[LLVMdev] Clang build "clang-native-arm-cortex-a9" is broken
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:

Including a vector element in an if statement
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] <

[LLVMdev] fmac generation for cortex-a9
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 !

[LLVMdev] fmac generation for cortex-a9
Hi Bastien,
Weird gcc is generating fma for my platform STEricsson Novathor with Linaro, code works. It also works when I use LLVM to generate fma (using llc -mtriple=armv7-eabi). Maybe someone from ARM can answer the question ?

Yeah. That code has been there since r91421 and wouldn't have failed recently otherwise. Did something change on the host?

prediction problem
Hello,
I am using the mda package and in particular the fda routine to
classify/predict in terms of color to a set of 20 samples for which i don?t
know the color.
I preformed a flexible discriminant analysis (FDA) using a set of 147
samples for which i know all the information.
My script and data follow in attachment.
A total of 23 predictors were considered. 20 of the predictors are

[LLVMdev] fmac generation for cortex-a9
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 ?

[LLVMdev] fmac generation for cortex-a9
cat /proc/cpuinfo ?
Are you sure it's generating VFMA and not VMLA?

[LLVMdev] fmac generation for cortex-a9
Hi Sebastien,
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?

[LLVMdev] fmac generation for cortex-a9
AFAIK A9 doesn't have VFPv4 or AdvSIMDv2, so it doesn't have VFMA. I don't
know what LLVM does, but it shouldn't emit VFMA when you target A9. VMLA
isn't a fused multiply-add, it's a multiply followed by an add and has
different latency as well as precision.

[LLVMdev] vmlx forwarding an cortex A9 question
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 complex example disabling

Performance degradation on ARMv7 (cortex-a9)
Thanks Bradley.
I see that the features set in /ARM.td/ get written to the generated

ProcA9 features appear in /ARMFeatureKV/ table:

[LLVMdev] RE : fmac generation for cortex-a9
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 ?

Does anyone have an idea why the A9 bots are unstable on Clang? They
all seem to be the same problem:

[LLVMdev] [cfe-commits] Clang build "clang-native-arm-cortex-a9" is broken
I have tracked it down to the real reason.
The revisions 139934-139937 has changed the order in which configure
chooses a compiler. Clang is checked first, then llvm-gcc, and then
gcc.
I can see the reason for this change.
However, in this particular case it has broken the build because
Ubuntu includes clang 2.8 which doesn't know where includes are.
I have removed clang from the host to

[LLVMdev] Is there any llvm neon intrinsic that maps to vmla.f32 instruction ?
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).
