Hello, i mainly code in c/c++ on linux. I would like to know if I can generate code at runtime using llvm, like libgccjit -> https://gcc.gnu.org/onlinedocs/jit/ My needs are : create functions, conditions, loops at runtime. libgccjit does the job pretty well but I would like to test llvm too (licence issue). Is it possible ? Is there a resource that helps in that regard ? Kaleidoscope

This set of patches converts the way frames gets created from using PUSHes/POPs to using MOVes, thus allowing (in certain cases) to avoid saving/restoring part of the register set. While the place where the (small) win from this comes from varies between CPUs, the net effect is a 1 to 2% reduction on a combined interruption entry and exit when the full state save can be avoided. 1: use MOV

Team, I''m trying to figure out how to run 2 rails apps on one host. I ran an experiment: cd /tmp/ rails app1 rails app2 cd app1 script/server rails put a copy of lighttpd.conf in /tmp/app1/config/ and then started lighttpd http://localhost:3000 gave me the splash page. I shutdown the server I added something to /tmp/app1/config/lighttpd.conf server.modules = (

I just finished updating our internal site, which hosts multiple Rails apps, to Apache 2.2.3. It also has a TWiki rewritten into the root, ViewVC mounted on /cvs, and /server-status and /server-info. <VirtualHost *:80> ServerName int.example.com ServerAlias int CustomLog /var/www/logs/int.example.com/access.log combined ErrorLog /var/www/logs/int.example.com/error.log [...]

Hi all, I am facing a problem while using rails "migrate" feature for creating tables in a database. Following are the details. I have 2 applications say "app1" & "app2". I want both of them to use same database say "testdb". For "app1", I create 3 models which in turn create 3 migration files with prefix, 001_, 002_ & 003_. Now I

hey all, I have an app working great with apache2 and mongrel_cluster. However, I''m trying to run another application and now when I go to app1.comit falls to app2.com and the opposite. That''s probably because I messed up somewhere with the cluster. this is the content of my conf.d/app1.proxy_cluster.conf: <Proxy balancer://mongrel_cluster> BalancerMember

Hi i have 2 seperate rails applications. They both share the same login system. If someone is logged into application 1 then they should be able to start using application 2 without logging in again. I am unsure how to achieve this. I''ve a feeling i can somehow do it by telling both the apps to share a cookie, but i''m not sure. Does anyone know how to do this or has anyone

I''m trying to set up several different Rails apps on the same domain, each one running Mongrel. After reading all of the documentation, it''s fairly clear how to use subdomains - create several Apache virtual hosts, each of which has a different ProxyPass and ProxyPassReverse command to redirect from different ports (ie, 3000, 3100), and then have each Mongrel instance (or

Hi, just a quick question, is there a way how to run two apps on the same domain? Both for testing purposes. Thank you.

I am using the ssh port forwarding feature. My configuration is as follows: On my server machine, running sshd, and app1. On my client machine, running ssh (client) and app2. The client connects to the server requesting remote port forwarding from port X on the server machine to port Y on the client machine. app2 is listening on port Y on the client machine. app1 connects to port X

I''m trying to use create_resources to create a series of files with semi-custom content based on a template.

Hi There, I am currently exploring C++ JIT-compilation for a project where this would be very useful. I started with the code from the lli tool which uses OrcLazyJIT and changed it, such that the module is being compiled from c++ source in memory and OrcLazyJIT is used exclusively. Now since I am on windows, I found that my application is crashing when trying to run the main function from the

Hi David, This is really cool. I'd love to get this in-tree. There are two ways we could go about this: (1) Make the OrcArchitecture interface ABI-aware so that it can choose the right resolver code, or (2) Replace the OrcArchitecture classes with OrcABI classes. I.e. We'd just a rename OrcX86_64 -> Orc_X86_64_SysV (and rename I386 & AArch64 similarly) , then we add your code as

I am wanting to one run instance of lighttpd, many many instances of mongrel. I also need ssl but only for one of my sites. I understand that Mongrel does not play with SSL so I am forced to use Lighttpd. I think that lighttpd only handles ssl or non-ssl on any given instance. Is there a way for me to accomplish my goal of one lighttpd with multiple mongrels and the occasional ssl connection? --

Agree with Duncan on including associative operation too.

Hello LLVM Community, To improve Interprocedural Register Allocation (IPRA) we are trying to force caller saved registers for local functions (which has likage type local). To achive it I have modified TargetFrameLowering::determineCalleeSaves() to return early for function which satisfies if (F->hasLocalLinkage() && !F->hasAddressTaken()) and also reflecting the fact that for local

According to this http://llvm.org/docs/CodeGenerator.html#tail-call-section, it seems that adding a new CC for the purpose of local function optimization seems a good idea because tail call optimization only takes place when both caller and callee have fastcc or GHC or HiPE calling convention. -Vivek On Sun, Jun 26, 2016 at 1:26 AM, vivek pandya <vivekvpandya at gmail.com> wrote: >
