[ACTIVITY] Week 04
== Issues == * None == Progress == * Investigate to duplicate shared compares to get more conditional compares. * Investigate to enable shrink-wrap for TARGET_APCS_FRAME. Still some ICE fails in regression tests. * Help on cbuilv2 eglibc multilib build issues. == Plans == * Tuning ccmp performance * Enable shrink-wrap for TARGET_APCS_FRAME. == Planed leaves == * Jan. 31 - Feb. 10. ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
[Activity] Week 04
Summary: * Investigate Automotive benchmark performance on different branch cost. Details: 1. Automotive benchmark performance analysis for different branch cost on Pardaboard ES. * Design small test cases to simulate bitmnp01 to compare the performance between ITTT and conditional branch. Test results show - If branch prediction does not work (put the codes in a function), ITTT is always better than conditional branch. - If branch prediction works (inline the codes t in the loop body), for most cases, conditional branch is better than ITTT. * Code alignment has big impact for tblook01. By default IT block has better performance. When adding __attribute__((aligned (16))) for function t_run_test, performance of conditional branch is better than IT block. 2. Prepare Linaro toolchain binary release. * Update Linaro crosstool-ng local patches due to the fix of lp:1067766 in source package. * Spawn all builds and smoke tests. Plan: * Investigate SPEC2k performance for different branch costs. * Work with Bero for 2013.01 toolchain binary release . Planed leaves: * Feb. 9 - 15: Chinese Spring Festival.
