A method for a fault free store data path in a software implementation of redundant multithreading environments is described. In one embodiment, after a check is performed by a hardware/software checker, the processor still needs to ensure that the data just checked reaches protected memory without any faults. The present implementation provides sufficient redundant information along the path of a store from register read to commit, such that it may detect any single bit upset error in the path.

Executable code is modified to include prefetch instructions for certain loads. The targeted loads preferably include those loads for which a compiler cannot compute a stride (which represents the difference in memory addresses used in consecutive executions of a given load). Whether prefetch instructions should be included for such loads is determined preferably by running the code with a training data set which determines the frequency of strides for each subsequent execution of a load. If a stride occurs more than once for a load, then that load is prefetched by inserting a prefetch instruction into the executable code for that load. Further, a stride value is associated with the inserted prefetch. Preferably, the stride value is the most frequently occurring stride, which can be determined based on the results of the training data set. Alternatively, the stride can be computed during run-time by the code itself.

In one embodiment, the present invention includes a method for receiving a command to insert instrumentation code into a code segment, analyzing the code segment to determine an optimal location for the instrumentation code within the code segment, and inserting the instrumentation code at the optimal location to generate an instrumented code segment. The instrumented code segment may then be executed and may provide for improved performance over unoptimized instrumented code. Other embodiments are described and claimed.

Methods and apparatus to inline conditional software instrumentation are disclosed. An example method comprises splitting a software instrumentation conditional analysis procedure for an application segment into an unconditional portion and a conditional portion, and inlining the unconditional portion.

A profile feedback optimization system is provided. The system accepts as input an original application and produces an optimized version of the application. The system first instruments the original application through an instrumentation process such that when it executes, it generates profile data. During instrumentation, the system configures images in the application to trap any function calls to critical functions. This allows the instrumented version of the application to execute transparently and appear as the original version. The instrumentation process converts each original image of the application to a version that references other instrumented images. The instrumentation process also configures the operating system to execute the instrumented version instead of the original version when the user selects the application for execution. Once instrumented, the instrumented application is executed. During execution, profile data produced from the instrumented images is saved in a database.

A dental X-ray aiming device adapted to place an X-ray film packet having sharp edges at a proper position in the oral cavity of a patient. The device includes a packet holder that serves to shield the sharp edges of the packet to avoid direct contact with tissue within the oral cavity and the resultant discomfort, pain or trauma. The holder is formed by a rectangular frame of resilient plastic material within which the packet is socketed, and a bite block joined to the front of the frame which, when clenched between the teeth of the patient, then places the held film packet behind a tooth region to be examined. The device also includes a distance-calibrated guide rod which is detachably coupled to the bite block, and a sighting ring adapted to receive the nose cone of an X-ray unit, the ring being slidable along the rod to a desired position thereon, whereby an X-ray beam is projected from the nose cone in accurate relationship to the film packet.

A method for permitting software optimization tools, software instrumenting tools and other analysis tools to re-write executables having mixed instructions and data uses a data structure having an entry for each multi-bit word in an executable file. Each entry of the data structure includes a number of flags that are set to identify the type of the multi-bit word in the associated line of the executable file. The types include instruction, data and unclassified. Each entry also includes a flag that indicates that the multi-bit word should not be optimized and a flag indicating that the multi-bit word is a problem branch. The no-optimize and problem branch flags may be used to identify multi-bit words that may be either branch instructions or data, and to ensure that such multi-bit words are not affected by optimization or other rewriting of the executable. In addition, a problem fall through flag is provided to maintain program flow for possible fall through code segments.

Apparatus is provided for forming a foreign language file from a native language file so that the display for a given equipment can be rendered in the foreign language rather than the native language. The apparatus is comprised of a native language file containing instructions for the format of the display, words to be translated, and contextual information related to the latter words, a translation tool for reading the native language file and forming an image of the native words to be translated, the size and shape of the space allotted to them and a blank space into which equivalent foreign words can be inserted, means for inserting the foreign words, and means for storing in a file the foreign words and the instructions for the format to be used.
