Hi all, My understanding is that we keep around KILL instructions in order to keep the results of the various register liveness analysis passes valid. Consider for example the following machine basic block: BB#0: derived from LLVM BB %entry Live Ins: %A0_64 %A1_64 %V0_64<def> = AND64 %A0_64<kill>, %A1_64<kill> %V0<def> = KILL %V0, %V0_64<imp-use,kill> PseudoReturn64 %RA_64 In this case we would like to move the AND64 instruction after the KILL instruction (generated from an identity COPY). What is the right thing to do with the KILL ins...

Hello, About a month ago, I submitted a set of patches for review on llvm-commit. The most controversial of the patches, http://lists.cs.uiuc.edu/pipermail/llvm-commits/attachments/20150622/d104ea7 1/attachment-0009.obj deals with the fact that before ARMv8, the rGPR RegClass in Thumb encodings didn't include SP; but from ARMv8 onwards, it does include it. RegClass membership is

Hello, Not sure this is the right place to ask Xen user-questions. I am running Lenny and try to upgrade a domU to Squeeze. After the installation of a new xen-kernel in the domU and upgrading udev I did a reboot but then the kernel does not find the root anymore, and it's dropping me to a shell. When I look into /dev/ I don't see any disks or partions. Is here somebody who can help me

...nt that r235869 (http://llvm.org/viewvc/llvm-project?view=revision&revision=235869) is the cause of this regression. The problem is these three definitions: // Bypass trunc nodes for bitwise ops. def : MipsPat<(i32 (trunc (and GPR64:$lhs, GPR64:$rhs))), (EXTRACT_SUBREG (AND64 GPR64:$lhs, GPR64:$rhs), sub_32)>; def : MipsPat<(i32 (trunc (or GPR64:$lhs, GPR64:$rhs))), (EXTRACT_SUBREG (OR64 GPR64:$lhs, GPR64:$rhs), sub_32)>; def : MipsPat<(i32 (trunc (xor GPR64:$lhs, GPR64:$rhs))), (EXTRACT_SUBREG (XOR64 GPR64:$lhs, GPR64:$rh...

Hi, I have tagged the 3.6.1-rc1 so testing can begin. We can always use more testers, so if you are interested in helping, let me know. Instructions for validating an LLVM release can be found here: http://llvm.org/docs/ReleaseProcess.html Reminder: We are using 3.6.0 as our baseline for regression testing. Thanks, Tom
