  target/riscv: configure and turn on vector extension from command line (2020-06-26 14:22:15 -0700)

----------------------------------------------------------------
This PR contains two patches to improve PLIC support in QEMU.

The rest of the PR is adding support for the v0.7.1 RISC-V vector
extensions. This is experimental support as the vector extensions are
still in a draft state.

Sure, I will.
I have applied for a gcc compile farm account today, but it maybe a few 
days later before I can login.
Please accept my apologies for my oversight.

Hi Peter,

Do you mean you built the patch set on PPC64 or s390x and got errors in 
the list? Or just a worry?

I have built the patch set on Ubuntu 18.04 X86-64. I don't know which 
compile option
will fails the compilation. If you compiled on Ubuntu x86-64, could you 
show me the
compile option?

As a note: I try to find a PPC64 for test, but I'm afraid it will be too 
later.
Is there an available  PPC64  machine in the community?

Thanks very much.

The related code in your patch "target/riscv: add vector stride load and 
store instructions" is in a "#ifdef HOST_WORDS_BIGENDIAN" section, so of 
course this bug does not trigger on a x86 host. You could temporarily 
turn the "#ifdef HOST_WORDS_BIGENDIAN" into a "#if 1" to see whether you 
can then also reproduce the error on x86.

Maybe the easiest way to test your code on a big endian machine, too, is 
to get a github account, clone the QEMU repository there, and enable 
Travis for that repo. Then your code gets built on some non-x86 
architectures (including a big-endian s390x) as soon as you push it to 
the repo (see .travis.yml for details).

You obviously must not use "&" with a pointer. I guess you have to cast 
to "uintptr_t" and back, or think of some other smart way to fix this.

Thanks very much. I will have a try.

Yes. That's the error. It  build successfully after the cast.

I'm sorry, but the new code fails to compile on big endian 32-bit
targets, see https://gitlab.com/huth/qemu/-/jobs/667762754#L3434 :

/builds/huth/qemu/target/riscv/vector_helper.c: In function 'vext_clear':
/builds/huth/qemu/target/riscv/vector_helper.c:154:16: error: cast to
pointer from integer of different size [-Werror=int-to-pointer-cast]
         memset((void *)((uintptr_t)tail & ~(7ULL)), 0, part1);
                ^
/builds/huth/qemu/target/riscv/vector_helper.c:155:16: error: cast to
pointer from integer of different size [-Werror=int-to-pointer-cast]
        memset((void *)(((uintptr_t)tail + 8) & ~(7ULL)), 0, part2);
                ^
cc1: all warnings being treated as errors

A quick work-around is maybe to replace "ULL" with simply "UL" ?

Or use QEMU_ALIGN_PTR_DOWN?

Sounds like a good idea! I'll give it a try and send a patch ...
