Furthermore, sincecompiler optimizationpasses are oblivious to protections implemented, they could potentially break them and thus cause false alarms in protected programs. For instance, some compilers utilize enhanced memory caching by block reordering. This relocates program blocks after protection is laid...
overlapped redundancies of basic blocksDynamic binary translation technology always chooses basic block as the unit of translation and execution. Different from static binary translation, the basic blocks to be translated in dynamic binary translation may have the same instructions as the other ones ...

This paper presents Codestitcher, an inter-procedural basic block code layout optimizer which reorders basic blocks in an executable to benefit from better cache and TLB performance. Codestitcher provides a hierarchical framework which can be used to improve locality in various layers of the memory ...
One of the most important and complex parts of any modern compiler. A very active area of research. There is a whole class (CS243) dedicated to this material. Sources of Optimization In order to optimize our IR, we need to understand why it can be improved in the first place. ...
Outside of profile-guided optimization, the JIT has traditionally been conservative about rearranging the basic blocks of methods it compiles, leaving them in MSIL order except to segregate code it identifies as “rarely-run” (e.g. blocks that throw or catch exceptions). Of course, MSIL order...
A function won’t be instrumented by any probe if it only has one basic block (a sequence of instructions with one entry and exit). In fact, it might be inlined in spite of the /Ob0 switch. Besides the value probe, every switch statement causes the ...
Basic Blocks Source codes generally have a number of instructions, which are always executed in sequence and are considered as the basic blocks of the code. These basic blocks do not have any jump statements among them, i.e., when the first instruction is executed, all the instructions in ...
Each matrix is stored in block-row-major with blocks (called panels) of fixed height, and within each panel the matrix elements are stored in column-major. Tests BLASFEO provides some functionality to test the correctness of its linear algebra routines, for both the BLASFEO and the BLAS ...
