Guidance on working with the NVIDIA GPU back-end
Hi all, I'm primarily a hardware person but would like to do some compiler-architecture co-design research. Are there any good references for the NVPTX backend? I'd like to change that backend to have a limited number of physical registers rather than an unlimited number of virtual ones (for more realistic modeling in a uarch simulator). Being able to do register allocation and other

[RFC] carry-less multiplication instruction
(As per IRC discussion) I understand that the carry-less multiplication algorithm has it's uses since/and it is implemented as an instruction in many architectures and that adding it as a general-purpose intrinsic will allow us to drop target-specific intrinsics as by-product. What i do *NOT* understand is: what is the actual/main goal/driving factor of adding an LLVM intrinsic for it? The

[LLVMdev] Two Regalloc Enhancements
We have two features for register allocation we'd like to contribute if folks think they are worthwhile. We want to get a read on whether they will be useful to people. The first features backschedules reloads during the spilling phase. As reloads are generated, we have some very simple code to try to schedule them as far ahead of the use as possible. The second features modifies

[PATCH 0/5] btrfs: lz4/lz4hc compression
WARNING: This is not compatible with the previous lz4 patchset. If you''re using experimental compression that isn''t in mainline kernels, be prepared to backup and restore or decompress before upgrading, and have backups in case it eats data (which appears not to be a problem any more, but has been during development). These patches add lz4 and lz4hc compression
