instead of a get() method we find in the class.
The duck typed smart pointer class could have overloaded get() methods
and we should only skip the one that matches.

Expand the simplify boolean expression check to handle implicit conversion of integral types to bool and improve the handling of implicit conversion of member pointers to bool.
Implicit conversion of member pointers are replaced with explicit comparisons to nullptr.
Implicit conversions of integral types are replaced with explicit comparisons to 0.
Patch by Richard Thomson.
llvm-svn: 260681
Summary:
The check will trigger a assert failure("CondEndLoc.isValid") when
checking the IfStmt whose condition expression is not parsed.
In this case, we should ignore that.

Summary:
This patch is provided in preparation for removing autoconf on 1/26. The proposal to remove autoconf on 1/26 was discussed on the llvm-dev thread here: http://lists.llvm.org/pipermail/llvm-dev/2016-January/093875.html

This changeset still emits the diagnostic that the expression could be simplified, but it doesn't generate any fix-its that would lose comments or preprocessor directives within the text that would be replaced.

With this change the error reported is on the identifier location
itself. It was declaration location before.

Summary:
This is another check that I ported to clang-tidy from colobot-lint tool.
As previously discussed on cfe-dev mailing list, this is one of those
checks that I think is general and useful enough for contribution to
clang-tidy.
This patch contains implementation of check taken from colobot-lint, but
it is extended a great deal, including FixIt hints for automated
refactoring, exhaustive testcases, and user documentation.

This diff requires http://reviews.llvm.org/D13079 to be applied first. I wasn't sure about how to make patch series in Phabricator, and I wanted to keep the two separate for clarity.
It looks like that most cases can be supported with this patch. I'm not totally sure about the actual coverage though. I think that the matchers are very generic, but I'm still not totally fluent with the AST.

This is to level the ground a little bit, in preparation for the changes in http://reviews.llvm.org/D13081.
Code factorization replaces all insertions to NamingCheckFailures map with a unique addUsage function that does the job.
There is also no more difference between the declaration and the references to a given identifier, both cases are treated as ranges in the Usage vector. There is also a check to avoid duplicated ranges to be inserted, which sometimes triggered erroneous replacements.
References can now also be added before the declaration of the identifier is actually found; this looks to be the case for example when a templated class uses its parameters to specialize its templated base class.

This is first of series of patches, porting code from my project colobot-lint,
as I mentioned recently in cfe-dev mailing list.
This patch adds a new check in readability module:
readability-inconsistent-declaration-parameter-name. I also added appropriate
testcases and documentation.
I chose readability module, as it seems it is the best place for it.
I think I followed the rules of LLVM coding guideline, but I may have missed
something, as I usually use other code formatting style.

llvm-svn: 247261
Changes mostly address formatting and unification of the style. Use
MarkDown style for inline code snippets and lists. Added some text
for a few checks.
The idea is to move most of the documentation out to separate rST files and have
implementation files refer to the corresponding documentation files.
llvm-svn: 246169
This check will try to enforce coding guidelines on the identifiers naming.
It supports lower_case, UPPER_CASE, camelBack and CamelCase casing and
tries to convert from one to another if a mismatch is detected.
It also supports a fixed prefix and suffix that will be prepended or appended
to the identifiers, regardless of the casing.
Many configuration options are available, in order to be able to create
different rules for different kind of identifier. In general, the
rules are falling back to a more generic rule if the specific case is not
configured.

Enhance clang-tidy readability-simplify-boolean-expr to handle 'if (e) return
true; return false;' and improve replacement expressions.
This changeset extends the simplify boolean expression check in clang-tidy to
simplify if (e) return true; return false; to return e; (note the lack of an
else clause on the if statement.) By default, chained conditional assignment is
left unchanged, unless a configuration parameter is set to non-zero to override
this behavior.
It also improves the handling of replacement expressions to apply
static_cast<bool>(expr) when expr is not of type bool.

llvm-svn: 241155
Enhance clang-tidy readability-simplify-boolean-expr check to handle chained
conditional assignment and chained conditional return.
Based on feedback from applying this tool to the clang/LLVM codebase, this
changeset improves the readability-simplify-boolean-expr check so that
conditional assignment or return statements at the end of a chain of if/else if
statements are left unchanged unless a configuration option is supplied.

The number of strings is so small that performance doesn't matter and adding
the thread safe static initialization and destruction overhead is just not
worth it. No functional change intended.
llvm-svn: 235192
This check looks for comparisons between boolean expressions and boolean
constants and simplifies them to just use the appropriate boolean expression
directly.
if (b == true) becomes if (b)
if (b == false) becomes if (!b)
if (b && true) becomes if (b)
if (b && false) becomes if (false)
if (b || true) becomes if (true)
if (b || false) becomes if (b)
e ? true : false becomes e
e ? false : true becomes !e
if (true) t(); else f(); becomes t();
if (false) t(); else f(); becomes f();
if (e) return true; else return false; becomes return (e);
if (e) return false; else return true; becomes return !(e);
if (e) b = true; else b = false; becomes b = e;
if (e) b = false; else b = true; becomes b = !(e);

Summary:
Force braces on the else branch if they are being added to the if branch.
This ensures consistency in the transformed code.
