How do I compile OpenSSH so that I can use: ListenAddress 0.0.0.0 in my sshd_config file ? Currently I get: [root at dark openssh-2.2.0p1]# sshd -d debug: sshd version OpenSSH_2.2.0p1 debug: Seeding random number generator debug: read DSA private key done debug: Seeding random number generator error: getnameinfo failed fatal: Cannot bind any address. if I try to use "ListenAddress

Hello, First, thanks for your help (and sorry for my english !) I have a data frame in which each row represents a vote (in percent, only 20,40, 60,80,100) of one person on one content, with three columns : name (the name of the voters), content_id, vote : str(votesredac) 'data.frame': 1000 obs. of 3 variables: $ name : chr "Guillemette Faure" "Guillemette

RFC: Inlining Report Motivation Making good inlining choices while optimizing an application is often key to achieving optimal performance. While the compiler's default inlining heuristics sometimes provide great out-of-box results, optimal performance is sometimes achieved only after varying the settings of certain compiler options related to inlining or adding "always_inline" or

Hi, Anyone knows why there's a limit of 32 callgroup/pickupgroup in * ? It is coded as unsigned int but there's an hardcoded "if( X > 31 )" like line. IMHO, 32 group is very low and I wonder what impact it would have to increase it to 2^16-1 . Anyone?

Hello! My name is Emanuel and I am an undergraduate student from Brazil (at the University of São Paulo) wanting to participate in this years GSoC on LLVM. Specifically, on the "Improve parallelism-aware analyses and optimizations" project. I currently do research on autotuning of LLVM IR optimization passes and I am sitting for a class about parallel computing, but I have been studying

Hello, in my log.nmb I regularly see these messages: process_local_master_announce: Server GUTENBERG at IP 192.168.35.90 is announcing itself as a local master browser for workgroup PIEZO and we think we are master.

Awesome, thanks! As per your suggestion, I read the description of these two projects: Advanced Heuristics for Ordering Compiler Optimization Passes Machine learning and compiler optimizations: using inter-procedural analysis to select optimizations and they are amazing! Indeed, they are very close to my interest in autotuning. I didn't see them on the list before. If I choose to focus on

During the review of https://reviews.llvm.org/D59978 we got to the question whether we can optimize based on the assumption that stack overflow is undefined behavior. While I think it is according to the C++ standard, Windows Structured Exception Handling and signal handlers might allow programs to recover/exit gracefully. Concretely, the patch D59978 wants add the noreturn attribute to functions

Let me explain to see if we agree on what the problem is. Suppose we don't artificially

Hello, I would like to build rectangles in a plot and use color and different type of hatching for filling rectangles. I don't find the way to draw hatchings. I'm thinking to build segment by segment inside each rectangle but I'm sure that exists a better way to do that. I didn't find any documentation about that. > symbols(1,1,rectangles=cbind(1,1),bg="red", ...

I have the following C source: extern unsigned int donut; void f1(); void f2(); void f1() { unsigned int *magic = &donut; if (*magic != 286529877) { f2(); } } void f2() { /* Loop here forever if application is built with wrong version of ROM image */ while(1) { ; } } The -O2 level PruneEH pass uses SimplifyFunction() which contains this code: for

Hi, All CallInsts should return true for Instruction::mayHaveSideEffects() because functions are not guaranteed to halt. Inliner::runOnSCC calls isInstructionTriviallyDead to determine whether code can be dead code eliminated. isInstructionTriviallyDead returns true if Instruction::mayHaveSideEffects() returns false. A function that potentially runs forever based on its input but does not write

Hi, I starting a new project, and have run into behavior I cannot replicate in irb, (i.e. outside of using rspec) when the directory? returns true, so I thought I''d ask here, in case any one has seen this badhavior. ruby-1.9.2-p136 rspec (2.5.0) rspec-core (2.5.1) rspec-expectations (2.5.0) rspec-mocks (2.5.0) When I try to run this spec: require Pathname(__FILE__).ascend { |d|

Hi, Building the following C code I get a call instruction that has no noreturn attribute, while the function itself does have it. void foo(void **b) { __builtin_longjmp(b, 1); } define void @_Z3fooPPv(i8** %b) noreturn nounwind uwtable { entry: %0 = bitcast i8** %b to i8* tail call void @llvm.eh.sjlj.longjmp(i8* %0)

Hi all, Recently I’ve noticed in coverage profiles that llvm_unreachable and the like are considered uncovered because there’s no special behavior in instrumentation to ‘ignore’ noreturn paths. While I don’t necessarily think it’s ideal to ignore all noreturn decls, I think there’s definitely room for some heuristics around ignoring things like llvm_unreachable (perhaps opt-in?). I’m

Hi Bill, there are a couple of things I didn't understand about your proposal, for example how it interacts with inlining, whether it is feasible to do the "turn invoke-of-Unwind_Resume into a branch" optimization and also whether in "resumedest" you still plan to use _Unwind_Resume to continue unwinding up the stack. Could you please show what the LLVM IR would look like
