Yes I agree with David, I don't think we can draw analogy between lambda and outlined routines.

Hi all, Is there a way to set up array ordering (DW_ORD_row_major or DW_ORD_col_major) using debug metadata ?

Not at the moment, we've been adding things that need additions to the metadata on an "as needed" basis. Do you have a language that allows you to swap orderings in source code? If so, then feel free to add it to the array type metadata and send a patch. -eric On Oct 3, 2013 1:15 PM, "sebastien deldon (PGI)" < sebastien.deldon at pgroup.com> wrote: > Hi all,****

It's designed to deal with types that may not be referenced via other metadata. Anonymous metadata not referenced by named metadata will be automatically removed. -eric On Mon, Sep 16, 2013 at 4:18 AM, sebastien deldon (PGI) <sebastien.deldon at pgroup.com> wrote: > Hi all, > > > > What is retained type list designed for in debug metadata ? > > > > Thanks for

Usually the array ordering is implied by the language; for example LLVM supports Fortran via Dragonegg but we still don't set the ordering explicitly, we rely on the debugger to assume the right ordering because of the language code. You wouldn't need to set ordering unless you want an ordering that isn't the language default, or you're using a language code that the debugger

Hi all, I'm using my own front-end that generates LLVM debug info metadata. I was using LLVM 2.9 debug version and I'm moving to LLVM 3.2 debug version of metadata. On my example I got llc 3.2 to fail on following assertion: llc: /work1/tools/llvm/3.2/sources/lib/CodeGen/AsmPrinter/DwarfDebug.cpp:1471: void llvm::DwarfDebug::endFunction(const llvm::MachineFunction*): Assertion `TheCU

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 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 ?

cat /proc/cpuinfo ? Are you sure it's generating VFMA and not VMLA?

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 ?

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? On 9 November 2012 16:51, Sebastien DELDON-GNB

Hi James, Thanks for the answer, for Cortex-A9 would you recommend to generate thumb2 code or ARM code ? What would be the best performance wise ?

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.

Understood for the aligned case, I want to measure performance degradation for unaligned case. I mean unaligned case versus aligned. I know this is stupid, but I want to try to pass a <4 x float>* as parameter of a routine and at the call site I want to pass a misaligned pointer. Since LLVM is generating movapd instruction it will raise an exception (SEGFAULT), I just want to know if there

Hi James, Thanks for the answer, can you elaborate on difference between thumb, thumb2, ARM, thumbv7. I'm a bit lost right now. When specifying thumbv7 llc will generate thumb only code, not thumb2 ?

Hi Lang & Renato, I eventually set up a panda board with latest linaro delivery (eabi-hf). I did some experiments using my own compiler and LLVM 3.2 as back-end. I use same flagset for my compiler (front-end) and just invoke llc with and without vmlx-forwarding attribute. So base arguments to llc are: llc -march=arm -mcpu=cortex-a9 -mattr=+neon -float-abi=hard to which I added

Hi Eli, Thanks for the answer, it clarifies the situation for me. Do you know if there is Pass in LLVM that could be adapted to 'legalize' intrinsics calls ? Or shall I define my own intrinsics for non supported types ?
