Hi, I'm trying to emit FP_ROUND f64 -> f32 considering a mips target that only supports single float point operations. The problem is that f32 is considered legal on this target but f64 doesn't and the only way I can codegen this instruction is using setConvertAction(MVT::f64, MVT::f32, Expand), which issues a EmitStackConvert. What if I want a libcall instead? What should I do? The

Hi, well, I downloaded the head revision of llvm and llvm-gcc. As you said it hangs at: Formal argument #0 has unhandled type f32 /home/julio/trunk/llvm-gcc/gcc/libgcc2.c:1765: internal compiler error: Abortado Please submit a full bug report, with preprocessed source if appropriate. Actually, I don't need fp, there is any way to disable? By the way, I'm working with a MIPS coprocessor

Hi, The code that I was using was this: http://shootout.alioth.debian.org/u32q/benchmark.php?test=nbody&lang=gcc&id=1 I followed the footsteps for compiling it to BC than I took the BC code and compiled it with ilasm2 (Mono). After that I tried to run the .exe with mono and it gave me a invalid opcode. I wish I could give more information about the bug but my ext3fs partition crashed

And one last thing, the problem seems to be related to libcpp. Using only C frontend will work? 2008/7/7 Julio <julio.martin.hidalgo at gmail.com>: > Hi, well, I downloaded the head revision of llvm and llvm-gcc.

Hello everyone, I'm a little new to LLVM. I know that the backends are still in experimental stage. MSIL and MIPS would be very useful for a project that I'm working on. Do you have any plans to have it completed in the next few months? I could generate the MSIL assembly but when compiled it, which compiles sucessfully, it generates invalid opcode errors.

Hello, I'm trying to compile llvm-gcc to crosscompile mips. I have already modified a config.gcc to add mips as a target with llvm, but it gives me "Did not get a target machine!" (from llvm-backend.cpp). I thought that I had to modify TargetMachOWriterInfo.h with MIPS info, but now the problem is that I don't know where can I get the <mach/machine.h> (I don't have it

OK, so the next thing I found in Sparc world is that sparc-elf-as doesn't understand .bss as a directive for some reason. I modified the Sparc code generator to output .section ".bss" and that works just fine. My (temporary) solution is a hack, however: ================================================================== --- SparcAsmPrinter.cpp (revision 720) +++

I have installed LLVM on my machine (ubuntu) a while ago. I think my LLVM version is 2.8. is it supported in 2.8 ? When I install i didn't configure LLVM for mips. Do I have to configure it when I build ? Thanks in advance. Really appreciate it. --- On Thu, 9/1/11, Bruno Cardoso Lopes <bruno.cardoso at gmail.com> wrote: From: Bruno Cardoso Lopes <bruno.cardoso at gmail.com>

Hello, I'm interested on implementing the MIPS backend as a student in a compiler course on my university, starting in 2 weeks from now!! I've seen on the mailing list history no one has done it so far (although a lot said they would)! am i right?

Hi Renato, > This book also sucked a lot from the public documents, which is a shame. We cited the official docs a lot in the book, explicitly saying they are the definitive place to look for updated guidance. Since it's a book for beginners there's likely a lot of intersection with official docs content, but I don't remember I or Rafael sucking directly from them :-) Let us know

Do I have to configure it when I build ? I don't know what's the default llvm configuration for ubuntu! But you can check for mips support using "llc --version". Yes, it's supported in 2.8, although it
