Bug ID: 107377
Summary: Warn about duplicate enum values?
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
CC: mpolacek at gcc dot gnu.org
Target Milestone: ---
Noticed that while investigating PR107364:
enum processor_vendor
{
VENDOR_INTEL = 1,
VENDOR_AMD,
VENDOR_ZHAOXIN,
VENDOR_OTHER,
VENDOR_CENTAUR,
VENDOR_CYRIX,
VENDOR_NSC,
BUILTIN_VENDOR_MAX = VENDOR_OTHER,
VENDOR_MAX
};
As one can see VENDOR_CENTAUR == 5, but VENDOR_MAX is also == 5 as
BUILTIN_VENDOR_MAX points to 4 and thus VENDOR_MAX == 5.
Maybe we can warn about 2 enum values that have the same value and none of them
is defined with '= some_value'. What do you think?
