// Per PR26619, check that for referenced static const of floating-point type,
// we emit its constant value in debug info.
//
// NOTE that __fp16 is assumed to be 16 bits, float is assumed to be
// 32 bits, and double is assumed to be 64 bits.  Size of long double
// is not known (for example, it is 64 bits for hexagon-unknown--elf,
// but 128 bits for x86_64-unknown-linux-gnu).  Therefore, we specify
// target triples where it has a known size, and check accordingly:
// for the absence of a constant (CHECK-LDlg) when the size exceeds 64
// bits, and for the presence of a constant (CHECK-LDsm) but not its
// value when the size does not exceed 64 bits.
//
// NOTE that PR26619 is not yet fixed for types greater than 64 bits.
