(gdb) p/x sect->common.flags & ~0x100000
$4 = 0x200000
(gdb) p/x flags
$5 = 0x200200
Note 0x100000 is SECTION_DECLARED which is masked out in the check.
#define SECTION_WRITE 0x00200 /* data is writable */
Writable comes from:
#2 0x08748aaa in default_named_section_asm_out_constructor (symbol=0xb7de9270,
priority=65535)
at /home/apinski/src/gcc-fsf/work/gcc/gcc/varasm.c:1525
1525 sec = get_section (".ctors", SECTION_WRITE, NULL);
So this is an internal issue, right?
Here is a testcase without using -fprofile-generate/-fprofile-arch:
void (*const __CTOR_LIST__[1]) (void) __attribute__
((section(".ctors")))
= { (void (*) (void)) -1 };
void __libc_global_ctors (void)
{
run_hooks (__CTOR_LIST__);
}
static void f(void) __attribute__((constructor));
static void f(void)
{
__builtin_printf("Hi.\n");
}
