Craig Silverstein 1a9ca21881 Several PPCallbacks take an SourceLocation + IdentifierInfo, rather
than a Token that holds the same information all in one easy-to-use
package.  There's no technical reason to prefer the former -- the
information comes from a Token originally -- and it's clumsier to use,
so I've changed the code to use tokens everywhere.

John McCall 7decc9e4ea Calculate the value kind of an expression when it's created and
store it on the expression node.  Also store an "object kind",
which distinguishes ordinary "addressed" l-values (like
variable references and pointer dereferences) and bitfield,
@property, and vector-component l-values.

Currently we're not using these for much, but I aim to switch
pretty much everything calculating l-valueness over to them.
For now they shouldn't necessarily be trusted.

Argyrios Kyrtzidis 14a96625b8 Don't warn for parentheses for the '&&' inside '||' for cases like:
assert(a || b && "bad");

since this is safe. This way we avoid a big source of such warnings which in this case are practically useless.

Note that we don't handle *all* cases where precedence wouldn't matter because of constants since
this is a bit costly to check, and IMO clarifying precedence with parentheses is good for
readability in general.

Chris Lattner 11feaf5921 When forming the !srcloc mdnode for an inline asm, add the SourceLocations
of all the lines of the inline asm.  With the refactoring and enhancement
of the backend, we can now reports errors on the correct source line when
an asm contains multiple lines of text.  For something like this:

void foo() {
  asm("push %rax\n"
      ".code32\n");
}

we used to get this: (note that the line 4 in t.c isn't helpful)

t.c:4:7: error: warning: ignoring directive for now
  asm("push %rax\n"
      ^
<inline asm>:2:1: note: instantiated into assembly here
.code32
^

now we get:

t.c:5:8: error: warning: ignoring directive for now
      ".code32\n"
       ^
<inline asm>:2:1: note: instantiated into assembly here
.code32
^

Note that we're pointing to line 5 properly now.  This implements
rdar://7839391 - inline asm errors should point to the right line in the asm
and makes the error message in PR8595 much less confusing.

Chandler Carruth 1c8383dccd Fix PR8625 and correctly interpret member-calls to static members when
producing warnings.

This feels really fragile, and I've not audited all other argument index-based
warnings. I suspect we'll grow this bug on another warning eventually. It might
be nice to adjust the argument indices when building up the attribute AST node,
as we already have to remember about the 'this' argument within that code to
produce correct errors.

Chandler Carruth 743682bb9f Re-work the handling of implicit 'this' arguments and silly GCC-style attribute
argument indexes. This handles the offsets in a consistent manner for all of
the attributes which I saw working with these concepts. I've also added tests
for the attribute that motivated this: nonnull.

I consolidated the tests for format attributes into one file, and fleshed them
out a bit to trigger more of the warning cases. Also improved the quality of
some of the diagnostics that occur with invalid argument indices.

The only really questionable change here is supporting the implicit this
argument for the ownership attribute. I'm not sure it's really a sensible
concept there, but implemented the logic for consistency.

before this change.  On the other hand, for code like this:

Bob Wilson 118baf7611 Add support for "neon_vector_type" and "neon_polyvector_type" attributes

Bob Wilson 7795480992 ASTContext::getVectorType should preserve the vector kind for canonical types.
This is needed for Neon types when it is most natural to define them in terms
of a typedef.  For example, Neon poly8_t is a typedef for "signed char", and
we want to define polynomial vectors as vectors of that typedef.  Without this
change, the result will be a generic GCC-style vector.  I think this is safe
for other vector types as well, but I would appreciate a review of this.

of the enumerators rather than the actual expressible range.  This is 
great when dealing with opaque *values* of that type, but when computing
the range of the type for purposes of converting *into* it, it produces
warnings in cases we don't care about (e.g. enum_t x = 500;).  Divide 
the logic into these two cases and use the more conservative range for
targets.

Ted Kremenek 5eec2b0bd3 Region-allocate all AttributeList objects from a factory object instead of manually managing them
using new/delete and OwningPtrs.  After memory profiling Clang, I witnessed periodic leaks of these
objects; digging deeper into the code, it was clear that our management of these objects was a mess.  The ownership rules were murky at best, and not always followed.  Worse, there are plenty of error paths where we could screw up.

This patch introduces AttributeList::Factory, which is a factory class that creates AttributeList
objects and then blows them away all at once.  While conceptually simple, most of the changes in
this patch just have to do with migrating over to the new interface.  Most of the changes have resulted in some nice simplifications.

This new strategy currently holds on to all AttributeList objects during the lifetime of the Parser
object.  This is easily tunable.  If we desire to have more bound the lifetime of AttributeList
objects more precisely, we can have the AttributeList::Factory object (in Parser) push/pop its
underlying allocator as we enter/leave key methods in the Parser.  This means that we get
simple memory management while still having the ability to finely control memory use if necessary.

