c1bb2d4325 Use pipefail when available.
This change makes test with RUN lines like
RUN: opt ... | FileCheck

fail if opt fails, even if it prints what FileCheck wants. Enabling this
found some interesting cases of broken tests that were not being noticed
because opt (or some other tool) was crashing late.

Pipefail is used when the shell supports it or when using the internal
python based tester.

563a9cf7ba Fix a bug in TableGen where the intrinsic function name recognizer could mis-identify names if one was a prefix substring of the other
For two intrinsics 'llvm.nvvm.texsurf.handle' and 'llvm.nvvm.texsurf.handle.internal',
TableGen was emitting matching code like:

  if (Name.startswith("llvm.nvvm.texsurf.handle")) ...
  if (Name.startswith("llvm.nvvm.texsurf.handle.internal")) ...

We can never match "llvm.nvvm.texsurf.handle.internal" here because it will
always be erroneously matched by the first condition.

The fix is to sort the intrinsic names and emit them in reverse order.

ba46086444 lit: Support cancellation on Windows
The current machinery using KeyboardInterrupt for canceling doesn't work
with multiple threads on Windows as it just cancels the currently run tests
but the runners continue.

We install a handler for Ctrl-C which stops the provider from providing any
more tests to the runners. Together with aborting all currently running
tests, this brings lit to a halt.

178504b07b Add new directive called CHECK-LABEL to FileCheck.
CHECK-LABEL is meant to be used in place on CHECK on lines containing identifiers or other unique labels (they need not actually be labels in the source or output language, though.) This is used to break up the input stream into separate blocks delineated by CHECK-LABEL lines, each of which is checked independently. This greatly improves the accuracy of errors and fix-it hints in many cases, and allows for FileCheck to recover from errors in one block by continuing to subsequent blocks.

Some tests will be converted to use this new directive in forthcoming patches.

ac226bbf45 Target/X86: Add explicit Win64 and System V/x86-64 calling conventions.
Summary:
This patch adds explicit calling convention types for the Win64 and
System V/x86-64 ABIs. This allows code to override the default, and use
the Win64 convention on a target that wants to use SysV (and
vice-versa). This is needed to implement the `ms_abi` and `sysv_abi` GNU
attributes.

b7110cf5b5 Improve the compression of the tablegen DiffLists by introducing a new sort
algorithm when assigning EnumValues to the synthesized registers.

The current algorithm, LessRecord, uses the StringRef compare_numeric
function.  This function compares strings, while handling embedded numbers.
For example, the R600 backend registers are sorted as follows:

  T1
  T1_W
  T1_X
  T1_XYZW
  T1_Y
  T1_Z
  T2
  T2_W
  T2_X
  T2_XYZW
  T2_Y
  T2_Z

In this example, the 'scaling factor' is dEnum/dN = 6 because T0, T1, T2
have an EnumValue offset of 6 from one another.  However, in other parts
of the register bank, the scaling factors are different:

dEnum/dN = 5:
  KC0_128_W
  KC0_128_X
  KC0_128_XYZW
  KC0_128_Y
  KC0_128_Z
  KC0_129_W
  KC0_129_X
  KC0_129_XYZW
  KC0_129_Y
  KC0_129_Z

The diff lists do not work correctly because different kinds of registers have
different 'scaling factors'.  This new algorithm, LessRecordRegister, tries to
enforce a scaling factor of 1.  For example, the registers are now sorted as
follows:

  T1
  T2
  T3
  ...
  T0_W
  T1_W
  T2_W
  ...
  T0_X
  T1_X
  T2_X
  ...
  KC0_128_W
  KC0_129_W
  KC0_130_W
  ...

For the Mips and R600 I see a 19% and 6% reduction in size, respectively.  I
did see a few small regressions, but the differences were on the order of a
few bytes (e.g., AArch64 was 16 bytes).  I suspect there will be even
greater wins for targets with larger register files.

Patch reviewed by Jakob.

898b9f020d TableGen: Generate a function for getting operand indices based on their defined names
This patch modifies TableGen to generate a function in
${TARGET}GenInstrInfo.inc called getNamedOperandIdx(), which can be used
to look up indices for operands based on their names.

