== Summary == - http://cards.linaro.org/browse/TCWG-14 Coremark ARM mode gives about 2% performance improvement with about 1% code size reduction. Thumb2 mode however has performance regression even though code size reduces about 0.6%. Performance regression here is like what we are seeing in EPILOGUE_UESES changes(http://cards.linaro.org/browse/TCWG-13). Spawned spec in CBUILD to see the impact with spec2000.

- http://cards.linaro.org/browse/TCWG-13 Thumb2 mode performance regression is due to the percentage of time spent in core_state_transition. Looks like an alignment issue; same asm is generated for this function with the patch. Investigating it.

== Plan == - Plan to resolve http://cards.linaro.org/browse/TCWG-13 this week. - Get spec2000 results for http://cards.linaro.org/browse/TCWG-14 to decide on the next step
