Hello Leslie, I think we are going to need to know a bit more about the ELF ABI for what looks like the ArcCompact before we can help you. LLD's calculation of P (the place to be relocated) is as it is in the generic ELF specification. The Rel.Offset corresponds to the ELF r_offset field. This is covered by: "For a relocatable file, the value is the byte offset from the beginning of the section...

Hello Leslie, I don't know quite what to say as I don't know precisely what your question is? If I am not being precise enough please can you put some explicit questions in? From what I can see in the output, here are some comments. >From your arc mapfiles it looks like that in the output both linker's have given the .text output section the correct base address given the alignment restrictions as the alignment requirement of .text from lib_a-memset-bs.o is 4, therefor the alignment requirement of the OutputSection .text should be 4: LLD...

Running an mmap-intensive workload on ZFS on a X4500, Solaris 10 11/06 (update 3). All file IO is mmap(file), read memory segment, unmap, close. Tweaked the arc size down via mdb to 1GB. I used that value because c_min was also 1GB, and I was not sure if c_max could be larger than c_min....Anyway, I set c_max to 1GB.

Hello everyone, I'm trying to compile my test.cpp for ARC, using this guide https://clang.llvm.org/docs/CrossCompilation.html. I've built my LLVM+CLANG with ARC, ARM and X86. clang -target arc -S test.cpp Gives me: error: unknown target triple 'arc', please use -triple or -arch clang -targer arm works fine Is there any way to compile for A...

Hi Pete, Thanks for your kind response! I migrated AVR target for lld https://reviews.llvm.org/D32991 it is very beginning, only support R_AVR_CALL reloc, and ARC is more complex than AVR, I will learn it from binutils, also ARC related doc, then try to implement it. 发自我的iPhone ------------------ Original ------------------ From: Pete Couperus <Peter.J.Couperus at synopsys.com> Date: 周五,9月 1,2017 11:17 下午 To: Leslie Zhai <lesliezhai at llvm.org.c...

Here's the situation: Some of our users runs Windows XP with ArcView GIS 3.3 by ESRI. In this application, ArcView is used to render some scientific data which is stored in files on a Samba server.

We should , as a follow-up patch, embed the encoder in arcgpu_drm_private. Then we drop the kzalloc() and avoid that life-time challenge. This patch looks good for what it does. Acked-by: S...

Oh, that's what I was afraid of. So there is definetly no way to compile for ARC? If so, should I write ARC.h(.cpp) in lib/Basic/Targets in order to make it work? чт, 27 сент. 2018 г. в 14:47, Tim Northover <t.p.northover at gmail.com>: > Hi, > > On Thu, 27 Sep 2018 at 12:41, Павел Безбородов via llvm-dev > <llvm-dev at lists.llvm.org> wrote: > >...

One thing I''ve been confused about for a long time is the relationship between ZFS, the ARC, and the page cache. We have an application that''s a quasi-database. It reads files by mmap()ing them. (writes are done via write()). We''re talking 100TB of data in files that are 100k->50G in size (the files have headers to tell the app what segment to map, so mapped chunks...

Hi all, The Phabricator docs seem to say that downloading a patch goes with `arc patch`. However, I tried it on several revisions and they all fail with: Checking patch some/path/to/a/file/that/exists ... error: some/path/to/a/file/that/exists: does not exist in index With the svn repo I found that command to be really useful. But now it seems like I have to download the patc...

Would someone "in the know" be willing to write up (preferably blog) definitive definitions/explanations of all the arcstats provided via kstat? I''m struggling with proper interpretation of certain values, namely "p", "memory_throttle_count", and the mru/mfu+ghost hit vs demand/prefetch hit counters. I think I''ve got it figured out, but I''d really like expert clarific...

Hi, Please forgive me if my searching-fu has failed me in this case, but I''ve been unable to find any information on how people are going about monitoring and alerting regarding memory usage on Solaris hosts using ZFS. The problem is not that the ZFS ARC is using up the memory, but that the script Nagios is using to chec...
