similar to: [LLVMdev] understanding DAG: node creation

Hi, Yes, that's what I would do. If you want LLVM and the register allocator to also know that the instruction explicitly defines the register, I would designate the register into it's own register class and have your instruction write to that class (and there will be only a single option for RA). cheers, Sam Sam Parker Research Student Electronic Systems Design Group Loughborough

Hi, I'm not sure. But in your lowered DAG the chain nodes are the first operands for you custom nodes, however for the other nodes the chain is the last operand. I seem to remember that during targetlowering the chain is the first operand and then it seems to switch over after ISelDAG, this confused me and may have something to do with the issue that you are seeing. I really don't

Hi all, If it's not the right place to ask, please forgive me. Currently I'm working on a new operating system concept, called "Om". The first feature would be Android-like apps, coming in *.opk files that would contain all needed resources and source-code expressed in LLVM-IR assembly language. http://sett.com/openminded-os/uid/88508 How does it sound ?

Hi Jakob, If glue operands are used by the scheduler to keep instructions together, why can't the register allocator also do this?

Hi Anitha, memri is just describing that the address contains two components, an immediate and a register, and how to handle them in the instruction printer. The STWU expects a memri operand, and that is what is passed from the Pat. Hope that helps, Sam On 07/04/2013 10:19, Anitha B Gollamudi wrote: > Hi, > > > How do "Pat" operands get matched?

Hi, How do "Pat" operands get matched? I am trying to follow the example given in http://llvm.org/docs/CodeGenerator.html#selectiondag-process In the latest trunk of ppcintrinfo.td following pattern is defined: def : Pat<(pre_store i32:$rS, iPTR:$ptrreg, iaddroff:$ptroff), (STWU $rS, iaddroff:$ptroff, $ptrreg)>; I understand that input operand list i.e. ins of

I seem to be able to lock my machine by going into wpa_cli and asking it to 'reassoc'. The reason for question mark after "hard" is that debug information (caused by wlandebug and athdebug) is being printed on the console. The only way to get machine's attention is to hold power button for 8 seconds. Note: manual reassociation is just the handy way to reproduce the problem

Hi James, So does this mean if the instruction could set the overflow flag, the instruction should not have [(set ... )] in it's pattern, i see this is the difference in instruction description for the mips case. I'm wondering how llvm knows when to use certain compare instructions such as SETNE or SETUNE? And for sign or zero extending loads? I can see the PatFrags described and the

Three different external hard drives (Seagate, Western Digital and noname USB 3.0 enclosure) refused to be recognized as the umass devices. Reverting /usr/src/sys/dev/bsd/controller to r248085, building and loading just xhci module makes drives appear again. Below are snippets from the log in both cases: Non working: Jul 4 14:35:17 twinhead kernel: xhci0: <XHCI (generic) USB 3.0

Hi Everyone, I have an llvm project from which I am trying to call external libraries such as boost. For some reason, when I type make, llvm can't seem to find the header files to the library even though it's in the path. I am baffled by this. For example, for boost this is what I get: " fatal error: 'boost/lambda/lambda.hpp' file not found" Do I have to modify

David Schultz, in his spare time, has been working through some of the issues I've been able to 'tweak' in the unionfs code ... as he is currently working on forward-patching it to -CURRENT right now, he can't commit the code to the -STABLE tree ... in order to allow others using unionfs to test the patch (I've been running it a few weeks now on a very heavily

Sorry if this isn't the right place to ask this question. I'm thinking of writing a module that intercepts Samba requests to keep only a subset of a file store on a local server with the rest being stored on a cloud.  It would be an open source module similar to these products: https://aws.amazon.com/storagegateway/

Hello everybody! Since the update from 6.2-STABLE to 7.0 I'm encountering problems with the temperature of my Thinkpad X60s. Under heavy load, e.g., make builworld or compile gcc or...

Hi everyone, I was wondering if anyone on this group has successfully integrated Avaya 8300 or 8700 and Asterisk using H.323 trunk and would be willing to share configurations and/or comment on the voice quality achieved. Currently we have Avaya 8300 integrated with Asterisk over a Q.SIG trunk, but we need to put Asterisk in a different geographical location from the PBX and need to explore
