Bug ID: 78874
Summary: Manual describes "-Wno-aggressive-loop-optimizations"
as if without "no-"
Product: gcc
Version: 6.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: jzwinck at gmail dot com
Target Milestone: ---
The gcc and g++ man pages say:
-Wno-aggressive-loop-optimizations
Warn if in a loop with constant number of iterations the compiler detects
undefined behavior in some statement during one or more of the iterations.
The "no-" here is a mistake: -Waggressive-loop-optimizations enables the
message and -Wno-* turns it off.
