FYI @liushuyu. Looking pretty good, just some sanitizer problems with the distro sanitizer libs, the buggy codegen/xtensa.d that you've fixed in the LLVM 19 PR (IIRC), and otherwise just a single gdb-related failure with gdb v15.0, for a missed global again (imported from another module, referenced by identifier only):

ldc/tests/debuginfo/print_gdb.d

Line 100 in 40716be

// GDB: p b_Glob

just some sanitizer problems with the distro sanitizer libs

This is due to Docker blocking the ASLR disable request (because it's a security risk). See moby/moby#43011. The temporary workaround is to disable the container security features (or enable privileged).

otherwise just a single gdb-related failure with gdb v15.0, for a missed global again (imported from another module, referenced by identifier only):

(gdb) p inputs.import_b.b_Glob
$2 = 99.8799973

This works. I don't know if this should be the correct behaviour, though.

Work around possible remaining gdb v15 regression in tests/debuginfo/print_gdb.d

I think I will still open a bug report for GDB, as LLDB (which does not have D support) can resolve this symbol without the namespace:

* thread #1, name = 'print_gdb', stop reason = breakpoint 1.1
    frame #0: 0x00005555555552f2 print_gdb`D main at print_gdb.d:103:5
   100  // GDB: p b_Glob
   101  // CHECK: = 99.8
   102
-> 103      cC clsC = new cC;
   104      clsC.classMemberFunc(2);
   105      cC.classStaticFunc(4);
   106      clsC.mixedVal++;
(lldb) p b_Glob
error: print_gdb [0x000000000000002f]: unhandled type tag DW_TAG_module (DW_TAG_module), please file a bug and attach the file at the start of this error message
(float) 99.8799972
(lldb)

(Although it might look like LLDB did not correctly handle module declaration)

Congratulations on making the scripts run on someone else's computer (aka CI)!

I think you can just cherry-pick 8387651 to make the remainder of the CI tests pass.
