2a83943855 Try to fix ProgramTest on FreeBSD
This seemed like the cleanest way to find the test executable.  Also fix
the file mode.

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.

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.

To use this in conjunction with exuberant ctags to generate a single

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.

64110ffc9e Add SchedRW as an Instruction field.
Don't require instructions to inherit Sched<...>. Sometimes it is more
convenient to say:

  let SchedRW = ... in {
    ...
  }

Which is now possible.

1754aca83a MachineModel: Add a ProcResGroup class.
This allows abitrary groups of processor resources. Using something in
a subset automatically counts againts the superset. Currently, this
only works if the superset is also a ProcResGroup as opposed to a
SuperUnit.

This allows SandyBridge to be expressed naturally, which will be
checked in shortly.

def SBPort01 : ProcResGroup<[SBPort0, SBPort1]>;
def SBPort15 : ProcResGroup<[SBPort1, SBPort5]>;
def SBPort23  : ProcResGroup<[SBPort2, SBPort3]>;
def SBPort015 : ProcResGroup<[SBPort0, SBPort1, SBPort5]>;

c812110023 MIsched machine model: tablegen subtarget emitter improvement.
Fix the way resources are counted. I'm taking some time to cleanup the
way MachineScheduler handles in-order machine resources. Eventually
we'll need more PPC/Atom test cases in tree.

8eec41fc77 Unify clang/llvm attributes for asan/tsan/msan (LLVM part)
These are two related changes (one in llvm, one in clang).
LLVM: 
- rename address_safety => sanitize_address (the enum value is the same, so we preserve binary compatibility with old bitcode)
- rename thread_safety => sanitize_thread
- rename no_uninitialized_checks -> sanitize_memory

CLANG: 
- add __attribute__((no_sanitize_address)) as a synonym for __attribute__((no_address_safety_analysis))
- add __attribute__((no_sanitize_thread))
- add __attribute__((no_sanitize_memory))

for S in address thread memory
If -fsanitize=S is present and __attribute__((no_sanitize_S)) is not
set llvm attribute sanitize_S
