== 64 bit atomics == * Thanks to Ramana for OKing my gcc patches; and Richard for committing them - I've backported these to the gcc-linaro branch and pushed it - hopefully those will pass OK! == String routines == * Sent my memchr patch to upstream newlib, received comments, tweeked, and resent * Sent strlen patch to upstream newlib * Spent some time getting confused by timing issues on our Panda; it got reinstalled with 11.09 a few weeks ago and is now showing some odd behaviours. In particular I'm seeing some tests show completion in 0ns (and my code isn't -that- fast!), and others where the times vary wildly - it's almost as if a timer interrupt is delayed or missing; my same test binary works fine on one of Michael's Ursa's running an older install. == QEMU == * Tested Peters QEMU image for release == Other == * Spent an afternoon reading through the System trace docs On holiday next week; I'll poll email occasionally.

upstream planning using Linaro process

by Mounir Bsaibes

A lot of concerns were raised about how to plan for upstreaming work using Linaro process while there is no guarantees for acceptance. Deepak has setup a session to address this issue and come up with a reasonable solution to the problem. In preparation, I have put together this google doc and shared it with all in Linaro. https://docs.google.com/a/linaro.org/document/d/1Inj3Esvk4Lbqe5PN7NHnK1WKRa… Please take a look at this document ahead of the session, if you have a proposal for a solution (or any other feedback) please let us know, so we can add it to the discussion. We are hoping a lot of engineers would provide feedback and attend the session so we can come up with a conclusion. To subscribe to the session please follow: https://blueprints.launchpad.net/linaro/+spec/linaro-general-upstream-proce… Thanks & regards, Mounir -- Mounir Bsaibes Project Manager Follow Linaro.org: facebook.com/pages/Linaro/155974581091106 http://twitter.com/#!/linaroorg http://www.linaro.org/linaro-blog <http://www.linaro.org/linaro-blog>

Hi, * Finished a presentation for NEON forum. Revital and Richard kindly agreed to take a look and gave me some valuable comments. Thanks! * widen-shifts: - While preparing the presentation I found some room for improvement in the pattern detection, so I implemented it. It gave additional 13% to rgb24tobgr16. - Ramana suggested a solution on how to check the constant operand of vshll. Testing these two things on ARM. * SLP improvements: - Implemented a patch that swaps operands if necessary to make the operations isomorphic, and supports loads with different offsets. Testing it now. - The three relevant libav loops now get vectorized giving 42%-57% speedup. Next week holidays: half days Sunday-Wednesday and Thursday. Ira

Binary toolchain questions summary

by Michael Hope

Here's my summary from Monday's meeting on the harder parts of binary toolchains. Using a 4.6 compiler against a 4.5 based sysroot such as Natty: * libgcc and libstdc++ are part of the compiler * The compiler expects features that are in the corresponding runtime * You can't reliably run or validate against an earlier runtime The solution is to upgrade the runtime on the sysroot to 4.6. 4.6 is backwards compatible. Ubuntu did this with Maverick and it caused no problems, although problems such as Debian #622783 have been seen. Multiarch: * The Ubuntu multiarch patch should work with a sysroot * Multiarch and multilib should work together Multilib: * The current ARM multilib rules are old and not very relevant * Multilib means you need multiple sysroots as well * Skip multilib for the first release Other: * Anything we support in cross we should support native first * Check that we don't have to directly supply the source that goes with the binary sysroot -- Michael

Native build performance

by Michael Hope

Random data for the day: Dave Pigott has installed some new PandaBoard build machines in the validation lab. They're identical to mine except that root is on USB Flash instead of NFS, and they have a much faster flash drive for the build area. The time taken to bootstrap and test gcc-linaro-2011.09 with C, C++, Fortran, and LTO is: * ursa3, ursa4 (Toshiba USB stick): 301 minutes build / 369 test * ursa2 (no-name USB stick): 324 minutes build / 422 test * tcpanda (fast USB stick): 274 minutes build / 265 test So the new combo gives a 1.38 x faster build. I'm surprised as I though the build was CPU bound. I'd hate to see what building on an SD card is like. Note that /tmp is in RAM, /scratch is ext4, the new boards use noatime, and the kernel doesn't have the new USB performance fix. -- Michael

