This method is used to find complete definitions of a type when one
parses a compile unit with only forward declaration available.
Since it is only accessed from DWARFASTParserClang, it was not
possible/easy to trigger this codepath from lldb-test. Therefore, I
adapt add a debug-names variant to an existing dotest test to cover this
scenario.

Apparently some compilers generate incomplete debug information which
caused the updated test to fail. Therefore I've extracted the new check

Before Pavel's change in r334181, we were printing too many global

In r331719, I changed Module::FindTypes not to limit the amount
of types returned by the Symbol provider, because we want all
possible matches to be able to filter them. In one code path,
the filtering was applied to the TypeList without changing the
number of types that gets returned. This is turn could cause
consumers to access beyond the end of the TypeList.
This patch fixes this case and also adds an assertion to
TypeList::GetTypeAtIndex to catch those obvious programming
mistakes.
Triggering the condition in which we performed the incorrect
access was not easy. It happened a lot in mixed Swift/ObjectiveC
code, but I was able to trigger it in pure Objective C++ although
in a contrieved way.

Re-enable TestUnicodeSymbols now that we use the in-tree dsymutil. This
was disabled because the hashing of unicode symbols was out of sync
between llvm (dsymutil) and lldb.
llvm-svn: 331764
Summary:
... and fix one bug found this way. Currently, the test works not because
types are looked up correctly, but because by injecting local variables
we also materialize the types for Clang. If we disable the local variable
injection, then one check fails.
The reason of the failure is that FindTypes is run with max_matches==1
and this value is passed down to the symbol lookup functions. When the
search is performed only on the basename (like it's the case for an
entity defined in the root namespace), then the search will stop after
having found one match on the basename. But that match might be in a
namespace, we were really just looking up the basename in the accelerator
tables.
The solution is to not pass max_matches down, but to search without a
limit and let RemoveMismatchedTypes do its job afterwards. Note the
patch includes 2 hunks with the same change, but only the latter is
tested. I couldn't find a way to create a testcase for the other
branch of the if ('image lookup -t' allows me to get there, but it
only ever returns one type anyway).

Displaying of global pointer variables is not working on arm64 linux
(pr37301).
I've moved this part into a separate test, so it can be xfailed
separately. I then move the "show-variables-with-process-available"
check before the "show-all-variables" command to presrve the intent of
checking that global variable caching works correctly. (I've verified
that the new arrangement still fails when I revert the fix from
r331230.)
llvm-svn: 331250
This fixes a bug where
(lldb) target var g_ptr
would populate the global variables list with exactly one entry
because SymbolFileDWARF::ParseVariables() was invoked with a list of
DIEs pre-filtered by name, such that a subsequent call to
(lldb) fr var --show-globals
would only list that one variable, because CompileUnit::m_variables
was already initialized, fooling CompileUnit::GetVariableList().
CompileUnit::GetVariableList() grabs the *complete* list of variables
via (SymbolFileDWARF, ...)::ParseVariablesForContext and that still
calls CompileUnit::SetVariableList(variables) which acts as the
caching mechanism.

Summary:
We would fail to resolve (and thus display the value of) any

- use more goodies from Makefile.rules to correctly build a 32-bit

- avoid hardcoding typeof(nil) in the test.

Instead of applying the sledgehammer of refusing to insert any
C++ symbol in the ASTContext, try to validate the decl if what
we have is an operator. There was other code in lldb which was
responsible for this, just not really exposed (or used) in this
codepath. Also, add a better/more comprehensive test.

Summary:
When in a gmodules-like debugging scenario, you can have a parent decl context
that gets imported from an external AST. When this happens, we must be careful
to complete this type before adding children to it, otherwise it sometimes
results in a crash.

Until we have a better story for putting commands and check lines
in the same file (they're currently ignored), it seems that inline
tests are actually more concise and easier to understand.
Too bad we have still some python boilerplate, but that's not
really substantial so we can live with it.
Thanks to Fred for pointing out and Jim for explaining me how
to use the inline test format.

It turns out that setting the clang module cache after LLDB has a
Target can be too late. In particular, the Swift language plugin needs
to know the setting without having access to a Target. This patch
moves the setting into the *LLDB* module cache, where it is a global
setting that is available before any Target is created and more
importantly, is shared between all Targets.

gcc will say that the type of "this" is "T * const", clang "T *".
Compare the unqualified type names to erase the difference between the
two, as the constness is not a part of this test.
FWIW, I think that the gcc behavior makes more sense here.

There's a bug in FindTypes, it ignores the exact flag if you pass a name that doesn't begin with
:: and pass eTypeClassAny for the type.
In this case we always know that the name we get from the vtable name is absolute so we can
work around the bug by prepending the "::". This doesn't fix the FindTypes bug.

Without this fix, the test ERRORs because the link of the inferior fails. This
patch adds the LLDB_TEST_API macro where needed and uses the new -2 magic
value for num_expected_locations to account for lazy-loading of module symbols
on Windows.
With this fix, the test itself still fails: conflicting_symbol isn't in the
debug info nor the export table, and Windows binaries don't have an equivalent
of the ELF .symtab. We need to understand why the test works to keep the
symbol out of the debug info. In the mean time, having the test fail at this
point is a better indication of the remaining problem than a build error.

Summary:
The llvm function is equivalent to this one. Where possible I tried to
replace const char* with llvm::StringRef to avoid extra strlen
computations. In most places, I was able to track the c string back to
the ConstString it was created from.
I also create a test that verifies we are able to lookup names with
unicode characters, as a bug in the llvm compiler (it accidentally used
a different hash function) meant this was not working until recently.
This also removes the unused ExportTable class.
