Input constraints like "0" and "[foo]" should be treated the same when
it comes to their corresponding output constraint.
This fixes PR21850.

-Wself-move is similiar to -Wself-assign. This warning is triggered when
a value is attempted to be moved to itself. See r221008 for a bug that
would have been caught with this warning.

Their linkage can change if they are later explicitly instantiated. We would
previously emit such functions eagerly (as opposed to lazily on first use) if
they have a 'dllexport' or 'used' attribute, and fail an assert when hitting the
explicit instantiation.
This is achieved by replacing the old CodeGenModule::MayDeferGeneration() method
with two new ones: MustBeEmitted() and MayBeEmittedEagerly().

This reverts commit r225000, r225021, r225083, r225086, r225090.
The root change (r225000) still has several issues where it's caused
calls to be emitted without debug locations. This causes assertion
failures if/when those calls are inlined.
I'll work up some test cases and fixes before recommitting this.

It seemed odd to have to make DefaultImageName be a mutable member of Driver.
We don't need to the full result of computeTargetTriple() to determine the
image name; just base it on DefaultTargetTriple.

We have a diagnostic describing that constexpr changed in C++14 when
compiling in C++11 mode. While doing this, it examines the previous
declaration and assumes that it is a function. However it is possible,
in the context of error recovery, for this to not be the case.

Parser::ParseNamespace can get a little confused when it found itself
inside a compound statement inside of a non-static data member
initializer.
Try to determine that the statement expression's scope makes sense
before trying to parse it's contents.

We assumed that class-scope specializations would result in a
CXXMethodDecl for that class. However, globally qualified functions
will result in normal FunctionDecls.

Sema::CheckParmsForFunctionDef can't cope with a null TypeSourceInfo.
Don't let the AST contain the malformed lambda.
This fixes PR22122.

Allow blessed access to the symbol rewriter from the driver. Although the
symbol rewriter could be invoked through tools like opt and llc, it would not
accessible from the frontend. This allows us to read the rewrite map files in
the frontend rather than the backend and enable symbol rewriting for actually
performing the symbol interpositioning.

We were previously emitting counter increments even if we didn't have
an insertion point, which would result in a CallInst with no
parent. This leads to a crash, as in pr22166, if we try to do
GlobalDCE.
llvm-svn: 225495
We forgot to mark designated initializer expression that contain type
dependent array designators as type dependent. This would lead to
crashes when we try to determine which array element we were trying to
initialize.
This fixes PR22056.

we're instantiating, if there's a ParmVarDecl within a FunctionDecl context
that is not a parameter of that function. Add some asserts to catch this kind
of issue more generally, and fix another bug exposed by those asserts where we
were missing a local instantiation scope around substitution of
explicitly-specified template arguments.

better than the 'template-parameter-x-y' name that we'd get in AST printing,
and is worse in several ways (it's harder to distinguish it from a
user-supplied name, it's wrong after substituting some number of outer
levels, it wastes time and space constructing an IdentifierInfo, ...).

If there are some non-ascii character in the input source code, the
column index might be smallar than the byte index. This will result
in two possible assertion failures. This CL fixes the computation of
the column index and byte index.
1. The assertion in startOfNextColumn() and startOfPreviousColumn()
should not be raised when the byte index is greater than the column
index since the non-ascii characters may use more than one bytes to
store a character in a column.
2. The length of the caret line should be equal to the number of columns
of source line, instead of the length of the source line. Otherwise,
the assertion in selectInterestingSourceRegion will be raised because
the removed columns plus the kept columns are not greater than the max
column, which means that we should not remove any column at all.

transform.
Also diagnose typos in the initializer of an invalid C++ declaration.
Both issues were hit using the same line of test code, depending on
whether the code was treated as C or C++.
Fixes PR22092.

Shorter and doesn't need -O2 -- but still suboptimal as it's still doing
-emit-obj. dblaikie says he'll improve this when he'll reland his change
with a fix.

PR22096 has several test cases that assert that look fairly different. I'm
adding one of those as an automated test, but when relanding the other cases
should probably be checked as well.
llvm-svn: 225361
Add additional constraint checking for target specific behaviour for inline
assembly constraints. We would previously silently let all arguments through
for these constraints. In cases where the constraints were violated, we could
end up failing to select instructions and triggering assertions or worse,
silently ignoring instructions.

Summary:
Allow -fsanitize-coverage=N with ubsan, clang part.
This simply allows the flag combination.
The LLVM will work out of the box, the compile-rt part
will follow as a separate patch.

For some regression tests the path to the right toolchain is specified using the -sysroot switch. However, if clang was configured with a custom gcc toolchain (either by using GCC_INSTALL_PREFIX in cmake or the equivalent configure command), the path to the custom gcc toolchain path takes precedence to the one specified by sysroot. This causes several regression tests to fail as they will be using an unexpected path. This patch fixes this issue by adding --gcc-toolchain='' to all tests that rely on that. The empty string causes the driver to pick the path from sysroot instead.

r185773 added an assert that checked that a CXXUnresolvedConstructExpr either
has a valid rparen, or exactly one argument. This doesn't have to be true for
invalid inputs. Convert the assert to an if, and add a test for this case.
