Hi, for DAG-to-DAG instruction selection I’ve implemented a pattern, which creates from one SDNode two instructions, something like: def: Pat<(NEW_SDNODE REG:$r1), (INST_OUT (INST_IN), REG:$r1)>; where INST_IN doesn't accepts any inputs and INST_OUT accepts two inputs - one returned by INST_IN and REG;$r1. Is there any possibility to ‘Glue’ two instruction created

You could hardcode a register for the pseudo instruction to use in the td file. The register allocator will make sure not to clobber it. let uses = [ R1 ], defs = [ R1 ] in { def MYINST : Pseudo<> } On Wed, Dec 11, 2019 at 10:25 AM Przemyslaw Ossowski via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > I have one more question regarding expanding pseudo instruction. > >

Thank you Craig for explanation. Could be the same algorithm used for custom legalizing given node in LowerOperation and ReplaceNodeResults in case results and inputs of the node are illegal? Or actually such situation is impossible and for given node either LowerOperation or ReplaceNodeResults can be only called? Przemek wt., 28 sty 2020, 18:48 użytkownik Craig Topper <craig.topper at

Hi, I see that for different targets in classes which inherits from TargetLowering there are implemented both methods: LowerOperation and ReplaceNodeResults What decides that for one given ISD we have to add handling in LowerOperation and for other in ReplaceNodeResults, when for both SetOperationAction is configured to be Custom? Is it related with number of results of given operation and

Hi all, my question is maybe not directly related with LLVM but general with compilers. The common approach is that compilers often don't align stack pointer for leaf functions if the function utilizes stack just for keeping variables of small sizes. I’m wondering what is the benefit of such behavior. Is saving a few bytes of the stack just once worth of such approach? Or maybe

Hi, I am posting my question to both storage-discuss and zfs-discuss as I am not quite sure what is causing the messages I am receiving. I have recently migrated my zfs volume from b104 to b134 and upgraded it from zfs version 14 to 22. It consist of two zvol''s ''vol01/zvol01'' and ''vol01/zvol02''. During zpool import I am getting a non-zero exit code,

I'm trying to 'lower' an operation that needs to create a node in the SD that is an intrinsic call.... what is the best way to do this? I see in the DAGBuilder it calls 'setValue' which adds to the map NodeMap[V] where V is the key and the passed in SDValue is the value but I'm not sure this is a good way to do it since these are local to SelectionDAGBuilder and the

Hi, I'm a teacher and I have got 20 computers with Windows XP and server Windows SBS 2003 with Active Directory. I use AD to set policy tu WinXP and to authorize users. Is it possible to set up Samba to this instead AD? Can someone help me in this? -- Przemyslaw Adam Smiejek

Hi This is my first post here so i will be as precise as i can I'm trying to setup a quota system using dovecot postfix and procmail dovecot version 1.2.9 postfix version 2.7.0 I have succesfully modified dovecot config to use fs quota system (so far imap and pop3) It reports correct quotas to imap and pop3 clients (both user and group) What im tryin to do now is to modify

Hi, How can I get the llvm-type of the formal argument while lowering it ? My target needs to map pointer and non-pointer parameters to different registers. In addition, parameter lowering is address space dependent (another reason why I need such information). Looking at the DAGBuilder, I found that it is dropping it when translating llvm-types to BE types. Even if the base type is saved

Hi Im using Dovecot 1.0.10 and everything seems work ok except one client He is accessing his mailbox using iPhone There are several custom folders created and mail is directed to them using procmail The problem is iPhone mail app only sees changes in INBOX and when new mail arrives to other folders it will not see it unlers user accesses this particular folder Is there some kind of workaround

Under MacOS I had R64 executive and it was clear. Under Ubuntu, which I do not have administrative rights to, there is only R executive. It seems that I can allocate more than 3GB of memory, however not everything seems to work the same/right as with R64 under MacOS. Pms.

Hi, I'm looking for a solution to access pop mails (sendmail in linux) securely. Most of the access would be from window clients (outlook express etc). Is there a way to encrypt the password (like ssh2) when authenticating with sendmail? Any info is greatly appereceiated. Thx. Regards, Wong.

Hi! I'm quite new to Dovecot. helping my friend to migrate from Courier-IMAP to something more efficient, we are evaluating Dovecot at the moment. I had to prepare 2 small patches for Dovecot to suit our needs, and I've decided to post it here. I'm not fully familiar with Dovecot architecture yet, I'd appreciate if someone could look if these changes make sense (i.e.

Hi, In the directory of lib/CodeGen/SelectionDAG, I cann't find SelectionDAGISel.cpp. I only have DAGBuilder.cpp and SelectionDAG.cpp. I don't know why. My edtion is 1.4.

If you need llvm::Argument, this returns the iterator pointing to the first argument: Function::const_arg_iterator Arg = DAG.getMachineFunction().getFunction()->arg_begin(); On Wed, Mar 14, 2012 at 8:16 AM, Ivan Llopard <ivanllopard at gmail.com> wrote: > Hi, > > How can I get the llvm-type of the formal argument while lowering it ? > > My target needs to map pointer and
