This is a long-known limitation of LLVM IR and there are a lot of proposals to fix it. It would be great if the LLVM Foundation would fund someone to do the work, as it

Thank you for your answers. In fact I'm still hesitating between C and C++, sorry for my incomplete message. What I want to write is some sort of DSL; so I can afford both I think. I'm thinking about generating standard-compliant code using numeric limits and stuff; given that I don't care about compilation time or debugging, I think I can still use C++ in case I decide to include

It aims to be able to express anything that arbitrary source languages might want and anything that target architectures may implement, in a way that is not closely tied to either specific source languages or target architectures.

I think it would be possible to build a stripped-down C-with-extensions-only type representation that represents only the types that have interesting ABI implications. This includes several things not present in LLVM IR types: _Complex, union, flexible array members, alignment attributes, etc. We could either then use that library to generate LLVM IR, or embed it in the IR for use at call sites.

In this email, I argue that LLVM IR is a poor system for building a Platform, by which I mean any system where LLVM IR would be a format in which programs are stored or transmitted for subsequent use on multiple underlying architectures. LLVM IR initially seems like it would work well here. I myself was once attracted to this idea. I was even motivated to put a bunch of my own personal time into

I have a requirement where I want a Fact to be stored in PuppetDB during the manifest run and not during the initial fact gathering phase. I know I can, in my manifests, create a file in /etc/facter/facts.d or I can write a Ruby script that will then be distributed by plugin sync. But both of these methods will only publish the fact during the initial phase of the puppet agent run. What I

Greetings All, I am sending this mail on behalf of the OpenCL Khronos members. **** Introduction **** Lately, Khronos has ratified a new provisional specification which is called SPIR. This specification standardizes an intermediate representation for the OpenCL kernel language. It is based on LLVM infrastructure and this is why I am sending this mail to the LLVM mailing list.

It sounded as if you were talking about a library that sits underneath such a thing. Lots of languages have their own runtime

Hello. I want to get the proper influence function for the glm coefficients in R. This is supposed to be inv(information)*(y-yhat)*x. So I am wondering what is the exact mathematical formula for the output that the functions: dfbeta() OR lm.influence()$coefficients return for a glm model. I am confused because: 1. Their columns don't sum to zero as influences should. 2. They