Note that because AttributeList objects are now BumpPtrAllocated, we may reduce malloc() traffic
in many large files with attributes.

This fixes the leak reported in: <rdar://problem/8650003>

Douglas Gregor 928479e727 Revert the fix for PR8013.
That bug concerned the well-formedness of code such as (&ovl)(a, b,
c). GCC rejects the code, while EDG accepts it. On further study of the
standard, I see no support for EDG's position: in particular, C++
[over.over] does not list this as a context where we can take the
address of an overloaded function, C++ [over.call.func] does not
reference the address-of operator at any point, and C++ [expr.call]
claims that the function argument in a call is either a function
lvalue or a pointer-to-function; (&ovl) is neither.

   work on a unknown one.
*) The distro enum now doesn't include the arch. Just use the existing
   host detection support in LLVM.
*) Correctly handle --sysroot.

A small regression is that now clang will pass bitcode file to the linker.
This is necessary for the gold plugin support to work.

It might be better to detect this at configure/cmake time, but doing it in
c++ first is a lot easier.

Argyrios Kyrtzidis 71731d6b05 Implement -working-directory.
When -working-directory is passed in command line, file paths are resolved relative to the specified directory.
This helps both when using libclang (where we can't require the user to actually change the working directory)
and to help reproduce test cases when the reproduction work comes along.

--FileSystemOptions is introduced which controls how file system operations are performed (currently it just contains
 the working directory value if set).
--FileSystemOptions are passed around to various interfaces that perform file operations.
--Opening & reading the content of files should be done only through FileManager. This is useful in general since
 file operations will be abstracted in the future for the reproduction mechanism.

FileSystemOptions is independent of FileManager so that we can have multiple translation units sharing the same
FileManager but with different FileSystemOptions.

Douglas Gregor f86c939bff When de-serializing a type that is supposed to be canonical, call
getCanonicalType() to make sure that the type we got back is actually
canonical. This is the case for most types, which always build a
canonical type when given canonical components. However, some types that
involve expressions in their canonicalization (e.g., array types with
dependent sizes) don't always build canonical types from canonical
components, because there is no such thing as a "canonical"
expression. Therefore, we do this extra mapping to ensure that the
canonical types we store are actually canonical.

David Chisnall b62d15c24e Only warn for mismatched types in Objective-C methods when they are incompatible, not when they are simply different. Now we test whether the difference in types breaks the principle of substitutability, rather than whether they are different.
A common idiom in Objective-C is to provide a definition of a method in a subclass that returns a more-specified version of an object than the superclass.  This does not violate the principle of substitutability, because you can always use the object returned by the subclass anywhere that you could use the type returned by the superclass.  It was, however, generating warnings with clang, leading people to believe that semantically correct code was incorrect and requiring less accurate type specification and explicit down-casts (neither of which is a good thing to encourage).

This change ensures that any method definition has parameter and return types that make it accept anything that something conforming to the declaration may pass and return something that the caller will expect, but allows stricter definitions.

write. Also some minor cleanups to more consistently follow the friend pattern

Now MICache is a linked list (per the FIXME), where we tradeoff between MacroInfo objects being in MICache
and MIChainHead.  MacroInfo objects in the MICache chain are already "Destroy()'ed", so they can be reused.  When
inserting into MICache, we need to remove them from the regular linked list so that they aren't destroyed more than
once.

The problem was not the management of MacroInfo objects, but that when we recycle them
via the MICache the memory of the underlying SmallVector (within MacroInfo) was not getting
released.  This is because objects stashed into MICache simply are reused with a placement
new, and never have their destructor called.

Douglas Gregor 26c5578d84 When performing typo correction, keep track of whether the last lookup
we did was an acceptable lookup. If it is, then we can re-use that
lookup result. If it isn't, we have to perform the lookup again. This
is almost surely the cause behind the mysterious typo.m failures on
some builders; we were getting the wrong lookup results returned.

Douglas Gregor 57756eabc9 When performing typo correction, look through the set of known
identifiers to determine good typo-correction candidates. Once we've
identified those candidates, we perform name lookup on each of them
and the consider the results. 

This optimization makes typo correction > 2x faster on a benchmark
example using a single typo (NSstring) in a tiny file that includes
Cocoa.h from a precompiled header, since we are deserializing far less
information now during typo correction.

There is a semantic change here, which is interesting. The presence of
a similarly-named entity that is not visible can now affect typo
correction. This is both good (you won't get weird corrections if the
thing you wanted isn't in scope) and bad (you won't get good
corrections if there is a similarly-named-but-completely-unrelated
thing). Time will tell whether it was a good choice or not.
