Okay, I ran a test again with revision from 25th November 2025 
(2f8e71287542a597be246d34699c93345d096f22).

The file that runs into high memory consumption is this one:

```console
bash-5.3# ls -lha 
/builddir/build/BUILD/llvm-22.0.0_pre20251125.g2f8e71287542a5-build/llvm-project-2f8e71287542a597be246d34699c93345d096f22/llvm/redhat-linux-build/./bin/../lib/clang/22/lib/libclc/gfx1251-amdgcn--.bc
lrwxrwxrwx. 1 mockbuild mock 18 Nov 25 10:52 
/builddir/build/BUILD/llvm-22.0.0_pre20251125.g2f8e71287542a5-build/llvm-project-2f8e71287542a597be246d34699c93345d096f22/llvm/redhat-linux-build/./bin/../lib/clang/22/lib/libclc/gfx1251-amdgcn--.bc
 -> tahiti-amdgcn--.bc
```

The actual link target is this:

```console
bash-5.3# ls -lha 
/builddir/build/BUILD/llvm-22.0.0_pre20251125.g2f8e71287542a5-build/llvm-project-2f8e71287542a597be246d34699c93345d096f22/llvm/redhat-linux-build/./bin/../lib/clang/22/lib/libclc/tahiti-amdgcn--.bc

```

At the beginning of the compilation:

During high memory consumption:
