Bug ID: 92660
Summary: overflow warning message enhancement
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: jg at jguk dot org
Target Milestone: ---
Could GCC, for both C and C++ output the bitsize on the overflow warning ?
const int n = 41111111111;
#1 with x86-64 gcc (trunk)
<source>:1:15: warning: overflow in conversion from 'long int' to 'int' changes
value from '41111111111' to '-1838561849' [-Woverflow]
1 | const int n = 41111111111;
| ^~~~~~~~~~~
Suggestion:
<source>:1:15: warning: overflow in conversion from 'long int' (64bit) to 'int'
(32bit) changes value from '41111111111' to '-1838561849' [-Woverflow]
