Code Compaction optimizations: Optimizations strategies for code compaction that are spec'ed out. a) Loop Rereolling in straight line code. In this optimization isomorphic operation ...
Four live ranges L1/L2/L3/L4. Live range L1 for variable ‘a’ spans the loop but has no references ‘a’ inside the Loop. similarly, live range L2 for variable ‘b’ spans the loop but has no references ...
Live range splitting at each use points increases the number of live ranges that could be performance bottleneck. Split partner ranges could be assigned different registers increasing more copies. Increase ...
Unaligned memory access in vectorization For misaligned array access inside the loops for aligned architecture, vectorization is done with respect to shifting after loading the memory aligned and ...
Register Allocation on SSA Graphs. The SSA graph has the property that def dominates uses. This makes the SSA graph strict. Due to this property the live range is the subset of dominator tree. The ...
Live range splitting optimization. There is an important concept above the Live range splitting. If the interference graph is not colorable then the allocator goes for Live range splitting, and ...
Static Single Assignment. Each definition has a different version and the def dominates the uses. Such representation of SSA is strict and conventional. The non-conventional SSA is the representation ...
Register Allocation Chaitin’s and Brigg’s register allocator has different phases. Renumber: I dentification of Live ranges: Live ranges identification is the backward ...

Avoiding SQL injections in ILE-RPG with embedded SQL (SQLRPGLE) Dynamic embedded SQL is a great tool, if you have to create your SQL statements depending on user input. But "inserting" those user inputs ...
IBM i APIs can look a bit complicated - even more the Crypto API suite, as you have to deal with "algorithms", "context tokens", "crypto providers" and more. So I'd like to guide you through a small ...
🚀 Exciting News for Developers! .NET 9.0 Now Available on IBM Power with Red Hat Enterprise Linux and OpenShift 🖥️ Just demonstrated the seamless installation of .NET 9.0 on IBM Power ppc64le ...
I am thrilled to announce the general availability of IBM Open XL C/C++ for AIX 17.1.3 and IBM Open XL Fortran for AIX 17.1.3 , officially launched on November 15, 2024. The IBM Open ...
If your application needs multithreading, the POSIX API for multithreading – called pthreads – is the classic way, to run multiple procedures parallel at the same time and in the same process. Using ...
