Because I got error when I use arm-linux-gcc (gcc version 3.X or 4.X), I use officially recommended version 2.95,2. I don't know what's her problem while using newer toolchain. :/ 奕梅,you should use latest toolchain if possible, and post your problem here to see if it comes from LLVM/Clang or other place. Also, where do you read that version is recommended? Regards, chenwj -- Wei-Ren Chen (陳韋任) Computer Systems Lab, Institute of Information Science, Academia Sinica, Taiwan (R.O.C.)

[LLVMdev] [Questions] clang cross compilation and SimpleScalar simulation
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 below : hello.s: Assembler messages: hello.s:1: Error: Unknown pseudo-op: `.syntax' hello.s:2: Error: Unknown pseudo-op: `.eabi_attribute' hello.s:3: Error: Unknown pseudo-op: `.eabi_attribute' hello.s:4: Error: Unknown pseudo-op: `.eabi_attribute' hello.s:5: Error: Unknown pseudo-op: `.eabi_attribute' hello.s:6: Error: Unknown pseudo-op: `.eabi_attribute' make: *** [all] Error 1 Then I try commends : $ clang -ccc-host-triple armv4-none-linux-gnueabi -c hello.c -emit-llvm -o hello.bc $ llc -O3 -o hello.s -march=arm -mcpu=strongarm1100 hello.bc $ arm-linux-gcc -mcpu=strongarm1100 hello.s -static -O3 -o hello I got some error messages: hello.s: Assembler messages: hello.s:1: Error: Unknown pseudo-op: `.syntax' hello.s:2: Error: Unknown pseudo-op: `.eabi_attribute' hello.s:3: Error: Unknown pseudo-op: `.eabi_attribute' hello.s:4: Error: Unknown pseudo-op: `.eabi_attribute' hello.s:5: Error: Unknown pseudo-op: `.eabi_attribute' hello.s:6: Error: Unknown pseudo-op: `.eabi_attribute' hello.s:14: Error: bad instruction `push {r11,lr}' hello.s:18: Error: bad instruction `pop {r11,lr}' hello.s:28: Warning: Unrecognized .section attribute: want a,w,x hello.s:28: Warning: Unrecognized .section attribute: want a,w,x hello.s:28: Error: Rest of line ignored.

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

> The version recommended by SimpleScalar : > gcc 2.95.2 > binutils 2.10 > glibc 2.1.3These versions are ancient: at least 12 years old. Surely they do no support the unified ARM assembler syntax. So, you're out of luck here - you need to use much newer versions of tools. -- With best regards, Anton Korobeynikov Faculty of Mathematics and Mechanics, Saint Petersburg State University
