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.

763d8b2ef7 [TableGen] Fully resolve class-instance values before defs in multiclasses
By class-instance values I mean 'Class<Arg>' in 'Class<Arg>.Field' or in
'Other<Class<Arg>>' (syntactically s SimpleValue).  This is to differentiate
from unnamed/anonymous record definitions (syntactically an ObjectBody) which
are not affected by this change.

Consider the testcase:

    class Struct<int i> {
      int I = !shl(i, 1);
      int J = !shl(I, 1);
    }

    class Class<Struct s> {
        int Class_J = s.J;
    }

    multiclass MultiClass<int i> {
      def Def : Class<Struct<i>>;
    }

    defm Defm : MultiClass<2>;

Before this fix, DefmDef.Class_J yields !shl(I, 1) instead of 8.

This is the sequence of events.  We start with this:

    multiclass MultiClass<int i> {
      def Def : Class<Struct<i>>;
    }

During ParseDef the anonymous object for the class-instance value is created:

    multiclass Multiclass<int i> {
      def anonymous_0 : Struct<i>;

      def Def : Class<NAME#anonymous_0>;
    }

Then class Struct<i> is added to anonymous_0.  Also Class<NAME#anonymous_0> is
added to Def:

    multiclass Multiclass<int i> {
      def anonymous_0 {
        int I = !shl(i, 1);
        int J = !shl(I, 1);
      }

      def Def {
        int Class_J = NAME#anonymous_0.J;
      }
    }

So far so good but then we move on to instantiating this in the defm
by substituting the template arg 'i'.

This is how the anonymous prototype looks after fully instantiating.

    defm Defm = {
      def Defmanonymous_0 {
         int I = 4;
         int J = !shl(I, 1);
      }

Note that we only resolved the reference to the template arg.  The
non-template-arg reference in 'J' has not been resolved yet.

Then we go on to instantiating the Def prototype:

      def DefmDef {
         int Class_J = NAME#anonymous_0.J;
      }

Which is resolved to Defmanonymous_0.J and then to !shl(I, 1).

When we fully resolve each record in a defm, Defmanonymous_0.J does get set
to 8 but that's too late for its use.

The patch adds a new attribute to the Record class that indicates that this
def is actually a class-instance value that may be *used* by other defs in a
multiclass.  (This is unlike regular defs which don't reference each other and
thus can be resolved indepedently.)  They are then fully resolved before the
other defs while the multiclass is instantiated.

I added vg_leak to the new test.  I am not sure if this is necessary but I
don't think I have a way to test it.  I can also check in without the XFAIL
and let the bots test this part.

Also tested that X86.td.expanded and AAarch64.td.expanded were unchange before
and after this change.  (This issue triggering this problem is a WIP patch.)

d52b1d08df TableGen: delete no-op code
This does nothing but remove the Record from the map, and
then re-add it, without actually changing it in between.

The Record's Name used to be changed before re-adding it
when the code was first committed in r137232, but the
name-changing lines were removed in r142510, and since
then this code seems to do nothing.

This was also the only caller of removeClass or removeDef,
so now RecordKeeper owns its Records unconditionally,
and could be unique_ptr-ified.

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.

d80222a48b [tablegen] Add !listconcat operator with the similar semantics as !strconcat
Summary:
It concatenates two or more lists. In addition to the !strconcat semantics
the lists must have the same element type.

My overall aim is to make it easy to append to Instruction.Predicates
rather than override it. This can be done by concatenating lists passed as
arguments, or by concatenating lists passed in additional fields.

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

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.

f8ea5a5a27 Make sure TableGen exits with an error code after printing errors.
This makes it possible to report multiple errors in one invocation.
There are already calls to PrintError in CodeGenDAGPatterns.cpp which
previously would not cause TableGen to fail.

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.

to cleanup the PPC register definitions.

This allows us to produce more precise diagnostics about a certain

255f89faee Sort the #include lines for the include/... tree with the script.
AKA: Recompile *ALL* the source code!

This one went much better. No manual edits here. I spot-checked for
silliness and grep-checked for really broken edits and everything seemed
good. It all still compiles. Yell if you see something that looks goofy.

61131ab15f Remove exception handling usage from tblgen.
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.

PrintFatalError, which combines PrintError with exit(1).

This is a mechanical change of dynamic_cast<> to dyn_cast<>. A number of

to the semanticaly appropriate one in a future patch.

cdac1be34a Implement a correct copy constructor for Record. Now that we're using the ID number as a key in maps (for determinism), it is imperative that ID numbers be globally unique, even when we copy construct a Record.
This fixes some obscure failure cases involving registers defined inside multiclasses or foreach constructs that would not receive a unique ID, and would end up being omitted from the AsmMatcher tables.
