Bug ID: 21284
Summary: Preprocessor warning when redefining keywords
Product: clang
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: Frontend
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
Could the preprocessor output a warning when someone redefines something that
shouldn't be redefined, like:
an identifier with special meaning:
#define override const
a keyword:
#define break continue
an alternative representation:
#define and or
a literal:
#define 1 2
#define "hello" "world"
#define 2. 3.
escape sequences... there are probably a lot of things that shouldn't be
redefined.
