at MCInstPrinter construction time instead of being able
to pick at each call to printInstruction.

Reapply patch for adding support for address spaces and added a isVolatile field to memcpy, memmove, and memset.

llvm-svn: 100305

Added support for address spaces and added a isVolatile field to memcpy, memmove, and memset,
e.g., llvm.memcpy.i32(i8*, i8*, i32, i32) -> llvm.memcpy.p0i8.p0i8.i32(i8*, i8*, i32, i32, i1)

a few more things in AsmPrinter.cpp.

EmitInlineAsm.  However, this attempt is foiled by operands
being emitted directly to "O" so I'll have to do some surgery
and finish MCizing the world.

If we have an MCAsmStreamer, we continue to emit asm textually, 
otherwise we (currently) emit an error to errs and ignore it.

exits the loop.  With this information we can guarantee 
the iteration count of the loop is bounded by the 
compare.  I think this xforms is finally safe now.

checker.  Amusingly, we already had tests that we should
have rejects because they would be miscompiled in the
testsuite.

The remaining issue with this is that we don't check that
the branch causes us to exit the loop if it fails, so we
don't actually know if we remain in bounds.

to a signed vs unsigned value depending on the sign of the
constant fp means that we can't distinguish between a 
truly negative number and a positive number so large the
32nd bit is set.  So, do don't this!

the required validity checks in the first place, and supporting
a condition large enough to require the 32'nd bit isn't worth it.

correct location.

Also, more cleanups.

llvm-svn: 100271

this cleans up a bunch of code and also fixes several crashes and
miscompiles.  More to come unfortunately, this optimization
is quite broken.

really just declarations.  This is related to PR6524

llvm-svn: 100268

llvm-svn: 100267

Don't produce a vtable for a class if we have an explicit template instantiation declaration and no key function. We will produce the vtable at the explicit template instantiation.

Fixes PR6748

abstraction it brings.  And also get rid of the atexit() handler, it does not
belong in the lib directory. :-)

llvm-svn: 100265

(what was I thinking?) and there's also a problem with LCSSA.  I'll try again
later with fixes.
