REM Script for building the LLVM installer on Windows,
REM used for the the weekly snapshots at http://www.llvm.org/builds.
REM
REM Usage: build_llvm_package.bat <revision>

REM Prerequisites:
REM
REM   Visual Studio 2019, CMake, Ninja, SVN, GNUWin32, SWIG, Python 3,
REM   NSIS with the strlen_8192 patch,
REM   Visual Studio 2019 SDK and Nuget (for the clang-format plugin),
REM   Perl (for the OpenMP run-time), 7Zip.

REM
REM   For LLDB, SWIG version <= 3.0.8 needs to be used to work around
REM   https://github.com/swig/swig/issues/769


REM You need to modify the paths below:

set revision=llvmorg-14.0.1
set package_version=14.0.1
set build_dir=llvm_package_1401-final

echo Revision: %revision%
echo Package version: %package_version%
echo Build dir: %build_dir%
echo.
