------- Comment #9 from JonathanDBrandmeyer at eaton dot com 2009-06-17 17:16 -------
Similarly, I would like the following to work as an extension to the anonymous
union support:
Given a structure like:
struct foo {
int a;
union {
int b;
float c;
};
int d;
};
I want to initialize it with a statement like:
struct foo value_of_foo = { .a = 0, .b = 1, .d = 2 };
instead of what is currently required, with braces around the initialization of
'foo::b':
struct foo value_of_foo = { .a = 0, { .b = 1 }, .d = 2 };
This is a natural extension of the ability to access members 'b' and 'c'
without tagging their union type.

------- Comment #11 from jan dot cornelis at gmail dot com 2009-08-27 14:57 -------
An example program that shows 3 different methods. Only one works (see comment)
As I used the names for each field, I assumed that all 3 examples should work.
#include <inttypes.h>
#include <stdio.h>
struct a_t {
uint16_t a;
uint16_t b;
union {
uint8_t c;
uint16_t d;
};
};
#if (1)
struct a_t alfa = {
.a = 1,
.b = 2,
.c = 3, //Will not work
};
#elif (0)
struct a_t alfa = {
.a = 1,
.b = 2,
{.c = 3}, //works
};
#elif (0)
struct a_t alfa = {
.a = 1,
{.c= 2}, //Does not work
.b = 3,
}
#endif
int main(void)
{
//alfa.c = 4;
//alfa.d = 5;
printf("%20s:%d\n","alfa.a",alfa.a);
printf("%20s:%d\n","alfa.b",alfa.b);
printf("%20s:%d\n","alfa.c",alfa.c);
printf("%20s:%d\n","alfa.d",alfa.d);
return 0;
}

This "bug" is causing me difficulty porting from an EDG-based compiler to
gcc-4.4.3. EDG implemented "assignment" and "initialization" as having the
same namespace.

C1x anonymous structures and unions will likely require a fix for this.

> {.c= 2}, //Does not work
For sake of documentation, with versions from before the fix the second method
did not always work. It seems to depend also on the ordering of the members in
the anonymous union. If .c is the first, second or third member of the union
it seems to work. It does not work for the fourth and following members.
Really puzzling.
