George Karpenkov f37c07c313 [analyzer] [tests] [NFC] Remove dead code from CmpRuns
Indeed, "CHANGE" is not a thing yet, and we should probably not carry
around dead code which does not do anything apart from confusing the
reader.

Richard Smith 33bddbd64b Make attribute instantiation instantiate all attributes, not just the first of
each kind.

Attribute instantiation would previously default to instantiating each kind of
attribute only once. This was overridden by a flag whose intended purpose was
to permit attributes from a prior declaration to be inherited onto a new
declaration even if that new declaration had its own copy of the attribute.
This is the wrong behavior: when instantiating attributes from a template, we
should always instantiate all the attributes that were written on that
template.

This patch renames the flag in the Attr class (and TableGen sources) to more
clearly identify what it's actually for, and removes the usage of the flag from
template instantiation. I also removed the flag from AlignedAttr, which was
only added to work around the incorrect suppression of duplicate attribute
instantiation.

Aaron Ballman 10007815ac Introduce some infrastructure for adding C attributes with [[]] syntax.
This patch adds support to the attribute tablegen for specifying a [[]] attribute is allowed in C mode. This patch also adds the annotate attribute to the list of double square bracket attributes we support in C mode.

Eventually, I anticipate that this logic will be reversed (you have to opt out of allowing an attribute in C rather than opting in), but I want to see how the design plays out as more attributes are considered.

Erich Keane 7544967108 Add support for ObjectFormat to TargetSpecificAttr
Looking through the code, I saw a FIXME on IFunc to switch it
to a target specific attribute. In looking through it, i saw that
the no-longer-appropriately-named TargetArch didn't support ObjectFormat
checking.

This patch changes the name of TargetArch to TargetSpecific
(since it checks much more than just Arch), makes "Arch" optional, adds
support for ObjectFormat, better documents the TargetSpecific type, and
changes IFunc over to a TargetSpecificAttr.

Aaron Ballman adf66b6174 Determine the attribute subject for diagnostics based on declarative information in DeclNodes.td. This greatly reduces the number of enumerated values used for more complex diagnostics; these are now only required when the "attribute only applies to" diagnostic needs to be generated manually as part of semantic processing.
This also clarifies some terminology used by the diagnostic (methods -> Objective-C methods, fields -> non-static data members, etc).

Many of the tests needed to be updated in multiple places for the diagnostic wording tweaks. The first instance of the diagnostic for that attribute is fully specified and subsequent instances cut off the complete list (to make it easier if additional subjects are added in the future for the attribute).

George Karpenkov 3c128cb1e6 [analyzer] [tests] Remove empty folders in reference results, do not store diffs.txt
Storing diffs.txt is now redundant, as we simply dump the CmpRuns output
to stdout (it is saved in CI and tends to be small).
Not generating those files enables us to remove empty folders, which
confuse git, as it would not add them with reference results.

Aaron Ballman ffc4336665 Add a new attribute definition spelling, Clang<"attr">, that expands to two attribute spellings: GNU<"attr"> and CXX11<"clang", "attr">. This is similar to how the GCC spelling works and is intended to be used for attributes introduced for Clang.
Changes all existing attributes that currently use GNU<"attr"> and CXX11<"clang", "attr> spellings to instead use the Clang<"attr"> spelling.

No additional tests are necessary because the existing tests already use both spellings for the attributes converted to the new spelling. No functional changes are expected.

Erich Keane 3bff414cde Fix usage in TableGen of getValueAsString
Record::getValueAsString returns a stringref to an interned
string (apparently had been changed since most of tablegen was
written). In this patch, I audited the usage of getValueAsString
to find places where we can trivially stop storing 'std::string' and instead
keep the stringref.

There was one instance where an unnecessary 'stringstream' was being used,
so that has been removed as well to unblock the stringref replacing string fix.

Erich Keane a98a2be869 Sort Attributes by "HeaderName"
Attributes in the docs were previously sorted (apparently)
by the attribute name, so AnyX86Interrupt ended up being the
first one, rather than in a meaningful place. This resulted in the
4 'interrupt' titled sections being all in different places.

This replaces it with a naive alphabetical sort (case sensitive, underscore
and special characters first, etc).

Alexander Shaposhnikov 0141e556f5 [clang] Enable clang build with LLVM_BUILD_INSTRUMENTED without setting LLVM_PROFTDATA
At the moment if LLVM_BUILD_INSTRUMENTED is set to True 
one has to set LLVM_PROFTDATA even if it's not really used 
(because of message(FATAL_ERROR ...)). 
Building the instrumented version of Clang can be useful even if 
one doesn't plan to build the target generate-profdata
(currently that target would only compile utils/perf-training/cxx/hello_world.cpp).
For example, one can run the instrumented version of Clang 
via a separate build system against a different codebase, 
collect/analyze the profiles and merge them by llvm-profdata later.
