[Activity] Week 34
Summary: * Identify the root cause of performance regression for the "split2" patch. * Validate Linaro binary toolchain prerelease. Details: 1. Identify the root cause of performance regression for the "split2" patch. * Code alignment is the root cause for the performance regression (Michael reproduced it with "__attribute__ ((aligned(16)))"). * "build-id" section is the root cause of result difference from cbuild test (the additional section makes the function address different). * Workout a small case to show the impact of code alignment on performance. 2. Linaro binary toolchain 2012.08 prerelease validation. All tests pass. Absence: * Annual leave: Aug. 24. Plans: * Linaro binary toolchain 2012.08 release. * Start shink-wrap work.
