[LIBCXX] Record 'INPUT' does not have a filed named 'HelpTextsForVarivants'

[GaoXiangYa]

When I build the llvm-project libcxx libcxxabi on release/18.x branch, use this command:

git checkout release/18.x
mkdir build && cd build
cmake ../llvm \
-DCMAKE_INSTALL_PREFIX=/home/llvm-loongarch \
-DCMAKE_C_COMPILER=loongarch64-linux-gnu-gcc\
 -DCMAKE_CXX_COMPILER=loongarch64-linux-gnu-g++ \
-DCMAKE_ASM_COMPILER=loongarch64-linux-gnu-gcc \
-DCMAKE_CROSSCOMPILING=ON \
-DCMAKE_SYSROOT=/home/gf_loongarch_tools/loongson-gnu-toolchain-8.3-x86_64-loongarch64-linux-gnu-rc1.6/loongarch64-linux-gnu/sysroot/\
-DCMAKE_CXX_FLAGS="-target loongarch64-unknown-linux-gnu --sysroot=/home/gf_loongarch_tools/loongson-gnu-toolchain-8.3-x86_64-loongarch64-linux-gnu-rc1.6/loongarch64-linux-gnu/sysroot/ "\
 -DLLVM_ENABLE_RUNTIMES="libcxx;libcxxabi;libc" \
-DCMAKE_INSTALL_DEFAULT_COMPONENTS="cxx;cxxabi"\
 -DLIBCXX_ENABLE_SHARED=OFF \
-DLIBCXX_ENABLE_STATIC=ON \
-DLIBCXXABI_ENABLE_SHARED=OFF \
-DLIBCXXABI_ENABLE_STATIC=ON  \
-DCMAKE_CXX_FLAGS="-fPIC" \
-DCMAKE_C_FLAGS="-fPIC" \
-DCMAKE_BUILD_TYPE=Release \
-DLLVM_INCLUDE_TESTS=OFF \
-DCMAKE_C_COMPILER_TARGET=loongarch64-unknown-linux-gnu \
-DCMAKE_CXX_COMPILER_TARGET=loongarch64-unknown-linux-gnu \
-DLLVM_TABLEGEN=/home/llvm-tools/llvm-tblgen
make cxx cxxabi -j20

I meet this problem:

llvm/Option/OptParser.td:262:5: error: Record 'INPUT' doest not have a filed named 'HelpTextsForVariants'!

Could you please try 21 Release Candidate or main branch? Only most recent release is maintained.

Thanks， I solved this problem, my llvm-tblgen version does not match the llvm code, I use branch release/18.x to build the llvm-tblgen, and build release/18.x libcxx.
