We currently have no way of dumping REAL_VALUE_TYPEs when debugging. Tested on a gdb session examining the real value 10.0:
(gdb) p min $9 = {cl = 1, decimal = 0, sign = 0, signalling = 0, canonical = 0, uexp = 4, sig = {0, 0, 11529215046068469760}} (gdb) p debug (min) 0x0.ap+4 OK for trunk? gcc/ChangeLog: * real.cc (debug): New. --- gcc/real.cc | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) diff --git a/gcc/real.cc b/gcc/real.cc index 73bbac645d9..a31b256a47b 100644 --- a/gcc/real.cc +++ b/gcc/real.cc @@ -1900,6 +1900,22 @@ real_to_decimal (char *str, const REAL_VALUE_TYPE *r_orig, size_t buf_size, digits, crop_trailing_zeros, VOIDmode); } +DEBUG_FUNCTION void +debug (const REAL_VALUE_TYPE *r) +{ + char s[60]; + real_to_hexadecimal (s, r, sizeof (s), 0, 1); + fprintf (stderr, "%s\n", s); +} + +DEBUG_FUNCTION void +debug (const REAL_VALUE_TYPE &r) +{ + char s[60]; + real_to_hexadecimal (s, &r, sizeof (s), 0, 1); + fprintf (stderr, "%s\n", s); +} + /* Render R as a hexadecimal floating point constant.
