Bug ID: 107080
Summary: ICE in verify_symtab_nodes using _Float64x with long
double
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: jsm28 at gcc dot gnu.org
CC: jakub at gcc dot gnu.org
Target Milestone: ---
Target: x86_64-* i?86-* ia64-*
Compiling the following C++ test for x86_64 (or i686 or ia64) produces an ICE,
no optimization or other options required (presumably introduced by the _FloatN
/ _FloatNx support for C++).
template<typename> struct S;
template<> struct S<long double>
{
static int call (long double x, long double y) throw ()
{
return 3;
}
};
template<> struct S<_Float64x>
{
static int call (_Float64x x, _Float64x y) throw ()
{
return 3;
}
};
template<typename T1, typename T2>
inline int
g (T1 x, T2 y) throw ()
{
typedef decltype (x + y) T3;
return S<T3>::call (x, y);
}
int
f ()
{
return g (0.0f64x, 0.0f64x) + g (0.0f64x, 0.0L);
}
t.cc:31:1: error: Two symbols with same comdat_group are not linked by the
same_comdat_group list.
