ISSUES

------------------------
Known compilation issues
------------------------

- The toolchain compiles to LLVM bitcode with the aarch64 target because all IR
  generated for that target will also correctly codegen for x86-64 (whereas the
  reverse is not true).  However, when compiling using the x86-64 backend clang
  will complain about the aarch64-specific feature "neon"

- Structs/classes whose constituent fields can all be lowered into registers
  are not appropriately split when lowering stackmaps

- OpenMP symbols for outlined functions are known to not align (due to clashing
  symbol names across binaries) but shouldn't cause issues, e.g.,
  ".omp_outlined."

- The compiler doesn't generate transformation metadata to handle fields of
  structs with pointers to the stack

--------------------
Known runtime issues
--------------------

- Functions declared with __attribute__((destructor)) may not work correctly,
  and may cause the application to segfault when exiting
