similar to: [LLVMdev] Fortran alternate entry points in LLVM IR?

The input language is at assembly level, and the location akin to a %temp ( a virtual register if you will) and contains moves from one virtual to another. Though these are not like memory but I could represent them as local variables and do loads and stores; so I dont know how to represent it in C except as local variables.

Hi, A way to handle moves is to have an array mapping virtual regs to the llvm instructions which compute them. Then a dr <- sr move can be handled by doing reg_to_inst [dr] = reg_to_inst [sr]. And whenever sr is used as an input to an operation, use reg_to_inst [sr] instead. Zoltan On Fri, May 29, 2009 at 1:23 AM, Vinod Grover <vgrover528 at gmail.com> wrote:

Sorry if this has been discussed before, but I would appreciate any pointers. I am trying to understand why mem2reg only looks at allocas in entry blocks, and not for any allocas in a function. One case where allocas could be used to build local data structures like linked list (and so on make it unsafe), and for that the existing conditions in IsAllocaPromotable (i.e. the alloca pointer cannot

Unfortunately that does not work, since the bitcast will generate a convert and the argument of the intrinsic will be a value type i8* and the intrinsics is intended to map to an instruction that accepts only a symbolic. The convert gets hoisted, possibly to a different block, and we would like the symbolic variable to stay as an operand of the intrinsic making it possible to write the correct

A value in LLVM normally doesn't have that sort of identity... what

you can use an add with zero, if you dont think you are adding redundancy.

In our experience, as Owen also suggests, a pragma or a language extension can be avoided by a combination of static and dynamic analysis. We prefer this approach in our compiler ;) Regards, Vinod On Sat, Jan 24, 2015 at 12:09 AM, Owen Anderson <resistor at mac.com> wrote: > Hi Jingyue, > > Have you considered using dynamic uniformity checks?

I was looking at the LLVM IR documentation and was wondering if it is possible to define LLVM intrinsics which might be a pointer to some pre-defined struct or opaque types?If that is possible how would one go about doing that ?

Do you know how to do the action you seek in C? If yes,

You mean something like FILE*? It's not possible to do that, but you can just define it

I'm trying to build R 1.9.0 to get the opportunity to build rpy for some folks at my office. (I'm a Python guy, not an R guy, so I'm completely unfamiliar with the machinations of building R.) I'm having trouble getting past the configure step. A plain old configure generates this output at the end: checking whether we can compute C Make dependencies... yes, using gcc -MM

I want to plot variation of more than one variable in single plot with different point types and points sizes . Can someone help me to do that, Thanks in advance. vinod ____________________________________________________________________________________ Now that's room service! Choose from over 150,000 hotels

Is inlining (which duplicates code) of functions containing OpenCL style barriers legal?or e.g. if you had some changed phase ordering where you had if (cond) { S1; } call user_func() // user_func has a barrier buried inside it. you do tail splitting if (cond) { S1; call user_func() } else { call user_func(); } now you inline -- oops now you might have a problem so do you want
