  • Efficient garbage collection and exception handling in a hardware accelerated transactional memory system
    Patent number: 9658880
    Abstract: Handling garbage collection and exceptions in hardware assisted transactions. Embodiments are practiced in a computing environment including a hardware assisted transaction system. A method includes beginning a hardware assisted transaction, raising an exception while in the hardware assisted transaction, including creating an exception object, determining that the transaction should be rolled back, and as a result of determining that the transaction should be rolled back, marshaling the exception object out of the hardware assisted transaction.

  • Efficient garbage collection and exception handling in a hardware accelerated transactional memory system
    Patent number: 8402218
    Abstract: Handling garbage collection and exceptions in hardware assisted transactions. Embodiments are practiced in a computing environment including a hardware assisted transaction system. Embodiments includes acts for writing to a card table outside of a transaction; handling garbage collection compaction occurring when a hardware transaction is active by using a common global variable and instructing one or more agents to write to the common global variable any time an operation is performed which may change an object's virtual address; acts for managing a thread-local allocation context; acts for handling exceptions while in a hardware assisted transaction.

  • Hardware accelerated transactional memory system with open nested transactions
    Patent number: 8229907
    Abstract: Hardware assisted transactional memory system with open nested transactions. Embodiments include a system whereby hardware acceleration of transactions can be accomplished by implementing open nested transaction in hardware which respect software locks such that a top level transaction can be implemented in software, and thus not be limited by hardware constraints typical when using hardware transactional memory systems.

  • System and method for virtual catching of an exception
    Publication number: 20060101411
    Abstract: The techniques and mechanisms described herein are directed to a method for virtually catching an exception. A debugger receives a notification identifying information about an exception that occurred during execution of an application. The debugger then selectively chooses a location on a call stack where execution of the application resumes after the stack is unwound up to the selected location. The location being between a statement on the stack causing the exception and a handler on the stack. The handler being identified during a search phase for exception processing. The mechanism being operative for both handled exceptions and unhandled exceptions.

  • Method and system for program editing
    Publication number: 20050034109
    Abstract: A system and method of providing edit and continue support in a software program debugging environment. “Edit and continue” support allows a user (e.g., programmer and/or developer) to update the code and/or data structure(s) of an executing program while it is running. After the user has finished editing their code and resumes execution, an integrated development environment (IDE) propagates the edit(s) into a common language runtime (CLR) environment before continuing. Therefore, from the CLR environment's perspective, an edit is a block of intermediate language code (IL) and/or metadata that is inserted into a running process. The IDE can facilitate: determining “legality” of an edit; building the edit; sending the edit to the CLR environment; and/or, facilitating the CLR environment switch execution to the edited code.

  • Method and system for program editing
    Publication number: 20050028137
    Abstract: A method and system are disclosed for editing a software program in a common language runtime environment, wherein the software program has a source code component, an intermediate language component, and a native code component. The method comprises executing a first portion of the native code component, suspending execution of the native code component at a first point, and allowing a user to edit the source code component to create an edited source code component. The edited source code component is compiled using a source compiler to create an edited intermediate language component, and the edited intermediate language component is compiled using an intermediate language compiler to create an edited native code component. The edited native code component is then executed beginning at the point where execution was previously suspended.
