Bug ID: 51072
Summary: Test passes on windows with a ninja build but not a
Visual Studio build
Product: Test Suite
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: lit
Assignee: unassignedb...@nondot.org
Reporter: orlando.hy...@sony.com
CC: dan...@zuster.org, llvm-bugs@lists.llvm.org
Git revision: main 0da3573a9ef9 (12th July 2021)
The test:
clang/test/utils/update_cc_test_checks/check-globals.test
This test passes on windows when run from a ninja build directory, but not from
a Visual Studio (2017) one. For the Visual Studio build I get this failure:
```
# command stderr:
lit.py: D:\dev\opensource-build-clang\tools\clang\test\lit.site.cfg.py:56:
fatal: unable to find 'build_mode' parameter, use '--param=build_mode=VALUE'
```
Repro steps:
1. Generate build
> cmake <path-to-llvm> -G "Visual Studio 15 2017" -A x64 -Thost=x64
> -DLLVM_PARALLEL_LINK_JOBS=1 -DLLVM_ENABLE_PROJECTS="clang"
> -DLLVM_ENABLE_ASSERTIONS=TRUE
2. Build
3. Run test
> python Release\bin\llvm-lit.py
> <path-to-llvm>/clang/test/utils/update_cc_test_checks/check-globals.test -v

# command stderr:

Failed Tests (1):
Clang :: utils/update_cc_test_checks/check-globals.test
If I build with ninja instead there is no issue:
1. Generate build
In a "x64 Native Tools Command Prompt for VS 2017" console:
> cmake <path-to-llvm> -G Ninja -DLLVM_PARALLEL_LINK_JOBS=1
> -DLLVM_ENABLE_PROJECTS="clang" -DLLVM_ENABLE_ASSERTIONS=TRUE
> -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_COMPILER=cl.exe
> -DCMAKE_C_COMPILER=cl.exe -DCMAKE_ASM_COMPILER=cl.exe -DCMAKE_LINKER=link.exe
2. Build
3. Run test
>python bin\llvm-lit.py
><patht-to-llvm>/clang/test/utils/update_cc_test_checks/check-globals.test -v
