Looks like recent changes to Attributes.h broke the dragonegg build.

Can you send the binaries compiled with and without the integrated assembler. Maybe I can figure out the encoding problem. I've been unsuccessful figuring it out myself so far.

I'm still slightly confused. Is the error now fixed or is there still a bug in LLVM's integrated assembler?

...ug with LLVM's integrated assembler. On a related note, r173176 mentioned in http://llvm.org/bugs/show_bug.cgi?id=15282 does not fix the gromacs miscompare error either. However -no-integrated-as helps in all cases. I am not sure if r173176 is incomplete or the issue is something else. -Anitha > > On Mon, Mar 11, 2013 at 4:49 AM, Anitha B Gollamudi > <anitha.boyapati at gmail.com> wrote: >> >> On 11 March 2013 17:00, Duncan Sands <baldrick at free.fr> wrote: >> > Hi Anitha, >> > >> > >> >> Ah, I am taking back my a...

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 ? Seb > -----Original Message----- > From: Anitha Boyapati [mailto:anitha.b...

Hi, Is there any existing support/on going work for zeroing buffers in llvm infrastructure? (either in the form of intrinsics or IR code buffer erasure?) My basic "grep" did not show up any. Please let me know any info on this. I will be glad to hear out! -- Anitha

...w 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.
