similar to: __syncthreads() inrtinsic seems to be missing from __clang_cuda_device_functions.h

Hi Justin, Is a compiler allowed to inline a function that calls __syncthreads? I saw nvcc does that, but not sure it's valid though. For example, void foo() { __syncthreads(); } if (threadIdx.x % 2 == 0) { ... foo(); } else { ... foo(); } Before inlining, all threads meet at one __syncthreads(). After inlining if (threadIdx.x % 2 == 0) { ... __syncthreads(); } else { ...

I'm using 7.0. I am attaching the reduced example. nvcc sync.cu -arch=sm_35 -ptx gives // .globl _Z3foov .visible .entry _Z3foov( ) { .reg .pred %p<2>; .reg .s32 %r<3>; mov.u32 %r1, %tid.x; and.b32 %r2, %r1, 1; setp.eq.b32 %p1, %r2, 1; @!%p1 bra BB7_2; bra.uni

Hi, I wanted to ask whether there is ongoing effort (or an already established tool) that enables to convert CUDA kernels (that uses CUDA specific intrinsics, e.g., threadId.x, __syncthreads(), ...) to LLVM IR. I am aware that I can do this for OpenCL with the help of libclc but I can not find something similar for CUDA. Thanks -------------- next part -------------- An HTML attachment was

Justins: I noticed that the intrinsics in IntrinsicsNVVM don't specify a TargetPrefix. This seems like a simple omission, so I was going to simply throw a `let TargetPrefix = "nvvm" ` block around them, but this doesn't quite work. There seem to be three prefixes that are used in this file. About 900 are int_nvvm_*, 30 are int_ptx_*, and 1 is int_cuda. It isn't clear to me

Hi Jingyue, Convergent is not intended to prevent inlining. It’s tricky to formalize this inter-procedurally, but the intended interpretation is that a convergent operation cannot be move either into or out of a conditionally executed region. Normal inlining would not violate that. I would imagine that it would make sense to use a combination of convergent and noduplicate for barrier-like

By the way, I've been using the existing read-only monorepo [1] for a few days now. The intent is to commit via the script I put together [2], although I haven't committed anything other than a testing commit [3]. All I can say is, *wow* is it nice. I hid everything I don't care about using a sparse checkout [4]. Many of my tools (e.g. ctrl-p [5] [6], ycm [7]) suddenly work better

> And if it is, then the "only thing a monorepo gets you" isn't something that you need a monorepo to get. This is an *extremely important* point to understand, so let me try to be really clear about the current state of the world and the state of the world under the two "move to git" proposals. Today, all commits ultimately end up in SVN. Our SVN is a effectively a

Hi Mehdi, My reading of it is that if you have a convergent instruction A, it is legal to duplicate it to instruction B if (assuming B is after A in program flow) A dominates B and B post-dominates A.

Okay, I just bumped into r277008, in which commits to llvm, clang, and clang-tools-extra all have the same SVN revision number. I don't

I have written test.ll as below and ran 'opt' on it as " opt -std-compile-opts test.ll -S -o -" . But the output shows that there is code motion around the barrier intrinsics. test.ll ------- ; ModuleID = 'test.bc' define void @test(i16* %I_0, i16* %I_1, i16* %I_2, i16* %I_3, i16* %O_0) { entry: %T_0 = load volatile i16* %I_0 %T_1 = load volatile i16* %I_1 %T_2 =

Dear list, I have a table with entries for 20 animals - x and y coordinates to analyze movement with the package adehabitat. The package does all the necessary analyses, but I need to create an object of class ltraj for each animal first. For this kind of object I need to define xy coordinates, id, and few other things for each individual. Now I don't want to run a code 20 times

Hello all! (cc-ing the flac-dev list) I would like to give an update as to the recent CELLAR work on the FLAC specification. • Work has been done to make internal and external links more accurate and reliable. • 'Rice Coding' has been clarified as 'Exponential Golomb Coding.' • Clarifications have been made for binary representation. • Typos and other small changes have been
