ldbl-96: Set -1 to "int sign_exponent:16"
ieee_long_double_shape_type has
typedef union
{
long double value;
struct
{
...
int sign_exponent:16;
...
} parts;
} ieee_long_double_shape_type;
Clang issues an error:
../sysdeps/ieee754/ldbl-96/test-totalorderl-ldbl-96.c:49:2: error: implicit truncation from 'int' to bit-field changes value from 65535 to -1 [-Werror,-Wbitfield-constant-conversion]
49 | SET_LDOUBLE_WORDS (ldnx, 0xffff,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
50 | tests[i] >> 32, tests[i] & 0xffffffffULL);
|
Use -1, instead of 0xffff, to silence Clang.