In order to activate this feature for an instruction, you must set the
UseNamedOperandTable bit.

For example, if you have an instruction like:

def ADD : TargetInstr <(outs GPR:$dst), (ins GPR:$src0, GPR:$src1)>;

You can look up the operand indices using the new function, like this:

Target::getNamedOperandIdx(Target::ADD, Target::OpName::dst)  => 0
Target::getNamedOperandIdx(Target::ADD, Target::OpName::src0) => 1
Target::getNamedOperandIdx(Target::ADD, Target::OpName::src1) => 2

The operand names are case sensitive, so $dst and $DST are considered
different operands.

This change is useful for R600 which has instructions with a large number
of operands, many of which model single bit instruction configuration
values.  These configuration bits are common across most instructions,
but may have a different operand index depending on the instruction type.
It is useful to have a convenient way to look up the operand indices,
so these bits can be generically set on any instruction.

bed2308186 Add a way to define the bit range covered by a SubRegIndex.
NOTE: If this broke your out-of-tree backend, in *RegisterInfo.td, change
the instances of SubRegIndex that have a comps template arg to use the
ComposedSubRegIndex class instead.

In TableGen land, this adds Size and Offset attributes to SubRegIndex,
and the ComposedSubRegIndex class, for which the Size and Offset are
computed by TableGen. This also adds an accessor in MCRegisterInfo, and
Size/Offsets for the X86 and ARM subreg indices.

2275cfd75b Remove the MCRegAliasIterator tables and compute the aliases dynamically.
The size reduction in the RegDiffLists are rather dramatic.  Here are a few
size differences for MCTargetDesc.o files (before and after) in bytes:
R600 - 36160B - 11184B - 69% reduction
ARM - 28480B - 8368B - 71% reduction
Mips - 816B - 576B - 29% reduction

One side effect of dynamically computing the aliases is that the iterator does
not guarantee that the entries are ordered or that duplicates have been removed.
The documentation implies this is a safe assumption and I found no clients that
requires these attributes (i.e., strict ordering and uniqueness).

My local LNT tester results showed no execution-time failures or significant
compile-time regressions (i.e., beyond what I would consider noise) for -O0g,
-O2 and -O3 runs on x86_64 and i386 configurations.

d35da5055b Recognize ValueType operands in source patterns for fast-isel.
Currently the fast-isel table generator recognizes registers, register
classes, and immediates for source pattern operands.  ValueType
operands are not recognized.  This is not a problem for existing
targets with fast-isel support, but will not work for targets like
PowerPC and SPARC that use types in source patterns.

The proposed patch allows ValueType operands and treats them in the
same manner as register classes.  There is no convenient way to map
from a ValueType to a register class, but there's no need to do so.
The table generator already requires that all types in the source
pattern be identical, and we know the register class of the output
operand already.  So we just assign that register class to any
ValueType operands we encounter.

No functional effect on existing targets.  Testing deferred until the
PowerPC target implements fast-isel.

d999062f31 Handle tied sub-operands in AsmMatcherEmitter
The problem this patch addresses is the handling of register tie
constraints in AsmMatcherEmitter, where one operand is tied to a
sub-operand of another operand.  The typical scenario for this to
happen is the tie between the "write-back" register of a pre-inc
instruction, and the base register sub-operand of the memory address
operand of that instruction.

The current AsmMatcherEmitter code attempts to handle tied
operands by emitting the operand as usual first, and emitting
a CVT_Tied node when handling the second (tied) operand.  However,
this really only works correctly if the tied operand does not
have sub-operands (and isn't a sub-operand itself).  Under those
circumstances, a wrong MC operand list is generated.

In discussions with Jim Grosbach, it turned out that the MC operand
list really ought not to contain tied operands in the first place;
instead, it ought to consist of exactly those operands that are
named in the AsmString.  However, getting there requires significant
rework of (some) targets.

This patch fixes the immediate problem, and at the same time makes
one (small) step in the direction of the long-term solution, by
implementing two changes:

1. Restricts the AsmMatcherEmitter handling of tied operands to
   apply solely to simple operands (not complex operands or
   sub-operand of such).

