RFC: Should SmallVectors be smaller?
...ointer/4B on 32-bit; 2 pointers/16B on 64-bit) if users could afford to test for small-mode vs. large-mode.
The current scheme works out to something like this:
```
template <class T, size_t SmallCapacity>
struct SmallVector {
T *BeginX, *EndX, *CapacityX;
T Small[SmallCapacity];
bool isSmall() const { return BeginX == Small; }
T *begin() { return BeginX; }
T *end() { return EndX; }
size_t size() const { return EndX - BeginX; }
size_t capacity() const { return CapacityX - BeginX; }
};
```
In the past I used something more like:
```

Crash in SmallVector with latest MSVC 2019 (debug mode)
Is anybody using the LLVM/clang/lldb compiled with the MSVC 2019
(x86-32bit) successfully?
I am getting crash in SmallVector at multiple places after a
llvm:SmallVector is being moved around in move constructor or move
operator=.
Not sure what is going on.
~SmallVectorImpl() {
if (!this->isSmall())
free(this->begin()); // <=== crash here, line 336 SmallVector.h
}
The crash occurs only with clang compile in debug mode. Release mode is
fine.

SegFault creating a ExecutionEngine
...gineKind::JIT )
Where module is a `llvm::Module*`. This is code I'm migrating from 3.3
to 3.8. Since the deletion error is happening during constructor I'm at
a bit of a loss as to what I'm doing wrong.

[LLVMdev] Prevent unbounded memory consuption of long lived JIT processes
This series of patches address several issues causing memory usage to grow
indefinetely on a long lived process.
These are not convenional leaks -- memory would have been freed when the LLVM
context or/and JIT engine is destroyed -- but for as long as they aren't the
memory is usage effectively ubounded.
The issues were found using valgrind with '--show-reachable=yes' option:
