In the source
static void f();
static void f();
template<typename T>
static void g() {
f();

static void f() {

void h() {

}
the call to f refers to the second decl, but it is only marked used at the end
of the translation unit during instantiation, after the third f decl has been
linked in.
With this patch we mark all subsequent decls used, so that it is easy to check
if a symbol is used or not.

In Clang/LLVM this seems to be the more common formatting for ##s. There
might still be case that we miss, but we'll fix those as we go along.
Before:

After:
#define A(X)
void function##X();

This is a first step towards supporting more complex structures such
as #ifs inside unwrapped lines. This patch mostly converts the array-based
UnwrappedLine into a linked-list-based UnwrappedLine. Future changes will
allow multiple children for each Token turning the UnwrappedLine into a
tree.
No functional changes intended.

The issue here is that if we have 2 leaks reported at the same line for
which we cannot print the corresponding region info, they will get
treated as the same by issue_hash+description. We need to AUGMENT the
issue_hash with the allocation info to differentiate the two issues.
Add the "hash" (offset from the beginning of a function) representing
allocation site to solve the issue.
We might want to generalize solution in the future when we decide to
track more than just the 2 locations from the diagnostics.
llvm-svn: 171825
This is in preparation for using this to construct the function type for
pointers to member functions to include the implicit/artificial 'this'
parameter in that case as well. (feedback from GDB indicates that this might be
all that's necessary to get it to behave well with Clang's pointer-to-member
function debug output)

When a property is "inherited" through both a parent class and directly
through a protocol, we should not require the child to invalidate it
since the backing ivar belongs to the parent class.

Previous indent:
class A {
}
a;
void f() {
};
With this patch:
class A {
} a;
void f() {
}
;
The patch introduces a production for classes and structs, and parses
the rest of the line to the semicolon after the class scope.
This allowed us to remove a long-standing wart in the parser that would
just much the semicolon after any block.
Due to this suboptimal formating some tests were broken.
Some unrelated formatting tests broke; those hit a bug in the ast
printing, and need to be fixed separately.

Following r168626, in class declaration or definition, there are a combination of syntactic locations
where C++11 attributes could appear, and among those the only valid location permitted by standard is
between class-key and class-name. So for those attributes appear at wrong locations, fixit is used to
move them to expected location and we recover by applying them to the class specifier.

This addresses llvm.org/PR14830.
Before:
unsigned Cost =
TTI.getMemoryOpCost(I->getOpcode(), VectorTy, SI->getAlignment(),
SI->getPointerAddressSpace());
CharSourceRange LineRange =
CharSourceRange::getTokenRange(TheLine.Tokens.front().Tok.getLocation(),
TheLine.Tokens.back().Tok.getLocation());
After:
unsigned Cost = TTI.getMemoryOpCost(I->getOpcode(), VectorTy,
SI->getAlignment(),
SI->getPointerAddressSpace());
CharSourceRange LineRange = CharSourceRange::getTokenRange(
TheLine.Tokens.front().Tok.getLocation(),
TheLine.Tokens.back().Tok.getLocation());
This required rudimentary changes to static initializer lists, but we
are not yet formatting them in a reasonable way. That will be done in a
subsequent patch.

This addresses llvm.org/PR14815.
To implement this I introduced a line type during parsing and moved the
definition of TokenType out of the struct for increased readability.
Should have done the latter in a separate patch, but it would be hard to
pull apart now.

The case that we wanted to write a test for cannot happen, as the
UnwrappedLineParser already protects against it. Added an assert to
prevent regressions of that assumption.

First check only wrapped with i==8, second wrapped at i==2,8,18,28,...
This fix restores the intended behavior: i==8,18,28,...
Found with -fsanitize=integer.