This means that at least we don't get silently corrupt MC operand
lists as output.  However, if we do have tied sub-operands, they
would now no longer be handled at all, except for:

2. If we have an operand that does not occur in the AsmString,
   and also isn't handled as tied operand, simply emit a dummy
   MC operand (constant 0).

This works as long as target code never attempts to access
MC operands that do no not occur in the AsmString (and are
not tied simple operands), which happens to be the case for
all targets where this situation can occur (ARM and PowerPC).

[ Note that this change means that many of the ARM custom
  converters are now superfluous, since the implement the
  same "hack" now performed already by common code. ]

Longer term, we ought to fix targets to never access *any*
MC operand that does not occur in the AsmString (including
tied simple operands), and then finally completely remove
all such operands from the MC operand list.

Patch approved by Jim Grosbach.

19c3735262 Added the scripts git-svnup/git-svnrevert to utils/git-svn.
It makes more sense to have git-svnup here than catting said file in the
documentation (where we should rather point users to this directory).
I included git-svnrevert as an additional gift to the community. I will update
the documentation in a second commit later today.

git-svnrevert takes in a git hash for a commit, looks up the svn revision for
said commit and then creates the normal git revert commit message with the one
liner message, except instead of saying

  Revert "<<<INSERT ONELINER HERE>>>"

  This reverts commit <<<INSERT GITHASH HERE>>>

It says:

  Revert "<<<INSERT ONELINER HERE>>>"

  This reverts commit r<<<INSERT SVN REVISION HERE>>>

so git hashes will not escape into our svn logs (which just look unseemly).

0fc7137f2f Remove SMLoc paired with CHECK-NOT patterns. Not functionality change.
Pattern has source location by itself. After adding a trivial method to
retrieve it, it's unnecessary to pair a source location for CHECK-NOT patterns.
One thing revised after this is the diagnostic info is more accurate by
pointing to the start of the CHECK-NOT pattern instead of the end of the
CHECK-NOT pattern. E.g. diagnostic message previously looks like

    <stdin>:1:1: error: CHECK-NOT: string occurred!
    test
    ^
    test.txt:1:16: note: CHECK-NOT: pattern specified here
    CHECK-NOT: test
                   ^

is changed to

    <stdin>:1:1: error: CHECK-NOT: string occurred!
    test
    ^
    test.txt:1:12: note: CHECK-NOT: pattern specified here
    CHECK-NOT: test

f0a804df49 Allow direct value types in pattern definitions.
Just like register classes, value types can be used in two ways in
patterns:

  (sext_inreg i32:$src, i16)

In a named leaf node like i32:$src, the value type simply provides the
type of the node directly. This simplifies type inference a lot compared
to the current practice of specifiying types indirectly with register
classes.

As an unnamed leaf node, like i16 above, the value type represents
itself as an MVT::Other immediate.

7a42fb3b6e Make all unnamed RegisterClass TreePatternNodes typed MVT::i32.
A register class can appear as a leaf TreePatternNode with and without a
name:

  (COPY_TO_REGCLASS GPR:$src, F8RC)

In a named leaf node like GPR:$src, the register class provides type
information for the named variable represented by the node. The TypeSet
for such a node is the set of value types that the register class can
represent.

In an unnamed leaf node like F8RC above, the register class represents
itself as a kind of immediate. Such a node has the type MVT::i32,
we'll never create a virtual register representing it.

This change makes it possible to remove the special handling of
COPY_TO_REGCLASS in CodeGenDAGPatterns.cpp.

426db657da Add TableGen ctags(1) emitter and helper script.
To use this in conjunction with exuberant ctags to generate a single
combined tags file, run tblgen first and then
  $ ctags --append [...]

Since some identifiers have corresponding definitions in C++ code,
it can be useful (if using vim) to also use cscope, and
  :set cscopetagorder=1
so that
  :tag X
will preferentially select the tablegen symbol, while
  :cscope find g X
will always find the C++ symbol.

ec8d1a5b72 Extend TableGen instruction selection matcher to improve handling
of complex instruction operands (e.g. address modes).

Currently, if a Pat pattern creates an instruction that has a complex
operand (i.e. one that consists of multiple sub-operands at the MI
level), this operand must match a ComplexPattern DAG pattern with the
correct number of output operands.

