for adjusting the high bounds of case ranges
before APSInt comparisons. Fixes

one results in an obscure error from the backend that doesn't make
sense. Capture this information in the .def files for builtins with
a new "I" modifier letter indicating the an argument needs to be an ICE.
Nothing uses this yet, but sema will eventually enforce this (eliminating
some special cases from semachecking.cpp) and codegen will use this to
force an ICE value, preventing backend error messages.

file is somehow changed in a chained PCH file, make sure that we write
out the macro definition. Fixes part of <rdar://problem/8499034>.

- Adding LocalScope for CompoundStmt,
- Adding CFGAutomaticObjDtors for end of scope, return, goto, break, continue,
- Regression tests for above cases.

- post-increament, distance and bool conversion methods to LocalScope::const_iterator,
- adding VarDecl to LocalScope.
Fixed some misspells in comments.

In this experimental mode try avoiding debug info emission for classes as much as possible. The goal is to reduce size of produced debuginfo without reducing quality of debug info in general. This is a work in progress.

- Idempotent operations are on by default, to match --analyze in the driver.
- Integrated stats calculation based on parsing warnings emitted with the -analyzer-stats flag. The new -stats flag enables this.
- New -maxloop flag to pass down a maxloop value to the analyzer.

all CallExprs (including CXXMemberCallExpr, etc.). Now the generic handler for all CallExprs is [Pre,Post]VisitGenericCallExpr.
Also add [Pre,Post]Visit hooks for CXXMemberCallExpr.
Change GRExprEngine::VisitCXXMemberCallExpr() to do pre/post checker visits of the call.
llvm-svn: 115119
- Use BlockEntrance rather than BlockEdge to bring in line with UnreachableCodeChecker. Fixes an issue where unreached blocks would still be counted as reachable.
- Added warnings for all BlockAborted locations. This allows us to see where the analyzer stopped analyzing.

against a function type, be sure to check the type of the resulting
function template specialization against the desired function type
after substituting the deduced/defaulted template arguments. Fixes PR8196.
llvm-svn: 115086
- I don't like returning StringRef's ever, unless it is actually important for
performance, which it isn't here.
- Also, stop validating getClangRevision to be an integer, I don't see a good
reason to do this.

into CXXRecordDecl. The only part that we do not handle this way are
using declarations, since that would require extra name lookup that we
don't currently want to pay for. This fixes <rdar://problem/8459981>,
so that LLDB can build a CXXRecordDecl and magically get all of the
right bits set.
llvm-svn: 115026
completely into CXXRecordDecl, by adding a new completeDefinition()
function. This required a little reshuffling of the final-overrider
checking code, since the "abstract" calculation in the presence of
abstract base classes needs to occur in
CXXRecordDecl::completeDefinition() but we don't want to compute final
overriders more than one in the common case.
llvm-svn: 115007
in CXXRecordDecl itself. Yes, this is also part of <rdar://problem/8459981>.
This reinstates r114924, with one crucial bug fix: we were ignoring
the implicit fields created by anonymous structs/unions when updating
the bits in CXXRecordDecl, which means that a class/struct containing
only an anonymous class/struct would be considered "empty". Hilarity
follows.
llvm-svn: 114980
Centralize the management of CXXRecordDecl::DefinitionData's Aggregate
and PlainOldData bits in CXXRecordDecl itself. Another milepost on the
road toward <rdar://problem/8459981>.
llvm-svn: 114977
verify that we aren't in a message-send expression before digging into
the identifier or looking ahead more tokens. Fixes a regression

HasTrivialConstructor, HasTrivialCopyConstructor,
HasTrivialCopyAssignment, and HasTrivialDestructor bits in
CXXRecordDecl's methods. This completes all but the Abstract bit and
the set of conversion functions, both of which will require a bit of
extra work. The majority of <rdar://problem/8459981> is now
implemented (but not all of it).

already be determined by isCopyAssignmentOperator(), and was set too
late in the process for all clients to see the appropriate

llvm-svn: 114916
DeclaredCopyConstructor bits in CXXRecordDecl's DefinitionData
structure. Rather than having Sema call addedConstructor or set the
bits directly at semi-random places, move all of the logic for
managing these bits into CXXRecordDecl itself and tie the
addedConstructor call into DeclContext::addDecl().
This makes it easier for AST-building clients to get the right bits
set in DefinitionData, and is one small part of <rdar://problem/8459981>.

- LocalScope class with iterator used to pointing into it,

identifier, we may have a Sema object but no translation unit scope
(because parsing is finished). In this case, we still need to update
the IdResolver, which might still be used when writing a PCH
containing another PCH (without chaining). This bug manifested as a
failure with precompiled preambles.
Also, add a little environment-variable-sensitive logging for
libclang.

provided when the optimization is disabled. In particular, split
the completion context CCC_Other into two contexts: CCC_Other, which
means that it's an undisclosed context for which any other results are
unwelcome, and CCC_Recovery, which is used in recovery cases.
Since we're now using the completion context within the completion
results builder, make sure that it's always set to something.
Fixes <rdar://problem/8470644>.

- Therefore, we can lower out the NEON wrapper structs and pass the vectors
directly. This makes a huge difference in the cleanliness of the IR after
optimization.
- I will trust, but verify, via future ABITest testing (for APCS-GNU, at
least).
