Problem:
On SystemZ we need to open text files in text mode. On Windows, files opened in text mode adds a CRLF '\r\n' which may not be desirable.
Solution:
This patch adds two new flags
- OF_CRLF which indicates that CRLF translation is used.
- OF_TextWithCRLF = OF_Text | OF_CRLF indicates that the file is text and uses CRLF translation.
Developers should now use either the OF_Text or OF_TextWithCRLF for text files and OF_None for binary files. If the developer doesn't want carriage returns on Windows, they should use OF_Text, if they do want carriage returns on Windows, they should use OF_TextWithCRLF.
So this is the behaviour per platform with my patch:
z/OS:
OF_None: open in binary mode
OF_Text : open in text mode
OF_TextWithCRLF: open in text mode
Windows:
OF_None: open file with no carriage return
OF_Text: open file with no carriage return
OF_TextWithCRLF: open file with carriage return
The Major change is in llvm/lib/Support/Windows/Path.inc to only set text mode if the OF_CRLF is set.
```
if (Flags & OF_CRLF)
CrtOpenFlags |= _O_TEXT;
```
These following files are the ones that still use OF_Text which I left unchanged. I modified all these except raw_ostream.cpp in recent patches so I know these were previously in Binary mode on Windows.
./llvm/lib/Support/raw_ostream.cpp
./llvm/lib/TableGen/Main.cpp

Remove the find_package(Python3 ...) call from Tooling/CMakeLists.txt as
it would override the python 3 version determined in llvm/CMakeLists.txt.
This call did not respect the LLVM_MINIMUM_PYTHON_VERSION.
This fixes the check-all target when building LLVM on a system where the
default python version is not the minimum required version for running tests.

In D84673, we started using `DiagnosticsEngine` during command-line parsing in more contexts.
When using `ToolInvocation`, a custom `DiagnosticsConsumer` can be specified and it might expect `SourceManager` to be present on the emitted diagnostics.
This patch ensures the `SourceManager` is set up in such scenarios.

The reason for the NewPM redesign is described in the commit
cba3e783389a: [NewPM] Disable PreservedCFGChecker ...
The checker introduces an internal custom CFG analysis that tracks
current up-to date CFG snapshot. The analysis is invalidated along
any other CFG related analysis (the key is CFGAnalyses). If the CFG
analysis is not invalidated at a functional pass exit then the checker
asserts that the CFG snapshot taken from this analysis is equals to
a snapshot of the current CFG.
Along the way:
- the function CFG::printDiff() is simplified by removing function
name calculation. The name is printed by the caller;
- fixed CFG invalidated condition (see CFG::invalidate());
- StandardInstrumentations::registerCallbacks() gets additional
optional parameter of type FunctionAnalysisManager*, which is
needed by the checker to get the custom CFG analysis;
- several PM related tests updated to explicitly set
-verify-cfg-preserved=1 as they need.
This patch is safe to land as the CFGChecker is left switched off
(the options -verify-cfg-preserved is false by default). It will be
switched on by a separate patch to minimize possible reverts.

This changes our approach to processing statement attributes to be more
similar to how we process declaration attributes. Namely,
ActOnAttributedStmt() now calls ProcessStmtAttributes() instead of
vice-versa, and there is now an interface split between building an
attributed statement where you already have a list of semantic
attributes and building an attributed statement with attributes from
the parser.
This should make it easier to support statement attributes that are
dependent on a template. In that case, you would add a
TransformFooAttr() function in TreeTransform.h to perform the semantic
checking (morally similar to how Sema::InstantiateAttrs() already works
for declaration attributes) when transforming the semantic attribute at
instantiation time.
Clang test CodeGenOpenCL/fpmath.cl uses a variable defined in an earlier
CHECK-NOT directive. However, by definition the pattern in that
directive is not supposed to occur so no variable will be defined. This
commit solves the issue by using a regex match with the same regex as in
the definition. It also changes the definition into a regex match since
no variable is going to be defined.

This patch adds two debug functions to ExprInspectionChecker to dump out
the dynamic extent and element count of symbolic values:
dumpExtent(), dumpElementCount().
Clang used to emit a bad -Wbridge-cast diagnostic on the cast in the attached
test. This was because, after 09abecef7, struct __CFString was not added to
lookup, so the objc_bridge attribute wasn't getting duplicated onto the most
recent declaration, causing us to fail to find it in getObjCBridgeAttr. This
patch fixes this by instead walking through the redeclarations to find an
appropriate bridge attribute. rdar://72823399

Clang test CodeGen/debug-info-extern-call.c tries to check for the
absence of a sequence of instructions with several CHECK-NOT with one of
those directives using a variable defined in another. However CHECK-NOT
are checked independently so that is using a variable defined in a
pattern that should not occur in the input.
This commit removes the CHECK-NOT for the retained line attribute
definition since the CHECK-NOT on the compile unit will already check
that there is no retained lines.

as requested in https://bugs.llvm.org/show_bug.cgi?id=49553, submitting the proposed changes to just ignore the -flto= options which are recognized by GCC ("auto" and "jobserver").
GCC supports -flto=<auto|jobserver|<N> to select the parallelity for LTO builds. LLVM also has -flto-jobs=<N>, which only seems to have a meaning when used with -flto=thin?
The attached patch just ignores the values "auto" and "jobserver". that doesn't change anything in functionality. Another option would be to map these values to either "thin" or "full", maybe in presence of the -ffat-lto-objects option?
-flto=<n> could also be translated to -flto-jobs=<N>.

Take gcc-8 on Debian i386 as an example. The target-specific libstdc++ search
path (`GPLUSPLUS_TOOL_INCLUDE_DIR`) uses the multiarch name `i386-linux-gnu`,
instead of the triple of the GCC installation `i686-linux-gnu` (the directory
under `usr/lib/gcc/`):
```
/usr/include/c++/8
/usr/include/i386-linux-gnu/c++/8
/usr/include/c++/8/backward
```
Clang currently detects `/usr/lib/gcc/i686-linux-gnu/8/../../../include/i686-linux-gnu/c++/8`.
This patch changes the second i686-linux-gnu to i386-linux-gnu so that
`/usr/include/i386-linux-gnu/c++/8` can be found.

These all pass 1 type to getIntrinsic. So rather than assigning
IntrinsicTypes for each builtin which invokes the SmallVector
constructor, just select the intrinsic ID with a switch and
share a single assignment of IntrinsicTypes.
Currently, when one or more attributes are mutually exclusive, the
developer adding the attribute has to manually emit diagnostics. In
practice, this is highly error prone, especially for declaration
attributes, because such checking is not trivial. Redeclarations
require you to write a "merge" function to diagnose mutually exclusive
attributes and most attributes get this wrong.
This patch introduces a table-generated way to specify that a group of
two or more attributes are mutually exclusive:
def : MutualExclusions<[Attr1, Attr2, Attr3]>;
This works for both statement and declaration attributes (but not type
attributes) and the checking is done either from the common attribute
diagnostic checking code or from within mergeDeclAttribute() when
merging redeclarations.
