conditional-execution

Naively, conditionally executed instructions seem like a great idea to me. As I read more about ARM (and ARM-like) instruction sets (Thumb2, Unicore, AArch64) I find that they all lack the bits for conditional execution. Why is conditional execution missing from each of these? Was conditional execution a mistake at the time, or have subsequent changes made it an expensive waste of instruction bits? auselen General claim is modern systems have better branch predictors and compilers are much more advanced so their cost on instruction encoding space is not justified. This is from ARMv8

Is there a way to perform conditional execution of snippet in pom.xml? my requirement is to copy a file/directory to deploy structure based on variable defined in pom.xml... eg: < if > < equals arg1="package" arg2="package"/> < then> .... < /then> < /if> Not sure how can I achieve this! Any pointers would be highly appreciated. Thanks, SR Probably you'll need to use Maven AntRun Plugin for that. In general, there's no conditional expressions in POM. The only thing similar somehow to this are build profiles that can be activated on some specified conditions, however they probably don't fit into

Is there a way to determine if the loop is iterating for the last time. My code looks something like this: int[] array = {1, 2, 3...}; StringBuilder builder = new StringBuilder(); for(int i : array) { builder.append("" + i); if(!lastiteration) builder.append(","); } Now the thing is I don't want to append the comma in the last iteration. Now is there a way to determine if it is the last iteration or am I stuck with the for loop or using an external counter to keep track. Another alternative is to append the comma before you append i, just not on the first iteration. (Please don't use "" + i ,
