Bug ID: 16678
Summary: Wrong behavior for large integer literal with -std=c89
Product: clang
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Frontend
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
Testcase (with -std=c89 on a target where long is 32 bits):
extern int a[__LONG_MAX__ == 2147483647 ? 1 : -1];
extern int a[-2147483648 > 0 ? 1 : -1];
There should be no errors on this testcase. clang currently prints an error.
(There might be a similar issue in the preprocessor; the C89 rules aren't
really clear.)
