U-boot problem

jiangtao9999 · September 4, 2023, 7:35am

It seems riscv’s new version changed basic extensions set. It is split ziscr & zifencei from g-extension .
So , you need new compile tools to support new riscv version. I remember GCC >= 12 && Binutils >=2.40 is supported. But clang , maybe clang >= 15 ? I do not known.
Or , you can try let binutils’s tools run on old version. I think it is have parameters to set that.

PS: Why do you use clang with binutils’s gas, not with llvm-as?

But clang , maybe clang >= 15 ? I do not known.

Should be clang >= 17, but not available yet.

PS: Why do you use clang with binutils’s gas, not with llvm-as?

Because I don’t know better what options there are with all the gcc, clang, … stuff and I have not enough experience.

I removed gas and installed the OpenBSD llvm port, which contains it:

vf2# llvm-as --version
LLVM (http://llvm.org/):
  LLVM version 13.0.0
  Optimized build.
  Default target: riscv64-unknown-openbsd7.3
  Host CPU: (unknown)

vf2# gas --version                                                
ksh: gas: not found

How Do I “tell” gmake to actually “use” it? Is there some FLAG I can pass ?

jiangtao9999 · September 4, 2023, 9:03am

You need “tell” to Makefile, gmake is a interpreter.
In common AS=xxxx is enought. But it is dep on how the makefile writed.

And , I remember as is called by clang/gcc automatily. It is only add a paramter to tell clang use llvm’s as.

Or … Why you do not use gcc to compile it ?

Thanks a lot for comments. Tuned the makefile for AS=llvm-as but gave only additional errors.

Was thinking about the gcc approach before, but there were dependency errors and I could not install it. Managed to install “problematic” 2 dependencies with pkg_add as “standalone version”. Thereafter gcc installation was also possible.

It now looks “better”, but still the same error after a while:

Use “gmake V=1” to let it output compile-cmd.

I remember that gcc11 is not support zicsr & zifencei . Maybe your build tools is still wrong.

Yeah - I am compiling gcc-13.2.0 now. Let’s see if that works and thereafter I will report back again.
