Const-type Static Variables without Initial Values

In versions before 2.02, const-type static variables with initial values were output first, but from this revision, const-type static variables are aligned in the data area in order of their definition regardless of the existence of initial values.

Example

const int a=1;
const int b;
const int c=2;

 

[Result of compilation for versions before 2.02.00]

_a:
    .lword 00000001H
_c:
    .lword 00000002H ; The variables with initial values are output first.
_b:
    .lword 00000000H
