Subject: gcc: __alignof__ not working correctly
To: [EMAIL PROTECTED]
X-Mailer: bug 3.3.7
Delivered-To: [EMAIL PROTECTED]
Package: gcc
Version: 1:2.95.2-20
Severity: normal
According to the documentation,
: When the operand of `__alignof__' is an lvalue rather than a type,
: the value is the largest alignment that the lvalue is known to have.
: It may have this alignment as a result of its data type, or because it
: is part of a structure and inherits alignment from that structure. For
: example, after this declaration:
:
: struct foo { int x; char y; } foo1;
:
: the value of `__alignof__ (foo1.y)' is probably 2 or 4, the same as
: `__alignof__ (int)', even though the data type of `foo1.y' does not
: itself demand any alignment.
However,
$ cat a.c
#include <stdio.h>
#include <netinet/ip_icmp.h>
int main() {
struct icmp foo;
printf("%d\n", __alignof__(foo.icmp_dun));
printf("%d\n", __alignof__(foo.icmp_data));
return 0;
}
$ make a
cc a.c -o a
$ ./a
4
1
$
where struct icmp is defined as,
struct icmp
{
u_int8_t icmp_type; /* type of message, see below */
u_int8_t icmp_code; /* type sub code */
u_int16_t icmp_cksum; /* ones complement checksum of struct */
union
{
u_char ih_pptr; /* ICMP_PARAMPROB */
struct in_addr ih_gwaddr; /* gateway address */
struct ih_idseq /* echo datagram */
{
u_int16_t icd_id;
u_int16_t icd_seq;
} ih_idseq;
u_int32_t ih_void;
/* ICMP_UNREACH_NEEDFRAG -- Path MTU Discovery (RFC1191) */
struct ih_pmtu
{
u_int16_t ipm_void;
u_int16_t ipm_nextmtu;
} ih_pmtu;
struct ih_rtradv
{
u_int8_t irt_num_addrs;
u_int8_t irt_wpa;
u_int16_t irt_lifetime;
} ih_rtradv;
} icmp_hun;
#define icmp_pptr icmp_hun.ih_pptr
#define icmp_gwaddr icmp_hun.ih_gwaddr
#define icmp_id icmp_hun.ih_idseq.icd_id
#define icmp_seq icmp_hun.ih_idseq.icd_seq
#define icmp_void icmp_hun.ih_void

#define icmp_nextmtu icmp_hun.ih_pmtu.ipm_nextmtu
#define icmp_num_addrs icmp_hun.ih_rtradv.irt_num_addrs
#define icmp_wpa icmp_hun.ih_rtradv.irt_wpa
#define icmp_lifetime icmp_hun.ih_rtradv.irt_lifetime
union
{
struct
{
u_int32_t its_otime;
u_int32_t its_rtime;
u_int32_t its_ttime;
} id_ts;
struct
{
struct ip idi_ip;
/* options and then 64 bits of data */
} id_ip;
struct icmp_ra_addr id_radv;
u_int32_t id_mask;
u_int8_t id_data[1];
} icmp_dun;
#define icmp_otime icmp_dun.id_ts.its_otime
#define icmp_rtime icmp_dun.id_ts.its_rtime
#define icmp_ttime icmp_dun.id_ts.its_ttime
#define icmp_ip icmp_dun.id_ip.idi_ip
#define icmp_radv icmp_dun.id_radv
#define icmp_mask icmp_dun.id_mask
#define icmp_data icmp_dun.id_data
};
So something is amiss here. I've reproduced this with gcc-2.95 2.95.3.ds3-4
as well.
