From f2f9e7ecc1f02bfe5da83c38cf356ea96d428c6d Mon Sep 17 00:00:00 2001 From: Ulrich Weigand Date: Mon, 11 Dec 2017 15:26:26 +0100 Subject: [MPFR] Fix regression on 32-bit host systems When converting parts of the mantissa to MPFR, we need to make sure to do an *unsigned* conversion. Since we convert at most 32 bits at a time, stored in an unsigned long, this doesn't matter on systems where "long" is larger than 32 bits. But on systems where it is 32 bits, we can get conversion errors. gdb/ChangeLog 2017-12-11 Ulrich Weigand * target-float.c (mpfr_float_ops::from_target): Use mpfr_set_ui instead of mpfr_set_si to convert mantissa bits. --- gdb/target-float.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'gdb/target-float.c') diff --git a/gdb/target-float.c b/gdb/target-float.c index b40b641..9b14609 100644 --- a/gdb/target-float.c +++ b/gdb/target-float.c @@ -1312,7 +1312,7 @@ mpfr_float_ops::from_target (const struct floatformat *fmt, mant = get_field (from, order, fmt->totalsize, mant_off, mant_bits); - mpfr_set_si (tmp.val, mant, MPFR_RNDN); + mpfr_set_ui (tmp.val, mant, MPFR_RNDN); mpfr_mul_2si (tmp.val, tmp.val, exponent - mant_bits, MPFR_RNDN); mpfr_add (to.val, to.val, tmp.val, MPFR_RNDN); exponent -= mant_bits; -- cgit v1.1
