Bug ID: 107724
Summary: __builtin_{l,ll}floor* and __builtin_{l,ll}ceil* are
not documented
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Keywords: documentation
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: pinskia at gcc dot gnu.org
Target Milestone: ---
I found this while looking quickly into PR 107723, these two sets of built-ins
are not documented. While __builtin_{l,ll}round* set is documented.
The floor and ceil sets are even an extension on top and not part of any
standard as far as I can tell even. They are mostly used to optimize to one
instruction for many targets.
