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... Signed-off-by: Laurent Vivier <laurent@vivier.eu> Signed-off-by: Riku Voipio <riku.voipio@nokia.com>
