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

Hello, I’m looking for the best approach which would allow for marking given LLVM IR instruction during IR custom pass and later utilizing that information during DAG Instruction Selection in order to match given pattern based on this marking. I’m wondering if marking IR instruction utilizing Metadata is good idea. But how later pass that information to DAG and appropriately mark in

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, 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,

Hi, I wrote sometime ago about this issue (see links below). http://lists.cs.uiuc.edu/pipermail/llvmdev/2015-March/084089.html http://lists.cs.uiuc.edu/pipermail/llvmdev/2015-April/084193.html At the time I thought the problem was due to a bug in my code, and that I had fixed it. But sadly it seems that the issue is still present - it just got hidden by whatever change I made. The error only

Dear all, Let say I have a sets of numbers: rno1 = rnorm(1000) rno2 = rnorm(1000) If I write request as follow: sm.density.compare (rno, rno3, xfit=min(rno), max(rno2)) why I receive a lot of curves in my plot, while I have only two data sets? regards Przemek -- View this message in context: http://r.789695.n4.nabble.com/sm-density-compare-a-lot-of-curves-tp4253039p4253039.html Sent from the

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, I am encountering a problem that I do not know how to debug. I would greatly appreciate any guidance on this issue. On Windows when I run Lua test cases from JITed code I am getting following error: Unhandled exception at 0x00007FFCEEEAC500 (ntdll.dll) in lua.exe: 0xC0000028: An invalid or unaligned stack was encountered during an unwind operation. This is happening when the Lua code is

Are you using split stacks of some kind? Are you sure these actually work as intended on Win64? Based on the source code, it looks like you are allocating stack manually, but I could be wrong. What triple are you using with LLVM to generate code? There isn't much else information here, but you can try to zero in on the problem by checking the stack alignment manually with a helper like: void

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.
