Reorder and merge patches to make things keep building for each separate patch.

- Patches 1-4 add some new IROps, a new IRMBusEvent and a new IRJumpKind to libVEX.
- Patches 5-6 add the VEX and decode infrastructure for LOONGARCH64.
- Patch 7 enables the LOONGARCH64/Linux target in the build system.

Since then, Valgrind for LOONGARCH64/Linux can be compiled on LoongArch64 Linux, or cross-compiled on other machines.

- Patches 8-21 add support for the libVEX loongarch64 front end.
- Patches 22-76 add support for the libVEX loongarch64 back end.

Since then, libVEX for loongarch64 can translate loongarch64 to loongarch64 properly.

- Patch 77 updates vbit test for loongarch64.
- Patch 78-99 add LOONGARCH64/Linux support for core and tools.
- Patch 100 makes libVEX always use fallback LLSC on loongarch64.

Since then, Vaglrind can run on LOONGARCH64/Linux properly.

-Patch 101-121 implement and add tests for LOONGARCH64/Linux.

Since then, Vaglrind can pass a large number of regression tests on LOONGARCH64/Linux.

- Patch 122 sets up nightly testing for loongarch64.
- Patch 123 adds a simple README for loongarch64.

Rebased on 3.20.0.

With a build based on 45c61d598f435d59302dea084912cd3390de1ffc

There was 1 merge rejection:
./helgrind/tests/Makefile.am.rej
due to an extra filter I added

I get a few warnings

I don't think that the changes and extra test for helgrind tls_threads are still necessary.

I get one regtest failure.

none/tests/libvexmultiarch_test 1 0 0

Gives me
vex: priv/host_loongarch64_isel.c:2659 (void iselNext(ISelEnv *, IRExpr *, IRJumpKind, Int)): Assertion `0' failed.
//// failure exit called by libVEX

I had a quick lock at the modified code, looks OK to me.

I haven't looked at the added files yet.

Thank you for your review!

I will remove the changes and extra test for helgrind tls_threads.

I ran make regtest on both amd64-linux and loongarch64-linux, but neither of them reported the makefile consistency error. So I don't know how these errors are generated. Could you help me?

I will remove them.

It seems that I need to add Ijk_Call and Ijk_Ret support for loongarch64.

Sorry, my fault, I didn't look carefully, a lot of them were warnings about the artifacts left over after merging the patches.

If I run  gmake post-regtest-checks then I get

helgrind/tests/Makefile.am:1: error: tls_threads_tunable.stdout.exp is in EXTRA_DIST but doesn't exist
none/tests/loongarch64/Makefile.am:1: error: atomic.stderr.exp is in EXTRA_DIST but doesn't exist

none/tests/loongarch64/Makefile.am:1: error: special.stderr.exp is in EXTRA_DIST but doesn't exist

The first one might be because I badly resolved merge issues.

I don't see any stderr.exp referred to in none/tests/loongarch64/Makefile.am

They are empty files and I can find them in my local tree.
I might have forgotten to add them.

Created attachment 155754 [details]
patches-v4

Rebased on a1f365150565e3dd69666ebac85bf535bbe194a1.

Fix build warnings.
Add Ijk_Call and Ijk_Ret support for LoongArch64, which fixes none/tests/libvexmultiarch_test.
Remove changes and extra test for helgrind tls_threads.

Now we can use QEMU 7.2 for testing:
https://github.com/loongson/valgrind-loongarch64/releases/tag/v3.21-GIT

Testing on FreeBSD (13.1 amd64 with the system clang).

First off, no warnings. Just one for "make". There are a few from "make check" but I only just noticed them and I think they come from my own attempt to silence GCC (bug clang doesn't recognize them).

I still et quite a few EXTRA_DIST warnings:

EXTRA_DIST is for hidden dependencies that need to be included in the tarball for targets like dist-bzip2

Same mistake as last time, didn't delete the merge artifacts.

Most of these files were introduced by the v4-0104 patch.
I don't know why these empty files are missing :)
Or can I just remove them from my local tree and EXTRA_DIST?

Many of the testcases have a 0 sized expected, 500 or so of them. regtest still needs them to check that the output is also empty (no false positives).

I was using 'patch' for my testing. Maybe that's the problem. I'll try again with 'git apply'.

If the tests expect no output, then an empty .exp file is needed.
You can just git add them to the commit (it looks like you did for most, but not all new .exp files).
And they should all be listed under EXTRA_DIST.

It was my fault.

for p in v4*.patch ; do git apply --allow-empty $p ; done
