...x86_subreg_32bit)>; This isn't currently being reflected in the InstrInfo tables. Naively, it seems like we should add a separate INSERT_SUBREGrm instruction, and so on, or something like that, in order to be able to have accurate InstrInfo tables. Does anyone familiar with the new subregs infastructure have an opinion on this? Dan

Most backends use the SelectionDAG infastructure to do this kind of thing. (Simplifying things a bit) Each basic block is selected to a DAG based IR. Then instruction selection is done, which transforms this DAG to a DAG with machine instructions as nodes. At this point all dependencies are explicit as edges in the graph. The DAG is then sch...

why there is no general dependency analysis for the "machin code"? perhaps it's because the instruction scheduling is only implemented for sparcv9? i am going to implement a dependency analysis pass for machine code block. the result will be returned in a boost graph (http://www.boost.org/libs/graph/doc/table_of_contents.html). just to check if it has already been implemented. it

...forum for this question but I am looking for people with some ideas on networking generally and since I am evaluating tinc this seems like a good place. We are a very small comany who rent out managed servers, which are linked to the Internet via a variety of means, mainly ISDN links. We have two infastructure servers co-located. Each client site has one (or more) of our servers on the premesis. Some of out clients also do vpn between themselves (which our servers have to handle) and pptp dialins (which go to the infastructure servers and are routed appropriately) For example purposes I will describe...

...t statically do these optimizations profitiably, and even profiling may blur the fact that the call is mostly static (since different input data may generate different call targets). Thus you must do runtime profiling and JITing. Granted, LLVM currently doesn't really do much of this, but the infastructure is there to do so. Andrew

Right, but you can get this by doing profile directed optimisation during development so end users/production systems don't have the overhead. Also it seems to me that at some point the bookkeeping and analysis overhead for these optimisations would reduce performance of th...

...you recommend it for use in a heavy use type environment? I've noticed in the README for this there's identifiers for "logoff time" and "kickoff time". Hmm. Basically, the clients are Windows XP machines, and previously I had written a Windows client / UNIX server infastructure to do this logging off. Can samba actually "kick" users off after a certain amount of time? Wow. If it can, someone let me know how :) R

I guess this is slightly offtopic, but the post about the JIT and garbage collection made me wonder why LLVM supports JIT compilation at all. It has much smaller scope for optimisation due to the speed requirements, takes more memory and causes the same work to be repeated over and over for each execution. What reason is there for anything to use JIT compilation over ahead-of-time compiling to

It depends on what aspect of LLVA you are refering to, and whether you mean LLVM or LLVA. LLVM is the Low Level Virtual Machine (a compiler infastructure). The LLVM tools will run on most UNIX platforms (I believe there is some support for Windows as well). The LLVM JIT and static code generators support x86, Sparc, and PowerPC, and there is some support for Itanium and Alpha. There is also a C-Backend which allows LLVM to generate native c...

Hi, I'm trying to compile linux kernel with llvm to generate llvm ir (bitcode). It seems like llvm-ld doesn't accept any linker scripts. How do I deal with vmlinux.lds in such a case? How did people who have compiled linux kernel with llvm deal with this in the past? Thanks, Ashish

I'd like to get some runtime profile data on my code using LLVM. The various -insert-X-profiling passes seem to add the profiling instrumentation to the code, but how do I actually generate profiling output? It seems like utils/profile.pl can do this, but it uses profile_rt.so which doesn't exist. I can manually compile the runtime directory using make install-bytecode, but it

...om the bitcode. By the way, it you are still planning on jitting the kernel, you should be warned that the linker script creates globals and arrays that are referenced by the kernel code but otherwise will appear nowhere in your bitcode... You will have to rewrite the kernel's initialization infastructure or write a pass to fix up the bitcode or both. Andrew ====================================== As an experiment, I've tried using llc to convert the vmlinux.bc output into native assembly, then use "as" and "ld" to produce a native vmlinux, but the ld step fails with: ld:...