This commit extends TableGen to alternatively allow match a complex
operands against multiple separate operands at the DAG level.

This allows using Pat patterns to match pre-increment nodes like
pre_store (which must have separate operands at the DAG level) onto
an instruction pattern that uses a multi-operand memory operand,
like the following example on PowerPC (will be committed as a
follow-on patch):

  def STWU  : DForm_1<37, (outs ptr_rc:$ea_res), (ins GPRC:$rS, memri:$dst),
                    "stwu $rS, $dst", LdStStoreUpd, []>,
                    RegConstraint<"$dst.reg = $ea_res">, NoEncode<"$ea_res">;

  def : Pat<(pre_store GPRC:$rS, ptr_rc:$ptrreg, iaddroff:$ptroff),
            (STWU GPRC:$rS, iaddroff:$ptroff, ptr_rc:$ptrreg)>;

Here, the pair of "ptroff" and "ptrreg" operands is matched onto the
complex operand "dst" of class "memri" in the "STWU" instruction.

Approved by Jakob Stoklund Olesen.

1ab961f6d3 Machine model. Allow mixed itinerary classes and SchedRW lists.
We always supported a mixture of the old itinerary model and new
per-operand model, but it required a level of indirection to map
itinerary classes to SchedRW lists. This was done for ARM A9.

Now we want to define x86 SchedRW lists, with the goal of removing its
itinerary classes, but still support the itineraries in the mean
time. When I original developed the model, Atom did not have
itineraries, so there was no reason to expect this requirement.

fa05def52c Allow targets to add custom asm operand matching logic.
For example, ARM has several instructions with a literal '#0' immediate in the syntax
that's not represented as an actual operand. The asm matcher is expected a token
operand, but the parser will have created an immediate operand. This is currently
handled by dedicated per-instruction C++ munging of the ParsedAsmOperand list, but
will be better handled by this hook.

72062f5744 Add AArch64 as an experimental target.
This patch adds support for AArch64 (ARM's 64-bit architecture) to
LLVM in the "experimental" category. Currently, it won't be built
unless requested explicitly.

This initial commit should have support for:
    + Assembly of all scalar (i.e. non-NEON, non-Crypto) instructions
      (except the late addition CRC instructions).
    + CodeGen features required for C++03 and C99.
    + Compilation for the "small" memory model: code+static data <
      4GB.
    + Absolute and position-independent code.
    + GNU-style (i.e. "__thread") TLS.
    + Debugging information.

The principal omission, currently, is performance tuning.

This patch excludes the NEON support also reviewed due to an outbreak of
batshit insanity in our legal department. That will be committed soon bringing
the changes to precisely what has been approved.

Further reviews would be gratefully received.

1917aaff29 [CMake][Lit][unittests] Deprecate CMAKE_BUILD_TYPE in each build directory for unittests.
For example,
cur) unittests/ADT/Release/ADTTests
new) unittests/ADT/ADTTests

RUNTIME_BUILD_MODE can be substituted to CMAKE_CFG_INTDIR.

With Make and Ninja, the tree is not built with multiple configurations.
Then, including the build type in target directory doesn't make sense.
See also "How can I build multiple modes without switching?"
http://www.cmake.org/Wiki/CMake_FAQ
CMAKE_CFG_INTDIR is set to "."

With multiple-configuration-aware build system, like Visual Studio, each unittest is built on appropriate directory, for example,
unittests/ADT/Release/ADTTests.exe
CMAKE_CFG_INTDIR is set to build system's variable, like "$(Configuration)" or "$(OutDir)".

Thus, "--param build_config" is also deprecated.

114baee1fa Add the IR attribute 'sspstrong'.
SSPStrong applies a heuristic to insert stack protectors in these situations:

* A Protector is required for functions which contain an array, regardless of
  type or length.

* A Protector is required for functions which contain a structure/union which
  contains an array, regardless of type or length.  Note, there is no limit to
  the depth of nesting.

* A protector is required when the address of a local variable (i.e., stack
  based variable) is exposed. (E.g., such as through a local whose address is
  taken as part of the RHS of an assignment or a local whose address is taken as
  part of a function argument.)

