Hello,
I want to retrieve maximal debug information which is generated after clang execution
I checked the functionality for clang : DIBuilder,CGDebugInfo,DwarfDebug classes in the clang.
They generate wide spectrum of data (For example I saw for Class type - base classes /inheritance/friends etc.)
i want to see all the data for debugging after clang is executed…To check this I made following example
class friendClass
{
public:
int x;
};
class classBase
{
public:
int get1(){return 1;}
int get2(){return 2;}
};
class classDer:public classBase
{
public:
int get1(){return 1;}
friend class frienClass;
};int f()
{
classDer x;
return x.get1();
}
After C:\Windows\system32>clang C:\clangParam\clangExample.cpp -S -emit-llvm -o -
I get following output
; ModuleID = ‘C:\clangParam\clangExample.cpp’
target datalayout = “e-p:32:32:32-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:64:64-f32:32:32-f64:64:64-f80:128:128-v64:64:64-v128:128:128-a0:0:64-f80:32:32-n8:16:32”
target triple = “i686-pc-win32”%class.classDer = type { i8 }
define i32 @_Z1fv() {
entry:
%x = alloca %class.classDer, align 1
%call = call i32 @_ZN8classDer4get1Ev(%class.classDer* %x)
ret i32 %call
}
define linkonce_odr i32 @_ZN8classDer4get1Ev(%class.classDer* %this) nounwind align 2 {
entry:
%this.addr = alloca %class.classDer*, align 4
store %class.classDer* %this, %class.classDer** %this.addr, align 4
%this1 = load %class.classDer** %this.addr
ret i32 1
}
As can you see no remarks in the output about base and friend types
Also I tried to get TemplateTypeParameter/TemplateValueParameter in such a way for some template class but the results were “similar”
What can you propose to solve this problems and get full/maximum debug information after clang.
Thanks in advance.
