  • Patent number: 11966726
    Abstract: A method, computer program product, and computer system are provided. An enhanced compiler identifies instructions for execution among them, instructions directed to an inner computation unit of a CPU core. In response to identifying instructions directed to the inner computation unit, locating in a system call table a system call to indicate a begin of an executable code block of instructions that are directed to the inner computation unit of the CPU core. The enhanced compiler searches the system hardware registry for the parameter corresponding to the inner computation unit of the CPU core. The system call is inserted as an interrupt instruction in the compiler output at the begin of the executable code block of instructions that are directed to the inner computation unit of the CPU core. The enhanced compiler executable code output is saved for later selection by a scheduler of an operating system.

  • Publication number: 20240020112
    Abstract: Managing source code change set commits to decrease time to identify software bugs in versions of a software project is provided. An initial order of relevant commits corresponding to the software project is determined in a priority queue based on a weight of each respective commit of the relevant commits. The initial order of the relevant commits is adjusted in the priority queue based on a build distance between the relevant commits of affected source files. A particular commit having a highest priority ranking is selected in the priority queue for build and test. The build and the test of the particular commit having the highest priority ranking in the priority queue is executed.

  • Patent number: 11615014
    Abstract: Provided are techniques for using relocatable debugging information entries to save compile time when there are changes to source code. While compiling source code, for an unchanged function, a copy is made of a relocatable debugging information entries table and of a relocation information table. In addition, for a changed function, a new relocatable debugging information entries table and a new relocation information table are generated. The copy of the relocatable debugging information entries table and the new relocatable debugging information entries table are merged. The copy of the relocation information table and the new relocation information table are merged. The relocatable debugging information entries in the merged relocatable debugging information entries table are resolved according to information in the merged relocation information table to generate relocated Debugging with Attributed Record Formats information, which is stored in an object file that corresponds to the source code.
