Hello, I'm trying to understand how fitting source integer type width into target machine register width happens. My reading on LLVM codegeneration topics (few megabytes) so far didn't have this topic mentioned explicitly. As an example, how %1 = add nsw i32 %b, %a gets compiled into msp430 (16bit CPU) assembly as: add.w r13, r15 addc.w r12, r14 Using -print-before-all

Hi, I have read an email from the mail list. And I have a question about loop rotation. What is it if it is the case below. -------------------------------------------------------------------------- loop: A br X B br Y C br loop, Z ------------------------------------------------- Thanks!

Hello, I'd be interested in knowing which pass performs loop inversion, i.e. transforms while loop into do/while wrapped with if. So, it's pretty easy to understand concept, http://en.wikipedia.org/wiki/Loop_inversion provides description of how its done and motivation, googling gives several relevant references, i.e. it's pretty settled term. I also see this transform to be actually

Hello, LLVM provides several ways to visual IR structure straight in its core - Function::viewCFG() to render control flow graph, then -view-* options to llc to render various stages of transforming to machine code. However, I wasn't able to find a way to render complete DAG visualization of normal IR - which besides CFG would also show dataflow (and other flows, if any). What people use to

Hello, I only recently started to look at LLVM assembly generated by Clang, and one of the first thing I saw was like: define i32 @foo(i32 %a, i32 %b) nounwind { %1 = tail call i32 @bar(i32 %a) nounwind %2 = icmp eq i32 %1, 0 br i1 %2, label %5, label %3 ; <label>:3 ; preds = %0 %4 = add nsw i32 %b, %a br label %7 I wondered what ";

hey, Sometimes there're Workarounds like "you'll need this dlls and this Wine Version". How can I use an older Version (0.9.58) without deinstalling the new? I tried it with PlayOnLinux, but there new problems appeared. greetz

  Hi Aries. Thanks very much! Precisely this is the situation! There're two consecutive branches (br1cond and br2uncond). Inside of AnalyzeBranch, there's an opcode swap of br2uncond (ex. j_foward to j_backward). There I do BuildMI (newOpcode) and followed by br2uncond->eraseFromParent(). This results in br1cond loosing it's label/offset. How could I resolve this? Best regards,

Hi, I am doing multiple regression, and have several X variables that are categorical. I read that I can use dummy or contrast codes for that, but are there any special rules when there're unequal #observations in each groups (4 females vs 7 males in a "gender" variable)? Also, can R generate these codes for me? THanks.

Hello, I'm writng this message to see if anyone knows how to analyze a data with geometrically distributed outcome. My situation now is : I have a outcome which is geometrically distributed. And I've also self-derived the link function for geometric distribution. I want to use generalized linear models to analyze it, but there're only models for binary data, poisson distributed

I'm preparing a few simple patches that will cleanup few things regarding new chain - in particular the ones I mentioned in Januray during discussion with Shao (tone down overkill abstractions, etc.). One question on a formal side though - which license is preferred at the top of the source files ? Currently there're two present - either something bsd-ish (on parts derived from

Hi All, I wanted to do some basic cost estimation of Instruction/BB. There're CostModelAnalysis and CodeMetrics available in 3.1 and 3.2 releases. I've been using 3.0 for a while. I'm wondering whether similar analysis can be done in the old 3.0 release, e.g. back porting the implementation. Thank you! Best, Ryan -------------- next part -------------- An HTML attachment was

Suppose I have a plot plot(1:10, pch = "") And I want some text to indicate a Normal distrubition. I could do this: text(5, 6, substitute(X~~~~N(mu, sigma^2)), adj = 0) text(5.35, 6, "~", adj = 0) But that's clumsy, and depending on your plotting device, might not even look sensible. I'd prefer to be able to do it more directly and simply the way these do: text(5,

Hi, Reason behind that is we have some use cases wouldn’t like to make some nodes to become the transit node, but there’re some other nodes in the topology act as the transit nodes. So if the tinc node forward subnet update it learning from one side to the other side, then it possible to become transit node if one side only have route to go through it. That node I would call it “spoke-only”
