Bug ID: 58203
Summary: memset/memcpy are discarded with -flto
Product: gcc
Version: 4.8.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: kukyakya at gmail dot com
It might be a duplicate of bug 51205 but it's happening again.
[test.cpp]
typedef void (*action_t)(const unsigned char*);
extern "C" void _start(action_t action)
{
const unsigned char foo[256] = {};
action(foo);
}
typedef __SIZE_TYPE__ size_t;
extern "C"
void*
//__attribute__((externally_visible)) // Workaround
memset(void* dst, int c, size_t len)
{
unsigned char * d = (unsigned char*)dst;
while(len--)
*d++ = c;
return dst;
}
[error]
