Hi everyone,
I met a problem with anonymous structs/unions. When the following
piece of code is compiled with clang with -fms-extensions, clang will
report an error "no member named 'a' in 's2'".
typedef struct
{
struct s1
{
int a;
};
} s2;
void foo()
{
s2 b;
b.a=0;
}
I tested both the svn version and the 3.0 release version of clang,
the result is the same. Tagged anonymous structs/unions cannot not be
correctly compiled by clang. However, gcc and the microsoft compiler
both have no problem with the above code.
Since I want the problem fixed ASAP, I plan to investigate some time.
In the meanwhile, I'm also new with clang, and need some help with
solving the problem.
So, can anybody gives a hint about where I should look at and how the
problem can be best fixed.
Thanks,
-Jianjiang
