Chris Lattner dbbdc79267 convert all the constant range EXPECT_EQ tests to use EXPECT_TRUE since 
ConstantRange doesn't have an std::ostream inserter anymore.

Benjamin Kramer 9ace8b5763 Fix unit test on FreeBSD. We need to make sure there is enough space to save the pointer even if the memory returned from malloc was already aligned.

Jeffrey Yasskin 6bf87df579 To catch bugs like the one fixed in 
http://llvm.org/viewvc/llvm-project?view=rev&revision=78127, I'm changing the
ExecutionEngine's global mappings to hold AssertingVH<const GlobalValue>. That
way, if unregistering a mapping fails to actually unregister it, we'll get an
assert. Running the jit nightly tests didn't uncover any actual instances of
the problem.

This also uncovered the fact that AssertingVH<const X> didn't work, so I fixed
that too.

Owen Anderson 5a1acd9912 Move a few more APIs back to 2.5 forms. The only remaining ones left to change back are 
metadata related, which I'm waiting on to avoid conflicting with Devang.

Reid Kleckner 4b1f2f4779 Added a test and fixed a bug in BumpPtrAllocator relating to large alignment 
values.  Hopefully this fixes PR4622.

Reid Kleckner c2d882dd1a Re-committing changes from r76825 to BumpPtrAllocator with a fix and tests for 
an off-by-one error.

Reid Kleckner 921673225c Reverting r76825 and r76828, since they caused clang runtime errors and some build failure involving memset.

Reid Kleckner 5bd6105d65 Parameterize the BumpPtrAllocator over a slab allocator. It defaults to using 
malloc, so there should be no functional changes to other code.

These changes are necessary since I have plans to use this allocator in the JIT
memory manager, and it needs a special allocator.

I also added some tests which helped me pinpoint some bugs.

Nick Lewycky 567daf3ce8 Fix ConstantRange::unionWith. Also make it work a little hard in some cases to 
return the smallest union of two ranges instead of just any range that happens
to contain the union.

Nick Lewycky 0d13903563 Replace intersectWith with maximalIntersectWith. The latter guarantees that 
all values belonging to the intersection will belong to the resulting range.
The former was inconsistent about that point (either way is fine, just pick
one.) This is part of PR4545.

again to Daniel Dunbar and KLEE!

Nick Lewycky 5edc459220 'i8 full-range' sign extended to i16 should equal [-128, 128) not [-128, 127).

Owen Anderson 53a52215b5 Begin the painful process of tearing apart the rat'ss nest that is Constants.cpp and ConstantFold.cpp. 
This involves temporarily hard wiring some parts to use the global context.  This isn't ideal, but it's
the only way I could figure out to make this process vaguely incremental.

Nick Lewycky 5302389442 Multiply was very wrong for wrapped ranges. This supplies a half-fix that will 
generally return Full on all wrapped inputs. "Fixes" PR4545.

Nick Lewycky 73b704dd9c Fix a bug summing two full sets. The overflow checking doesn't handle sets as 
large as the full set, only those one size smaller. Thanks to Daniel Dunbar
who found this bug using Klee!

Nick Lewycky 071e176667 This is not overly conservative. 
Some = [10, 2730). A subset of that is [1024..2048) which covers every possible
10-bit pattern.

Nick Lewycky fc69ee2cc6 Fix handling of max and full set. 
A full set is a constant range that represents any number. If you take the
umax of that and [5, 10) you end up with [5, INT_MAX] because the values less
than 5 would be umax's against a value which is at least 5.

Dan Gohman dc33ae27ed Revert the part of 75177 that split ConstantRange into two classes, and 
merge the new functionality and unittests into ConstantRange. Thanks to
Nick Lewycky for pointing out that it isn't necessary to have two separate
classes here.

llvm-svn: 75191
 2009-07-09 23:16:10 +00:00
Dan Gohman 5035fbf91c Add a ConstantSignedRange class, which does for signed integers 
what ConstantRange does for unsigned integers. Factor out a
common base class for common functionality.

Add some new functions for performing arithmetic on constant
ranges. Some of these are currently just stubbed out with
conservative implementations.

Add unittests for ConstantRange and ConstantSignedRange.

Dan Gohman 745ad4486e Apply Jeffrey Yasskin's CallbackVH patch, with minor tweaks from me 
to make the copy constructor and destructor protected, and corresponding
adjustments to the unittests.

Jeffrey Yasskin 41f2477a50 Add tests for WeakVH and AssertingVH. These pointed out that the overloads for 
the comparison operators were not only unnecessary in the presence of the
implicit conversion; they caused ambiguous overload errors. So I deleted them.
