* Add range erase, element insert, and range insert methods toChandler Carruth2012-08-01
| | | | | | | | | | | | | | | 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. Maybe some brave soul will feel enterprising and flesh them out. ;] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161104 91177308-0d34-0410-b5e6-96231b3b80d8

* 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
* Move the SmallVector unit tests to be type-parameterized so that we canChandler Carruth2012-07-30
| | | | | | | | | | | | | | | | | | | | test more than a single instantiation of SmallVector. Add testing for 0, 1, 2, and 4 element sized "small" buffers. 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

| | | | | | | | | Added a basic unit test for this with CreateCondBr. I didn't go all the way and test the switch side as the boilerplate for setting up the switch IRBuilder unit tests is a lot more.

| | | | | | | | | | | | | | | | | This was always part of the VMCore library out of necessity -- it deals entirely in the IR. The .cpp file in fact was already part of the VMCore library.

* Completely refactor the structuring of unittest CMake files to match theChandler Carruth2012-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Makefiles, the CMake files in every other part of the LLVM tree, and sanity. This should also restore the output tree structure of all the unit tests, sorry for breaking that, and thanks for letting me know. The fundamental change is to put a CMakeLists.txt file in the unittest directory, with a single test binary produced from it. This has several advantages: - No more weird directory stripping in the unittest macro, allowing it to be used more readily in other projects. - No more directory prefixes on all the source files. - Allows correct and precise use of LLVM's per-directory dependency system. - Allows use of the checking logic for source files that have not been added to the CMake build. This uncovered a file being skipped with CMake in LLVM and one in Clang's unit tests. - Makes Specifying conditional compilation or other custom logic for JIT tests easier. It did require adding the concept of an explicit 'optional' source file to the CMake build so that the missing-file check can skip cases where the file is *supposed* to be missing. =] This is another chunk of refactoring the CMake build in order to make it usable for other clients like CompilerRT / ASan / TSan. Note that this is interdependent with a Clang CMake change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158909 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix PR13148, an inf-loop in StringMap.Chandler Carruth2012-06-19
| | | | | | | | | | | | | | | StringMap suffered from the same bug as DenseMap: when you explicitly construct it with a small number of buckets, you can arrange for the tombstone-based growth path to be followed when the number of buckets was less than '8'. In that case, even with a full map, it would compare '0' as not less than '0', and refuse to grow the table, leading to inf-loops trying to find an empty bucket on the next insertion. The fix is very simple: use '<=' as the comparison. The same fix was applied to DenseMap as well during its recent refactoring.
