Bug ID: 96493
Summary: powerpc local call linkage failure
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: amodra at gmail dot com
Target Milestone: ---
/* -O2 -mcpu=power8 */
static int __attribute__ ((target("cpu=power10"),noclone,noinline))
local_func (int x)
{
return x;
}
int main()
{
return local_func (0);
}
results in a linker complaint "call to `local_func' lacks nop, can't restore
toc; (toc save/adjust stub)".
rs6000.md call_local et al patterns can't be allowed to match when
caller/callee disagree about r2 usage.
