Directs the compiler to align the variable to a specified boundary and a specified offset.
For portability on Linux* OS, you should use the syntax form
__attribute__((aligned(n[, off]))). This form is compatible with the GNU compiler.
- Specifies the alignment. The compiler will align the variable to ann-byte boundary.
- Optional. Specifies the offset. If this argument is omitted, the value is 0.
This keyword directs the compiler to align the variable to an
n-byte boundary with offset
n-byte boundary. The address of the variable is
If you require 8-byte alignment, we recommend you specify 16 for
n, instead of 8. When 8 is used, the compiler interprets the value as a suggestion and you may not get the requested 8-byte alignment, depending on various heuristics.
