.... For the shader instruction also found in LLVM IR, the conversion is trivial: <code> llvm::Value * Instructions::mul(llvm::Value *in1, llvm::Value *in2) { return m_builder.CreateMul(in1, in2, name("mul")); // m_builder is a llvm::IRBuilder } </code> However, the special instrucions cannot directly be mapped to LLVM IR, like "min", the conversion involves in 'extract' the vector, create less-than-compare, create 'select' instruction, and create 'insert-element' instruction. <code> llvm::Value * Instructions::min(llvm::Value *in1, llvm:...

Hi, I am trying to build a package from source for the first time. I'm using Windows XP. After R CMD INSTALL or R CMD check I get an error message that I don't understand. I've tried to follow the instrucions provided in the R Installation and Administration .pdf and the text file that comes with Rtools, but most of this is new to me and clearly I'm missing something. Here's what I've done: -Downloaded perl and Rtools and put them in my c directory -Used package.skeleton() to set up the pa...

Hi all, I'm very instresting in LLVM, and trying to port a dsp target on LLVM now. I found that, the Greddy Register Allocator will generate a reload instrucion just between the function call and ADJCALLSTACKUP instruction. If the reload instruction is transfered to be a load instruction finally, which uses the SP register as an operand, and the target uses the ADJCALLSTACKUP instruction to adjust the SP register's value, will the reload instruction ge...

...etelementptr` is already expanded into some arithmetic expression of a base address and some arbitrary offset calculations. So for example, with this code: %switch.gep = getelementptr inbounds [15 x i8], [15 x i8]* @switch.table, i16 0, i16 %2 %switch.load = load i8, i8* %switch.gep, align 1 by instrucion selection time, the argument to 'load' is (add (sign_extend (CopyFromReg %vreg2)) (WRAPPER TargetGlobalAddress<@switch.table>)) not a WRAPPER directly.

Hi Adam, John is right, the TCE stuff would be useful for you. Our compiler targets a processor template that the designer can populate pretty freely. The compiler then reads the architecture description and creates an LLVM backend on the fly. Please don't hesitate to get in touch with us if you have questions. -- Pertti

Hi, I've been looking at the new AVR backend lately, and one issue I've found is that all 'load' IR instructions are matched using the 'ld' AVR instruction, including 'load's for lookup tables generated from switches. On the AVR architecture, RAM and the program image are in completely separated namespaces. There's a distinct 'lpm' (Load from Program

Hello gyus, I am working on a project, where we are trying to create a development environment for new ASIP processor design. Part of this project is a compiler generator, where we would like to generate C compiler from some instruction description. To keep it short, let's say, that in each instruction's semantics is described by some C code. What I would like to do is to compile this
