Hi Devs,
debug info emitted by llvm does not contain DW_AT_Location for Formal
parameter
if it is an aggregate like below case
1) aggregate contain more than 4 homogeneous and size more than 128 bits
i.e.
typedef struct{
int a,b,c,d,e;
}mystruct;
void foo(mystruct ms){
}
2) aggregate contain hetrogeneous type and size more than 128 bits.
i.e.
typedef struct{
int a,b;
float c,d,e;
}mystruct;
void foo(mystruct ms){
}
This occur only when aarch64 is used, not with arm and x86.
like to know community thoughts wether this can be considered as bug or it's
an abi restriction.
