String obfuscation NOT obfuscating in Windows

[pedroflor]

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

Results of the compiled source code with -mllvm -sobf 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?
