ParseCompileUnit is normally called very early on (and with the right
symbol file object) during the process of accessing a compile unit.
The only way this can be triggered is if the DWARF unit is

reverted.)

Introduce op trait PolyhedralScope for ops to define a new scope for
polyhedral optimization / affine dialect purposes, thus generalizing
such scopes beyond FuncOp. Ops to which this trait is attached will
define a new scope for the consideration of SSA values as valid symbols
for the purposes of polyhedral analysis and optimization. Update methods

[analyzer] Track runtime types represented by Obj-C Class objects

Summary:
Objective-C Class objects can be used to do a dynamic dispatch on
class methods. The analyzer had a few places where we tried to overcome
the dynamic nature of it and still guess the actual function that
is being called. That was done mostly using some simple heuristics
covering the most widespread cases (e.g. [[self class] classmethod]).
This solution introduces a way to track types represented by Class
objects and work with that instead of direct AST matching.

4 years ago[AST] Use PrintingPolicy for format string diagnosis

[AST] Use PrintingPolicy for format string diagnosis

Summary:
This is a small improvement for OpenCL diagnostics, but is also useful
for our CHERI fork, as our __capability qualifier is suppressed from
diagnostics when all pointers are capabilities, only being used when pointers
need to be explicitly opted-in to being capabilities.
