Bug ID: 16032
Summary: soft-fp division spurious exceptions
Product: glibc
Version: 2.18
Status: NEW
Severity: normal
Priority: P2
Component: soft-fp
Assignee: unassigned at sourceware dot org
Reporter: jsm28 at gcc dot gnu.org
CC: joseph at codesourcery dot com
The soft-fp macros _FP_DIV_MEAT_2_udiv and _FP_DIV_MEAT_4_udiv, when dividing
two numbers with equal mantissas, produce a result with the exponent one too
low and the overflow bit set, resulting in spurious underflows if that exact
result is (plus or minus) the least normal value.
