2.7.2.3 Signal Array

The signal array appears somewhat further down the stack. This array comprises all longwords so that the structure is VAX compatible. A signal array describes the exception that occurred. It contains an argument count, the exception code, zero or more exception parameters, the PC, and the PS. Therefore, the size of a signal array can vary from exception to exception. Although there are several possible exception conditions, access violations are most common. Figure 2-3 shows the signal array for an access violation.

Figure 2-3 Signal Array

For access violations, the signal array is set up as follows:

Value Meaning

Vector list length Number of longwords that follow. For access violations, this value is always 5.

Condition value Exception code. The value 0C ₁₆ represents an access violation. You can identify the exception code by using the SDA command EVALUATE/CONDITION_VALUE or SHOW CRASH.

Additional arguments These can include a reason mask and a virtual address.
In the longword mask if bit 0 of the longword is set, the failing instruction (at the PC saved below) caused a length violation. If bit 1 is set, it referred to a location whose page table entry is in a "no access" page. Bit 2 indicates the type of access used by the failing instruction: it is set for write and modify operations and clear for read operations.
The virtual address represents the low-order 32 bits of the virtual address that the failing instruction tried to reference.

PC PC whose execution resulted in the exception.

PS PS at the time of the exception.

Value	Meaning
Vector list length	Number of longwords that follow. For access violations, this value is always 5.
Condition value	Exception code. The value 0C ₁₆ represents an access violation. You can identify the exception code by using the SDA command EVALUATE/CONDITION_VALUE or SHOW CRASH.
Additional arguments	These can include a reason mask and a virtual address. In the longword mask if bit 0 of the longword is set, the failing instruction (at the PC saved below) caused a length violation. If bit 1 is set, it referred to a location whose page table entry is in a "no access" page. Bit 2 indicates the type of access used by the failing instruction: it is set for write and modify operations and clear for read operations. The virtual address represents the low-order 32 bits of the virtual address that the failing instruction tried to reference.
PC	PC whose execution resulted in the exception.
PS	PS at the time of the exception.

2.7.2.4 64-Bit Signal Array

The 64-bit signal array also appears further down the stack. This array comprises all quadwords and is not VAX compatible. It contains the same data as the signal array, and Figure 2-4 shows the 64-bit signal array for an access violation. The SDA SHOW STACK command uses the CHF64$ symbols listed in the figure to identify the 64-bit signal array on the stack.

Figure 2-4 64-Bit Signal Array

For access violations, the 64-bit signal array is set up as follows:

Value Meaning

Vector list length Number of quadwords that follow. For access violations, this value is always 5.

Condition value Exception code. The value 0C ₁₆ represents an access violation. You can identify the exception code by using the SDA command EVALUATE/CONDITION_VALUE or SHOW CRASH.

Additional arguments These can include a reason mask and a virtual address.
In the quadword mask if bit 0 of the quadword is set, the failing instruction (at the PC saved below) caused a length violation. If bit 1 is set, it referred to a location whose page table entry is in a "no access" page. Bit 2 indicates the type of access used by the failing instruction: it is set for write and modify operations and clear for read operations.

PC PC whose execution resulted in the exception.

PS PS at the time of the exception.

Value	Meaning

PS	PS at the time of the exception.

2.7.2.5 Alpha Exception Stack Frame

Figure 2-5 illustrates the Alpha exception stack frame, which comprises all quadwords.

The values contained in the exception stack frame are defined as follows:

2.7.2.7 SSRVEXCEPT Example

If OpenVMS encounters a fatal exception, you can find the code that signaled it by examining the PC in the signal array. Use the SHOW CRASH or CLUE CRASH command to display the PC and the instruction stream around the PC to locate the exception.

The following display shows the SDA output in response to the SHOW CRASH and SHOW STACK commands for an Alpha SSRVEXCEPT bugcheck. It illustrates the mechanism array, signal arrays, and the exception stack frame previously described.
