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>Stack Coloring - We have implemented a new optimization pass + to merge stack objects which are used in disjoin areas of the code. + This optimization reduces the required stack space significantly, in cases + where it is clear to the optimizer that the stack slot is not shared. + We use the lifetime markers to tell the codegen that a certain alloca + is used within a region.</p> <p>We have put a significant amount of work into the code generator infrastructure, which allows us to implement more aggressive algorithms and |
