Peter Collingbourne e046199a71 Introduce Go coding standards for LLVM.
Rather than define our own standards, we adopt a set of best practices that
are already in use by the Go community.

Duncan P. N. Exon Smith 38f556d96d CodingStandards: Document std::equal misbehaviour
I should have included this as part of r215986, which worked around this
corner by changing ArrayRef::equals() not to use std::equal.  Alas.

Reid Kleckner 6a8fada294 Remove the recommendation against using std::function
Clang-cl supports MSVC-style RTTI now, and we can even compile
typeid(...) with /GR-.  Just don't instantiate std::function with a
polymorphic type, or bad things will happen.

Sean Silva 1703e705cf [docs] Fix up some links to the preferred style.
:doc:`...` and :ref:`...` links help Sphinx keep track the dependencies
between documents and ensure that they are not pointing to nowhere.

Raw HTML links work just fine and are easier for people less familiar
with reST/Sphinx. They are easy to change over to the :doc:/:ref: style
after the fact so this is not a problem.

This commit doesn't fix all of them.

Duncan P. N. Exon Smith 9948637687 C++11: Beware unnecessary copies with auto
It's easy to copy unintentionally when using 'auto', particularly inside
range-based for loops.  Best practise is to use 'const&' unless there's
a good reason not to.

Duncan P. N. Exon Smith 9724e833ce Clarify struct usage guidelines
The current coding standards restrict the use of struct to PODs, but no
one has been following them.  This patch updates the standards to
clarify when structs are dangerous and describe common practice in LLVM.

Chandler Carruth e55d9bf508 [C++11] Update the coding standards to provide some important guidance
about a few constructs in C++11 that are worth starting off in
a consistent manner within the codebase.

This will be matched with a change to clang-format's LLVM style which
will switch the options to support C++11 and use these conventions.

Chandler Carruth 6e390fae4b [docs] Clarify that there isn't much to be done other than watch build
bots when using the standard library facilities. The missing pieces here
aren't always in useful discreet chunks.

Fortunately, the missing pieces are few and far between, and we can
emulate most of them in our headers as needed.

Based on feedback from Lang and Dave.

Chandler Carruth e8c97895ef [docs] Add a section to the coding standards about languages and such.
A lot of this is writing down common knowledge and things often
communicated on mailing lists and in discussions. It could live in the
Programmer's Manual alternatively, but that felt slightly less
well-fitting.

It also includes (and was motivated by) the section on the relevant
language standards for LLVM and the specific features that will be
enabled with the switch to C++11.

With this, all of the documentation for the C++11 switch is, I think, in
place. I plan to flip the switch RSN. =]

Chandler Carruth c8ce0659f2 [docs] A slight tweak to the intro for the golden rule in the coding
standards.

It claims the document intentionally doesn't give fixed standards for
brace placement or spacing, and then the document goes on to do
precisely that in several places. Instead, try to highlight that even
these rules are simply *guidance* which may be trumped by some other
circumstance or the local conventions of code.

I'm not trying to change the thrust of this part of the document, and if
folks think this does so, I'm happy to re-wordsmith it. I just don't
want it to be so self-contradicting.

Chandler Carruth 36dc51910a Revert my commit in r199620 that added sections about namespaces to the
coding standards, and instead fix the existing section.

Thanks to Daniel Jasper for pointing out we already had a section
devoted to this topic. Instead of adding sections, just hack on this
section some. Also fix the example in the anonymous namespace section
below it to agree with the new advice.

As a re-cap, this switches the LLVM preferred style to never indent
namespaces. Having two approaches just led to endless (and utterly
pointless) debates about what was "small enough". This wasn't helping
anyone. The no-indent rule is easy to understand and doesn't really make
anything harder to read. Moreover, with tools like clang-format it is
considerably nicer to have simple consistent rules.

llvm-svn: 199637
2014-01-20 10:15:32 +00:00
Chandler Carruth 8660df47e5 Add some wording to the coding standards to say how to indent namespaces
(and to mention namespace ending comments). This is based on a quick
discussion on the developer mailing list where there was essentially no
objections to a simple and consistent rule. This should avoid future
debates about whether or not a namespace is "big enough" to indent. It
also matches clang-format's current behavior with LLVM source code which
hasn't really seen any opposition in code reviews that I spot checked.
