285cfd8953d4ca4da613a47a0d691f7234068f8c 19-Sep-2011 Bill Wendling <isanbard@gmail.com> Throw the switch to convert clang to the new exception handling model!

This model uses the 'landingpad' instruction, which is pinned to the top of the
landing pad. (A landing pad is defined as the destination of the unwind branch
of an invoke instruction.) All of the information needed to generate the correct
exception handling metadata during code generation is encoded into the
landingpad instruction.

The new 'resume' instruction takes the place of the llvm.eh.resume intrinsic
call. It's lowered in much the same way as the intrinsic is.

777d6e56ad9b1fed9866daf3ee6486d85c5b7d32 11-Aug-2011 John McCall <rjmccall@apple.com> Simplify EH control flow by observing that EH scopes form a simple
hierarchy of delegation, and that EH selector values are meaningful
function-wide (good thing, too, or inlining wouldn't work).

hierarchy of delegation and that EH selector values have the same
meaning everywhere in the function instead of being meaningful only
in the context of a specific selector.

This removes the need for routing edges through EH cleanups,
since a cleanup simply always branches to its enclosing scope.

82cd2e5c15aa909ec9613c4228ab69e07f1c6f7a 06-Aug-2011 John McCall <rjmccall@apple.com> Be sure to destroy the normal entry block of a cleanup that we
aren't actually going to make a normal cleanup for. Sometimes
we optimistically create branches to such blocks for fixups,
and then we resolve the fixup to somewhere within the cleanup's
scope, and then the cleanup is actually not reachable for some
reason. The process of resolving the fixup leaves us with
switches whose default edge leads to the cleanup; we can
replace that with unreachable, then (in many cases) turn
the switch into an unconditional branch.

Fixes PR10467.

2673c68aa58e277ebc755b71d81aca618cdedbf9 11-Jul-2011 John McCall <rjmccall@apple.com> Fix a lot of problems with the partial destruction of arrays:
- an off-by-one error in emission of irregular array limits for
InitListExprs
- use an EH partial-destruction cleanup within the normal
array-destruction cleanup
- get the branch destinations right for the empty check
Also some refactoring which unfortunately obscures these changes.

- Emit default-initialization of arrays that were partially initialized
with initializer lists with a loop, rather than emitting the default
initializer N times;
- support destroying VLAs of non-trivial type, although this is not
yet exposed to users; and
- support the partial destruction of arrays initialized with
initializer lists when an initializer throws an exception.

self-host. Hopefully these results hold up on different platforms.

I tried to keep the GNU ObjC runtime happy, but it's hard for me to test.
Reimplement how clang generates IR for exceptions. Instead of creating new
invoke destinations which sequentially chain to the previous destination,
push a more semantic representation of *why* we need the cleanup/catch/filter
behavior, then collect that information into a single landing pad upon request.

Also reorganizes how normal cleanups (i.e. cleanups triggered by non-exceptional
control flow) are generated, since it's actually fairly closely tied in with
the former. Remove the need to track which cleanup scope a block is associated
with.

Document a lot of previously poorly-understood (by me, at least) behavior.

The new framework implements the Horrible Hack (tm), which requires every
landing pad to have a catch-all so that inlining will work. Clang no longer
requires the Horrible Hack just to make exceptions flow correctly within
a function, however. The HH is an unfortunate requirement of LLVM's EH IR.

aren't dropping all exception specifications on destructors, the
exception specifications on implicitly-declared destructors were
detected as being wrong (which they were).

Introduce logic to provide a proper exception-specification for
implicitly-declared destructors. This also fixes PR6972.

Note that the other implicitly-declared special member functions also
need to get exception-specifications. I'll deal with that in a
subsequent commit.

c0bf462cf35fe050bddbd8bff967298e4a67e79d 23-Feb-2010 John McCall <rjmccall@apple.com> Perform two more constructor/destructor code-size optimizations:

1) emit base destructors as aliases to their unique base class destructors
under some careful conditions. This is enabled for the same targets that can
support complete-to-base aliases, i.e. not darwin.

2) Emit non-variadic complete constructors for classes with no virtual bases
as calls to the base constructor. This is enabled on all targets and in
theory can trigger in situations that the alias optimization can't (mostly
involving virtual bases, mostly not yet supported).

These are bundled together because I didn't think it worthwhile to split them,
not because they really need to be.

Fix some bugs with function-try-blocks and simplify normal try-block

This implementation excludes a deleting destructor's call to

is correct but which I can't find straightforward support for at
a moment's glance.

- This is designed to make it obvious that %clang_cc1 is a "test variable"

can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).
