Summary:
As part of moving the argument lowering handling for bfloat arguments and
returns to the backend, this patch removes the code that was responsible for
handling the coercion of those arguments in Clang's Codegen.

Summary:
Compiler may erroneously treat current context in OpenMP pragmas as the
context where new type declaration/definition is allowed. But the
declartation/definition of the new types in OpenMP pragmas should not be
allowed.

Previously the script only handled C input, this change extends the JSON
parsing to to also include C++ function types such as methods, constructors
and destructors.

Function declarations can in fact have an 'inner' node that lists the
ParmVarDecls. It seems like either the JSON output has changed or that I
tested the original JSON parsing change with test files that only have
function definitions without arguments.

This patch adds some missing information to the LF_BUILDINFO which allows for rebuilding an .OBJ without any external dependency but the .OBJ itself (other than the compiler executable).
Some tools need this information to reproduce a build without any knowledge of the build system. The LF_BUILDINFO therefore stores a full path to the compiler, the PWD (which is the CWD at program startup), a relative or absolute path to the TU, and the full CC1 command line. The command line needs to be freestanding (not depend on any environment variable). In the same way, MSVC doesn't store the provided command-line, but an expanded version (somehow their equivalent of CC1) which is also freestanding.
For more information see PR36198 and D43002.

Currently rocm detector expects device library bitcodes named as *.bc
instead of *.amdgcn.bc. However in rocm3.5 the device library bitcodes
are named as *.amdgcn.bc, which causes rocm3.5 not detected.

An AST serialization dump test is a test which compares the output of -ast-dump

The body of LambdaExpr is currently not properly serialized. Instead
LambdaExpr::getBody checks if the body has been already deserialized and if
not mutates LambdaExpr. This can be observed with an AST dump test, where
the body of the LambdaExpr will be null.
The mutation in LambdaExpr::getBody was left because of another bug: it is not
true that the body of a LambdaExpr is always a CompoundStmt; it can also be
a CoroutineBodyStmt wrapping a CompoundStmt. This is fixed by returning a
Stmt * from getBody and introducing a convenience function getCompoundStmtBody
which always returns a CompoundStmt *. This function can be used by callers who
do not care about the coroutine node.
Happily all but one user of getBody treat it as a Stmt * and so this change
is non-intrusive.

The Android NDK's clang driver is used with an Android -target setting,

Remove Hurd::computeSysRoot as it is equivalent to the new
ToolChain::computeSysRoot method.

outer levels as retained rather than omitting their arguments.
This better reflects what's going on (we're performing a substitution
while still inside a template). In theory this is also more correct, but
I've not found a testcase where it matters in practice (largely because
we don't allow alias templates to be declared inside a function).
templated class.
When a defaulted operator<=> results in the injection of a defaulted
operator==, that operator== can be named by unqualified name within the
same class, even if the class is templated. To make this work, perform
the transform from defaulted operator<=> to defaulted operator== in the
template definition context instead of the template instantiation
context.
This results in our substituting into a declaration from a context where
we don't have a full list of template arguments (or indeed any), for
which we are now more careful to not spuriously instantiate declarations
that are not dependent on the arguments we're substituting.
Summary:
Add a flag to omit the xray_fn_idx to cut size overhead and relocations
roughly in half at the cost of reduced performance for single function
patching. Minor additions to compiler-rt support per-function patching
without the index.

Summary:
The OpenMP loops are normalized and transformed into the loops from 0 to
max number of iterations. In some cases, original scheme may lead to
overflow during calculation of number of iterations. If it is unknown,
if we can end up with overflow or not (the bounds are not constant and
we cannot define if there is an overflow), cast original type to the
unsigned.

I originally reverted the patch because it was causing performance
issues, but now I think it's just enabling simplify-cfg to do
something that I don't want instead :)
Sorry for the noise.
This reverts commit 3e39760f8e.
We weren't re-entering template scopes in the right order, causing this
