Hi all, I understand from the document that I should be able to configure llvm with only specific targets by passing -DLLVM_TARGETS_TO_BUILD=some-backend to cmake. However, I get the following errors whenever I don't include X86 in the target list: CMake Error at cmake/modules/LLVMConfig.cmake:127 (message): Library `X86' not found in list of llvm libraries. Call Stack (most recent

Hi all, I'm trying to create a new backend for a processor, and I start with modifying the existing backends like MIPS and Microblaze. I have a problem when I try to add a register class in the Target's register description, it looks like this: def IGPRegs : RegisterClass<"MBlaze", [v8i16], 128, [PR0, PR1, PR2, PR3]>; // PR0 - PR3 are registers defined before I want to

Hi, I am wondering how to specify the selection DAG patterns for instructions that use accumulator. For example multiply-accumulate instruction with one destination operand and two source operands: mac $dst, $src1, $src2 ;; $dst += $src1*$src2 Seems that it has a cycle in the pattern. So how do I specify it in the DAG? There are a few instructions in the ARM backend like this one, but the

Hi all, I'm developing a backend for a custom architecture. The target architecture has different memory for different data types(vector and scalar). So is it possible to maintain two different stacks, one for vector and the other for scalar? ---- Regards, Dongrui She -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi all, I try to print the live-in and live-out registers for each basic block in a backend for my own target. And I can get a list of live-in registers directly in MachineBasicBlock. Is there a quick way to also get the list of live-out registers without redoing the analysis. I think this information is computed and stored somewhere. -- Regards, Dongrui -------------- next part

Hi, Have you try to directly describe such patterns in tblgen file? Like this: (brcond (i32 (cond_op RC:$rs, RC:$rt)), bb:$offset) MIPS backend does that. I also do this in my own backend, and seem to be working fine.

Hi All, I have a system running Linux x86_64. And I have the latest LLVM from the repo compiled and installed using CMake (2.8.10.2). In one of my projects, I need the LLVM libraries. So I use CMake to configure the compiler and linker flags ( Find_Package(LLVM Required) ). CMake is complaining about missing LLVM-Config when some users try to compile the project. I looked at the
