This PR fixes the codegen llvm version requirement. Prior to this PR, we use `dbg_info_->di_builder_->insertDeclare` when LLVM version is at least 19.0, while the new `insertDeclare` interface starts with LLVM 20: * 19.1.0: https://github.com/llvm/llvm-project/blob/llvmorg-19.1.0/llvm/include/llvm/IR/DIBuilder.h#L95-L98 * 20.1.0: https://github.com/llvm/llvm-project/blob/llvmorg-20.1.0/llvm/include/llvm/IR/DIBuilder.h#L950-L952 As a result, we may run into the following compilation error if the LLVM version happens to be 19: ``` /home/ruihangl/Workspace/tvm/src/target/llvm/codegen_llvm.cc:2251:42: error: no matching function for call to 'llvm::DIBuilder::insertDeclare(llvm::AllocaInst*&, llvm::DILocalVariable*&, llvm::DIExpression*, llvm::DebugLoc, llvm::BasicBlock::iterator)' 2251 | dbg_info_->di_builder_->insertDeclare( | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^ 2252 | paramAlloca, param, dbg_info_->di_builder_->createExpression(), llvm::DebugLoc(di_loc), | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 2253 | llvm::BasicBlock::iterator(store)); | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /home/ruihangl/Workspace/tvm/src/target/llvm/codegen_llvm.cc:2293:42: error: no matching function for call to 'llvm::DIBuilder::insertDeclare(llvm::Value*&, llvm::DILocalVariable*&, llvm::DIExpression*, llvm::DebugLoc, llvm::BasicBlock::iterator)' 2293 | dbg_info_->di_builder_->insertDeclare( | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^ 2294 | llvm_value, local_var, dbg_info_->di_builder_->createExpression(), llvm::DebugLoc(di_loc), | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 2295 | llvm::BasicBlock::iterator(insert_before)); | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ``` To fixed this, we update the version requirement to LLVM 20. -- This is an automated message from the Apache Git Service.
