Bug ID: 95780
Summary: target_clones treats internal visibility different
from static functions
Product: gcc
Version: 10.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: yyc1992 at gmail dot com
Target Milestone: ---
Again using the code in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95778. If
the static function `f2` is changed to `visibility("internal")`, i.e.
```
__attribute__((visibility("internal"),noinline,target_clones("default,avx2")))
int f2(int *p)
{
asm volatile ("" :: "r"(p) : "memory");
return *p;
}
__attribute__((noinline,target_clones("default,avx2"))) int g2(int *p)
{
return f2(p);
}
```
the call to `f2` will then use the PLT again. Without `target_clone` the two
has similar effects and both produce a direct call.
