand which is searched
if no explicit subcommand is specified.  So llvm-foo.exe as
specified above could be written so as to support all three
aforementioned command lines simultaneously.

There is one additional "special" subcommand called AllSubCommands,
which can be used to inject an option into every subcommand.
This is useful to support things like help, so that commands
such as:

  llvm-foo.exe --help
  llvm-foo.exe command1 --help
  llvm-foo.exe command2 --help

All work and display the help for the selected subcommand
without having to explicitly go and write code to handle each
one separately.

This patch is submitted without an example of anything actually
using subcommands, but a followup patch will convert the
llvm-pdbdump tool to use subcommands.

Artur Pilipenko 7ad95ec22d Support arbitrary addrspace pointers in masked load/store intrinsics
This is a resubmittion of 263158 change after fixing the existing problem with intrinsics mangling (see LTO and intrinsics mangling llvm-dev thread for details).

This patch fixes the problem which occurs when loop-vectorize tries to use @llvm.masked.load/store intrinsic for a non-default addrspace pointer. It fails with "Calling a function with a bad signature!" assertion in CallInst constructor because it tries to pass a non-default addrspace pointer to the pointer argument which has default addrspace.

The fix is to add pointer type as another overloaded type to @llvm.masked.load/store intrinsics.

Simon Pilgrim 5f71c909f0 [X86][AVX] Peek through bitcasts to find the source of broadcasts (reapplied)
AVX1 can only broadcast vectors as floats/doubles, so for 256-bit vectors we insert bitcasts if we are shuffling v8i32/v4i64 types. Unfortunately the presence of these bitcasts prevents the current broadcast lowering code from peeking through cases where we have concatenated / extracted vectors to create the 256-bit vectors.

This patch allows us to peek through bitcasts as long as the number of elements doesn't change (i.e. element bitwidth is the same) so the broadcast index is not affected.

Note this bitcast peek is different from the stage later on which doesn't care about the type and is just trying to find a load node.

As we're being more aggressive with bitcasts, we also need to ensure that the broadcast type is correctly bitcasted

Simon Pilgrim c15d217831 [X86][SSE] Added support for combining target shuffles to (V)PSHUFD/VPERMILPD/VPERMILPS immediate permutes
This patch allows target shuffles to be combined to single input immediate permute instructions - (V)PSHUFD/VPERMILPD/VPERMILPS - allowing more general pattern matching than what we current do and improves the likelihood of memory folding compared to existing patterns which tend to reuse the input in multiple arguments.

Further permute instructions (V)PSHUFLW/(V)PSHUFHW/(V)PERMQ/(V)PERMPD may be added in the future but its proven tricky to create tests cases for them so far. (V)PSHUFLW/(V)PSHUFHW is already handled quite well in combineTargetShuffle so it may be that removing some of that code may allow us to perform more of the combining in one place without duplication.

Instead of requiring --format, it infers the format based on the tags found in the object file. The supported tags are:

!ELF
!COFF
!mach-o
!fat-mach-o

I have a corresponding patch that is quite large that fixes up all the in-tree test cases.

Artur Pilipenko a36aa41519 Support arbitrary addrspace pointers in masked load/store intrinsics
This is a resubmittion of 263158 change after fixing the existing problem with intrinsics mangling (see LTO and intrinsics mangling llvm-dev thread for details).

This patch fixes the problem which occurs when loop-vectorize tries to use @llvm.masked.load/store intrinsic for a non-default addrspace pointer. It fails with "Calling a function with a bad signature!" assertion in CallInst constructor because it tries to pass a non-default addrspace pointer to the pointer argument which has default addrspace.

The fix is to add pointer type as another overloaded type to @llvm.masked.load/store intrinsics.

Kuba Brecka 7d03ce480a [asan] fix false dynamic-stack-buffer-overflow report with constantly-sized dynamic allocas, LLVM part
See the bug report at https://github.com/google/sanitizers/issues/691. When a dynamic alloca has a constant size, ASan instrumentation will treat it as a regular dynamic alloca (insert calls to poison and unpoison), but the backend will turn it into a regular stack variable. The poisoning/unpoisoning is then broken. This patch will treat such allocas as static.

Renato Golin ef3eb066a9 [ARM] Fix Thumb text sections' flags under COFF/Windows
The main issue here is that the "thumb" flag wasn't set for some of these
sections, making MSVC's link.exe fails to correctly relocate code
against the symbols inside these sections. link.exe could fail for
instance with the "fixup is not aligned for target 'XX'" error. If
linking doesn't fail, the relocation process goes wrong in the end and
invalid code is generated by the linker.

This patch adds Thumb/ARM information so that the right flags are set
on COFF/Windows.

  *to++ = *from++;

I use getPtrStride() to find Stride for memory access and return 0 is the Stride is not 1 or -1.

Simon Pilgrim a45da385f8 [X86][AVX] Peek through bitcasts to find the source of broadcasts
AVX1 can only broadcast vectors as floats/doubles, so for 256-bit vectors we insert bitcasts if we are shuffling v8i32/v4i64 types. Unfortunately the presence of these bitcasts prevents the current broadcast lowering code from peeking through cases where we have concatenated / extracted vectors to create the 256-bit vectors.

This patch allows us to peek through bitcasts as long as the number of elements doesn't change (i.e. element bitwidth is the same) so the broadcast index is not affected.

Note this bitcast peek is different from the stage later on which doesn't care about the type and is just trying to find a load node.