We would format:
#define A \
int f(a); int i;
as
#define A \
int f(a);\
int i
The fix will break up macro definitions that could fit a line, but hit
the last column; fixing that is more involved, though, as it requires
looking at the following line.
llvm-svn: 171715
Previously, we'd format
int i;\
// comment
as
int i; // comment
The problem is that the escaped newline is part of the next token, and
thus the raw token text of the comment doesn't start with "//".
llvm-svn: 171713
If a token follows directly on an escaped newline, the escaped newline
is stored with the token. Since we re-layout escaped newlines, we need
to treat them just like normal whitespace - thus, we need to increase
the whitespace-length of the token, while decreasing the token length
(otherwise the token length contains the length of the escaped newline
and we double-count it while indenting).
llvm-svn: 171706
Using added LLVM functionality in r171698. This works in GDB for member
variable pointers but not member function pointers. See the LLVM commit and
GDB bug 14998 for details.
Un-xfailing cases in the GDB 7.5 test suite will follow.
llvm-svn: 171699
If we find an unexpected closing brace, we must not stop parsing, as
we'd otherwise not layout anything beyond that point.
If we find a structural error on the highest level we'll not re-indent
anyway, but we'll still want to format within unwrapped lines.
Needed to introduce a differentiation between an expected and unexpected
closing brace.
llvm-svn: 171666
To parse # correctly, we need to know whether it is the first token in a
line - we can deduct this either from the whitespace or seeing that the
token is the first in the file - we already calculate this information.
This patch moves the identification of the first token into the
getNextToken method and stores it inside the FormatToken, so the
UnwrappedLineParser can stay independent of the SourceManager.
llvm-svn: 171640
Catch some cases I'd missed in r171605 related to unnamed parameters of record

It is somewhat hard to test linkage, so I decided to try to add an assert. This

Some of this is still pretty rough (note the load of FIXMEs), but it is
strictly an improvement and fixes various bugs that were related to
macro processing but are also imporant in non-macro use cases.
Specific fixes:
- correctly puts espaced newlines at the end of the line
- fixes counting of white space before a token when escaped newlines are
present
- fixes parsing of "trailing" tokens when eof() is hit
- puts macro parsing orthogonal to parsing other structure
- general support for parsing of macro definitions
Due to the fix to format trailing tokens, this change also includes a
bunch of fixes to the c-index tests.

Fixes:

This fixes llvm.org/PR14786.
We will need to split there as a last resort, but that should be done
consistently independent of whether the type is a template type or not.

After:

This is the first step towards handling preprocessor directives. This

and causes problems to -fvisibility-inlines-hidden if the cache was not
invalidated.
Original message:
Cache visibility of decls.
This unifies the linkage and visibility caching. I first implemented this when
working on pr13844, but the previous fixes removed the performance advantage of
this one.
This is still a step in the right direction for making linkage and visibility
cheap to use.

This prevents formattings like this (assuming "parameter" doesn't fit the line):
bool f = someFunction() && someFunctionWithParam(
parameter) && someOtherFunction();
Here, "parameter" - the start of line 2 - has a parenthesis level of 2, but
there are subsequent tokens ("&&" and "someOtherFunction") with a lower level.
This is bad for readability as "parameter" hides "someOtherFunction". With this
patch, this changes to:
bool f = someFunction() &&
someFunctionWithParam(parameter) &&
someOtherFunction();

With this patch, splitting after binary operators has a panelty corresponding

if (aaaaaaaaaaaaaaaaaaaaaaaaa ||
bbbbbbbbbbbbbbbbbbbbbbbbb && ccccccccccccccccccccccccc) { .. }

Commit message for r170826:
[analyzer] Traverse the Call Graph in topological order.
Modify the call graph by removing the parentless nodes. Instead all
nodes are children of root to ensure they are all reachable. Remove the
tracking of nodes that are "top level" or global. This information is
not used and can be obtained from the Decls stored inside
CallGraphNodes.
Instead of existing ordering hacks, analyze the functions in topological
order over the Call Graph.
Together with the addition of devirtualizable ObjC message sends and
blocks to the call graph, this gives around 6% performance improvement
on several large ObjC benchmarks.

We used to not really format them. Now we do:
