/* Increase alignment of struct if an array's offset is multiple of alignment of
|
||||||
|
vector type corresponding to it's scalar type.
|
||||||
|
For the below test-case:
|
||||||
|
offsetof(e) == 8 bytes.
|
||||||
|
i) For arm: let x = alignment of vector type corresponding to int,
|
||||||
|
x == 8 bytes.
|
||||||
|
Since offsetof(e) % x == 0, set DECL_ALIGN(a, b, c) to x.
|
||||||
|
ii) For aarch64, ppc: x == 16 bytes.
|
||||||
|
Since offsetof(e) % x != 0, don't increase alignment of a, b, c.