Re: Use of memcpy() in libpng

by jbowler＠acm.org

The unaligned accesses in libpng are, for the large copies, a bug. Our attempt to align the row buffer to a 16 byte boundary was off-by-one so we end up always mis-aligning it. I've posted a patch on the png-mng-implement list: http://sourceforge.net/mailarchive/message.php?msg_id=28194444 The time spent in memcpy() is probably an illusion. The data out of zlib gets copied to one row buffer where it is unfiltered (if necessary) then a copy is made in a separate buffer that is only used for the filter handling. If you test using images with large rows (I don't know what pngbench does) the copy buffer may well get flushed out of the second level cache between each row, then the memcpy will stall bringing it back in. If you have machine level profiling you may see this as a massive time spike on some probably unrelated instruction which just happens to be in the PC when the stall stops everything. Anyway, I have several ideas of how to avoid the copy when it isn't required.

It wouldn't take long to analyse the memcpy calls - life would be easier if we had the test program and some details on things like what size of images were used in these benchmarks. Dave

[ACTIVITY] 3rd - 7th October

Continued work on my constant reuse optimizations. Not too much this week though. I've now fixed some issues with the ARM size-costs code that was causing it to wildly over-estimate the cost of a MOVT instruction. I'll have to post this upstream sometime soon. Took another look at the shift-amount bug. Discussed the issue with Paul Brook. I've now fixed the original bug, and fixed the new bug introduced by Paul's original fix, and committed that upstream. I still need to backport it to Linaro GCC though, and the latent bug that Richard S spotted is still being analysed. Did a merge from FSF 4.5 & 4.6 to Linaro, and pushed them the Launchpad branches for testing. Begun work benchmarking different setups for the generic tuning patches. I had a lot of trouble trying to set up SPEC2000 though. Hopefully these issues are now resolved, with some help from Michael, and I have established some baseline figures on both A8 and A9 to work from. No progress on native tuning. I'm still waiting for upstream review. In other news: Mentor's contract with Linaro has now been extended for another 6 months. :)

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

by Ramana Radhakrishnan

Hi, So one of the things Michael pointed out in today's call was that the ARM backend doesn't generate vcvt.f32.s<type> where you have an idiom conversion from fixed to floating point as in the example below. I've chosen to implement this in the following manner in the backend using these interfaces from real.c . The reason I've chosen to not allow this transformation in case flag_rounding_math is true is because this instruction always ends up rounding using round-to-nearest rather than obeying whats in the FPSCR and thus is not safe for programs that want to dynamically set their rounding modes. The benefits are quite obvious in that we eliminate a load from the constant pool and a floating point multiply and thus essentially shaving off a floating point multiply + Load latency off these sequences. This instruction can only write the output into the same register as the input register which is why I've modelled it as below by tying op1 into op0. If there's a simpler way of using the interfaces into real.c then I'm all ears ? Thoughts ? I believe such idioms are used in libav from where the original report appears to have come and thus it's a worthwhile gain where we can have it. Any other places where folks might have noticed this. I will post upstream as well once I finish testing this patch. I'm posting this here to get some feedback as well to let anyone who is really really keen about trying this out have a go given I'm out tomorrow. ( I took a quick look at the short -> f32 case as well but the fact remains that loads either zero or sign extend anyway so there's probably not much gain in modelling that right away and the win really is in getting rid of that fp mul and the constant pool load. There's probably some gain in going from i64-> f64 as well so those patterns need to be written up at some point for completeness ) cheers Ramana 2011-10-04 Ramana Radhakrishnan <ramana.radhakrishnan(a)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. * config/arm/constraints.md ("Dt"): New constraint. * config/arm/predicates.md (const_double_vcvt_power_of_two_reciprocal): New. * config/arm/vfp.md (*arm_combine_vcvt_f32_s32): New.

* Vacation Monday, Tuesday, and Wednesday. * GCC Continued work on my constant reuse optimizations. Disappointingly, I've found that there are very few optimization opportunities in EEMBC (ARM/Thumb V7-A), although it's not difficult to write testcases that the optimization could improve. I also discovered that the data-flow chains don't work exactly how I thought (with respect to if-then-else cases) so I need to do a little more work. Pinged the native tuning patches; they're still waiting for upstream review. Still can't get the generic tuning work done as the CodeSourcery panda boards appear to be still offline.
