Previously we were linking in all SIL entities
if the input was a serialized non-SIB AST, and
`-disable-sil-linking` wasn't specified. However
none of the tests appear to want this behaviour.
Stop calling `SerializedSILLoader::getAll`, and
remove the `-disable-sil-linking` option, as this
is now the default behaviour.
What these tests are testing has nothing to do with whether or not we
deserialize anything from the standard library, and not doing so saves
more than two minutes (single-threaded) on my machine from each test.
LLDB changes accessiblity of declarations after type checking,
which is not a good idea because it is likely to break invariants.
Indeed, the validateFixedLayoutAttribute() / hasFixedLayout()
logic was not prepared for this possibility.
This is a targeted fix to address the immediate breakage. A better
fix would be to change LLDB, and also to change Sema to store the
global -enable-resilience flag state in a bit in the serialized
module, instead of sticking it on every declaration.
Fixes <rdar://problem/23545959>.
This is an internal-only affordance for the numerics team to be able to work on SIMD-compatible types. For now, it can only increase alignment of fixed-layout structs and enums; dynamic layout, classes, and other obvious extensions are left to another day when we can design a proper layout control design.
