  • Publication number: 20150199258
    Abstract: A method, computer program product, and computer system for setting, at a computing device, a breakpoint of a plurality of breakpoints for use by a debugger at an entry point of a plurality of entry points for a component of a plurality of components, wherein the breakpoint is set automatically. While executing the debugger on the component, it is determined whether the breakpoint is reached from outside of the component by a program. If the breakpoint is reached from outside of the component, the program executed by the debugger stops. If the breakpoint is reached from inside of the component, the program executed by the debugger continues.

  • Publication number: 20150197687
    Abstract: A sandwich structure for enhancement of photoluminescence (PL) from luminescent films and the corresponding preparation method are disclosed. The sandwich structure comprises a support, a luminescent film grown on the support, and a close-packed dielectric microsphere monolayer deposited onto the luminescent film. The microspheres have high transmittance excitation light and emitted light, respectively. The low price of dielectric microspheres is beneficial to industrial applications. The stable chemical properties of dielectric microspheres make PL enhanced in a long term. Both metal and non-metal materials can be used as the support in the sandwich structure. These features significantly improve the technique of PL enhancement for luminescent films.

  • Patent number: 8959502
    Abstract: The present disclosure provides a method and system for processing table of content (TOC) access overflow in an application. The method may determine whether there occurs a TOC access overflow within an object file during linking the object file that may be generated from the compiling. If the TOC access overflow occurs within the object file, then the source file corresponding to the object file may be re-compiled so as to generate an object file having no TOC access overflow, and the object file may be re-linked to generate an executable file of the application. The present disclosure may adopt two-pass compiling and a dual-instruction TOC access in a form of two pieces of instructions that may be generated for TOC entries within which TOC overflows generally occur.

  • Publication number: 20140289707
    Abstract: An optimized version of a binary and a non-optimized debuggable version of a binary for each compiling unit in the source code program are generated. The optimized versions of binaries of all compiling units are loaded into memory for debugging, which is monitored. In response to determining that a first compiling unit in the source code program is to be debugged, the non-optimized debuggable version of the binary is loaded into a memory location that was previously used by the optimized version of the binary. In response to determining that debugging of a second compiling unit in the source code program is to be cancelled, the optimized version of the binary of the second compiling unit is loaded into a memory location that was previously used by the non-optimized debuggable version of the binary.

  • Publication number: 20140208301
    Abstract: The present invention discloses a method and apparatus for function calling that eliminates or reduces errors caused by calling convention mismatch by preparing a number of candidate code modules during program compiling and inserting them in a compiled program. A library of compiled candidate code modules is thus included in the complied program, which allows the user to call a function by specifying a function to be called and a library where it belongs in the source program, without need to know the calling convention thereof or to focus on the call execution process. This ensures the matching of calling convention between the caller and callee of the function while being transparent to users, so as to avoid problems caused by calling convention inconsistency.
