Nick, First, thanks for responding. Secondly, I just want to create an exact copy of an already exisitng Value, this should be pretty simple to do but I'm unclear on how to do this? For example, PHINode::getIncomingValue (unsigned) returns a "Value" and I want to make a copy of that Value. Is there some other way to do this other than copyValue() that I'm missing? On Sat,

Hola a tod en s, explico lo que estoy intentando hacer... Tengo un listado de url comprimidas de twitter, entre las cuales hay muchas repetidas, por lo que el número de registros llega a más de 15K.

I'm trying to understand how predicated/masked instructions can be generated in llvm, specifically an instruction where a set bit in the mask will write the new result into the corresponding vector lane in the destination and a clear bit will cause the lane in the destination to remain what it was before the instruction executed. I've seen a few places that suggest 'select' is the

Hi Everybody, I recently did a cross-compiling using clang (built with host=x86, target=arm) with the following command: > clang -march=armv7-a -mfloat-abi=soft -ccc-host-triple arm-none-linux-gnueabi -integrated-as main.c -o main.o -c and get error message: ------------------------------------------------------- main.c:9:9: error: instruction requires: thumb2 "ldrex

It works. But a follow-up question: why do I have to compile it to thumb mode in order to pass the compilation? Is there a way to make it compile to regular arm mode?

Hi, I have added an insertAfter method to the ilist and Instruction classes. The methods are implemented as efficiently as the currently existing insert and insertBefore methods. The insertAfter method was created to mirror a similar method in another compiler in order to ease an ongoing port. The patch, which is very small is included as AddInsertBefore.patch. Additionally, I wrote a small test

Sure. Use legal ARM mode syntax for the instruction. Specifically, there is no offset immediate for the ARM mode LDREX instruction. It's illegal syntax to supply one, even if it's zero. -Jim On Aug 16, 2012, at 2:36 PM, Lei Zhao <leizhao833 at gmail.com> wrote: > It works.

Ah, I think I get it now. This was mentioned earlier in the thread, but it didn't click at the time. It sounds like I can do instruction selection with a pattern like (omitting selection of the sources): let Constraints = "$dst = $oldvalue" in { def MASKEDARITH : MyInstruction< (outs VectorReg:$dst), (ins MaskReg:$mask, VectorReg:$src1, VectorReg:$src2,

Hi, Has anyone successfully implemented the :onsubmit option for form_remote_tag. It doesn''t seem to work for me. Is there any specific version of rails which is required for the same.

I am having difficulty in replicating a sequence of instructions (2+, with def-use dependencies within) and inserting them at a different location. I have tried a few different approaches (IRBuilder, new Instruction(), I->clone(), insertBefore/insertAfter,etc.), all leading to the same error msg: "Instruction doesn't dominate all uses" The DevList has a few previous
