Hi Pavel, As mentioned by Adrian in the comment you linked, I too am looking at DWARFv5 accelerator tables in LLVM. To give you some background: my motivation is that I want to upstream support for (Apple style) accelerator tables in llvm-dsymutil, which is currently missing because the way they are generated is slightly different. As this requires making changes the current code, I wanted to c...

Christos, We would be very interested in learning more about this. In my group, we (Prakalp Srivastava, Maria Kotsifakou and I) have been working on LLVM extensions to make it easier to target a wide range of accelerators in a heterogeneous mobile device, such as Qualcomm's Snapdragon and other APUs. Our approach has been to (a) add better abstractions of parallelism to the LLVM instruction set that can be mapped down to a wide range of parallel hardware accelerators; and (b) to develop optimizing "back-e...

...e and use cases. I am planning to share more details and a set of patches in the next days. However, I would first like to see if there is an interest for this. The project is about providing compiler and runtime support for the automatic and transparent offloading of loop or function workloads to accelerators. It is composed of the following: a) Compiler and Transformation Passes for extracting loops or functions for offloading. b) A runtime library that handles scheduling, data sharing and coherency between the host and accelerator sides. c) A modular codebase and design. Adaptors specialize the code...

Hello, i have been working with an accelerator backend. the accelerator has large vector/simd units. i want streaming loops (non-temporal) vectorized present in code to be offloaded to accelerator simd units. i find polly really suitable for this. i am thinking if the generated IR is passed to polly and then it analyzes loop to know it pos...

...hes today. I'll be sure to add everyone who expressed interest here to the phabricator diff once I have them ready. Jonas, do you have any dsymutil patches I can look at? I am interested in seeing what kind of interfaces are you using, particularly on the reading side. I think the current DWARFAcceleratorTable interface will need to be redesigned a bit if we want it to fit the dwarf5 tables as well.

In a virtualized environment running Xen or VMware, can the guest operating systems utilize hardware crypto acceleration such as the "PadLock" AES acceleration built into VIA CPUs? (Wasn't able to find this info in any of ~400 Google hits, so I'm shooting it out a bit to let as many as possible benefit from the answer.)

So ever since syzbot discovered fbcon, we have solid proof that it's full of bugs. And often the solution is to just delete code and remove features, e.g. 50145474f6ef ("fbcon: remove soft scrollback code"). Now the problem is that most modern-ish drivers really only treat fbcon as an dumb kernel console until userspace takes over, and Oops printer for some emergencies. Looking at

...or (int c0 = 0; c0 <= 2047; c0 += 1) Stmt0(c0); else { /* original code */ } there is no coincident info. Can you please explain coincident...How it is related to locality? Well my work deals with identifying non-temporal accesses and if such accesses are found offload them to my accelerator... now it can be done by multiple approaches if i implement my own pass where i do all the dependency and locality analysis from scratch using some builtin llvm passes (i dont know if they are efficient enough), so in the end my pass should detect whether the code has non temporal behavior or not....

Hello all, In <https://reviews.llvm.org/D41986#977215> it was brought up that there are at least two parties interested in having DWARF5 accelerator tables implemented, so I'm writing this email to see if there's anyone else interested in this topic, and to try to synchronize our efforts. Our interest for this stems from a desire to make dwarf parsing fast on non-apple targets (specifically android). As you may know, apple targets alre...
