similar to: [LLVMdev] llvm cross compilation and simplescalar simulation for ARM

Simplescalar is not compatible with llvm because the binutils simplescalar is based on is ancient.

It use to. alphasim (the validated alpha model based on simplescalar) is better though. Also, since no one has needed to run simplescalar experiments, the alpha backend has bitrotted some. The last version that I know worked with most of spec was llvm 1.8 or so. You need to get or write an elf64 loader and fix a couple instruction implementations in simplescalar to get it to run linux binaries

We are using simplescalar 3.0 as an architecture simulation platform for our research. The current version of the simplescalar still uses gnu binutils 1.5. and gcc-2.7.2 to generate 32bit mips code. We are currently trying to replace gcc-2.7.2 by LLVM current. However, the generated code cannot be processed by this old binutils-1.5. We expect that it can be quite difficult to make simplescalar use

Hello, I want to compile MiBench by clang, and the target-ISA is armv4. The code generated using llvm-2.9, clang-2.9, and arm-linux-gcc (gcc version 2.95.2), simulator is sim-panalyzer 2.0.3 . I use these commends: $ clang -O3 -o hello.ll -c -emit-llvm hello.c $ llc -O3 -o hello.s -march=arm -mcpu=strongarm1100 hello.ll $ arm-linux-gcc -O3 -march=armv4 -mcpu=strongarm1100 -static

Thank you for your answers and suggestions! Well, I want to do some experiments about the compiler optimization in llvm under SPM and I need performance evaluation. As I know, alpha is a general-purpose CPU, so I consider that arm may be an alternative. Simplesim-arm is able to do performance simulation while m5-arm is still under development. Then, what should I do? Do the experiment under

Dear all I use arm-linux-gcc 2.95.2, because the code generated by version 3.X and 4.X can not run on SimpleScalar. So I use the arm-linux-gcc 2.95.2 *only*, the version is recommended by SimpleScalar. The code generated by arm-linux-gcc 2.95.2 can run on SimpleScalar. Now I want to use llvm/clang to generate ARM assembly code and arm-linux-gcc 2.95.2 to be assembler. Unfortunately, I got some

hello everyone, I'm wondering whether llvm can work together with simplescalar. Would anyone please give me some clarification? Thanks a lot!

I tried llvm/clang-3.1 previously. It was not work, so I use version 2.9 now.

These errors are from the assembler, not LLVM. Specifically, your binutils is too old. Given that it doesn't even recognize the ".syntax" directive, they're *very* much too old. You need to upgrade. -Jim On Sep 24, 2012, at 3:31 AM, 陳奕梅 <ymchen at sslab5.cs.nctu.edu.tw> wrote: > Hello, > > I want to compile MiBench by clang, and the target-ISA is armv4. The

> I am using SimpleScalar cross-compiler 2.95.2 (http://www.simplescalar.com/v4test.html) It's really ancient. Consider upgrading to something not from stone age :) I doubt you'll be able to assemble anything generated by, for example, with mainline gcc. -- With best regards, Anton Korobeynikov Faculty of Mathematics and Mechanics, Saint Petersburg State University

wow... Tell me, what cross compiler can I use for ARM if I am working in a i686-Linux machine? At the same time, how I can simulate it? But the way, If I deleted the unknown pseudo-op and change section .rodata definition, I can use my stone age cross compiler. I am just wondering why it works without them. Thanks in advance.

Hi Susan, Jakob pointed out to me that the Gcra.cpp allocator doesn't record basic-block live-ins, which are used by the verifier to check correctness. You can record which variables are live into a basic block with MachineBasicBlock::addLiveIn(unsigned physReg). I don't know the verifier well, but if it's using other built in infrastructure for register allocation then it may not be

Hi sri, As your problem involves a few logical steps, I found it easier to approach it in a stepwise way. Perhaps there are more elegant ways to accomplish this. svdat<-read.table(text="Count id name type 117 335 sally A 19 335 sally A 167 335 sally B 18 340 susan A 56 340 susan A 22 340 susan B 53 340 susan B 135 351 lee A 114 351 lee A 84 351 lee A 80 351 lee A 19 351 lee A 8 351 lee A
