Mehdi Amini b550cb1750 [NFC] Header cleanup
Removed some unused headers, replaced some headers with forward class declarations.

Found using simple scripts like this one:
clear && ack --cpp -l '#include "llvm/ADT/IndexedMap.h"' | xargs grep -L 'IndexedMap[<]' | xargs grep -n --color=auto 'IndexedMap'

Craig Topper 6ff46266d1 Declare MVT::SimpleValueType as an int8_t sized enum. This removes 400 bytes from TargetLoweringBase and probably other places.
This required changing several places to print VT enums as strings instead of raw ints since the proper method to use to print became ambiguous. This is probably an improvement anyway.

This also appears to save ~8K from an x86 self host build of llc.

Richard Smith 2db6f2e508 Update and fix LLVM_ENABLE_MODULES:
1) We need to add this flag prior to adding any other, in case the user has
specified a -fmodule-cache-path= flag in their custom CXXFLAGS. Such a flag
causes -Werror builds to fail, and thus all config checks fail, until we add
the corresponding -fmodules flag. The modules selfhost bot does this, for
instance.

2) Delete module maps that were putting .cpp files into modules.

3) Enable -fmodules-local-submodule-visibility, to get proper module
visibility rules applied across submodules of the same module. Disable
-fmodules for C builds, since that flag is not available there.

Sanjay Patel 96241e78ed check or check-next the first line of the function too
We could make this an option if people don't like it. 
But since part of the reason for using a script to generate
checks is to prevent lazy checking that lets bugs crawl 
through, let's have the script check the first line too. 

For asm tests, it ensures that nothing unexpected has 
happened before the first line of asm. This matches the
existing behavior of update_llc_test_checks.py.

Daniel Dunbar 42881eac30 [lit][googletest] Handle upstream gtest output
Summary:
Upstream googletest prints "Running main() from gtest_main.cc" to stdout prior
to running tests. LLVM removed that print statement in r61540. If a user were
to use lit to run tests that use upstream googletest, however, lit
reports "Running main()" as an invalid test name.

To avoid such a failure, add an extra conditional to `formats/googletest.py`.
Also add tests to demonstrate the modified behavior.

Sanjay Patel fff7a3d0ef Add utility script to generate checks for opt or llc regression tests
This is an enhancement of the existing update_llc_test_checks.py script.
It adds some of the functionality from the script used in D17999 to make
the IR checking more flexible.

The bad news: 
This actually is 'My First Python Program'. Thus, it's likely that I have
violated all best practices of Python programming if I've made a functional
change from the original program. If you see anything that's obviously 
wrong, please let me know or feel free to fix it. I didn't even read any
documentation...

The good news: 
I tested this on ~10 existing opt/llc regression tests, and it does what 
I hoped for. It produces exact checking for IR regression tests and doesn't
signficantly change the existing llc-with-x86-target asm checking. The opt
tests that were modified in r263667, r263668, r263674, and r263679 are
examples of the expected results, except that this version of the script 
puts the check lines ahead of the IR to follow the existing llc/asm 
behavior.

If there are no complaints/fallout, we should be able to remove the 
original script. Extending this script to be used for non-x86 and clang
regression tests would be the expected follow-up steps.

Sanjay Patel 506fd0d81d don't hardcode the name of the llc checks script
We lose the 'utils' directory name in our advertising line with
this change. We could retain that, but I don't see the point.
This removes a dependency for making the script apply to more than
'llc'. Ie, we'll want to change the script name if it works with 
opt/clang too.

TableGen checks at compiletime that for scheduling models with
"CompleteModel = 1" one of the following holds:

- Is marked with the hasNoSchedulingInfo flag
- The instruction is a subclass of Sched
- There are InstRW definitions in the scheduling model

Typical steps necessary to complete a model:

- Ensure all pseudo instructions that are expanded before machine
  scheduling (usually everything handled with EmitYYY() functions in
  XXXTargetLowering).
- If a CPU does not support some instructions mark the corresponding
  resource unsupported: "WriteRes<WriteXXX, []> { let Unsupported = 1; }".
- Add missing scheduling information.

Nikolay Haustov ea8febde04 [TableGen] AsmMatcher: Skip optional operands in the midle of instruction if it is not present
Previosy, if actual instruction have one of optional operands then other optional operands listed before this also should be presented.
For example instruction v_fract_f32 v0, v1, mul:2 have one optional operand - OMod and do not have optional operand clamp. Previously this was not allowed because clamp is listed before omod in AsmString:

string AsmString = "v_fract_f32$vdst, $src0_modifiers$clamp$omod";
Making this work required some hacks (both OMod and Clamp match classes have same PredicateMethod).

Now, if MatchInstructionImpl meets formal optional operand that is not presented in actual instruction it skips this formal operand and tries to match current actual operand with next formal.

Reid Kleckner 45b6159ed3 Minor performance tweaks to llvm-tblgen (and a few that might be a good idea)
Summary:
This patch adds a reserve call to an expensive function
(`llvm::LoadIntrinsics`), and may fix a few other low hanging
performance fruit (I've put them in comments for now, so we can
discuss).

**Motivation:**

As I'm sure other developers do, when I build LLVM, I build the entire
project with the same config (`Debug`, `MinSizeRel`, `Release`, or
`RelWithDebInfo`). However, the `Debug` config also builds llvm-tblgen
in `Debug` mode. Later build steps that run llvm-tblgen then can
actually be the slowest steps in the entire build. Nobody likes slow
builds.

Summary:
This adds a new attribute which targets can set in TableGen which causes a function to be generated which matches register alternative names. This is very similar to `ShouldEmitMatchRegisterName`, except it works on alt names.

This patch is currently used by the out of tree part of the AVR backend. It reduces code duplication greatly, and has the effect that you do not need to hardcode altname to register mappings in C++.

