| // 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. |
