==Progress=== * Some upstream patch review. * Spent time looking at LP 836588 which is a case where CSE removes a particular label access in one case but doesn't remove it from the list of things in the constant pool which is quite bizarre. Will probably need some help with looking into this one.

agenda for today's call.

[Activity] Week ending 14th October 2011

Short week with 2 days gone on an internal training course ==Progress=== * Some patch review. * Spent time looking at LP 836588. * Tried some different approaches for the vcvt.f64.s32 case and it looks like the simple solution is the best one unfortunately :( * 2 days off at internal training

[Activity] Week ending 7th Oct. 2011

==Progress=== * Out of office for a day. * Wrote a quick patch to do vcvt.f32.s32 with fractional bits where we can. Tested no regressions, need to commit this after review upstream. * Desk move and packing for that. * Looked at a bug report LP 836588 appears to go away with fno-gcse. Needs more

[RFC ARM] Use vcvt.f32.s32 with immediate bits to do fixed to floating point conversions.

patterns need to be written up at some point for completeness ) cheers Ramana 2011-10-04 Ramana Radhakrishnan ramana.radhakrish...@linaro.org * config/arm/arm.c (vfp3_const_double_for_fract_bits): Define. * config/arm/arm-protos.h (vfp3_const_double_for_fract_bits): Declare

==GCC== Combined report for last 2 weeks - ===Progress=== * Committed conditional compares patch to Linaro GCC 4.6 * Looking at modelling auto-inc-decs better . * Tried patch for PR19599 and that broke bootstrap with a segfault. Needs some re-engineering. * Looked at the latest bootstrap

[Activity] Weekly report for w/e 2011-09-09

==GCC== ===Progress=== * Fixed https://bugs.launchpad.net/ubuntu/+source/gcc-4.6/+bug/838994 . Investigated Bernd's alternate patch . Will commit mine. * Looked at PR48308 for sometime whihc might be a dup of PR50313 . * Some blueprint foo. * Committed a few of the outstanding approved patches

==GCC== ===Progress=== * Looked at the vectorize_with_neon_quad failure again and decided that I had to handle another case but not convinced that the extra stall we'd get in this case was worth it. In any case it would have been a workaround but Richard Sandiford fixed this by getting df to do

perf call tomorrow.

Hi, I've put up the agenda for tomorrow's call here. https://wiki.linaro.org/WorkingGroups/ToolChain/Meetings/2011-08-23 Please feel free to add to the agenda if there's something we want to bring up for discussion. cheers Ramana ___

Re: What are the chances of a phone based developer image

. Would you be interested in adding a Firefox-based benchmark? As a large application it is a good testbed for LTO, FDO and other aggressive optimizations. Sorry about the delayed response. I did notice your mail last week but I was busy with our conference and then the first couple of days

tomorrow's call cancelled.

Given I'm away at some internal training and we had one last week . I decided to cancel this. Ramana ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain

== GCC == === Progress === * ivopts patch to minimise the amount of VFP moves to integer registers because of auto-inc - sent out for review. It appears to test fine and reduces the number of FP to integer moves in certain SPEC2k6 benchmarks by about 20% * More cases with vfp moves identified

[Activity] Week ending 2011-06-17

== Progress == * Backported A5 / A15 tuning to Linaro GCC. Waiting for test results. * T2 perf. meeting. * Backported the neon length patch back. * Patch for PR49385 being tested. * Bootstraps broken yet again / upstream maintenance / test regressions. * Waiting on Branch_cost results . * Minor