It will not work on targets which have registers which share the same aliases.

Daniel Sanders 20de54bc94 Bring back the test-suite export in test-release without bringing back the build failures.
Summary:
r257791 disabled the test-suite export since the addition of CMakeLists.txt was
causing build failures. This patch exports the test-suite again but does so
outside the source tree so that it isn't included in the Phase[123] builds.

Yunzhong Gao 192bdf884d Add "/dev/tty" as a special file name for lit tests.
If a lit test has a RUN line that includes a redirection to "/dev/tty", the
redirection goes to the special device file corresponding to the console. It
is /dev/tty on UNIX-like systems and "CON" on Windows.

This patch is needed to implement a test like PR25717 (caused by the size limit
of the Windows system call WriteConsole() prior to Windows 8) where the test
only breaks when outputing to the console and won't fail if using a pipe.

Reid Kleckner 5b4637141e [llvm-tblgen] Avoid StringMatcher for GCC and MS builtin names
This brings the compile time of Function.cpp from ~40s down to ~4s for
me locally. It also shaves off about 400KB of object file size in a
release+asserts build.

I also realized that the AMDGPU backend does not have any GCC builtin
names to match, so the extra lookup was a no-op. I removed it to silence
a zero-length string table array warning. There should be no functional
change here.

This change really ends the story of PR11951.

Hans Wennborg 6c52b02e7d test-release.sh: Ignore LC_CTYPE in sed invocation on Darwin
Here, sed is used to prepare object files for comparison via cmp. On my Darwin
15.4.0 machine, LC_CTYPE is set to UTF-8 (by default, I believe). Under these
circumstances, anything sed is made to read will be treated as UTF-8, prompting
it to signal an error if it is not, like so:

% sed s/a/b/ <(head -n1 /dev/random) >/dev/null; echo $?
sed: RE error: illegal byte sequence
1
%

To make sed work as expected, I need to set LC_CTYPE to C:

% env LC_CTYPE=C sed s/a/b/ <(head -n1 /dev/random) >/dev/null; echo $?
0
%

Without this change, sed will exit with an error for every single file that it
compares between phase 2 and phase 3, thereby making it look as if the
differences were far larger than they are.

Reid Kleckner 86ff2689a5 Sort intrinsics by LLVM intrinsic name, rather than tablegen def name
Step one towards using a simple binary search to lookup intrinsic IDs
instead of our crazy table generated switch+memcmp+startswith code that
makes Function.cpp take about a minute to compile.  See PR24785 and
PR11951 for why we should do this.

The X86 backend contains tables that need to be sorted on intrinsic ID,
so reorder those.

Oliver Stannard 7772f023b5 [TableGen] Fix sort order of asm operand classes
This is a fix for https://llvm.org/bugs/show_bug.cgi?id=22796.

The previous implementation of ClassInfo::operator< allowed cycles of classes
such that x < y < z < x, meaning that a list of them cannot be correctly
sorted, and the sort order could differ with different standard libraries.

The original implementation sorted classes by ValueName if they were otherwise
equal. This isn't strictly necessary, but some backends seem to accidentally
rely on it. If I reverse this comparison I get 8 test failures spread across
the AArch64, Mips and X86 backends, so I have left it in until those backends
can be fixed.

There was one case in the X86 backend where the observable behaviour of the
assembler is changed by this patch. This was because some of the memory asm
operands were not marked as children of X86MemAsmOperand.

Summary:
In the past I have run into several problems with the way
`test-release.sh` creates all the subproject directories as siblings,
and then uses symlinks to stitch them all together.  In some scenarios
this leads to clang not being able to find header files, etc.

This patch changes the script so it directly exports into the correct
target locations for each subproject.

In principle we should run lit's testsuite before testing LLVM using lit
so that any problems with lit get discovered before testing LLVM so we
can bail out early.  However this implementation (``check-all`` runs all

Note that the tests and the configured ``lit.site.cfg`` have to be
copied into the build directory to avoid polluting the source tree.

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!

Original commit message for r252949:

Provide a way to specify inliner's attribute compatibility and merging
rules using table-gen. NFC.

This commit adds new classes CompatRule and MergeRule to Attributes.td,
which are used to generate code to check attribute compatibility and
merge attributes of the caller and callee.

Dan Gohman db70d015ad Add an OperandNamespace field to Target.td's Operand.
For targets to add their own operand types as needed, as advertised in
Operand's comment, they need to be able to specify an alternate namespace
for OperandType names too. This matches the RegisterOperand class.

Akira Hatanaka a61deb249b Provide a way to specify inliner's attribute compatibility and merging.
This reapplies r252990 and r252949. I've added member function getKind
to the Attr classes which returns the enum or string of the attribute.

Chih-Hung Hsieh 7993e18e80 [X86] Part 2 to fix x86-64 fp128 calling convention.
Part 1 was submitted in http://reviews.llvm.org/D15134.
Changes in this part:
* X86RegisterInfo.td, X86RecognizableInstr.cpp: Add FR128 register class.
* X86CallingConv.td: Pass f128 values in XMM registers or on stack.
* X86InstrCompiler.td, X86InstrInfo.td, X86InstrSSE.td:
  Add instruction selection patterns for f128.
* X86ISelLowering.cpp:
  When target has MMX registers, configure MVT::f128 in FR128RegClass,
  with TypeSoftenFloat action, and custom actions for some opcodes.
  Add missed cases of MVT::f128 in places that handle f32, f64, or vector types.
  Add TODO comment to support f128 type in inline assembly code.
* SelectionDAGBuilder.cpp:
  Fix infinite loop when f128 type can have
  VT == TLI.getTypeToTransformTo(Ctx, VT).
* Add unit tests for x86-64 fp128 type.

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
