docs: Convert ReleaseNotes to reST.
This is the last of the "regular" documents to convert to reST, and so
I'm declaring the initial clang reST conversion "done".
However,
- There are some documents in clang/www/ which probably should
be migrated into clang/docs/, such as www/OpenProjects.html
The primary thing blocking me from doing this right now is not knowing
how to set up a redirect so that the old URL's continue to work.
- LibASTMatchersReference.html is not reST. This page is auto-generated
by clang/docs/tools/dump_ast_matchers.py from the source and has some
collapse/expand logic that isn't expressible directly with Sphinx, so
just converting it to reST is not really a good strategy.
Manuel Klimek and I discussed this and the general agreed-upon
direction is making that page data-driven so that it, say, pulls in an
auto-generated blob of JSON which describes the matchers and builds up
the "matcher reference" part of the page with a small amount of JS.
- There are some rogue .txt files hanging around.
Also, I dropped the little dragon logo at the top because Sphinx was
warning about an external image reference (not sure why, but meh, I
didn't want to fight it). If anything, we would want such a logo
integrated into the site's overall theme, rather than hardcoded here.

Some of the major new features and improvements to Clang are listed

here. Generic improvements to Clang as a whole or to its underlying

|
|

infrastructure are described first, followed by language-specific

sections with improvements to Clang's support for those languages.

- Clang uses the new MingW ABI
|
|
|
|
|
GCC 4.7 changed the mingw ABI. Clang 3.4 and older use the GCC 4.6

ABI. Clang 3.5 and newer use the GCC 4.7 abi.

The integrated assembler is now turned on by default on ARM (and Thumb),
|
|
|
|
|
so the use of the option `-integrated-as` is now redundant on those
|
|
|
|
|
architectures. This is an important move to both *eat our own dog food*
|
|
|
|
|
and to ease cross-compilation tremendously.
|
|
|
|
|
|
|
|
|
|
We are aware of the problems that this may cause for code bases that
|
|
|
|
|
rely on specific GNU syntax or extensions, and we're working towards
|
|
|
|
|
getting them all fixed. Please, report bugs or feature requests if
|
|
|
|
|
you find anything. In the meantime, use `-no-integrated-as` to revert
|
|
|
|
|
back the call to GNU assembler.
