hi,

I have a problem with return some smalll struct in registers, instead of 
memory.
I added -freg-struct-return option to C flags, but compiler omitted it. 
My sample code looks like:

1

typedef struct

2

{

3

  unsigned int a;

4

  unsigned int b;

5

} my_struct;

6

7

my_struct my_func ( unsigned int a, unsigned int b )

8

{

9

  my_struct s;

10

11

  s.a = a;

12

  s.b = b;

13

14

  return s;

15

}

compiled with specified flags

1

CFLAGS  = -c -Os -freg-struct-return -mthumb -mbig-endian -save-temps

as a result I got

1

my_func:

2

str  r1, [r0, #4]

3

str  r2, [r0]

4

bx  lr

but I expected something like

1

my_func:

2

mov  r2, r0

3

mov  r0, r1

4

mov  r1, r2

5

bx  lr

I'm using latest yagarto build but I noticed that problem on other 
toolchain too. Thanks for any hints.

best regards,
