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...
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 ...
If we introduce multiple branch prediction =-=[1]-=-[16], then the fetch unit can at least fetch multiple contiguous basic blocks in a cycle. Data for the number of instructions between taken branches shows that the upper bound on fetch bandwidth is st......
As soon as I noticed that a few blocks I had added were very similar to each other, and furthermore, each block required referring to the same variable three times, the DRY bell went off in my head, and I set out to find the right way to do what I was trying to do with this ...

After the preprocessor finds out basic blocks, bytecode-to-C translation is preformed for each basic block. The generated C codes for all basic blocks in a Java method are wrapped up in a switch statement like Toba [8]. The switch statement is used to handle Java exceptions. Some ...
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 ...
Basic-Block reordering is a kind of compiler optimization technique which has the effect of reducing branch penalty and I-cache miss cost by reordering basic blocks in memory. 基本块重排是一类通过重新排布基本块在存储中的位置,以减少转移开销和指令cache失效率的编译优化技术。 3. Based on loop-carr...
