Hello everybody, Just a short note that clang build "clang-native-arm-cortex-a9" is broken and the very last successful build was for revision 139932. All newer revisions fail. The builder is available here: http://172.16.0.135:8011/waterfall Thanks Galina

Hi all, I've searched high and low on this and found nothing of help. I'm using v2.6.2 and trying to write a function that will count how many people from a dataset fall under a poverty line of 50% of the mean income. a9 is my 100-element vector of incomes. I want pa9 to be my vector that counts how many of these are classed as in poverty. My problem is that my command if(a9[i] < mean(a9)/2 ) returns an "argument is of length zero" error. But a9[i] is not really of length zero; if I remove the if() co...

Hi Renato, It's definitively not A15. Can this be the case that NEON units for cortex-A9 support it but isn't documented/recommended ? And as mentioned before code is working !

Hi Anitha, Thanks for your answer but -mcpu=cortex-a9 -mattr=+vfp4 doesn' t enable fused mac generation for me. I would like just to understand why -mtriple=armv7-eabi enables it while -mcpu=cortex-a9 seems to disable it ?

...n, ARMv7-M has VFMA and LLVM's "triple" is far from perfect. Wikipedia tells me NovaThor can also be A15, or STE could have cramped a VFPv4 in it? ;) Or possibly, your code never branches into the VFMA. Many things could be happening, but usually, VFMA shouldn't be generated for A9. A GCC bug, maybe?

Hi all, On following code when I use llc targeting ARM Cortex-A9 as follows, if vmlx-forwarding is turned off then 'vmla' instructions are generated. It seems that -mcpu=cortex-a9 enables it by default and thus less 'vmla' instructions are generated. On this specific example it doesn't make any difference in term of performance, but on a more...

Thanks Bradley. I see that the features set in /ARM.td/ get written to the generated file /<build>/llvm/lib/Target/ARM/ARMGenSubtargetInfo.inc./ Here the ProcA9 features appear in /ARMFeatureKV/ table: /{ "a9", "Cortex-A9 ARM processors", { ARM::ProcA9 }, { *ARM::FeatureFP16* } }, /With your change, the features for ProcA9 in the above entry are empty.//This ARMFeatureKV table is then read in MC/MCSubtargetInfo.cpp in the getFeatur...

Hi Renato, You're right it's VMLA/VMLS that are generated. Still don't understand what drives generation for Cortex-A9. I was using fmac for floating point MAC not for fused MAC. Than I realized that we spoke about fma instead of fmac. So back to the original problem why when using -mcpu=cortex-a9 VMLA/VMLS are not generated and when I use -mtriple=armv7-eabi they are ?

Understood, Same architecture, different micro-arch (implementation). Could this be the case that vmlx-forwarding make senses for SWIFT and not for ARM Cortex-A9 implementation ? It is enabled by default when -mcpu=cortex-a9 is used but test have made show significant improvements when disabled for cortex-A9 (STEricsson Nova platform).
