Debug toy config
调试mlir的vscode环境配置¶
除了前文中在运行时指定调试打印参数，更加友好的方式可能就是gdb调试了。本节讲解一下vscode调试环境配置。 首先vscode打开llvm_project项目，采用debug模式编译项目:
cd build
cmake -G Ninja ../llvm -DLLVM_ENABLE_PROJECTS=mlir -DLLVM_BUILD_EXAMPLES=ON -DLLVM_TARGETS_TO_BUILD="X86" -DCMAKE_BUILD_TYPE=Debug -DLLVM_ENABLE_ASSERTIONS=ON -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DLLVM_ENABLE_LLD=ON
cmake --build . --target toyc-ch3
创建launch.json，添加以下内容：
{
"version": "0.2.0",
"configurations": [
{
"name": "OK_Gdb_Debugger",
"type": "cppdbg",
"request": "launch",
//要调试的程序
"program": "${workspaceFolder}/build/bin/toyc-ch3",
// "args": ["${workspaceFolder}/mlir/test/Examples/Toy/Ch2/codegen.toy","-emit=mlir", "-mlir-print-debuginfo"],
"args": [
"${workspaceFolder}/mlir/test/Examples/Toy/Ch3/transpose_transpose.toy", "-emit=mlir", "-opt"
],
"stopAtEntry": false,
"cwd": "${workspaceFolder}",
"environment": [],
"externalConsole": false,
"MIMode": "gdb",
"miDebuggerPath": "/usr/bin/gdb",
//gdb路径
// "miDebuggerPath": "/opt/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gdb",
// //远程调试，服务器地址，端口号。
// "miDebuggerServerAddress": "192.168.1.188:9091",
// "additionalSOLibSearchPath": "${workspaceFolder}/build/lib/"
// "setupCommands": [
// {
// "description": "Enable pretty-printing for gdb",
// "text": "-enable-pretty-printing",
// "ignoreFailures": true
// }
// ]
}
]
}
