Bug ID: 71610
Summary: Improve location for "warning: ISO C restricts
enumerator values to range of ‘int’ [-Wpedantic]"?
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: ch3root at openwall dot com
Target Milestone: ---
Only the first token of the offending value is underlined for this warning.
Underlining all the value (like in clang) seems to be better.
Source code:
----------------------------------------------------------------------
int main()
{
enum { c = -3000000000 };
}
----------------------------------------------------------------------
Results:
----------------------------------------------------------------------
$ gcc -std=c11 -pedantic -Wall -Wextra -O3 test.c && ./a.out
test.c: In function ‘main’:
test.c:3:14: warning: ISO C restricts enumerator values to range of ‘int’
[-Wpedantic]
enum { c = -3000000000 };
^
----------------------------------------------------------------------
gcc version: gcc (GCC) 7.0.0 20160616 (experimental)
For comparison:
----------------------------------------------------------------------
$ clang -std=c11 -Weverything -O3 test.c && ./a.out
test.c:3:10: warning: ISO C restricts enumerator values to range of 'int'
(-3000000000 is too small) [-Wpedantic]
enum { c = -3000000000 };
^ ~~~~~~~~~~~
1 warning generated.
