Is it possible to write LLVM IR but not using C++? I'm exceedingly terrible at C++. I was thinking, isn't it possible to write the IR using Java? I effectively have emit some sort of binary op codes to be passed into llvm right? The same thing for if I wanted to integrate a GC? Could the interfacing be done in any other language? -------------- next part -------------- An HTML

I generally see an announcement on the list for the social events .. but I haven't seen one yet for June. It will be my first social if we're having this. -------------- next part -------------- An HTML attachment was scrubbed...

Seems like a new change in LLVM has made it so that bitcast of bitcast i8* %1 to %Foo* meaningless? If I'm correct is there any need for the bitcast anymore? -------------- next part -------------- An HTML attachment was scrubbed...

I recently saw a post about being able to call LLVM APIs from .NET using a C# library. I'm thinking if it'll produce the same code as using the LLVM C++ API. Will it be less efficient? If it is the same why wouldn't every one use a higher level language like C# or Java to write their compiler? -------------- next part -------------- An HTML attachment was scrubbed... URL:

Here is some IR that is working and executing as expected -- All allocas are in the first basic block, and only updates happen in other basic blocks. define i32 @f() { entry: %x = alloca i32 store i32 333, i32* %x %i = alloca i32 store i32 11, i32* %i br i1 true, label %if.then, label %if.else if.then: ; preds = %entry store i32 3, i32* %i

Aha. Thanks. Seems like I need to call mapSectionAddress with the target address. But how I copy the code? What function would I call?

A need has arisen to generate code using MCJIT but not in the target process instead in a different process (and possibly even different machine though not in the scope). Reading through the tutorials and MCJIT design document, it seems like this is possible or was kept in mind during design of MCJIT. How do I achieve this? Are there examples?

In my language there are a lot of i16 definitions, but almost all of the time they are upgraded to i32 because my add operations only happen on i32. So to be representative to my language definition, I have a lots of Sext/Zext and Truncs pretty much every time I add or subtract. As soon as I pass through InstCombine things look much nicer, all the upcasts and downcasts go away, but my test cases
