Abstract
Official abstract text for this publication.
A method ( 500 ) or a diagnostic recording device ( 400 ) having transactional memory and a processor coupled to the transactional memory can store ( 502 ) contents of a transaction log ( 40 ) of the transactional memory, detect ( 504 ) an exception event, and replay ( 506 ) last instructions that led up to the exception event using a debugger tool ( 80 ). The transactional memory can be hardware or software based transactional memory. The processor can also store the transaction log by storing the contents of the transaction log in a core file ( 302 ) which can include a stack ( 60 ), a register dump ( 70 ), a memory dump ( 75 ), and the transactional log. The debugger tool can be used to load up the core file, an executable file ( 95 ), and a library ( 90 ) to enable the diagnostic recording device to retrace transactions occurring at the diagnostic recording device up to the exception event.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of gathering diagnostic information in a hardware-based transactional memory system, comprising: responsive to detecting an exception event has occurred in a first thread, invoking a system call of an operating system to access a portion, of a transaction log of a hardware-based transactional memory, that corresponds to the first thread, wherein the transaction log is stored in a hardware buffer of the hardware-based transactional memory, wherein th…
