This patch is related to a recent change in the way gcc generates function epilogues for arm targets (since gcc trunk r188745): http://gcc.gnu.org/ml/gcc-patches/2012-05/msg02071.html The function arm_in_function_epilogue_p does not recognize POP with a single register as a stack adjustment in arm mode. It causes two test new failures in gdb testsuite: FAIL: gdb.base/watch-cond.exp: watchpoint with local expression, local condition evaluates in correct frame FAIL: gdb.mi/mi2-watch.exp: hw: watchpoint trigger (stopped at wrong place) The reason is that in arm mode the encoding of POP with single register is different from the encoding of POP with multiple registers. The attached patch adds the missing pattern to arm_in_function_epilogue_p. Thanks, Greta ChangeLog gdb/ 2012-06-25 Greta Yorsh <Greta.Yorsh@arm.com> * arm-tdep.c (arm_in_function_epilogue_p): Recognize POP with a single register as a stack adjustment in arm mode.
