linux-user: Define target alignment size
Datatype alignment can be found using following application:
int main(void)
{
printf("alignof(short) %ld\n", __alignof__(short));
printf("alignof(int) %ld\n", __alignof__(int));
printf("alignof(long) %ld\n", __alignof__(long));
printf("alignof(long long) %ld\n", __alignof__(long long));
}
This patch includes following alignments:
i386
alignof(short) 2
alignof(int) 4
alignof(long) 4
alignof(long long) 8
x86_64
alignof(short) 2
alignof(int) 4
alignof(long) 8
alignof(long long) 8
arm
alignof(short) 2
alignof(int) 4
alignof(long) 4
alignof(long long) 4
m68k (680x0)
alignof(short) 2
alignof(int) 2
alignof(long) 2
alignof(long long) 2
mips
alignof(short) 2
alignof(int) 4
alignof(long) 4
alignof(long long) 8
ppc
alignof(short) 2
alignof(int) 4
alignof(long) 4
alignof(long long) 8
for other targets, use by default (2,4,4,8).
Please, update for your favorite target...
