-/* Most of the fields are self-explanatory. 'sr0' is the next
- instruction to execute, from SRR0, which may have some relationship
- with the instruction that caused the exception. 'r3*' is the value
- that will be returned in register 3 when the current system call
- returns. 'sr1' is SRR1, bits 16-31 of which are copied from the MSR:
-
- 16 - External interrupt enable
- 17 - Privilege level (1=user, 0=supervisor)
- 18 - FP available
- 19 - Machine check enable (if clear, processor locks up on machine check)
- 20 - FP exception mode bit 0 (FP exceptions recoverable)
- 21 - Single-step trace enable
- 22 - Branch trace enable
- 23 - FP exception mode bit 1
- 25 - exception prefix (if set, exceptions are taken from 0xFFFnnnnn,
- otherwise from 0x000nnnnn).
- 26 - Instruction address translation enabled.
- 27 - Data address translation enabled.
- 30 - Exception is recoverable (otherwise, don't try to return).
- 31 - Little-endian mode enable.
-
- 'Trap' is the address of the exception:
-
- 00200 - Machine check exception (memory parity error, for instance)
- 00300 - Data access exception (memory not mapped, see dsisr for why)
- 00400 - Instruction access exception (memory not mapped)
- 00500 - External interrupt
- 00600 - Alignment exception (see dsisr for more information)
- 00700 - Program exception (illegal/trap instruction, FP exception)
- 00800 - FP unavailable (should not be seen by user code)
- 00900 - Decrementer exception (for instance, SIGALRM)
- 00A00 - I/O controller interface exception
- 00C00 - System call exception (for instance, kill(3)).
- 00E00 - FP assist exception (optional FP instructions, etc.)
-
- 'dar' is the memory location, for traps 00300, 00400, 00600, 00A00.
- 'dsisr' has the following bits under trap 00300:
- 0 - direct-store error exception
- 1 - no page table entry for page
- 4 - memory access not permitted
- 5 - trying to access I/O controller space or using lwarx/stwcx on
- non-write-cached memory
- 6 - access was store
- 9 - data access breakpoint hit
- 10 - segment table search failed to find translation (64-bit ppcs only)
- 11 - I/O controller instruction not permitted
- For trap 00400, the same bits are set in SRR1 instead.
- For trap 00600, bits 12-31 of the DSISR set to allow emulation of
- the instruction without actually having to read it from memory.

-/* Most of the fields are self-explanatory. 'sr0' is the next
- instruction to execute, from SRR0, which may have some relationship
- with the instruction that caused the exception. 'r3*' is the value
- that will be returned in register 3 when the current system call
- returns. 'sr1' is SRR1, bits 16-31 of which are copied from the MSR:
-
- 16 - External interrupt enable
- 17 - Privilege level (1=user, 0=supervisor)
- 18 - FP available
- 19 - Machine check enable (if clear, processor locks up on machine check)
- 20 - FP exception mode bit 0 (FP exceptions recoverable)
- 21 - Single-step trace enable
- 22 - Branch trace enable
- 23 - FP exception mode bit 1
- 25 - exception prefix (if set, exceptions are taken from 0xFFFnnnnn,
- otherwise from 0x000nnnnn).
- 26 - Instruction address translation enabled.
- 27 - Data address translation enabled.
- 30 - Exception is recoverable (otherwise, don't try to return).
- 31 - Little-endian mode enable.
-
- 'Trap' is the address of the exception:
-
- 00200 - Machine check exception (memory parity error, for instance)
- 00300 - Data access exception (memory not mapped, see dsisr for why)
- 00400 - Instruction access exception (memory not mapped)
- 00500 - External interrupt
- 00600 - Alignment exception (see dsisr for more information)
- 00700 - Program exception (illegal/trap instruction, FP exception)
- 00800 - FP unavailable (should not be seen by user code)
- 00900 - Decrementer exception (for instance, SIGALRM)
- 00A00 - I/O controller interface exception
- 00C00 - System call exception (for instance, kill(3)).
- 00E00 - FP assist exception (optional FP instructions, etc.)
-
- 'dar' is the memory location, for traps 00300, 00400, 00600, 00A00.
- 'dsisr' has the following bits under trap 00300:
- 0 - direct-store error exception
- 1 - no page table entry for page
- 4 - memory access not permitted
- 5 - trying to access I/O controller space or using lwarx/stwcx on
- non-write-cached memory
- 6 - access was store
- 9 - data access breakpoint hit
- 10 - segment table search failed to find translation (64-bit ppcs only)
- 11 - I/O controller instruction not permitted
- For trap 00400, the same bits are set in SRR1 instead.
- For trap 00600, bits 12-31 of the DSISR set to allow emulation of
- the instruction without actually having to read it from memory.
