There is a Constant with non-constant operands: blockaddress.

Fix a scalability issue with complex ConstantExprs.2013-04-13T12:53:18ZBenjamin Kramerbenny.kra@googlemail.com2013-04-13T12:53:18Zurn:sha1:8848680ce0ab416cb646d0a03aa6f4f6f25e7623
This is basically the same fix in three different places. We use a set to avoid
walking the whole tree of a big ConstantExprs multiple times.
For example: (select cmp, (add big_expr 1), (add big_expr 2))
We don't want to visit big_expr twice here, it may consist of thousands of
nodes.
The testcase exercises this by creating an insanely large ConstantExprs out of
a loop. It's questionable if the optimizer should ever create those, but this
can be triggered with real C code. Fixes PR15714.

Move all of the header files which are involved in modelling the LLVM IR2013-01-02T11:36:10ZChandler Carruthchandlerc@gmail.com2013-01-02T11:36:10Zurn:sha1:0b8c9a80f20772c3793201ab5b251d3520b9cea3
into their new header subdirectory: include/llvm/IR. This matches the
directory structure of lib, and begins to correct a long standing point
of file layout clutter in LLVM.
There are still more header files to move here, but I wanted to handle
them in separate commits to make tracking what files make sense at each
layer easier.
The only really questionable files here are the target intrinsic
tablegen files. But that's a battle I'd rather not fight today.
I've updated both CMake and Makefile build systems (I think, and my
tests think, but I may have missed something).
I've also re-sorted the includes throughout the project. I'll be
committing updates to Clang, DragonEgg, and Polly momentarily.

Use the new script to sort the includes of every file under lib.2012-12-03T16:50:05ZChandler Carruthchandlerc@gmail.com2012-12-03T16:50:05Zurn:sha1:d04a8d4b33ff316ca4cf961e06c9e312eff8e64f
Sooooo many of these had incorrect or strange main module includes.
I have manually inspected all of these, and fixed the main module
include to be the nearest plausible thing I could find. If you own or
care about any of these source files, I encourage you to take some time
and check that these edits were sensible. I can't have broken anything
(I strictly added headers, and reordered them, never removed), but they
may not be the headers you'd really like to identify as containing the
API being implemented.
Many forward declarations and missing includes were added to a header
files to allow them to parse cleanly when included first. The main
module rule does in fact have its merits. =]

not.

Get rid of static constructors for pass registration. Instead, every pass exposes an initializeMyPassFunction(), which2010-10-19T17:21:58ZOwen Andersonresistor@mac.com2010-10-19T17:21:58Zurn:sha1:081c34b725980f995be9080eaec24cd3dfaaf065
must be called in the pass's constructor. This function uses static dependency declarations to recursively initialize
the pass's dependencies.
Clients that only create passes through the createFooPass() APIs will require no changes. Clients that want to use the
CommandLine options for passes will need to manually call the appropriate initialization functions in PassInitialization.h
before parsing commandline arguments.
I have tested this with all standard configurations of clang and llvm-gcc on Darwin. It is possible that there are problems
with the static dependencies that will only be visible with non-standard options. If you encounter any crash in pass
registration/creation, please send the testcase to me directly.
