Packed struct for LLVM

typedef struct __attribute__ ((packed))          √

{

    int a ;

    char b ;

} TEST_T ;

Size: 5 Bytes

Putting it in the end as below won't work!! Also, aligned(1) does not work either!

typedef struct

{

    int a ;

    char b ;

} TEST_T __attribute__ ((packed)) ;   X

Size: 8 Bytes

typedef struct

{

    int a ;

    char b ;

} TEST_T __attribute__ ((aligned(1))) ;   X

Size: 8 Bytes

typedef struct __attribute__ ((aligned(1))) ;   X

{

    int a ;

    char b ;

} TEST_T ;
