Local vars, marked with pragma allocate, mustbe allocate by the call of
the runtime function and cannot be allocated as other local variables.
Instead, we allocate a space for the pointer in private record and store
the address, returned by kmpc_alloc call in this pointer.
So, for untied tasks
```
#pragma omp task untied
{
S s;
#pragma omp allocate(s) allocator(allocator)
s = x;
}
```
compiler generates something like this:
```
struct task_with_privates {
S *ptr;
};
void entry(task_with_privates *p) {
S *s = p->s;
switch(partid) {
case 1:
p->s = (S*)kmpc_alloc();
kmpc_omp_task();
br exit;
case 2:
*s = x;
kmpc_omp_task();
br exit;
case 2:
~S(s);
kmpc_free((void*)s);
br exit;
}
exit:
}
```

//===----------------------------------------------------------------------===// // C Language Family Front-end //===----------------------------------------------------------------------===// Welcome to Clang. This is a compiler front-end for the C family of languages (C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM compiler infrastructure project. Unlike many other compiler frontends, Clang is useful for a number of things beyond just compiling code: we intend for Clang to be host to a number of different source-level tools. One example of this is the Clang Static Analyzer. If you're interested in more (including how to build Clang) it is best to read the relevant web sites. Here are some pointers: Information on Clang: http://clang.llvm.org/ Building and using Clang: http://clang.llvm.org/get_started.html Clang Static Analyzer: http://clang-analyzer.llvm.org/ Information on the LLVM project: http://llvm.org/ If you have questions or comments about Clang, a great place to discuss them is on the Clang development mailing list: http://lists.llvm.org/mailman/listinfo/cfe-dev If you find a bug in Clang, please file it in the LLVM bug tracker: http://llvm.org/bugs/
