Also, make it slightly clearer what's being tested by only differentiating integer
literals based on their suffix, rather than using a very large constant.

Change the lit RUN commands for 3 tests to use the following pattern
"FileCheck -input-file ..." instead of "cat ... | FileCheck ..." as
suggested by Justin Bogner.

This patch adds the tests for the coverage mapping generation.
Most of the tests check the mapping regions produced by
the generator, and one checks the llvm IR.

Changes diagnostic options, language standard options, diagnostic identifiers, diagnostic wording to use c++14 instead of c++1y. It also modifies related test cases to use the updated diagnostic wording.

MSVC "14" CTP 3 has fixed it's mangling for alias templates when used as
template-template arguments; update clang to be compatible with this
mangling.

1. Always put static sanitizer runtimes to the front of the linker
invocation line. This was already done for all sanitizers except UBSan:
in case user provides static libstdc++ we need to make sure that new/delete
operator definitions are picked from sanitizer runtimes instead of libstdc++.
We have to put UBSan runtime first for similar reasons: it depends on some
libstdc++ parts (e.g. __dynamic_cast function), and has to go first in
link line to ensure these functions will be picked up from libstdc++.
2. Put sanitizer libraries system dependencies (-ldl, -lpthread etc.) right
after sanitizer runtimes. This will ensure these libraries participate in
the link even if user provided -Wl,-as-needed flag. This should fix PR15823.
3. In case we link in several sanitizer runtimes (e.g. "ubsan", "ubsan_cxx"
and "san"), add system dependencies (-ldl, -lpthread, ...) only once.

Predefined decls like 'Protocol' in objc are not loaded from AST files,
so we cannot rely on loading the canonical decl to complete the redecl
chain for redeclarations of these decls. The broken redecl chain was
non-circular, so looping over redecls() would hang.

Summary:
Adding remaining 2 cases handling:
* from x32 to 32 via -m32
* from x32 to 64 via -m64

Name might be empty again after we removed the '%' prefix
and Name[0] would assert.
Found on code like
register int foo asm("%" MACRO);
where MACRO was supposed to be defined in a header file that was not found.

tables that correspond to ContinuousRangeMaps, since the keys to those
maps need to be unique, or we may map to the wrong offset.
This fixes a crash + malformed AST file seen when loading some modules
that import Cocoa on Darwin, which is a module with no contents except
imports of other modules. Unfortunately I have not been able to find a
reduced test case that reproduces this problem.
Also add an assert that we aren't mapping one key to multiple values
in CRM. We ought to be able to say there are no duplicate keys at all,
but there are a bunch of 0 -> 0 mappings that are showing up, probably
coming from the source location table.

This reverts commit r215785 / 170ebf4f19459ae51a9561d0e65c87ee4c9b2c97.
LLD has some StringSavers that need to be updated. One of which takes a
lock and I need to investigate that more closely.

This fixes PR20671, see the bug for details. In short, ActOnTranslationUnit()
calls DefineUsedVTables() and only then PerformPendingInstantiations(). But
PerformPendingInstantiations() is what does delayed template parsing, so
vtables only references from late-parsed templates weren't marked used.
As a fix, move the SavePendingInstantiationsAndVTableUsesRAII in
PerformPendingInstantiations() up above the delayed template parsing code.
That way, vtables referenced from templates end up in the RAII object, and the
call to DefineUsedVTables() in PerformPendingInstantiations() marks them used.
llvm-svn: 215786
There is more cleanup to be done here. Once
llvm::sys::Process::GetArgumentVector is switched over to StringSaver,
we can simplify this code a fair amount.
