Andrew Kelley 84e952c230 fix await multithreaded data race
coro return was reading from a value that coro await was
writing to. that wasn't how it was designed to work, it
was an implementation mistake.

this commit also has some work-in-progress code for fixing
error return traces across suspend points.

Andrew Kelley 026aebf2ea another workaround for llvm coroutines
this one doesn't work either
2018-02-28 04:01:22 -05:00
Andrew Kelley 556f22a751 different way of fixing previous commit
get_fn_type doesn't need the complete parameter type, it
can just ensure zero bits known.

Ben Noordhuis 90598b4631 fix assert on self-referencing function ptr field
The construct `struct S { f: fn(S) void }` is not legal because structs
are not copyable but it should not result in an ICE.

Fixes #795.

Andrew Kelley 6e2a67724c Revert "another llvm workaround for getelementptr"
This reverts commit c2f5634fb3.

It doesn't work. With this, LLVM moves the allocate fn call
to after llvm.coro.begin

Andrew Kelley 4ac6c4d6bf workaround llvm coro transformations
by making alloc and free functions be parameters to async
functions instead of using getelementptr in the DynAlloc block

Andrew Kelley 40dbcd09da fix type_is_codegen_pointer being used incorrectly
The names of these functions should probably change, but at least
the semantics are correct now:
 * type_is_codegen_pointer - the type is either a fn, ptr, or promise
 * get_codegen_ptr_type -
   - ?&T and &T returns &T
   - ?promise and promise returns promise
   - ?fn()void and fn()void returns fn()void
   - otherwise returns nullptr
