In particular,

Sounds good. Lets get started by nailing down the C API and semantics for this first. I mirrored the C API for the LLVM context diagnostic handler and used Andy’s suggested name for the callback. The opaque handle was suggested by Duncan and can provide optional user specified information that is provided back during the callback (i.e. barrier, etc). Cheers, Juergen Core.h: typedef void

I have a Module/LLVMContext that I'd like to clone and manipulate in different threads (each thread may perform different translation / optimization, so they need unique copies). Currently this process has to be locked, since each clone of the Module still refers to the same LLVMContext. Is there a way to clone both the Module and LLVMContext so that the copies can be manipulated

You could probably round trip it through bitcode in memory. I think all of the IR cloning functionality assumes that only one context is being used. Even if the serialization isn't efficient as a clone could be, it should give you very high confidence that everything Just Works. :) On Tue, Jun 18, 2013 at 1:16 PM, Andrew Clinton <andrew at sidefx.com> wrote: > I have a

Sorry to resurrect an old thread, but I finally got around to testing this approach (round tripping through bitcode in memory) and it works beautifully - and isn't that much slower than cloning. I have noticed however that the copy process isn't thread-safe. The problem is that in Function, there is lazy initialization code for arguments: void CheckLazyArguments() const { if

Hi, I have longitudinal school suspension data on students. I would like to figure out how many students (id_r) have no suspensions (sus), i.e. have a code of '0'. My data is in long format and the first 20 records look like the following: > suslm[1:20,c(1,7)] id_r sus 11 0 15 10 16 0 18 0 19 0 19 0 20 0 21 0 21 0 22 0 24 0 24

You have to have a system running for more than 65 minutes for it to run the daily cron jobs. And if this is a test system that you keep rebooting. Well. So if I want /var/log/rpmpkgs to get updated, I have to wait until the next day an keep the system up for a bit more than 65 minutes. Actually a quite reasonable requirement. Add this to my 'book': cron is your friend. Anacron

Hey, I thought there was supposed to be an ability for domU''s to be put into a hibernated state (E.g. current running tasks and memory) when dom0 is shutdown or rebooted. When I look in my /etc/default/xendomains file, I have the variable''s "XENDOMAINS_SAVE=/var/lib/xen/save" and "XENDOMAINS_RESTORE=true". However, when I reboot, I always have to restart my

TL;DR ==== This RFC suggests an API to enable customizable instrumentation of pass execution. The intent is to have a common machinery to implement all the pass-execution-debugging features mentioned here. Prime target of the interface is the new pass manager. The overall approach and most of the implementation details should be equially applicable to the legacy one though. Background

Hi, I have a big problem. I see that samba 4 don't have bad lockout attempts and if samba don't have this, I cannot deploy samba 4. This setting is a security setting, it's very important. A virus attack can be modered by this setting (password crack) and the security bookfor IS from my compagny says : 11.1.3 User password management 11.1.3.1 Recommendations for access

I computed "system.time(diag(30000))" with R 2.12.0 on Fedora 13 Linux with 4 GB RAM and with R 2.14.1 on Windows 7 with 8 GB RAM: Linux (4 GB RAM): 0, 0.21, 0.21 -- a fifth of a second Windows 7 (8 GB RAM): 11.37 7.47 93.19 -- over 1.5 minutes. Moreover, during most of that time, I could not switch windows or get any response from the system. When I first encountered this, I

Care to expand a bit on what you mean by per-optimization level? Preferably with a use case. To me optbisect is a low level developer tool and it doesn't cope well with a crude user level hammer of optimization level. F.
