Burst Inference Failure 6

Explanation

Consider the packedness and byte alignment of user-defined structures in the interface. This message reports the bursting algorithm has determined that the given user-defined type has insufficient alignment. Identify the correct byte alignment of the user-defined type and specify it via attributes in the source code.

Example

//////////// ORIGINAL ////////////
struct mystruct {
  char a;
  short b;
};
 
void foo(mystruct *a, mystruct *b) {
  for( int i = 0; i < 256; ++i )
    b[i] = a[i];
}
 
//////////// UPDATED ////////////
struct mystruct {
  char a;
  short b;
} __attribute__((packed, aligned(4)));
 
void foo(mystruct *a, mystruct *b) {
  for( int i = 0; i < 256; ++i )
    b[i] = a[i];
}
