Bug ID: 59851
Summary: Support sparse-style __attribute__((nocast)) (type
attribute)
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: hpa at zytor dot com
Created attachment 31862
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=31862&action=edit
Example source file
The sparse static C language checker has a type attribute
__attribute__((nocast))
... which issues a warning if a type is implicitly converted unless it is
exactly the same type (changes in constness is permitted, presumably changes in
volatility *should* be permitted as well).
The attached example file produces:
nocast.c:11:24: warning: implicit cast to nocast type
nocast.c:23:24: warning: implicit cast to nocast type
