[LLVMdev] Help needed on debugging llvm
I'm still slightly confused. Is the error now fixed or is there still a bug
in LLVM's integrated assembler?

Unfortunately r173176 does not fix this. I have updated the trunk and

[LLVMdev] Dragonegg build broken?

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.

[LLVMdev] Help needed on debugging llvm
Hi Duncan
I am facing a build error about __builtin_iceil when compiled
with dragonegg using -ffast-math option. My dragonegg is built with
gcc-4.7.0
(I am compiling namd spec benchmark here again).
Any idea?
g++ -march=bdver2 -save-temps
-fplugin=/home/anboyapa/install/bin/dragonegg.so -O2 -march=bdver2
-save-temps -fplugin=/home/anboyapa/install/bin/dragonegg.so -mno-fma

The error is not fixed yet (even with fix mentioned in PR15040

With the updated trunk, clang still gives an error when FMA4 is

[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] Any support for zeroing buffers?
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!

It seems to be so! I will look into it immediately.
Apologies for the late e-mail. I ran out of time devoted for this PR
and moved on. Coincidentally, only today I came back to this PR for

[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 ?

[LLVMdev] Pat operands matching example in ppc
Hi,
How do "Pat" operands get matched? I am trying to follow the example given
in http://llvm.org/docs/CodeGenerator.html#selectiondag-process
In the latest trunk of ppcintrinfo.td following pattern is defined:
def : Pat<(pre_store i32:$rS, iPTR:$ptrreg, iaddroff:$ptroff),
(STWU $rS, iaddroff:$ptroff, $ptrreg)>;
I understand that input operand list i.e. ins of

you are right, dragonegg does not use the integrated assembler.

[LLVMdev] Operand order in dag pattern matching in td files
Hi,
I have a simple question w.r.t the order of operands used in dag
pattern matching in target files. Some of them seem intuitive. But I
want to get it clarified anyway. I am using a pattern from
X86InstrFMA.td in the below example. Consider FMA3 pattern
(simplified).
let Constraints = "$src1 = $dst" in {

[LLVMdev] X86 Tablegen Description and VEX.W
Hi,
A question from r162999 changes:
http://llvm.org/viewvc/llvm-project/llvm/trunk/lib/Target/X86/X86InstrFMA.td?r1=162999&r2=162998&pathrev=162999
For the multiclass "fma4s", why is "mr" not inherited from "VEX_W" and
"MemOp4" like those of "rm" or "rr" ?
multiclass fma4s< >
