String obfuscation NOT obfuscating in Windows
Patch & build in Linux, String obfuscation works properly.
Patch & build in Windows, String obfuscation simple doesn't works.

Build process:
cmake -S llvm -B build -G Ninja -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_PROJECTS="clang;libcxx;libcxxabi" -DLLVM_ENABLE_ASSERTIONS=No -DLLVM_ENABLE_NEW_PASS_MANAGER=Off

Compiling with string obfuscation option -mmlvm -sobf
C:\>\llvm-project_14.x\build\bin\clang.exe -mllvm -sobf hello.c -o hello.exe

Source code to test
image

Results of the compiled source code with -mllvm -sobf
image
As seen in the image, the strings remains intact (not obfuscated).

Software:

  • OS: Windows 10
  • Visual Studio 2022
  • LLVM 14.0.6
  • cflag: -mllvm -sobf

Did you ever get this working? Also could the error be caused by you disabling the newpass?
