HX> All

HX> I have the following on a GCC question ask for your help.

HX> For example, we have the following code foo.C :

HX> class A{
HX>    int a;
HX>    float b;
HX> };

HX> int main(){
HX>   int var1;
HX>   char var2;
HX>   float var3;
HX>   A  var4;

HX>   return 0;
HX> }

HX> Can gcc provide a report to tell the size of all the variables in the
HX> subroutine above? For example, var1=4.

HX> As you know, using
HX>    gcc -fdump-translation-unit foo.C
HX> we can get a foo.C.tu file which incluing many information about size, etc.
HX> Can we get the information of the size of all the variables in foo.C.tu?
HX> What does the items in foo.C.tu meant?

HX> Do you have any advice on this problem? I could not find an proper option to
HX> report the size of variables in GCC mannule.

HX> Thank you very much for your kind help.
HX> Best regards,
