2.1.112 --min_array_alignment=opt
This option enables you to specify the minimum alignment of arrays.
Syntax
--min_array_alignment=opt
Where:
opt
specifies the minimumalignment of arrays. The value of opt is:
1 byte alignment, or unaligned
2 two-byte, halfword alignment
4 four-byte, word alignment
8 eight-byte, doubleword alignment.
Default
If you do not specify a --min_array_alignment option, the compiler assumes
--min_array_alignment=1.
Example
Compiling the following code with --min_array_alignment=8 gives the alignment
described in the comments:
char arr_c1[1]; // alignment == 8
char c1; // alignment == 1
