I've been tossing around some ideas about high-level backends. Say, have LLVM emit Perl code. Sounds whacky but isn't. It's good for the first bootstrapping phase in environments where you don't have a C compiler, where you don't have a cross-compiled binary for download, but you can execute Perl. It also makes a great inspect-the-sources-with-an-editor stage for aspiring

Hi Nate, I've successfully ported one bitcode from Linux to Mac to Windows.  All were x86 and the program was text-based, but I'd say my LLVM Wrapper would be worth some effort in the future if I could just get some help.  Currently it just wraps StdIO.h with its own functions. Here's some of what it would take to make portable bitcodes in C or LLVM Assembly: * Convert all

What benefit do you get from having a backend here rather than an interpreter for LLVM IR?

The same thing as an interpreter, just a native build (no need for an interpreter program, better speed, etc). This would be beneficial anywhere that "build once, deploy anywhere" functionality is desired, without resorting to using a higher-level language like C# or

A backend that's self-sufficient and covers the entire Unixoid world. That cuts down on the number of binaries that one needs to provide for autoinstallers and such. Generated Perl could be used to bootstrap an LLVM IR interpreter, for example.

Hi there, I'm having an issue with vbscript in wine. It relates to a problem with the cardbox database client which you can see here: http://www.cardbox.com/wine.htm I get the Cardbox error message and pressing OK will return me to the Cardbox window, indicating vbscript is not installed. First I just ran the installer which I found here:

Hi all, using * 1.2.9.1 and this week all of the sudden calls keep ringing even after they've been picked up... Here's one users summary: When I pick up the phone, I hear a dial tone and I am able to dial out. But for some odd reason, the receiving line picks up while the outgoing line is still ringing. And the receiving line can hear everything while the phone is still ringing. I tested

* Is there a way to configure NUT so that it recognizes the huge additional battery pack that has been attached to the 2200XL? The 51minutes runtime is a number consistent with the load we have placed on a stock standalone 2200XL. With the extra large battery pack we've added, the runtime should be more than 2.5 hours. * I see the "Bizzare configuration" graphic on the

Just a (probably crazy) thought: What about porting Windoze apps that aren't written in C? I've got a Delphi application that currently runs under Virtual PC under OS 9.2 on an eMac (PPC Processor), which would run much faster without those OS layers in between. I don't really have a clue as to whether this really far-out-whacky or not cuz I am not really a Delphi, or, for that matter,
