...m). Editor has outline, folding, coloring, go to definition, etc. As any prototype, editor has some limitations (e.g. no cross-file indexing). If there is any interest to such tool I will improve it a bit and then publish. Also considering llvm asm (ll) editing and build support.

...se started a plugin to cause Eclipse to compile with LLVM-GCC but I hadn't heard anything else from them. I've been just modifying the commands manually for that.

Hi, I'm working on LLVM based compiler. Editing td, llvm asm files a lot. Is there any plug-in (coloring, open declaration, etc) for Eclipse IDE for these files? If not, is there any interest to such plug-in? Regards, Sergey Y.

Hi, Target architecture for llc can be specified using -march, -mcpu, -mattr options. Is it possible to override target CPU attributes when using llvm-gcc compiler? Regards, Sergey Y.

I tried llc with -mcpu=help and it dosn't list Sparc.

I'm building tool-chain for processor without integer MUL. So, I've defined __mulsi3 for integer multiplication (int32). Now I've got a problem with int64 multiplication which is implemented in libgcc2.c. Segfualt due to infinite recursion in i64 soft multiplication (libgcc2, __muldi3). LLVM-GCC (for my target) misoptimizes code if -O2 is passed. It promotes i32 multiplication to

Is it possible to configure llc to generate code for other architectures? For instance, what I need to do to generate Sparc machine code?

Hi David, I'm working on source to source transformations and instrumentation. A flag to disable 'va_arg' lowering in LLVM FEs will be very useful. Have you sent your modifications upstream to LLVM? If not, could you please share link to your public repository.

Hi, Rafael Inlined asm markup inside functions and on the top level is used to split asm prologue/epilogue parts in very fine-grained manner. So, splitting source c won't give the same result.

Thanks, yes, I'm facing the same issue. Hm... seems there are no simple fixes. I have to do one more i64 mul implementation to workaround aggressive optimizations. Is that correct? Is this the only way? Can I disable only one particular pass which does this promotion from i32 to i64 using some LLVM-GCC option? Are there other libgcc functions affected by this optimization? Regards, Sergey
