Fix parentheses error in iconvconfig.c and ld-collate.c [BZ #24372]
|
|
|
00db10 |
|
|
|
00db10 |
When -Werror=parentheses is in use, iconvconfig.c builds fail with:
|
|
|
00db10 |
|
|
|
00db10 |
iconvconfig.c: In function ‘write_output’:
|
|
|
00db10 |
iconvconfig.c:1084:34: error: suggest parentheses around ‘+’ inside ‘>>’ [-Werror=parentheses]
|
|
|
00db10 |
hash_size = next_prime (nnames + nnames >> 1);

This patch adds parentheses to the expression. Not where suggested by
|
|
|
00db10 |
the compiler warning, but where it produces the expected result, i.e.:
|
|
|
00db10 |
where it has the effect of multiplying nnames by 1.5.
|
|
|
00db10 |
|
|
|
00db10 |
Likewise for elem_size in ld-collate.c.
