In earlier patches regarding AnalyzerOptions, a lot of effort went into
gathering all config options, and changing the interface so that potential
misuse can be eliminited.
Up until this point, AnalyzerOptions only evaluated an option when it was
querried. For example, if we had a "-no-false-positives" flag, AnalyzerOptions
would store an Optional field for it that would be None up until somewhere in
the code until the flag's getter function is called.
However, now that we're confident that we've gathered all configs, we can
evaluate off of them before analysis, so we can emit a error on invalid input
even if that prticular flag will not matter in that particular run of the
analyzer. Another very big benefit of this is that debug.ConfigDumper will now
show the value of all configs every single time.
Also, almost all options related class have a similar interface, so uniformity
is also a benefit.
The implementation for errors on invalid input will be commited shorty.

Don't generate a checker-tagged node unconditionally on the first
checkDeadSymbols callback when no pointers are tracked.
This is a tiny performance optimization; it may change the behavior slightly

The checker suppresses warnings on paths on which a nonnull value is assumed
to be nullable. This probably deserves a warning, but it's a separate story.
Now, because dead symbol collection fires in pretty random moments,
there sometimes was a situation when dead symbol collection fired after
computing a parameter but before actually evaluating call enter into the
function, which triggered the suppression when the argument was null
in the first place earlier than the obvious warning for null-to-nonnull
was emitted, causing false negatives.
Only trigger the suppression for symbols, not for concrete values.
It is impossible to constrain a concrete value post-factum because
it is impossible to constrain a concrete value at all.
This covers all the necessary cases because by the time we reach the call,
symbolic values should be either not constrained to null, or already collapsed
into concrete null values. Which in turn happens because they are passed through
the Store, and the respective collapse is implemented as part of getSVal(),
which is also weird.
Differential Revision: https://reviews.llvm.org/D54017
llvm-svn: 347954
It's an old bug that consists in stale references to symbols remaining in the
GDM if they disappear from other program state sections as a result of any
operation that isn't the actual dead symbol collection. The most common example
here is:
FILE *fp = fopen("myfile.txt", "w");
fp = 0; // leak of file descriptor
In this example the leak were not detected previously because the symbol
disappears from the public part of the program state due to evaluating
the assignment. For that reason the checker never receives a notification
that the symbol is dead, and never reports a leak.
This patch not only causes leak false negatives, but also a number of other
problems, including false positives on some checkers.
What's worse, even though the program state contains a finite number of symbols,
the set of symbols that dies is potentially infinite. This means that is
impossible to compute the set of all dead symbols to pass off to the checkers
for cleaning up their part of the GDM.
No longer compute the dead set at all. Disallow iterating over dead symbols.
Disallow querying if any symbols are dead. Remove the API for marking symbols
as dead, as it is no longer necessary. Update checkers accordingly.

The addition adds three attributes for communicating ownership,
analogous to existing NS_ and CF_ attributes.
The attributes are meant to be used for communicating ownership of all
objects in XNU (Darwin kernel) and all of the kernel modules.
The ownership model there is very similar, but still different from the
Foundation model, so we think that introducing a new family of
attributes is appropriate.
The addition required a sizeable refactoring of the existing code for
CF_ and NS_ ownership attributes, due to tight coupling and the fact
that differentiating between the types was previously done using a

Declarations without the attribute were disallowed because it would be
ambiguous which 'target' it was supposed to be on. For example:
void ___attribute__((target("v1"))) foo();
void foo(); // Redecl of above, or fwd decl of below?
void ___attribute__((target("v2"))) foo();
However, a first declaration doesn't have that problem, and erroring
prevents it from working in cases where the forward declaration is
useful.
Additionally, a forward declaration of target==default wouldn't properly
cause multiversioning, so this patch fixes that.
The patch was not split since the 'default' fix would require
implementing the same check for that case, followed by undoing the same
change for the fwd-decl implementation.

There is no reason to emit coverage mappings for artificial statements
contained within defaulted methods, as these statements are not visible
to users.
Only emit a mapping for the body of the defaulted method (clang treats
the text of the "default" keyword as the body when reporting locations).
This allows users to see how often the default method is called, but
trims down the coverage mapping by skipping visitation of the children
of the method.
The immediate motivation for this change is that the lexer's
getPreciseTokenLocEnd API cannot return the correct location when given
an artificial statement (with a somewhat made-up location) as an input.

For the NVPTX target default locations should be emitted as constants +
additional info must be emitted in the reserved_2 field of the ident_t
structure. The 1st bit controls the execution mode and the 2nd bit
controls use of the lightweight runtime. The combination of the bits for
Non-SPMD mode + lightweight runtime represents special undefined mode,
used outside of the target regions for orphaned directives or functions.
Should allow and additional optimization inside of the target regions.

Sanitizer runtime link deps handling passes --no-as-needed because of
PR15823, but it never undoes it and this flag may affect other libraries
that come later on the link line. To avoid this, wrap Sanitizer link
deps in --push/pop-state.

Loop-control variables with the default data-sharing attributes should
not be captured in the OpenMP region as they are private by default.
Also, default attributes should be emitted for such variables in the
inner OpenMP regions for the correct data sharing during codegen.

forms of random access iterator
In OpenMP 4.5, only 4 relational operators are supported: <, <=, >,
and >=. This work is to enable support for relational operator
!= (not-equal) as one of the canonical forms.

Even though these deps weren't needed, this makes Fuchsia driver
better match other drivers, and it may be necessary when trying to
use different C libraries on Fuchsia.

These offsets are useless (and even harmful in certain cases) in exported
diagnostics. The test will be added to clang-tidy, since it's the main user of
the clang::tooling::Diagnostic class.

Summary:
Similar to auto-completion for ObjC methods, inherited properties
should be penalized / direct class and category properties should
be prioritized.
Note that currently, the penalty for using a result from a base class
(CCD_InBaseClass) is equal to the penalty for using a method as a
property (CCD_MethodAsProperty).

This patch adjusts a test not to depend on deprecated FileCheck
behavior that permits overlapping matches within a block of CHECK-DAG
directives. Thus, this patch also removes uses of FileCheck's
-allow-deprecated-dag-overlap command-line option.
There were two issues in this test:
1. There were sets of patterns for store instructions in which a
pattern X could match a superset of a pattern Y. While X appeared
before Y, Y's intended match appeared before X's intended match. The
result was that X matched Y's intended match. Under the old
overlapping behavior, Y also matched Y's intended match. Under the
new non-overlapping behavior, Y had nothing left to match. This patch
fixes this by gathering these sets in one place and putting the most
specific patterns (Y) before the more general patterns (X).
2. The CHECK-DAG patterns involving the variables CBPADDR3 and
CBPADDR4 were the same, but there was only one match in the text, so
CBPADDR4 patterns had nothing to match under the new non-overlapping
behavior. Moreover, a preceding related series of directives had
variables (SADDR0, BPADDR0, etc.) numbered only 0 through 4, but this
series had variables numbered 0 through 5. Assuming CBPADDR4's
directives were not intended, this patch removes them.
