== 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
