similar to: [LLVMdev] C++ to C?

Hi Duncan,   Thanks again for your reply.   Yes, I am interested in the interpreter, but perhaps I misunderstand what LLVM is...   My assumption has been that LLVM generates machine code for a virtual machine, and that you supply an interpreter that will execute the code.   I'm interested in this from an educational standpoint. What I'd like is a C/C++ compiler that generates machine code

LLVM is a lot of things, the web page gives some important areas (http://llvm.org/).

Hi Daniel,   Thanks for your help.   You mentioned that "the current interpreter makes no pretense of running on a "virtual machine"", but isn't the interpreter itself a virtual machine? I'm not looking to emulate any particular processor - just interested in a tool that will help teach how a processor works.   Can LLVM help, or am I completely off track?   Thanks, M.

I realized I missed this part of your email: Can LLVM help, or am I completely off track? > It isn't clear to me yet. I have used LLVM for a different but similar purpose, which effectively implements a stronger virtual machine on top of the LLVM IR. I have been very happy with the decision to use LLVM instead of, say, working with x86 directly. On the other hand, if you are only

I think LLVM is capable of what you're asking, but it isn't really a goal of the project, and thus might require you to put in a fair amount of work yourself to get there. LLVM is targeted much more at the compiler side of things...it makes a great educational tool in that domain, but the virtual instruction set is tailored more to the needs of compiler front-ends, optimizers, and code

Daniel,   Thanks for the reference to SPIM. It looks interesting, but appears to be an assembler that can also execute the code (it does not execute binary files). In addition, I'm probably asking for too much. Ideally, I'm looking for something like MS Visual Studio with that executes on a virtual software machine, whose source code is freely available.   Thanks, M. McDonnell --- On

HPA, now that syslinux release madness has calmed down, could you provide some info on how we syslinux-minions/wannabes can use bochs and/or qemu to run (sys|pxe|iso|ext)linux in an emulated environment thats more conducive to debugging, single-stepping, and ultimately understanding how the magic happens ? tia jimc

Hi, I''m new to Ruby on Rails and am having a little difficulty working through the ''Rolling with Ruby on Rails'' tutorial. Can anyone help? I''m trying to get the cookbook application to work via a Postgresql db. But get the following error when trying to access http://127.0.0.1:3000/recipe/new Errno::EINVAL in RecipeController#new Invalid argument

Hi there, I can''t upgrade rspec on rails to 0.7.5.1. I followed the install guide on the website without sucsess. Here''s my env info: $ rails -v Rails 1.2.2 $ gem -v 0.9.2 $ spec -v RSpec-0.7.5.1 (r1395) - BDD for Ruby http://rspec.rubyforge.org/ $ spec ... <snip> ############################################################################ Your RSpec on Rails plugin

For those interested .... rake spec:models seems to clone the test database from development. If your dev db is empty, the models task fails mysteriously. Anyway, to make sure your dev db is at the current migration version, I added this dependency in lib/tasks task ''spec:models'' => ''db:migrate'' Now the dev db is migrated up with each test pass.

Hi there, Is it just me or do many other rspec / rpsec_on_rails users spend more time than they would like feeding the framework ? Don''t get me wrong, I love rpsec, but I seem to spend about 2/3 hours per week hunting down rspec problems. For example, today `rake spec:models` is broken. When I migrate, load fixtures and run `spec -cfs` all is well. When I run `rake spec:models`,

I''d like to use a frameset to separate the content in an app I''m playing with into 3 separate panes. A 1/3 page width left pane will be for general navigation, (so rarely needs reloading). The main content separates into a top and bottom pane, (with the top pane being set by the nav pane, and the bottom pane being set by the top pane). Unfortunately, I''m new to

Hello, I am trying to write a function that first requires randomly sampling items from a set of factors. I need to be able to sample from that same set of factors, but exclude the ones that have already been sampled previously. For example, suppose I have a set of items a-j (a,b,c,d,e,f,g,h,i, and j) and randomly sample a, c, and f from that group. How do I sample again from the larger group

Hi! I'd like to play with snes, arcade and other retro games, but unfortunatelly there isn't any linux emus for this. So I run the emutaltor callus with wine, with medius succes: Callus works fine, everything is ok, but it uses 100% CPU, and becouse of that, the soung goes wrongs somethimes. I don't know why it is takes so mutch work to wine... Callus emulate only 66 Mhz... The

The driver doesn't consider framebuffer pitch and offset, leading to a wrong display in case offset != 0 or pitch != width * bpp. Fix it.

Hi there, I have a *really* weird issue with rspec on rails: Given a time meridian formatted using %p When I run `rake spec` the time meridian is converted to lower case: expected: "Today 08:00 PM", got: "Today 08:00 pm" Yet when I run `rake spec:models` and `spec -cfs app/models` the specs pass, ie the the time meridian is in upper case. Anyone got any ideas how I

If bo->width doesn't match fb->width the driver fails to configure the display correctly, resulting in a scrambled display. Fix it.
