Hmmm... It seems like I should check out how the UseList on Value (and its child BasicBlock) work.

Hi all, I would like to discuss a design idea I have in mind with you, in order to get critical feedback. ActiveRecord supports single table inheritance(STI) "per se", BUT you must add all possible instance variables(properties) of all subclasses to the "base table"(as columns). I would like to circumvent this restriction. Say we have a class AbstractGenericThing <

Hello everyone! After I've checked out Clang and Compiler-RT repositories, I receive this error during compilation: llvm[5]: Compiling PathDiagnostic.cpp for Debug+Asserts build /media/data/dev/llvm/llvm/tools/clang/lib/StaticAnalyzer/Core/PathDiagnostic.cpp: In member function 'bool {anonymous}::CompareDiagnostics::operator()(const clang::ento::PathDiagnostic*, const

Since I uses rsync in a perl script I'd rather prefer to get error codes from rsync instead of messages at STDOUT. Is there an option which tells rsync it should return error codes? Is this possible or do I ask something ridiculous? How is the error handling done when rsync can't download a file? Should I better switch to the rsync library, is there a perl interface? O.

It's not caused by "the insertion point is set to the default after". I should mention the reason somewhere earlier. "Reversing the order of arg0~3 is not intentional. The user list of pixel_idx happens to have pixel_idx+3, pixel_idx+2, and pixel_idx+1 in this order, so LSR simply follows this order when collecting the LSRFixups." I'm not an expert on uselist orders,

Hello, I recently ran into an issue where I wanted to use dyn_cast with a Multiple Inheritance hierarchy. LLVM’s help page on RTTI claims that it can be done, and that Clang’s Decl and DeclContext implement it; however, when I try to use it I run into odd behavior. Here’s my sample code which doesn’t work: ``` struct Base { void *ptr; bool hasInfo; }; struct Info { int size; static

I try to write a pass that clones a function and then removes some instruction from the clone, the clone is then added to the module (the parent of the source function). I call removeFromParent() on the appropriate instruction and it is actually removed (I see it in module's dump). However I get a failed assertion at Module Verifier which says: --- Instruction referencing instruction not

Hi all, say I have a class Container has_many :items end and class Item belongs_to :container end Now if I fetch a container from the db cont = Container.find :first and then call cont.items 1000 times, does this result in 1000 db queries(for the items of the container)?

Hi Vadim, which compiler are you using to to the build, what platform are you on, how did you configure LLVM, clang etc ? Ciao, duncan.

Hi LLVM, If I have an llvm value "<16 x float> addrspace(1)* %in", and in the LLVM IR, there is a @llvm.dbg.value like: call void @llvm.dbg.value(metadata <16 x float> addrspace(1)* %in, i64 0, metadata !216, metadata !28), !dbg !217 How I can retrieve this @llvm.dbg.value when I have "%in"? Since Metadata is not a part of the uselist anymore, is there some way

Hi I just tagged 0.0.37 in Subversion. I also added a note on the Wiki on how to do this, and how to checkout a clean version: http://wxruby.rubyforge.org/wiki/wiki.pl?Release_HowTo For the build, I''m just about to upload a tarball, and will add a powerpc gem once the compiler''s chugged away. Please upload for your platform as you''re ready. I suggest we announce

Hi, Do you have some code we can look at (even if it is in a nasty unpolished state, just mark it WIP and put it on Phab) ? It is hard to evaluate an alternative without the code. That said I think that the table is a little bit one-sided. I have added some inline comments. On 30/12/2019 11:53, Ehud Katz wrote: > The solution in Clang is still very complicated and error prone.

Ok. I'm basically just following the model of the other fast-isel ports.

Been having a bit of a problem with dyn_cast: Suppose I have a class A that inherits from two base classes, both of which support dyn_cast. In order to use dyn_cast on A, I need to do a bunch of extra work: 1) Since dyn_cast uses reinterpret_cast rather than static_cast, the pointer value won't get adjusted by the cast operation, making the pointer invalid. I end up having to redefine

(I'm assuming you're building LLVM with clang, in this case?) Looks like IntrinsicInst is one of those "lies" in LLVM that works via type punning that's undefined behavior in C++, so it's code that should be fixed anyway. In any case, the reason this produces the debugging experience you're seeing is that LLVM (& GCC, for that matter) assumes that if your class

Hello, I have come across an unusual behavior where instruction domination rule is violated "Instruction does not dominate all its uses." It concerns with StackColoring pass present at llvm/lib/CodeGen/StackColoring.cpp. I am reaching out to the LLVM community to help me understand the cause of this issue and the working of the pass. The IR produced at the end of the pass seems to be

Hey, I'm trying to implement a GARCH model with Johnson-Su innovations in order to simulate returns of financial asset. The model should look like this: r_t = alpha + lambda*sqrt(h_t) + sqrt(h_t)*epsilon_t h_t = alpha0 + alpha1*epsilon_(t-1)^2 + beta1 * h_(t-1). Alpha refers to a risk-free return, lambda to the risk-premium. I've implemented it like this: #specification of the model
