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

Hi, I want to explorer affection of compiler on low power. For the project background, I tend to process this work via LLVM, rather than GCC. And the Target is ARM. For this purpose, clang(3.2) + arm-gcc + simplescalar-arm(and panalyzer) seems to be a good choice. But I encounter several problems in the processing of setup the environment. ---------------------------------- 1. Firstly, arm toolchain is built via ‘buildroot-2012.08’: arm-linux-gcc, I compile MiBench step by step or on one step as follows: clang...

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...

Simplescalar is not compatible with llvm because the binutils simplescalar is based on is ancient. Jim On Sep 26, 2012, at 12:21 AM, 陳奕梅 <ymchen at sslab.cs.nctu.edu.tw> wrote: > 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 SimpleSc...

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 binu...

...uld I do? Do the experiment under m5-alpha or use simplesim-arm? And if I choose to use m5-alpha, can I use llvm as the compiler for this simulator? 2008-06-17 左琦 发件人： David Greene 发送时间： 2008-06-17 00:36:59 收件人： llvmdev at cs.uiuc.edu 抄送： 左琦 主题： Re: [LLVMdev] [llvm-announce] llvm and simplescalar On Sunday 15 June 2008 22:30, Andrew Lenharth wrote: > It use to. alphasim (the validated alpha model based on simplescalar) > is better though.

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 error messages be...

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

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

..., 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.

Hello, I'm trying to evaluate the performance improvement of instruction scheduling on one of the inorder ARM processor, I was looking for ARM simulator and I found two (Simplescalar/ARM and SimIt-ARM) The code generated using llvm-2.9 and llvm-gcc and gcc 3.2. I used these command : $ llvm-gcc -O3 -o test1.bc -c --emit-llvm test1.c $ llc -O3 -o test1.s -march=arm test1.bc -mcpu=strongarm110 $ arm-linux-gcc test1.s -mcpu=strongarm110 -static -O3 -o test1 $ ./sim-uop test1 U...

I don't think I ever said that the MIPS target is broken. I am simply trying to branch out one additional llc target for SimpleScalar PISA architecture.
