Abstract
A computer implemented method, a computer program product, and a data processing system trace information about current context and system state for either 32-bit or 64-bit applications. A 32-bit trace executable code and a 64-bit trace executable code are compiled for a trace script. A determination is then made as to whether an application process is a 32-bit process or a 64-bit process. Responsive to determining that the application process is the 32-bit process or the 64-bit process, an internal indicator is set to indicate the application process as either a 32-bit process or a 64-bit process. Subsequently, the internal indicator is identified as either indicating the 32-bit process or the 64-bit process. If the internal identifier indicates the application process is a 32-bit process, an instruction pointer is set to indicate the 32-bit trace executable code, and the 32-bit trace executable code is executed. If the internal identifier indicates the application process is a 64-bit process, an instruction pointer is set to indicate the 64-bit trace executable code, and the 64-bit trace executable code is executed.
