similar to: [LLVMdev] LLVM JIT and Java Reflection style calls

I have just worked with this code. The architecture is fine, and I think that this code should be reused, It needs updating, however, because it does not compile with LLVM 2.1 (I prefer to use a stable version to focus my work, and port to LLVM 2.2 later). I have seen that one incompatibility is that this Java frontend requires C++ with exceptions, but LLVM is compiled with -fno-exceptions. For

Hi, I'm looking for interprocedural AAs and have, of course, found https://llvm.org/docs/AliasAnalysis.html. However, the AAs that come bundled with LLVM do not work interprocedurally in a way that I need it (on/with stack variables). The two interesting looking AAs come with the optional `poolalloc' module that hasn't been updated in years (I guess

Thanks again. One more question here: Since the regalloc works once per function, do I stil have access to the Call graph? Just saving information between regalloc passes for different functions may not be enough for my case. I will need to maintain the regalloc info of various passes in the call graph order. Anyways thanks for your inputs. I will get back if I need to learn more. Sanjiv On Nov

Hi, again, I think you can do it in the same way that the other allocators have been coded, i.e extend RA, register the pass and so forth. I am not sure about the best way to pass information among a run of RegAlloc to the other, maybe the other guys in the list could suggest something. Yet, you can always dump it into a file, and read it again, everytime it is necessary. Remember that

Hi! I'm trying to implement in R in an easy way the negative reflection method described in Silverman (1986) on p.31, ie I have a non-negative dataset and would like to estimate the density by applying a reflection method where the reflected points have weight -1. I thought there should be a way to evaluate the wanted kernel at the required points, in other words to calculate formula (2.16):

Thanks both. I looked over the getelementptr and bitcast documentation but I am still a bit confused by one point. lets say i have something like this. union { long Int; double float; long* IntRef; } Since pointer sizes are platform dependent if I am trying to use the union in question with an extern C function is it possible to make write the single definition in a platform independent way?

Hello everyone, I have been interested in compilers, especially in the optimization aspects from quite some time now. I don't know if I have a decent background to brag about, but all I can say is that I have tried very small things related to building a compiler [0]. However I admit that I am still new to a lot of things. Like many others who are interested in compilers, I am interested

Hello, I have a question. I would like to know if there is a way with the reflection and respond_to? to know if there is a relationship between tables. When I say that I mean if inside a model there is a Has_many or belongs_to declaration. Because I try to get this information dynamically, during the execution of a script. If someone has an idea even if it''s not with the reflection,

Hi, I would like to know if there is a way to maintain database reflection for the ''new'' and ''edit'' views whilst removing scaffolding? I''m trying to create a webapp that will be somewhat maintainable by colleagues (that aren''t necessarily web developers) through simple manipulation of db table fields. For example to add another field to the

I am trying to write a ModulePass which requires PostDominator sets for every function in the module. Now finding post dominators is a function pass. The link on the llvm.org website says that : "Currently it is illegal for a ModulePass<http://llvm.org/docs/WritingAnLLVMPass.html#ModulePass>to require a FunctionPass <http://llvm.org/docs/WritingAnLLVMPass.html#FunctionPass>.
