3.2 Core.1: Incorrect update of the Abort Link register in Thumb state
Introduction:
If the processor is in Thumb state and executing the code sequence STR, STMIA or
PUSH followed by a PC relative load, and the STR, STMIA or PUSH is aborted, the PC is
saved to the abort link register.
Problem:
In this situation the PC is saved to the abort link register in word resolution, instead of
half-word resolution.
Conditions:
The processor must be in Thumb state, and the following sequence must occur:
<any instruction>
<STR, STMIA, PUSH> <---- data abort on this instruction
LDR rn, [pc,#offset]
In this case the PC is saved to the link register R14_abt in only word resolution, not
half-word resolution. The effect is that the link register holds an address that could be #2
less than it should be, so any abort handler could return to one instruction earlier than
intended.
Work-around:
In a system that does not use Thumb state, there will be no problem.
In a system that uses Thumb state but does not use data aborts, or does not try to use
data aborts in a recoverable manner, there will be no problem.
Otherwise the workaround is to ensure that a STR, STMIA or PUSH cannot precede a
PC-relative load. One method for this is to add a NOP before any PC-relative load
instruction. However this is would have to be done manually.