This patch implements the SSPString attribute to be equivalent to
SSPRequired. This will change in a subsequent patch.

This change is basically just copying changes that we've used for Apple's
clang builds to the script used for building llvmCore. Besides cleaning it
up to use xcrun to locate the proper versions of tools, especially for cross
compiling, it fixes the build to work with newer versions of clang that
honor SDKROOT settings in the environment.

88abcde3b4 Make TableGen mangle operand method names before putting in enum.
The purpose of this patch is to allow PredicateMethods to be set to something
like "isUImm<8>", calling a C++ template method to reduce code duplication. For
this to work, the PredicateMethod must be mangled into a valid C++ identifier
for insertion into an enum.

7bf2e1b9ef Check whether MCInst operand isImm before calling getImm.
When processing possible aliases, TableGen assumes that if an operand *can* be
an immediate, then it always *will* be. This is incorrect for the AArch64
backend. This patch inserts a check in the generated code to make sure isImm is
true first.

c2c50cdcdc Rename VMCore directory to IR.
Aside from moving the actual files, this patch only updates the build
system and the source file comments under lib/... that are relevant.

I'll be updating other docs and other files in smaller subsequnet
commits.

While I've tried to test this, but it is entirely possible that there
will still be some build system fallout.

Also, note that I've not changed the library name itself: libLLVMCore.a
is still the library name. I'd be interested in others' opinions about
whether we should rename this as well (I think we should, just not sure
what it might break)

57f7dafcb7 Modify the LLVM checkout of googletest:
1) don't delete gtest-all.cc (which is used to gather all gtest source
   files in a single file) 
2) make including LLVMSupport headers optional (on by default).
   Sanitizer tools may want to use their own versions of googletest
   compiled with specific flags, instead of the common googletest
   library used for all other LLVM/Clang unittests.

as "a && (b || true)" in Tcl mode, and as "(a && b) || true" in sh mode.
Everyone seems to (quite reasonably) write tests assuming the Tcl behavior,
so use that in sh mode too.

eca1fcf3d2 RegisterPressure API. Add support for physical register units.
At build-time register pressure was always computed in terms of
register units. But the compile-time API was expressed in terms of
register classes because it was intended for virtual registers (and
physical register units weren't yet used anywhere in codegen).

Now that the codegen uses physreg units consistently, prepare for
tracking register pressure also in terms of live units, not live
registers.

1) Teach it to handle files with #include on the first line -- these do
   actually exist in LLVM.
2) Support llvm-c and clang-c include projects.
3) Nuke some stail imports.
4) Switch to using os.path to split the file extension off.
5) Remove debugging leftovers.
6) Add docstring (a really puny one) for the sort function.

I'm continuing te avoid stripping the whitespace on the RHS to preserve
whatever newline characters happen to be in the original file.

I am a terrible Python programmer. Patches more the welcome. Please tell
me how this should look if it should look differently. It's just a tiny
little script so it didn't make sense to go through pre-commit review,
especially as someone who actually knows python may want to just rip it
apart and do it The Right Way.

I will be preparing a commit shortly that uses this script to
canonicalize *all* of the #include lines in LLVM. Really, all of them.

4db6511779 Fix a bug in FileCheck that wouldn't let define variables as follows:
; CHECK: [[VAR:[a-z]]]

The problem was that to find the end of the regex var definition, it was
simplistically looking for the next ]] and finding the incorrect one. A
better approach is to count nesting of brackets (taking escaping into
account). This way the brackets that are part of the regex can be discovered
and skipped properly, and the ]] ending is detected in the right place.

When code deletes the context, the AttributeImpls that the AttrListPtr points to
are now invalid. Therefore, instead of keeping a separate managed static for the
AttrListPtrs that's reference counted, move it into the LLVMContext and delete
it when deleting the AttributeImpls.

Most places can use PrintFatalError as the unwinding mechanism was not
used for anything other than printing the error. The single exception
was CodeGenDAGPatterns.cpp, where intermediate errors during type
resolution were ignored to simplify incremental platform development.
This use is replaced by an error flag in TreePattern and bailout earlier
in various places if it is set.
