6ef76a92f4 [AST] Use flat array storage for SubstitutionMap's replacement types. 
The replacement types in a SubstitutionMap correspond with the generic
parameters of its generic signature, so replace the DenseMap storage
with a flat array of Types, one element for each generic parameter.

42c59554a0 Introduce the Space Engine 
Implement exhaustiveness checking in Sema with rich error messages.  The
algorithm used is a variant of the one described in Fengyun Liu's paper
"A Generic Algorithm for Checking Exhaustivity of Pattern Matching"
published in the EPFL conference, and Luc Maranget's seminal paper
"Warnings for Pattern Matching"

The Space Engine views pattern matching as a problem of projecting the
scrutinee of a pattern-match into a "Space", then iteratively
constructing a Space from the cases.  Taking the difference of this
master space and the covered spaces yields the "holes" left over or
reveals a completely covered space.

The algorithm also extends trivially to redundancy checks in patterns,
but that check is already implemented in SILGen and this algorithm does
not improve upon it.

1168cacf4f [Serialization] Drop decls whose types can't be deserialized. 
Proof-of-concept for the above. This shouldn't be common---renames are
far more likely, and those we can track---but occurs when the
swift_wrapper attribute (the implementation of NS_STRING_ENUM) is
active in Swift 4 but not in Swift 3.

Note that this only checks the canonical interface type of the
declaration, because the non-canonical type may contain references to
the declaration's generic parameters.

[Migrator] Make remap file an additional output
 2017-04-27 01:40:26 -07:00
David Farler
63776b507b When converting some of the old Migrator automation to the new Migrator, 
I had set up the driver to invoke a separate frontend invocation with
the "update code" mode. We sort of did this last release, except we
forked to the swift-update binary instead. This is causing problems with
testing in Xcode.

Instead, let's perform a single compile and add the remap file as an
additional output during normal compiles. The driver, seeing
-update-code, will add -emit-remap-file-path $PATH to the -c frontend
invocation.
