== 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
