Bug ID: 77925
Summary: Add __builtin_issubnormal
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: jsm28 at gcc dot gnu.org
Target Milestone: ---
TS 18661-1 defines an issubnormal type-generic floating-point classification
macro. GCC should have a corresponding type-generic built-in function
__builtin_issubnormal. As with other such type-generic classification
functions it should be included in the cases in c-typeck.c:convert_arguments
that remove excess precision.
