获取我的VC ++代码使用的符号列表 [英] Getting a List of Symbols Used by My VC++ Code

问题描述

我正在构建一个处理VC ++源代码的工具.为此，我需要获取符号列表，包括局部变量名称及其代码使用的类型.我知道Visual C ++ 2010已经提供了一个.bsc文件，该文件允许对象浏览器快速定位符号.但这是一个交互式工具.我需要获取文件中符号的列表.有什么工具可以让我们以编程方式获取我们自己的VC ++源代码中使用的符号列表?

I am building a tool that process my VC++ source codes. For this, I need to obtain a list of symbols including local variable names and their types used by my codes. I know Visual C++ 2010 already provides a .bsc file that allows the object browser to locate symbols quickly. But this is an interactive tool. I need to obtain a list of the symbols in a file. Is there any tools allowing us to programmatically obtain the list of symbols used in our own VC++ source codes?

我尝试了Microsoft提供的Debug Interface Access SDK.它允许我们读取.pdb文件以获取所用局部变量的名称.但是我也想获得我的源代码中使用的确切类型名称.例如

I tried the Debug Interface Access SDK provided by Microsoft. It allows us to read the .pdb file for the names of the local variables used. But I also want to obtain the exact type names used in my source codes. e.g.

MYTYPE dwordVar;

DIA SDK允许我们获取字符串"dwordVar"，它是局部变量的名称.但是它不能说出它的类型名是"MYTYPE".它只能告诉我们MYTYPE真正代表什么(如unsigned long).但是不是符号"MYTYPE".

DIA SDK allows us to obtain the string "dwordVar" which is the name of a local variable. But it cannot tell its type name is "MYTYPE". It can only tell us what MYTYPE really represents (like unsigned long). But not the symbol "MYTYPE".

如果Visual C ++不提供此功能，是否有任何第三方工具支持此功能?

If Visual C++ isnt offering this feature, is there any third party tools supporting this feature?

推荐答案

对此程序进行的实验:

typedef unsigned long MYTYPE;

int wmain(int argc, wchar_t *argv[])
{
    MYTYPE test = 99LU;
}

DIA SDK和DbgHelp都为test的类型符号的符号类型返回16(SymTagBaseType).如果类型符号是Typedef符号(17/SymTagTypedef)，那就太好了，但是可能是PDB本身不记录源文件在声明本地类型时是使用typedef还是类型名称.变量.

both DIA SDK and DbgHelp return 16 (SymTagBaseType) for the symtype of the type symbol for test. It would be nice if the type symbol were a Typedef symbol (17/SymTagTypedef), but it might be that the PDB itself does not record whether the source file used a typedef or type name in declaring the type of the local variable.

一种可能的解决方法是枚举全局作用域符号的SymTagTypedef子代，从类型的类型ID到typedef名称构建std::multimap.然后，对于每个局部变量，如果多图包含数据符号类型ID的条目(通过 IDiaSession::findLines 方法来找出声明了数据符号的行，并在这些行中搜索任何typedef名称字符串，可能在搜索之前执行预处理.

One possible work-around is to enumerate the SymTagTypedef children of the global scope symbol, building a std::multimap from type IDs of the types to the typedef names. Then, for each local variable, if the multimap contains entries for the Data symbol's type ID (obtained via IDiaSymbol::get_typeId), use the IDiaSession::findLines method to figure out the line(s) on which the Data symbol is declared and search those lines for any of the typedef name strings, possibly performing preprocessing before searching.
