similar to: llvm and simplescalar

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

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

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

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

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

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

We are trying to use LLVM (Clang as the C frontend) to generate code for 32-bit MIPS (little-endian)l, which can run on simplescalar 3.0 sslittle-na-sstrix platform. Can you advise what would be the right way to use the LLVM compiler infrastructure? The following is the one I used, but it appears that it produce the code in big-endian (and I wonder whether the calling convention is right.) To

It will produce little-endian code if you replace "mips" with "mipsel". 1. clang -ccc-host-triple mipsel-unknown-linux -ccc-clang-archs mipsel -O3 -S -emit-llvm foo.c -o foo.ll 2. llc -march=mipsel -mcpu=4ke foo.ll -o foo.s (the -march option is redundant) If you do not specify the target cpu with -mcpu, by default it will generate code for Mips1, which has not been tested as

Hi, We have tried and generate assembly code for very simple test C code. But, binutils-2.5.2 (simplesim-3.0) cannot handle the produced assembly code with the following complaints. Could you advise which version of bitutils that we need to use for mips code with LLVM with Clang? Thanks, $ GCC addr01.s addr01.s: Assembler messages: addr01.s:1: Error: Unknown pseudo-op: `.section'

Hello, One of my users has a mailbox named 'INBOX.Kron & SPM' (maybe created a long time ago, when we use courier imap as pop/imap server, but I'm not sure). I can see the maildir with a doveadm list command: amateo_adm at myotis31:~$ sudo doveadm mailbox list -u <user> ... INBOX.Kron & SPM ... but I can't delete it, neithe rename it: amateo_adm at

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 posted this question yesterday and for some reason the post seems to be attached to the wrong thread. Also, I extended my test a little and it seems to indicate the problem is with spm. I would appreciate any help. Thanks. ========================================================== library(plyr) library(SemiPar) data <-
