Bug ID: 116069
Summary: tautological-compare warnings observed only with
-save-temps
Product: gcc
Version: 14.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: jbeulich at suse dot com
Target Milestone: ---
In a construct using a macro like
# define iommu_call(ops, fn, args...) ({ \
ASSERT((ops) == &iommu_ops); \
alternative_call(iommu_ops.fn, ## args); \
})
no warning appears when compiling normally, but a warning is raised on every
use site when using -save-temps. Together with -Werror this causes builds to
fail. (For context, this is an arch override for something that has a common
default of
# define iommu_call(ops, fn, args...) ((ops)->fn(args))
.)
Bug 78497 is somewhat related, yet there aren't any comments here to retain
(with -C, as suggested there).
