The problem is that we might invalidate a later slice by vectorizing a former slice. Use a WeakVH to track the pointer. If the pointer is deleted or RAUW'ed we can tell. The test case will only fail when running with libgmalloc. radar://15498655 ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_34@195222 91177308-0d34-0410-b5e6-96231b3b80d8

This was found by a perniciously unstable sort implementation used to flush out buggy uses of the algorithm. The fundamental idea is that findCommonType should return the best common type it can find across all of the slices in the range. There were two bugs here previously: 1) We would accept an integer type smaller than a byte-width multiple, and if there were different bit-width integer types, we would accept the first one. This caused an actual failure in the testcase updated here when the sort order changed. 2) If we found a bad combination of types or a non-load, non-store use before an integer typed load or store we would bail, but if we found the integere typed load or store, we would use it. The correct behavior is to always use an integer typed operation which covers the partition if one exists. While a clever debugging sort algorithm found problem #1 in our existing test cases, I have no useful test case ideas for #2. I spotted in by inspection when looking at this code. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_34@195217 91177308-0d34-0410-b5e6-96231b3b80d8

Extend the type to prevent most of those cases. The problem is loops like: int main () { int a = 1; char b = 0; lbl: a &= 4; b--; if (b) goto lbl; return a; } The backedge count is 255. The induction variable type is i8. If we add one to 255 to get the exit count we overflow to zero. To work around this issue we extend the type of the induction variable to i32 in the case of i8 and i16.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change is incorrect. If you delete virtual destructor of both a base class and a subclass, then the following code: Base *foo = new Child(); delete foo; will not cause the destructor for members of Child class. As a result, I observe plently of memory leaks. Notable examples I investigated are: ObjectBuffer and ObjectBufferStream, AttributeImpl and StringSAttributeImpl. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194997 91177308-0d34-0410-b5e6-96231b3b80d8
