<p>We have changed the way that the Type Legalizer legalizes vectors. The type
|
||||
legalizer now attempts to promote integer elements. This enabled the
|
||||
implementation of vector-select. Additionally, we see a performance boost on
|
||||
workloads which use vectors of chars and shorts, since they are now promoted
|
||||
to 32-bit types, which are better supported by the SIMD instruction set.
|
||||
Floating point types are still widened as before.</p>
|
||||
|
||||
|
||||
<p>We have put a significant amount of work into the code generator
|
||||
infrastructure, which allows us to implement more aggressive algorithms and
|
||||
make it run faster:</p>
