132e604aa3 llvm coroutine workaround: sret functions return sret pointer 2018-02-27 17:12:53 -05:00

6e2a67724c Revert "another llvm workaround for getelementptr" 
This reverts commit c2f5634fb3df51622cf74f23b4ae0d4a7d2bbbe9.

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

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

6fece14cfb self-hosted: build against zig_llvm and embedded LLD 
Now the self-hosted compiler re-uses the same C++ code for interfacing
with LLVM as the C++ code.
It also links against the same LLD library files.

2a25398c86 fix segfault when passing union enum with sub byte... 
...field to const slice parameter

we use a packed struct internally to represent a const array
of disparate union values, and needed to update the internal
getelementptr instruction to recognize that.
