OR1200 debug unit: prevent deadlock when trap instruction stalls
As per mailing list post <20120925160925.5725e06f@latmask.vernier.se>,
the debug unit could deadlock with the instruction decoder if the trap
instruction is held back by a pipeline stall. This change prevents that.
The problem can be reproduced by placing a breakpoint at an unfavorable
position with instruction cache enabled. In our test, this occurred
with or1200-cbasic when placing a breakpoint at test_bss using gdb, but
this is dependent on such factors as cache parameters and compilation
result. |
