Issue ID: 18009
Summary: DMD's backend doesn't produce optimal init code for
smaller types
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P1
Component: dmd
Assignee: [email protected]

An enhancement to DMD's frontend was submitted at
https://github.com/dlang/dmd/pull/2146 for smaller types' init to elicit better
code gen in the backend.
The argument for the code change in the frontend was one of expediency rather
than due diligence.
Some participants in the discussion suggested that such an optimization should
be done in the backend. GDC already optimizes such code in its backend
demonstrating feasibility and establishing precedent.
