Bug ID: 99492
Summary: double and double _Complex not aligned consistently on
AIX
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: dje at gcc dot gnu.org
Target Milestone: ---
Target: powerpc-ibm-aix*
extern "C" int printf(const char *, ...);
struct C {
char c1;
double _Complex c2;
};
struct D {
char c1;
double c2;
};
int main() {
printf("%lu\n", __alignof(double _Complex));
printf("offsetof C.c2: %lu %lu\n", __builtin_offsetof(struct C, c2),
(unsigned long)&((struct C*)0)->c2);
printf("%lu\n", __alignof(double));
printf("offsetof D.c2: %lu %lu\n", __builtin_offsetof(struct D, c2),
(unsigned long)&((struct D*)0)->c2);
return 0;
}
xlC/xlClang/clang on AIX all agree that D.c2 is at offset 4.
