similar to: [LLVMdev] Problems compiling for new back-end

Hello Per, > ...and the output has the x86_64 triple and datalayout anyway. How are you > supposed to develop new back-ends if neither compiler can cross-compile? > Target is a DSP, so native compile is entirely impossible. clang support for cross-compilation definitely requires alot of care. It the meantime you can forward a target triplet to clang via -ccc-host-triple hidden command

This worked quite well! Seems to me it definitely shouldn't be a hidden option. Compiling with the new (correct) triple, llvm has started taking the register arguments and putting them on the stack. Is there an easy way to stop this, or do I have to match/rebuild the dag somehow? //Per On Fri, Nov 26, 2010 at 10:14 AM, Anton Korobeynikov < anton at korobeynikov.info> wrote: >

Hi all. I would like to declare a function that takes a function pointer as an argument. In C, it would be : void execute(char (*func)(void*), void *param) So, in my compiler, I have : std::vector<const Type *> cbFPtrArgs(1, Type::getInt8PtrTy(C)); FunctionType * cbFPtrTy = FunctionType::get(Type::getInt8Ty(C), cbFPtrArgs, false); Function * func =

You need a pointer-to-function type, but FunctionType just gives you a function type. Use PointerType::getUnqual(FunctionType::get(...)). Or TypeBuilder<char (*func)(void*), false>::get(context) from Support/TypeBuilder.h.

I am working on implementing a new target for llvm. So far (to make debugging easier), I was compiling a C code into 2 steps: 1) generate the llvm file: clang -ccc-host-triple mytarget -emit-llvm -S myfile.c -o myfile.ll 2) generate the assembly file using llc -march=mytarget myfile.ll Sometimes, I add some verbosity for the 2nd command like "-print-after-all". Now, I'd like to

Hi, I am passing a data frame and field name to a function. I've figured out how I can create the formula based on the passed in field name, but I'm struggling to create a vector based in that field. for example if I hard code with the actual field name Y = df$Target, everything works fine. but if I use the passed in parameter name, it doesn't give me what I want, Y = df$mytarget

Hi! I started writing a LLVM backend for a custom architecture. I have some register and instruction .td files and some other files/classes like a MCStreamer for assembler output. At the moment I can compile some empty programs so far. I implemented the method ::eliminateFrameIndex() similar to the Sparc and ARM backend. The method looks like this: // frame pointer is in reg of class

So getting the latest release_28 branch should be equivalent, yes? I just want to make sure we have a way to test 2.8 long-term. -Dave

Hi, Is there a way to see what the default argument llc takes from clang/clang++ ? I'm debugging my backend with a very simple c++ program. Running through *clang++ -target myTarget -S simple.cpp -o simple.s * (bug does no show up) gives me different results from *clang++ -target myTarget -S -emit-llvm -o simple.cpp -o simple.ll* *llc simple.ll -o simple.s *(bug shows up) Just trying to

Hello, Given a TargetRegisterClass *RC, I was wondering if there is a way to find out what register class it is directly, instead of comparing it against all the &mytarget::Class1, &mytarget::Class2 etc. This goes back to my original intention of having special query functions for a subset of register classes. Suppose I wanted vector register classes (more than one, say 2-elements and

I'm trying to create a simplified 2 slot VLIW from an OR1K. The codebase I'm working with is here <https://github.com/openrisc/llvm-or1k>. I've created an initial MyTargetSchedule.td def MyTargetModel : SchedMachineModel { // HW can decode 2 instructions per cycle. let IssueWidth = 2; let LoadLatency = 4; let MispredictPenalty = 16; // This flag is set to allow the

It just occured to me that perhaps what happens is that since the cmp-instruction is initially followed by the pseudo-instruction - which doesn't have Uses = [CFR] - that it's marked dead initially, and never changed back when the SKIPCOND is inserted by the custom emitter? But I feel that this would happen in e.g. MSP430 too then... On Wed, Dec 15, 2010 at 10:14 AM, Anton Korobeynikov

I try to define a register class def GPR64 : RegisterClass<"mytarget", [i64], 64, [T0, T1.....] to simulate even/odd pair of GPR32 register. Actually, I just use GPR64 as a temporary register. My CPU just support i32 Integer type directly. I use FDR to save f64. def FDR : RegisterClass<"mytarget", [f64], 64,[FD0, FD1, ....] When I move f64 to even/odd pair register, I
