* Use an export list when building JIT unittests. <rdar://problem/12473675>Bob Wilson2012-10-18
| | | | | | | | | When building with LTO, the internalize pass is hiding some global symbols that are necessary for the JIT unittests. It seems like that may be a bug in LTO to do that by default, but until that gets fixed, this change makes sure that we export the necessary symbols for the tests to pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166220 91177308-0d34-0410-b5e6-96231b3b80d8

* Casting.h: Automatically handle isa<Base>(Derived).Sean Silva2012-10-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | Additionally, all such cases are handled with no dynamic check. All `classof()` of the form class Foo { [...] static bool classof(const Bar *) { return true; } [...] } where Foo is an ancestor of Bar are no longer necessary. Don't write them! Note: The exact test is `is_base_of<Foo, Bar>`, which is non-strict, so that Foo is considered an ancestor of itself. This leads to the following rule of thumb for LLVM-style RTTI: The argument type of `classof()` should be a strict ancestor.

| | | | | | | | | | | | | | | TinyPtrVector. With these, it is sufficiently functional for my more normal / pedestrian uses. I've not included some r-value reference stuff here because the value type for a TinyPtrVector is, necessarily, just a pointer. I've added tests that cover the basic behavior of these routines, but they aren't as comprehensive as I'd like. In particular, they don't really test the iterator semantics as thoroughly as they should.

* Bring TinyPtrVector under test. Somehow we never picked up unit testsChandler Carruth2012-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | for this class. These tests exercise most of the basic properties, but the API for TinyPtrVector is very strange currently. My plan is to start fleshing out the API to match that of SmallVector, but I wanted a test for what is there first. Sadly, it doesn't look reasonable to just re-use the SmallVector tests, as this container can only ever store pointers, and much of the SmallVector testing is to get construction and destruction right. Just to get this basic test working, I had to add value_type to the interface. While here I found a subtle bug in the combination of 'erase', 'begin', and 'end'. Both 'begin' and 'end' wanted to use a null pointer to indicate the "end" iterator of an empty vector, regardless of whether there is actually a vector allocated or the pointer union is null. Everything else was fine with this except for erase. If you erase the last element of a vector after it has held more than one element, we return the end iterator of the underlying SmallVector which need not be a null pointer. Instead, simply use the pointer, and poniter + size() begin/end definitions in the tiny case, and delegate to the inner vector whenever it is present. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161024 91177308-0d34-0410-b5e6-96231b3b80d8

These appear to be essentially untested in the unit tests until now. Fix several tests to be robust in the face of a '0' small buffer. As a consequence of this size buffer, the growth patterns are actually observable in the test -- yes this means that many tests never caused a grow to occur before. For some tests I've merely added a reserve call to normalize behavior. For others, the growth is actually interesting, and so I captured the fact that growth would occur and adjusted the assertions to not assume how rapidly growth occured. Also update the specialization for a '0' small buffer length to have all the same interface points as the normal small vector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161001 91177308-0d34-0410-b5e6-96231b3b80d8
